    "content": "# Electrum - Lightweight Bitcoin client\n\n```\nLicence: MIT Licence\nAuthor: Thomas Voegtlin\nLanguage: Python (>= 3.10)\nHomepage: https://electrum.org/\n```\n\n[![Build Status](https://api.cirrus-ci.com/github/spesmilo/electrum.svg?branch=master)](https://cirrus-ci.com/github/spesmilo/electrum)\n[![Test coverage statistics](https://coveralls.io/repos/github/spesmilo/electrum/badge.svg?branch=master)](https://coveralls.io/github/spesmilo/electrum?branch=master)\n[![Help translate Electrum online](https://d322cqt584bo4o.cloudfront.net/electrum/localized.svg)](https://crowdin.com/project/electrum)\n\n\n## Getting started\n\n_(If you've come here looking to simply run Electrum,\n[you may download it here](https://electrum.org/#download).)_\n\nElectrum itself is pure Python, and so are most of the required dependencies,\nbut not everything. The following sections describe how to run from source, but here\nis a TL;DR:\n\n```\n$ sudo apt-get install libsecp256k1-dev\n$ ELECTRUM_ECC_DONT_COMPILE=1 python3 -m pip install --user \".[gui,crypto]\"\n```\n\n### Not pure-python dependencies\n\n#### Qt GUI\n\nIf you want to use the Qt interface, install the Qt dependencies:\n```\n$ sudo apt-get install python3-pyqt6\n```\n\n#### libsecp256k1\n\nFor elliptic curve operations,\n[libsecp256k1](https://github.com/bitcoin-core/secp256k1)\nis a required dependency.\n\nIf you \"pip install\" Electrum, by default libsecp will get compiled locally,\nas part of the `electrum-ecc` dependency. This can be opted-out of,\nby setting the `ELECTRUM_ECC_DONT_COMPILE=1` environment variable.\nFor the compilation to work, besides a C compiler, you need at least:\n```\n$ sudo apt-get install automake libtool\n```\nIf you opt out of the compilation, you need to provide libsecp in another way, e.g.:\n```\n$ sudo apt-get install libsecp256k1-dev\n```\n\n#### cryptography\n\nDue to the need for fast symmetric ciphers,\n[cryptography](https://github.com/pyca/cryptography) is required.\nInstall from your package manager (or from pip):\n```\n$ sudo apt-get install python3-cryptography\n```\n\n#### hardware-wallet support\n\nIf you would like hardware wallet support,\n[see this](https://github.com/spesmilo/electrum-docs/blob/master/hardware-linux.rst).\n\n\n### Running from tar.gz\n\nIf you downloaded the official package (tar.gz), you can run\nElectrum from its root directory without installing it on your\nsystem; all the pure python dependencies are included in the 'packages'\ndirectory. To run Electrum from its root directory, just do:\n```\n$ ./run_electrum\n```\n\nYou can also install Electrum on your system, by running this command:\n```\n$ sudo apt-get install python3-setuptools python3-pip\n$ python3 -m pip install --user .\n```\n\nThis will download and install the Python dependencies used by\nElectrum instead of using the 'packages' directory.\nIt will also place an executable named `electrum` in `~/.local/bin`,\nso make sure that is on your `PATH` variable.\n\n\n### Development version (git clone)\n\n_(For OS-specific instructions, see [here for Windows](contrib/build-wine/README_windows.md),\nand [for macOS](contrib/osx/README_macos.md))_\n\nCheck out the code from GitHub:\n```\n$ git clone https://github.com/spesmilo/electrum.git\n$ cd electrum\n$ git submodule update --init\n```\n\nRun install (this should install dependencies):\n```\n$ python3 -m pip install --user -e .\n```\n\nCreate translations (optional):\n```\n$ sudo apt-get install gettext\n$ ./contrib/locale/build_locale.sh electrum/locale/locale electrum/locale/locale\n```\n\nFinally, to start Electrum:\n```\n$ ./run_electrum\n```\n\n### Run tests\n\nRun unit tests with `pytest`:\n```\n$ pytest tests -v\n```\n(can be parallelized with `-n auto` option, using [`pytest-xdist`](https://github.com/pytest-dev/pytest-xdist) plugin)\n\nTo run a single file, specify it directly like this:\n```\n$ pytest tests/test_bitcoin.py -v\n```\n\n## Creating Binaries\n\n- [Linux (tarball)](contrib/build-linux/sdist/README.md)\n- [Linux (AppImage)](contrib/build-linux/appimage/README.md)\n- [macOS](contrib/osx/README.md)\n- [Windows](contrib/build-wine/README.md)\n- [Android](contrib/android/Readme.md)\n\n\n## Contributing\n\nAny help testing the software, reporting or fixing bugs, reviewing pull requests\nand recent changes, writing tests, or helping with outstanding issues is very welcome.\nImplementing new features, or improving/refactoring the codebase, is of course\nalso welcome, but to avoid wasted effort, especially for larger changes,\nwe encourage discussing these on the issue tracker or IRC first.\n\nBesides [GitHub](https://github.com/spesmilo/electrum),\nmost communication about Electrum development happens on IRC, in the\n`#electrum` channel on Libera Chat. The easiest way to participate on IRC is\nwith the web client, [web.libera.chat](https://web.libera.chat/#electrum).\n\nPlease improve translations on [Crowdin](https://crowdin.com/project/electrum).\n"

One user sent funds to one such address\n    and hence lost money. (see spesmilo/electrum-locale#46)\n  - We added some automated safeguards to try and prevent this in the future,\n    including basic regexes and an LLM proofreader. We also made the ongoing\n    git diffs for updating the frozen translations much smaller to make it\n    realistic to ~review. (see spesmilo/electrum-locale#47, #49, #51)\n  - However, the best solution would be per-language human review.\n    If we had 1-3 proofreaders per language on Crowdin, we could restrict\n    the set of translated strings that gets included in the binaries to the\n    \"proofreader-approved\" strings. We ask interested people to start contributing\n    and apply to be proofreaders. To get proofreader permissions, send us an email\n    or come to irc, with your crowdin username and some proof of work (such as\n    activity on crowdin in our or another project, contributions to open-source,\n    having an established identity on github/bitcointalk/stackoverflow/..., etc\n    -- just prove being a human and being well-intentioned).\n    (see https://github.com/spesmilo/electrum-locale/issues/47#issuecomment-3914866337)\n\n# Release 4.7.0 (Jan 22, 2026)\n * Qt GUI (desktop):\n   -

While the\n   licence remains unchanged, we ask users to agree with the fact that\n   we are not a custodial service or a money transmitter. The Terms of\n   Use screen also makes it clear that all issues are to be resolved\n   in public, and that there is no user support via private channels.\n * Nostr support: (using new dependency: electrum-aionostr)\n   Electrum now uses Nostr in the context of submarine swaps,\n   and in several plugins. Electrum will not connect to Nostr\n   by default, only if required.\n * Submarine swaps over Nostr: The Electrum client will connect to\n   Nostr in order to discover submarine swap providers, and to perform\n   related RPCs. This means that:\n    - Anyone can become a swap provider (you need to run an Electrum\n      daemon with the 'swapserver' plugin). Submarine swap providers\n      advertise their fees and their liquidity on Nostr.\n      See https://electrum.readthedocs.io/en/latest/swapserver.html\n      for set-up documentation.\n    - Submarine swap providers do not need to provide an HTTP\n      endpoint, since RPCs are performed via Nostr. They also do not\n      need to have public lightning channels.\n    - Because a decentralized service needs to be trustless, the\n      option to perform zero-confirmation swaps has been removed from\n      Electrum.\n    Note that Electrum connections to Nostr relays are only initiated\n    when the user uses the swap service, and the nostr public key used\n    by the client is ephemeral. In contrast, swap providers use a\n    persisted identity.\n * Third-party plugins:\n   - Electrum supports the installation of plugins distributed by\n     third-parties as ZIP files. While it has long been possible to\n     install third-party plugins when running Electrum from python\n     sources, the same is now possible when using desktop binaries\n     (Windows, MacOS, Linux). Third-party plugins are installed as ZIP\n     files in the user's electrum data directory.\n   - In order to prevent plugin installation by malware, third-party\n     plugins can only be enabled if the user enters a plugin\n     authorization password (distinct from the wallet password).\n     Setting up that plugin authorization password requires\n     administrator permissions on the local machine; a\n     password-derived public key must be written in the system.\n * Lightning:\n   - Anchor channels (#9264): Newly created channels use\n       anchor commitments by default. Since sweeping outputs from anchor\n       channels may require external UTXOs, lightning can no longer be\n       enabled in wallets that do not have a software keystore (hardware\n       wallets, watching-only wallets).  Existing wallets that are in that\n       situation cannot create new channels.\n   - wallets with anchor channels must always have utxos available (#9536)\n   - support added for onion messages (only CLI for now) (#9039)\n   - lots of fixes and improvements (#8857, #8547, #9700, #9083, ...)\n * Qt Desktop GUI:\n   - migrate from Qt5 to Qt6 (#9189)\n   - new: screenshot \"protection\" on Windows (#9898). Inspired by Windows\n     Recall, by default screenshots will contain black rectangles in\n     place of the Electrum windows, to try to avoid leaking secret keys.\n     This is opt-out using a config variable.\n   - exposed option to connect to only a single server (--oneserver)\n   - Wallet file encryption:\n     - Non-multisig hardware wallet files can now be encrypted with\n       either using the hardware device or (new) a password. (#5561)\n     - The option to have a password-protected wallet without file\n       encryption has been removed from the Qt GUI. It is still possible\n       to create such a wallet using the command line.\n   - Wallet unlocking:\n     - Wallets can be unlocked in the Qt GUI. When a password-protected\n       wallet is unlocked, its password is kept in memory, and signing\n       transactions will not require to enter the password. The unlocked\n       state is rendered by the 'open lock' icon in the status bar.\n     - If a wallet needs to sweep anchor channel outputs using extra\n       UTXOs, the operations will be performed without requiring the\n       user password if the wallet is unlocked. If the wallet is locked,\n       the status bar will show a 'password required' button.\n   - Transaction batching: When creating a new payment, if the\n     output can be added to an existing mempool transaction, the 'New\n     transaction' window will show a drop-down menu, proposing a list of\n     transactions that can be batched with the current payment. This\n     replaces the previous 'batch' option checkbox, and gives more\n     control to the user.\n   - Keystore enabling/disabling (Qt):\n     - It is now possible to add a seed\n       to an existing watching-only wallet, or to a keystore within a\n       multisig wallet. Similarly, it is possible to pair a watching-only\n       keystore with a hardware device. These operations are performed\n       from the 'Wallet Information' dialog.\n   - Lightning address contacts:\n     - It is now possible to create contacts with (lnurl type) lightning\n       addresses as payment identifier.\n   - show warnings on wallet close if there are sensitive pending operations,\n     e.g. when in the middle of doing a swap (#9715)\n   - some performance improvements for large wallets (#9958, #9967, #9968)\n   - qr-reader: macos: add runtime requesting of camera permission (#9955)\n * Accounting rules: In order to properly handle on-chain transactions\n   created by lightning channel force closures, we consider that funds\n   successfully redeemed from a script with several possible\n   recipients have never left the final recipient's wallet. This\n   avoids having to write balance changes that are cancelled\n   later. The corresponding addresses are rendered in the GUI as\n   'accounting addresses' (in orange).\n * New plugins:\n   - Nostr Wallet Connect: This plugin allows remote control of\n     Electrum lightning wallets via Nostr NIP-47. (#9675)\n   - Nostr Cosigner: This plugin facilitates the exchange of\n     PSBTs between cosigners of a multisig wallet. It replaces the\n     former 'Cosigner pool' plugin. Instead of relying on a central\n     server, it uses Nostr to send/receive PSBTs. (#9261)\n   - Timelock Recovery: A timelock based inheritance scheme.\n     See timelockrecovery.com (#9589)\n * CLI:\n   - The command line help has been improved; parameters are\n     documented in the same docstring as the command they belong to.\n   - If the --wallet parameter passed to a command is a simple filename,\n     it is now interpreted as relative to the users wallets directory,\n     rather than to the current working directory.\n   - Plugins may add extra commands to the CLI. Plugin commands must\n     be prefixed with the plugin's internal name.\n   - Support for hold invoices.\n   - new commands:\n     - listconfig, helpconfig, unsetconfig\n     - onchain_capital_gains (was previously a field of onchain_history)\n     - {add,settle,cancel,check}_hold_invoice\n     - send_onion_message, get_blinded_path_via\n     - wait_for_sync\n * General:\n   - Mitigate against dust attacks; Add option to avoid spending from\n     used addresses.

Fixing this required adding a\n     new field (local_payment_pubkey) to the channel backup\n     import/export format and bumping its version number\n     (v0->v1). Both v0 and v1 can be imported, and we only export v1\n     backups. When you force close a channel, the GUI will prompt you\n     to save a backup. In that case, you must export the backup using\n     the updated Electrum, and not rely on a backup made with an older\n     release of Electrum.  Note that if you request a force close from\n     the remote node or co-op close, you do not need to save a channel\n     backup.\n   - fix: we would sometimes attempt sending MPP even if not supported\n     by the invoice (2cf6173c)\n * QML GUI:\n   - fix lnurl-pay when config.BTC_AMOUNTS_ADD_THOUSANDS_SEP is True\n     (5b4df759)\n * Hardware wallets:\n   - Trezor: support longer than 9 character PIN codes (#8526)\n   - Jade: support more custom-built DIY Jade devices (#8546)\n * Builds/binaries:\n   - include AppStream metainfo.xml in tarballs (#8501)\n * fix: exceptions in some callbacks got lost and not logged (3e6580b9)\n\n\n# Release 4.4.5 (June 20, 2023)\n * Hardware wallets:\n   - jade: fix regression in sign_transaction (#8463)\n * Lightning:\n   - fix \"rebalance_channels\" function (#8468)\n * enforce that we run with python asserts enabled,\n   regardless of platform (d1c88108)\n\n\n# Release 4.4.4 (May 31, 2023)\n * QML GUI:\n   - fix creating multisig wallets involving BIP39 seeds (#8432)\n   - fix \"cannot scroll to open a lightning channel\" (#8446)\n   - wizard: \"confirm seed\" screen to normalize whitespaces (#8442)\n   - fix assert on address details screen (#8420)\n * Qt GUI:\n   - better handle some expected errors in SwapDialog (#8430)\n * libsecp256k1: bump bundled version to 0.3.2 (10574bb1)\n\n\n# Release 4.4.3 (May 11, 2023)\n * Intentionally break multisig wallets that have heterogeneous master\n   keys. Versions 4.4.0 to 4.4.2 of Electrum for Android did not check\n   that master keys used the same script type. This may have resulted\n   in the creation of multisig wallets that cannot be spent from\n   with any existing version of Electrum.

The \"source-only\" tarball excludes\n   compiled locale files, generated protobuf files, and does not\n   vendor our runtime python dependencies (the packages/ folder).\n * fix os.chmod when running in tmpfs on Linux (#7681)\n * (Qt GUI) some improvements for high-DPI monitors (38881129)\n * bring kivy request dialog more in-line with Qt (#7929)\n * rm support of \"legacy\" (without static_remotekey) LN channels.\n   Opening these channels were never supported in a release version,\n   only during development prior to the first lightning-capable\n   release. Wallets with such channels will have to close them.\n   (1f403d1c, 7b8e257e)\n * Qt: fix duplication of some OS notifications on onchain txs (#7943)\n * fix multiple recent regressions:\n    - handle NotEnoughFunds when trying to pay LN invoice (#7920)\n    - handle NotEnoughFunds when trying to open LN channel (#7921)\n    - labels of payment requests were not propagated to\n      history/addresses (#7919)\n    - better default labels of outgoing txs (#7942)\n    - kivy: dust-valued requests could not be created for LN (#7928)\n    - when closing LN channels, future (timelocked) txs were not\n      shown in history (#7930)\n    - kivy: fix deleting \"local\" tx from history (#7933)\n    - kivy: fix paying amountless LN invoice (#7935)\n    - Qt: better handle unparseable URIs (#7941)\n\n\n# Release 4.3.0 - (August 5, 2022)\n\n * This version introduces a set of UI modifications that simplify the\n   use of Lightning. The idea is to abstract payments from the payment\n   layer, and to suggest solutions when a lightning payment is hindered\n   by liquidity issues.\n    - Invoice unification: on-chain and lightning invoices have been\n      merged into a unique type of invoice, and the GUI has a single\n      'create request' button. Unified invoices contain both a\n      lightning invoice and an onchain fallback address.\n    - The receive tab of the GUI can display, for each payment\n      request, a lightning invoice, a BIP21 URI, or an onchain\n      address. If the request is paid off-chain, the associated\n      on-chain address will be recycled in subsequent requests.\n    - The receive tab displays whether a payment can be received using\n      Lightning, given the current channel liquidity. If a payment\n      cannot be received, but may be received after a channel\n      rebalance or a submarine swap, the GUI will propose such an\n      operation.\n    - Similarly, if channels do not have enough liquidity to pay a\n      lightning invoice, the GUI will suggest available alternatives:\n      rebalance existing channels, open a new channel, perform a\n      submarine swap, or pay to the provided onchain fallback address.\n    - A single balance is shown in the GUI. A pie chart reflects how\n      that balance is distributed (on-chain, lightning, unconfirmed,\n      frozen, etc).\n    - The semantics of the wallet balance has been modified: only\n      incoming transactions are considered in the 'unconfirmed' part\n      of the balance. Indeed, if an outgoing transaction does not get\n      mined, that is not going to decrease the wallet balance. Thus,\n      change outputs of outgoing transactions are not subtracted from\n      the confirmed balance. (Before this change, the arithmetic\n      values of both incoming and outgoing transactions were added to\n      the unconfirmed balance, and could potentially cancel\n      each other.)\n\n * In addition, the following new features are worth noting:\n    - support for the Blockstream Jade hardware wallet (#7633)\n    - support for LNURL-pay (LUD-06) (#7839)\n    - updated trampoline feature bit in invoices (#7801)\n    - the claim transactions of reverse swaps are not broadcast until\n      the parent transaction is confirmed. This can be overridden by\n      manually broadcasting the local transaction.\n    - the fee of submarine swap transactions can be bumped (#7724)\n    - better error handling for trampoline payments, which should\n      improve payment success rate (#7844)\n    - channel backups are removed automatically when the corresponding\n      channel is redeemed (#7513)\n\n\n# Release 4.2.2 - (May 27, 2022)\n * Lightning:\n   - watching onchain outputs: significant perf. improvements (#7781)\n   - enforce relative order of some msgs during chan reestablishment,\n     lack of which can lead to unwanted force-closures (#7830)\n   - fix: in case of a force-close containing incoming HTLCs, we were\n     redeeming all HTLCs that we know the preimage for. This might\n     publish the preimage of an incomplete MPP. (1a5ef554, e74e9d8e)\n * Hardware wallets:\n   - smarter pairing during sign_transaction (238619f1)\n   - keepkey: fix pairing with device using a workaround (#7779)\n * fix AppImage failing to run on certain systems (#7784)\n * fix \"Automated BIP39 recovery\" not scanning change paths (#7804)\n * bypass network proxy for localhost electrum server (#3126)\n * security fix: remove support of \"file://\" URIs from BIP70 payment\n   requests, which could be used to trigger \"open()\" on arbitrary files\n   (see https://github.com/spesmilo/electrum/security/advisories/GHSA-4fh4-hx35-r355)\n\n\n# Release 4.2.1 - (March 26, 2022)\n * Binaries:\n   - Windows: we are dropping support for Windows 7.

While our initial Lightning release was mostly\nabout implementing the protocol, this release brings features that are\nspecifically aimed at keeping Electrum lightweight and trustless,\nwhile avoiding single points of failure. Most of the features listed\nbelow are user-visible.\n * The wallet creation wizard no longer asks for a seed type, and\n   creates segwit wallets with bech32 addresses. Older seed types can\n   still be created with the command line.\n * Paid invoices (both incoming and outgoing) are automatically\n   removed from the send/receive lists of the GUI (one confirmation is\n   needed for onchain invoices). Once removed from the list, invoice\n   details can still be accessed from the transaction history. In Qt,\n   invoice lists have been renamed to 'Sending queue' and 'Receiving\n   queue'.\n * Lightning:\n    - recoverable channels (see below)\n    - trampoline payments (see below)\n    - support multi-part-payment\n    - support upfront-shutdown-script\n * Recoverable channels (option):\n   - Recovery data is added to the channel funding transaction using\n     an OP_RETURN. This makes it possible to recover a static backup\n     of the channel from the wallet seed. Please note that static\n     backups only allow users to request a force-close of the channel\n     with the remote node, so that funds not locked in HTLCs can be\n     recovered. This assumes that the remote node is still online, did\n     not lose its data, and accepts to force close the channel.\n   - This option is only available for standard wallets with an\n     Electrum seed. It is not available for hardware wallets, because\n     it requires a deterministic derivation of the nodeID. It is also\n     not available in watching-only wallets, for the same reason. If a\n     wallet can have recoverable channels but has an old nodeID, users\n     who want to use that feature need to close all their existing\n     channels, and to restore their wallet from seed.\n   - Channel recovery data uses 20 bytes (16 bytes of the remote\n     NodeID plus 4 magic bytes) and is encrypted so that only the\n     wallet that owns it can decrypt it. However, blockchain analysis\n     will be able to tell that the transaction was probably created by\n     Electrum.\n   - If the 'use recoverable channels' option is enabled, other nodes\n     cannot open a channel to Electrum.\n   - If a channel is force-closed, the information in the on-chain\n     backup is not sufficient to retrieve the funds in the to_local\n     output, in case the wallet is lost in a boating accident before\n     expiration of the CSV delay. For that reason, an additional\n     backup is presented to the user if they force-close a channel.\n * Trampoline routing (option): Trampoline is a solution that allows\n   light clients to delegate path-finding on the Lightning Network, so\n   that they do not have to download the entire network\n   graph. Trampoline routing was originally proposed by Bastien\n   Teinturier and is used in the Phoenix wallet. Here is how\n   Trampoline works in Electrum:\n   - Trampoline is enabled by default, in order to prevent unwanted\n     download of the network gossip. If trampoline is disabled, the\n     gossip will be downloaded, regardless of the existence of\n     channels.\n   - Because there is no discovery mechanism for trampoline nodes, the\n     list of available trampolines is hardcoded in the client (it will\n     remain so until support for trampoline routing is announced in\n     gossip). 3 trampoline nodes are currently available on mainnet:\n     ACINQ, Electrum and Hodlister.\n   - If Trampoline is enabled:\n      - payments use trampoline routing.\n      - gossip is disabled.\n      - the wallet can only open channels with trampoline nodes.\n      - pre-existing channels with non-trampoline nodes are frozen for\n        sending.\n   - There are two types of trampoline payments: legacy and trampoline\n     end-to-end. Legacy payments are possible with any receiver, but\n     they offer less privacy than end-to-end trampoline\n     payments. Electrum decides whether to perform legacy or\n     end-to-end based on the features in the invoice:\n       - OPTION_TRAMPOLINE_ROUTING_OPT (bit 25) for Electrum\n       - OPTION_TRAMPOLINE_ROUTING_OPT_ECLAIR (bit 51) for Eclair/Phoenix\n   - When performing a legacy payment, Electrum will add a second\n     trampoline node to the route in order to protect the privacy of\n     the payer and payee. It will fall back to a single trampoline if\n     the two-trampoline strategy has failed for all trampolines.\n     (Note: two-trampoline payments are currently not possible if the\n     first trampoline is the ACINQ node, and is disabled for that\n     node.)\n   - Similar to Phoenix, the fee and CLTV delay are found by\n     trial-and-error. If there is a second trampoline in the route, we\n     use the same fee/CLTV for both. This trial-and-error is\n     temporary; the final specification should add fee information in\n     the failure messages, so that we will be able to better fine-tune\n     trampoline fees.\n * Qt: The increase fee dialog now has advanced options, and offers\n   the choice between different RBF strategies.\n * Watchtowers: The 'use_local_watchtower' feature is deprecated, and\n   it has been removed from the Qt GUI. The 'use_remote_watchtower'\n   setting has been renamed to 'use_watchtower'.\n * Password unification (Android only): When the Android app is\n   started, the entered password is checked against all wallets in\n   the directory. If the test passes:\n    - all wallets are encrypted\n    - new wallets will use the unified password\n    - password updates are performed on all wallets\n   Whether the password is unified can be seen in the GUI: In the\n   'Settings' dialog, the description for the password setting is\n   'Change password for this wallet' if the password is not unified,\n   and becomes 'Change password' if password is unified.\n * Submarine swaps are now available on kivy/android.\n * Android PIN reset: If the password is unified, the PIN can be reset\n   by providing the password.\n * Android: on-chain fees have been removed from the settings\n   dialog. Instead, the fee slider is shown to the user every time an\n   on-chain transaction will be performed (sending a payment, opening\n   a channel, initiating a submarine swap)\n * BIP-0350: use bech32m for witness version 1+ addresses (4315fa43).\n   We have supported sending to any witness version since Electrum\n   3.0, using BIP-0173 (bech32) addresses. BIP-0350 makes a breaking\n   change in address encoding, and recommends using a new encoding\n   (bech32m) for sending to witness version 1 and later.\n * Block explorer: allow setting a custom URL in Qt GUI (#6965)\n\n\n# Release 4.0.9 - (Dec 18, 2020)\n * fixes a regression introduced in 4.0.8, that prevents from\n   paying BIP70 invoices (#6859)\n * reflect frozen channels and disconnected peers in the displayed\n   'can send/can receive' amounts.\n\n# Release 4.0.8 - (Dec 17, 2020)\n * fix decoding BIP21 URIs with uppercase schema (d40bedb2)\n * psbt: put full derivation paths into PSBT by default (c8155129)\n * invoices: allow address-reuse (#6609, #6852)\n * A few other minor bugfixes.\n\n# Release 4.0.7 - (Dec 9, 2020)\n * kivy: fix open channel with 'max' amount\n * kivy: fix regression introduced in last release (a9fc440)\n * other minor GUI fixes\n * Dependencies: as part of adapting to new dnspython (#6828),\n   - python-ecdsa is no longer needed at all,\n   - cryptography is now required (min 2.6), the user can no\n     longer choose between cryptography and pycryptodomex\n\n# Release 4.0.6 - (Dec 4, 2020)\n * Fix 'Max' button issue for submarine swaps button (#6770)\n * Fix 'Max' button in kivy (#6169)\n * Various fixes for Kivy/Android install wizard\n * More robust account keypath for BitBox02 (#6766)\n\n# Release 4.0.5 - (Nov 18, 2020)\n * Fix .dmg binary hanging on recently released macOS 11 Big Sur (#6461)\n * Lightning:\n   - bugfix: during LN channel opening, if the client crashed at the\n     wrong moment, the channel might not get fully persisted to disk,\n     and would need manual console-tinkering to recover (#6656)\n   - Lightning is enabled by default. Electrum will not connect to\n     the Lightning Network until the user opens a channel. (#6639)\n   - smarter node recommendation (to open channels with) (#6705)\n * user interface: some minor changes that aim to improve usability\n * Ledger:\n   - fix enumerating devices with new bitcoin app (1.5.1) (b78cbcff)\n   - fix compat with HW.1 (200f547a)\n * A few other minor bugfixes.\n\n# Release 4.0.4 - (Oct 15, 2020)\n * PSBT: fix regression in 4.0.3 where UTXO data was not included in\n   QR codes (#6600)\n * new feature: \"Cancel tx\" (#6641). The Qt/kivy GUI allows cancelling\n   an unconfirmed RBF tx by double-spending its inputs to self.\n * Windows binary:\n   - fix some issues with QR scanning by building zbar ourselves (#6593)\n   - when using setup exe, also install a debug binary (#6603)\n * Ledger: fix \"The derivation path is unusual\" warnings (#6512)\n   (needs Bitcoin app 1.4.8+ installed on device)\n * A few other minor bugfixes and usability improvements.\n\n# Release 4.0.3 - (Sep 11, 2020)\n * PSBT: restore compatibility with Bitcoin Core following CVE-2020-14199:\n   we now allow a PSBT input to have both UTXO and WITNESS_UTXO (#6429).\n   (PSBTs created since 4.0.1 already contained UTXO for segwit inputs)\n * Hardware wallets:\n   - bitbox02: better multisig UX: implement get_soft_device_id (#6386)\n   - coldcard: fix \"show address\" for multisig (#6517)\n   - all: run all device communication on a dedicated thread (#6561).\n     This should resolve some threading issues.\n * new feature: \"Automated BIP39 recovery\" (#6219, #6155)\n   When restoring from a BIP39 seed, add option to scan many known\n   derivation paths for history, and show them to user to choose from.\n * show derivation path of keystores in Qt GUI Wallet>Information (#4700)\n * fix \"signtransaction\" RPC command (#6502)\n * Dependencies: pyaes is no longer needed (#6563)\n * The tar.gz source dist now bundles make_libsecp256k1.sh, to help\n   users getting libsecp256k1 (#6323).\n * A few other minor bugfixes and usability improvements.\n\n# Release 4.0.2 - (July 8, 2020)\n - rm old corrupted non-bip70 invoices (#6345)\n - other minor fixes\n\n# Release 4.0.1 - (July 3, 2020)\n * Lightning Network support (experimental)\n   - Our implementation of Lightning relies on Electrum servers to\n     query channel states. Since servers can lie about the state of a\n     channel, users should either use a server that they trust, or\n     setup a private watchtower (see below). A watchtower is also\n     recommended for lightning wallets that remain offline for\n     extended periods of time (the default CSV 'to_self_delay' is 1\n     week). Please note that Electrum Personal Server (EPS) cannot be\n     used with lightning wallets, because channels funding addresses\n     are arbitrary.\n   - Lightning funds cannot be restored from seed. Instead, users need\n     to create static backups of their channels. Static backups cannot\n     be used to perform lightning transactions, they can only be used\n     to trigger a remote-force-close of a channel.\n   - Lightning-enabled wallet files must not be copied. Instead, a\n     backup of the wallet can be created from the Qt menu, and it will\n     contain static backups of all its channels. Backups can also be\n     exported for each channel (e.g. via QR code), and imported in\n     another wallet. Since backups are encrypted with a key derived\n     from the wallet's xpub, they can only be imported into another\n     instance of the same wallet, or a watch-only version of it. The\n     force-close is not triggered automatically when the backup is\n     imported; imported backups can live inside a wallet file.\n   - Lightning can be enabled in the GUI (Wallet>Information) or from\n     the CLI (init_lightning). Lightning is currently restricted to HD\n     p2wpkh wallets (including watch-only and hardware wallets). The\n     Qt GUI, CLI/RPC, and the kivy GUI (Android) all have LN support,\n     with feature-richness in that order.\n   - LN protocol details: dataloss_protect and static_remotekey are\n     required; varonion and payment_secret are implemented, MPP not yet.\n     Channels are not announced ('private'), forwarding is disabled.\n     We do not serve gossip queries, only consume them.\n   - Submarine swaps: the GUI integrates a service that offers\n     atomically exchanging on-chain and lightning bitcoins for a fee.\n     Electrum Technologies runs a central server for this, powered by\n     the Boltz backend.\n   - Watchtowers: Electrum can run a local watchtower (GUI setting),\n     or it can connect to a remote watchtower. A watchtower contains\n     pre-signed transactions and does not need your private keys. A\n     local watchtower will watch your channels whenever an Electrum\n     instance is running, without needing access to your wallet file.\n     An Electrum daemon can be configured to be used as a remote\n     watchtower by setting 'watchtower_address', 'watchtower_user' and\n     'watchtower_password'.\n * Partially Signed Bitcoin Transactions (PSBT, BIP-174) are supported\n   (#5721). The previous Electrum partial transaction format is no\n   longer supported, i.e. this is an incompatible change. Users should\n   make sure that all instances of Electrum they use to co-sign or\n   offline sign, are updated together.\n * Hardware wallets: several fixes in general; notable changes:\n   - The BitBox02 is now supported (#5993)\n   - Multisig support for Coldcard (#5440)\n   - Compatibility with latest Trezor fw (#6064, #6198, #5692)\n * Dependencies (see README for install instructions):\n   - libsecp256k1 is now required (previously optional). python-ecdsa\n     remains a dependency but it is now only used for DNSSEC.\n   - Added: either one of pycryptodomex or cryptography is now required,\n     mainly due to LN (previously pycryptodomex was optional, for fast AES)\n   - Removed: jsonrpclib-pelix, the JSON-RPC library used for CLI/daemon\n * Qt GUI: several changes, notably:\n   - Separation between output selection and transaction finalization.\n   - Coin selection moved to the Coins tab, and it affects all txns,\n     e.g. RBF fee-bumping, LN channel opens, submarine swaps.\n   - Editable tx preview dialog that allows e.g. changing the locktime,\n     toggling RBF, and manual coinjoins.\n * HTTP PayServer: The configuration of a bitcoin-accepting website\n   using Electrum has been simplified and requires fewer steps (see\n   documentation). The Payserver supports BIP70 and Lightning payments.\n * Android:\n   - We now build two APKs, one for ARMv7 and one for ARMv8\n   - The kivy GUI now supports importing BIP39 seeds\n   - Each wallet on kivy now can have a separate generic password,\n     using which the wallet files are encrypted. An optional PIN,\n     shared among all wallets, can be added to get prompted for spends.\n * The API of several CLI/RPC commands have changed, and several new\n   commands have been introduced (mainly for LN).\n * Distributables:\n   - The .tar.gz source dist is now built reproducibly.\n     Relatedly, we no longer distribute a .zip sdist.\n   - The MacOS binary now conforms to macOS 10.15; it is notarized\n     by Apple. This required bumping the min macOS version to 10.13.\n     Startup times should now be faster on 10.15. (#6128, #6225)\n * Transactions:\n   - we now grind low R for ECDSA signatures to match bitcoind (#5820)\n * Lots and lots of other minor bugfixes and improvements.\n\n\n# Release 3.3.8 - (July 11, 2019)\n\n * fix some bugs with recent bump fee (RBF) improvements (#5483, #5502)\n * fix #5491: watch-only wallets could not bump fee in some cases\n * appimage: URLs could not be opened on some desktop environments (#5425)\n * faster tx signing for segwit inputs for really large txns (#5494)\n * A few other minor bugfixes and usability improvements.\n\n\n# Release 3.3.7 - (July 3, 2019)\n\n * The AppImage Linux x86_64 binary and the Windows setup.exe\n   (so now all Windows binaries) are now built reproducibly.\n * Bump fee (RBF) improvements:\n   Implemented a new fee-bump strategy that can add new inputs,\n   so now any tx can be fee-bumped (d0a4366). The old strategy\n   was to decrease the value of outputs (starting with change).\n   We will now try the new strategy first, and only use the old\n   as a fallback (needed e.g. when spending \"Max\").\n * CoinChooser improvements:\n   - more likely to construct txs without change (when possible)\n   - less likely to construct txs with really small change (e864fa5)\n   - will now only spend negative effective value coins when\n     beneficial for privacy (cb69aa8)\n * fix long-standing bug that broke wallets with >65k addresses (#5366)\n * Windows binaries: we now build the PyInstaller boot loader ourselves,\n   as this seems to reduce anti-virus false positives (1d0f679)\n * Android: (fix) BIP70 payment requests could not be paid (#5376)\n * Android: allow copy-pasting partial transactions from/to clipboard\n * Fix a performance regression for large wallets (c6a54f0)\n * Qt: fix some high DPI issues related to text fields (37809be)\n * Trezor:\n   - allow bypassing \"too old firmware\" error (#5391)\n   - use only the Bridge to scan devices if it is available (#5420)\n * hw wallets: (known issue) on Win10-1903, some hw devices\n   (that also have U2F functionality) can only be detected with\n   Administrator privileges. (see #5420 and #5437)\n   A workaround is to run as Admin, or for Trezor to install the Bridge.\n * Several other minor bugfixes and usability improvements.\n\n\n# Release 3.3.6 - (May 16, 2019)\n\n * qt: fix crash during 2FA wallet creation (#5334)\n * fix synchronizer not to keep resubscribing to addresses of\n   already closed wallets (e415c0d9)\n * fix removing addresses/keys from imported wallets (#4481)\n * kivy: fix crash when aborting 2FA wallet creation (#5333)\n * kivy: fix rare crash when changing exchange rate settings (#5329)\n * A few other minor bugfixes and usability improvements.\n\n\n# Release 3.3.5 - (May 9, 2019)\n\n * The logging system has been overhauled (#5296).\n   Logs can now also optionally be written to disk, disabled by default.\n * Fix a bug in synchronizer (#5122) where client could get stuck.\n   Also, show the progress of history sync in the GUI. (#5319)\n * fix Revealer in Windows and MacOS binaries (#5027)\n * fiat rate providers:\n   - added CoinGecko.com and CoinCap.io\n   - BitcoinAverage now only provides historical exchange rates for\n     paying customers. Changed default provider to CoinGecko.com (#5188)\n * hardware wallets:\n   - Ledger: Nano X is now recognized (#5140)\n   - KeepKey:\n     - device was not getting detected using Windows binary (#5165)\n     - support firmware 6.0.0+ (#5205)\n   - Trezor: implemented \"seedless\" mode (#5118)\n * Coin Control in Qt: implemented freezing individual UTXOs\n   in addition to freezing addresses (#5152)\n * TrustedCoin (2FA wallets):\n   - better error messages (#5184)\n   - longer signing timeout (#5221)\n * Kivy:\n   - fix bug with local transactions (#5156)\n   - allow selecting fiat rate providers without historical data (#5162)\n * fix CPFP: the fees already paid by the parent were not included in\n   the calculation, so it always overestimated (#5244)\n * Testnet: there is now a warning when the client is started in\n   testnet mode as there were a number of reports of users getting\n   scammed through social engineering (#5295)\n * CoinChooser: performance of creating transactions has been improved\n   significantly for large wallets. (d56917f4)\n * Importing/sweeping WIF keys: stricter checks (#4638, #5290)\n * Electrum protocol: the client's \"user agent\" has been changed from\n   \"3.3.5\" to \"electrum/3.3.5\". Other libraries connecting to servers\n   can consider not \"spoofing\" to be Electrum. (#5246)\n * Several other minor bugfixes and usability improvements.\n\n\n# Release 3.3.4 - (February 13, 2019)\n\n * AppImage: we now also distribute self-contained binaries for x86_64\n   Linux in the form of an AppImage (#5042). The Python interpreter,\n   PyQt5, libsecp256k1, PyCryptodomex, zbar, hidapi/libusb (including\n   hardware wallet libraries) are all bundled. Note that users of\n   hw wallets still need to set udev rules themselves.\n * hw wallets: fix a regression during transaction signing that prompts\n   the user too many times for confirmations (commit 2729909)\n * transactions now set nVersion to 2, to mimic Bitcoin Core\n * fix Qt bug that made all hw wallets unusable on Windows 8.1 (#4960)\n * fix bugs in wallet creation wizard that resulted in corrupted\n   wallets being created in rare cases (#5082, #5057)\n * fix compatibility with Qt 5.12 (#5109)\n\n\n# Release 3.3.3 - (January 25, 2019)\n\n * Do not expose users to server error messages (#4968)\n * Notify users of new releases. Release announcements must be signed,\n   and they are verified byElectrum using a hardcoded Bitcoin address.\n * Hardware wallet fixes (#4991, #4993, #5006)\n * Display only QR code in QRcode Window\n * Fixed code signing on MacOS\n * Randomise locktime of transactions\n\n\n# Release 3.3.2 - (December 21, 2018)\n\n * Fix Qt history export bug\n * Improve network timeouts\n * Prepend server transaction_broadcast error messages with\n   explanatory message. Render error messages as plain text.\n\n\n# Release 3.3.1 - (December 20, 2018)\n\n * Qt: Fix invoices tab crash (#4941)\n * Android: Minor GUI improvements\n\n\n# Release 3.3.0 - Hodler's Edition (December 19, 2018)\n\n * The network layer has been rewritten using asyncio and aiorpcx.\n   In addition to easier maintenance, this makes the client\n   more robust against misbehaving servers.\n * The minimum python version was increased to 3.6\n * The blockchain headers and fork handling logic has been generalized.\n   Clients by default now follow chain based on most work, not length.\n * New wallet creation defaults to native segwit (bech32).\n * Segwit 2FA: TrustedCoin now supports native segwit p2wsh\n   two-factor wallets.\n * RBF batching (opt-in): If the wallet has an unconfirmed RBF\n   transaction, new payments will be added to that transaction,\n   instead of creating new transactions.\n * MacOS: support QR code scanner in binaries.\n * Android APK:\n   - build using Google NDK instead of Crystax NDK\n   - target API 28\n   - do not use external storage (previously for block headers)\n * hardware wallets:\n   - Coldcard now supports spending from p2wpkh-p2sh,\n     fixed p2pkh signing for fw 1.1.0\n   - Archos Safe-T mini: fix #4726 signing issue\n   - KeepKey: full segwit support\n   - Trezor: refactoring and compat with python-trezor 0.11\n   - Digital BitBox: support firmware v5.0.0\n * fix bitcoin URI handling when app already running (#4796)\n * Qt listings rewritten:\n   the History tab now uses QAbstractItemModel, the other tabs use\n   QStandardItemModel. Performance should be better for large wallets.\n * Several other minor bugfixes and usability improvements.\n\n\n# Release 3.2.4 - (December 30, 2018)\n\n * backport anti-phishing measures from master\n\n\n# Release 3.2.3 - (September 3, 2018)\n\n * hardware wallet: the Safe-T mini from Archos is now supported.\n * hardware wallet: the Coldcard from Coinkite is now supported.\n * BIP39 seeds: if a seed extension (aka passphrase) contained\n   multiple consecutive whitespaces or leading/trailing whitespaces\n   then the derived addresses were not following spec. This has been\n   fixed, and affected should move their coins. The wizard will show a\n   warning in this case. (#4566)\n * Revealer: the PRNG used has been changed (#4649)\n * fix Linux distributables: 'typing' was not bundled, needed for python 3.4\n * fix #4626: fix spending from segwit multisig wallets involving a Trezor\n   cosigner when using a custom derivation path\n * fix #4491: on Android, if user had set \"uBTC\" as base unit, app crashed\n * fix #4497: on Android, paying bip70 invoices from cold start did not work\n * Several other minor bugfixes and usability improvements.\n\n\n# Release 3.2.2 - (July 2nd, 2018)\n\n * Fix DNS resolution on Windows\n * Fix websocket bug in daemon\n\n\n# Release 3.2.1 - (July 1st, 2018)\n\n * fix Windows binaries: due to build process changes, the locale files\n   were not included; the language could not be changed from English\n * fix Linux distributables: wordlists were not included (#4475)\n\n\n# Release 3.2.0 - Satoshi's Vision (June 30, 2018)\n\n * If present, libsecp256k1 is used to speed up elliptic curve\n   operations. The library is bundled in the Windows, MacOS, and\n   Android binaries. On Linux, it needs to be installed separately.\n * Two-factor authentication is available on Android. Note that this\n   will only provide additional security if one time passwords are\n   generated on a separate device.\n * Semi-automated crash reporting is implemented for Android.\n * Transactions that are dropped from the mempool are kept in the\n   wallet as 'local', and can be rebroadcast. Previously these\n   transactions were deleted from the wallet.\n * The scriptSig and witness part of transaction inputs are no longer\n   parsed, unless actually needed. The wallet will no longer display\n   'from' addresses corresponding to transaction inputs, except for\n   its own inputs.\n * The partial transaction format has been incompatibly changed. This\n   was needed as for partial transactions the scriptSig/witness has to\n   be parsed, but for signed transactions we did not want to do the\n   parsing.  Users should make sure that all instances of Electrum\n   they use to co-sign or offline sign, are updated together.\n * Signing of partial transactions created with online imported\n   addresses wallets now supports significantly more\n   setups. Previously only online p2pkh address + offline WIF was\n   supported.  Now the following setups are all supported:\n   - online {p2pkh, p2wpkh-p2sh, p2wpkh} address + offline WIF,\n   - online {p2pkh, p2wpkh-p2sh, p2wpkh} address + offline seed/xprv,\n   - online {p2sh, p2wsh-p2sh, p2wsh}-multisig address + offline seeds/xprvs\n     (potentially distributed among several different machines)\n   Note that for the online address + offline HD secret case, you need\n   the offline wallet to recognize the address (i.e. within gap\n   limit).  Having an xpub on the online machine is still the\n   recommended setup, as this allows the online machine to generate\n   new addresses on demand.\n * Segwit multisig for bip39 and hardware wallets is now enabled.\n   (both p2wsh-p2sh and native p2wsh)\n * Ledger: offline signing for segwit inputs (#3302) This has already\n   worked for Trezor and Digital Bitbox. Offline segwit signing can be\n   combined with online imported addresses wallets.\n * Added Revealer plugin. ( https://revealer.cc ) Revealer is a seed\n   phrase back-up solution. It allows you to create a cold, analog,\n   multi-factor backup of your wallet seeds, or of any arbitrary\n   secret. The Revealer utilizes a transparent plastic visual one time\n   pad.\n * Fractional fee rates: the Qt GUI now displays fee rates with 0.1\n   sat/byte precision, and also allows this same resolution in the\n   Send tab.\n * Hardware wallets: a \"show address\" button is now displayed in the\n   Receive tab of the Qt GUI. (#4316)\n * Trezor One: implemented advanced/matrix recovery (#4329)\n * Qt/Kivy: added \"sat\" as optional base unit.\n * Kivy GUI: significant performance improvements when displaying\n   history and address list of large wallets; and transaction dialog\n   of large transactions.\n * Windows: use dnspython to resolve dns instead of socket.getaddrinfo\n   (#4422)\n * Importing minikeys: use uncompressed pubkey instead of compressed\n   (#4384)\n * SPV proofs: check inner nodes not to be valid transactions (#4436)\n * Qt GUI: there is now an optional \"dark\" theme (#4461)\n * Several other minor bugfixes and usability improvements.\n\n\n# Release 3.1.3 - (April 16, 2018)\n\n * Qt GUI: seed word auto-complete during restore\n * Android: fix some crashes\n * performance improvements (wallet, and Qt GUI)\n * hardware wallets: show debug message during device scan\n * Digital Bitbox: enabled BIP84 (p2wpkh) wallet creation\n * add regtest support (via --regtest flag)\n * other minor bugfixes and usability improvements\n\n# Release 3.1.2 - (March 28, 2018)\n\n * Kivy/android: request PIN on startup\n * Improve OSX build process\n * Fix various bugs with hardware wallets\n * Other minor bugfixes\n\n# Release 3.1.1 - (March 12, 2018)\n\n * fix #4031: Trezor T support\n * partial fix #4060: proxy and hardware wallet can't be used together\n * fix #4039: can't set address labels\n * fix crash related to coinbase transactions\n * MacOS: use internal graphics card\n * fix openalias related crashes\n * speed-up capital gains calculations\n * hw wallet encryption: re-prompt for passphrase if incorrect\n * other minor fixes.\n\n\n\n# Release 3.1.0 - (March 5, 2018)\n\n * Memory-pool based fee estimation. Dynamic fees can target a desired\n   depth in the memory pool. This feature is optional, and ETA-based\n   estimates from Bitcoin Core are still available. Note that miners\n   could exploit this feature, if they conspired and filled the memory\n   pool with expensive transactions that never get mined. However,\n   since the Electrum client already trusts an Electrum server with\n   fee estimates, activating this feature does not introduce any new\n   vulnerability. In addition, the client uses a hard threshold to\n   protect itself from servers sending excessive fee estimates. In\n   practice, ETA-based estimates have resulted in sticky fees, and\n   caused many users to overpay for transactions. Advanced users tend\n   to visit (and trust) websites that display memory-pool data in\n   order to set their fees.\n * Capital gains: For each outgoing transaction, the difference\n   between the acquisition and liquidation prices of outgoing coins is\n   displayed in the wallet history. By default, historical exchange\n   rates are used to compute acquisition and liquidation prices. These\n   values can also be entered manually, in order to match the actual\n   price realized by the user. The order of liquidation of coins is\n   the natural order defined by the blockchain; this results in\n   capital gain values that are invariant to changes in the set of\n   addresses that are in the wallet. Any other ordering strategy (such\n   as FIFO, LIFO) would result in capital gain values that depend on\n   the presence of other addresses in the wallet.\n * Local transactions: Transactions can be saved in the wallet without\n   being broadcast. The inputs of local transactions are considered as\n   spent, and their change outputs can be re-used in subsequent\n   transactions. This can be combined with cold storage, in order to\n   create several transactions before broadcasting them. Outgoing\n   transactions that have been removed from the memory pool are also\n   saved in the wallet, and can be broadcast again.\n * Checkpoints: The initial download of a headers file was replaced\n   with hardcoded checkpoints. The wallet uses one checkpoint per\n   retargeting period. The headers for a retargeting period are\n   downloaded only if transactions need to be verified in this period.\n * The 'privacy' and 'priority' coin selection policies have been\n   merged into one. Previously, the 'privacy' policy has been unusable\n   because it was was not prioritizing confirmed coins. The new policy\n   is similar to 'privacy', except that it de-prioritizes addresses\n   that have unconfirmed coins.\n * The 'Send' tab of the Qt GUI displays how transaction fees are\n   computed from transaction size.\n * The wallet history can be filtered by time interval.\n * Replace-by-fee is enabled by default. Note that this might cause\n   some issues with wallets that do not display RBF transactions until\n   they are confirmed.\n * Watching-only wallets and hardware wallets can be encrypted.\n * Semi-automated crash reporting\n * The SSL checkbox option was removed from the GUI.\n * The Trezor T hardware wallet is now supported.\n * BIP84: native segwit p2wpkh scripts for bip39 seeds and hardware\n   wallets can now be created when specifying a BIP84 derivation\n   path. This is usable with Trezor and Ledger.\n * Windows: the binaries now include ZBar, and QR code scanning should work.\n * The Wallet Import Format (WIF) for private keys that was extended in 3.0\n   is changed. Keys in the previous format can be imported, compatibility\n   is maintained. Newly exported keys will be serialized as\n   \"script_type:original_wif_format_key\".\n * BIP32 master keys for testnet once again have different version bytes than\n   on mainnet. For the mainnet prefixes {x,y,Y,z,Z}|{pub,prv}, the\n   corresponding testnet prefixes are   {t,u,U,v,V}|{pub,prv}.\n   More details and exact version bytes are specified at:\n   https://github.com/spesmilo/electrum-docs/blob/master/xpub_version_bytes.rst\n   Note that due to this change, testnet wallet files created with previous\n   versions of Electrum must be considered broken, and they need to be\n   recreated from seed words.\n * A new version of the Electrum protocol is required by the client\n   (version 1.2). Servers using older versions of the protocol will\n   not be displayed in the GUI.\n\n\n# Release 3.0.6 :\n  * Fix transaction parsing bug #3788\n\n# Release 3.0.5 : (Security update)\n\nThis is a follow-up to the 3.0.4 release, which did not completely fix\nissue #3374. Users should upgrade to 3.0.5.\n\n * The JSONRPC interface is password protected\n * JSONRPC commands are disabled if the GUI is running, except 'ping',\n   which is used to determine if a GUI is already running\n\n\n# Release 3.0.4 : (Security update)\n\n * Fix a vulnerability caused by Cross-Origin Resource Sharing (CORS)\n   in the JSONRPC interface. Previous versions of Electrum are\n   vulnerable to port scanning and deanonimization attacks from\n   malicious websites. Wallets that are not password-protected are\n   vulnerable to theft.\n * Bundle QR scanner with Android app\n * Minor bug fixes\n\n# Release 3.0.3\n  * Qt GUI: sweeping now uses the Send tab, allowing fees to be set\n  * Windows: if using the installer binary, there is now a separate shortcut\n    for \"Electrum Testnet\"\n  * Digital Bitbox: added support for p2sh-segwit\n  * OS notifications for incoming transactions\n  * better transaction size estimation:\n    - fees for segwit txns were somewhat underestimated (#3347)\n    - some multisig txns were underestimated\n    - handle uncompressed pubkeys\n  * fix #3321: testnet for Windows binaries\n  * fix #3264: Ledger/dbb signing on some platforms\n  * fix #3407: KeepKey sending to p2sh output\n  * other minor fixes and usability improvements\n\n# Release 3.0.2\n  * Android: replace requests tab with address tab, with access to\n    private keys\n  * sweeping minikeys: search for both compressed and uncompressed\n    pubkeys\n  * fix wizard crash when attempting to reset Google Authenticator\n  * fix #3248: fix Ledger+segwit signing\n  * fix #3262: fix SSL payment request signing\n  * other minor fixes.\n\n# Release 3.0.1\n  * minor bug and usability fixes\n\n# Release 3.0 - Uncanny Valley (November 1st, 2017)\n\n  * The project was migrated to Python3 and Qt5. Python2 is no longer\n    supported. If you cloned the source repository, you will need to\n    run \"python3 setup.py install\" in order to install the new\n    dependencies.\n\n  * Segwit support:\n\n    - Native segwit scripts are supported using a new type of\n      seed. The version number for segwit seeds is 0x100. The install\n      wizard will not create segwit seeds by default; users must\n      opt-in with the segwit option.\n\n    - Native segwit scripts are represented using bech32 addresses,\n      following BIP173. Please note that BIP173 is still in draft\n      status, and that other wallets/websites may not support\n      it. Thus, you should keep a non-segwit wallet in order to be\n      able to receive bitcoins during the transition period. If BIP173\n      ends up being rejected or substantially modified, your wallet\n      may have to be restored from seed. This will not affect funds\n      sent to bech32 addresses, and it will not affect the capacity of\n      Electrum to spend these funds.\n\n    - Segwit scripts embedded in p2sh are supported with hardware\n      wallets or bip39 seeds. To create a segwit-in-p2sh wallet,\n      trezor/ledger users will need to enter a BIP49 derivation path.\n\n    - The BIP32 master keys of segwit wallets are serialized using new\n      version numbers. The new version numbers encode the script type,\n      and they result in the following prefixes:\n\n         * xpub/xprv : p2pkh or p2sh\n         * ypub/yprv : p2wpkh-in-p2sh\n         * Ypub/Yprv : p2wsh-in-p2sh\n         * zpub/zprv : p2wpkh\n         * Zpub/Zprv : p2wsh\n\n      These values are identical for mainnet and testnet; tpub/tprv\n      prefixes are no longer used in testnet wallets.\n\n    - The Wallet Import Format (WIF) is similarly extended for segwit\n      scripts. After a base58-encoded key is decoded to binary, its\n      first byte encodes the script type:\n\n         * 128 + 0: p2pkh\n         * 128 + 1: p2wpkh\n         * 128 + 2: p2wpkh-in-p2sh\n         * 128 + 5: p2sh\n         * 128 + 6: p2wsh\n         * 128 + 7: p2wsh-in-p2sh\n\n      The distinction between p2sh and p2pkh in private key means that\n      it is not possible to import a p2sh private key and associate it\n      to a p2pkh address.\n\n  * A new version of the Electrum protocol is required by the client\n    (version 1.1). Servers using older versions of the protocol will\n    not be displayed in the GUI.\n\n  * By default, transactions are time-locked to the height of the\n    current block. Other values of locktime may be passed using the\n    command line.\n\n\n# Release 2.9.4 (security update)\n  * Backport security fixes from 3.0.5 after vulnerability was\n    discovered in JSONRPC interface.\n\n# Release 2.9.3\n  * fix configuration file issue #2719\n  * fix ledger signing of non-RBF transactions\n  * disable 'spend confirmed only' option by default\n\n# Release 2.9.2\n  * force headers download if headers file is corrupted\n  * add websocket to windows builds\n\n# Release 2.9.1\n  * fix initial headers download\n  * validate contacts on import\n  * command-line option for locktime\n\n# Release 2.9 - Independence (July 27th, 2017)\n  * Multiple Chain Validation: Electrum will download and validate\n    block headers sent by servers that may follow different branches\n    of a fork in the Bitcoin blockchain. Instead of a linear sequence,\n    block headers are organized in a tree structure. Branching points\n    are located efficiently using binary search. The purpose of MCV is\n    to detect and handle blockchain forks that are invisible to the\n    classical SPV model.\n  * The desired branch of a blockchain fork can be selected using the\n    network dialog. Branches are identified by the hash and height of\n    the diverging block. Coin splitting is possible using RBF\n    transaction (a tutorial will be added).\n  * Multibit support: If the user enters a BIP39 seed (or uses a\n    hardware wallet), the full derivation path is configurable in the\n    install wizard.\n  * Option to send only confirmed coins\n  * Qt GUI:\n    - Network dialog uses tabs and gets updated by network events.\n    - The gui tabs use icons\n  * Kivy GUI:\n    - separation between network dialog and wallet settings dialog.\n    - option for manual server entry\n    - proxy configuration\n  * Daemon: The wallet password can be passed as parameter to the\n    JSONRPC API.\n  * Various other bugfixes and improvements.\n\n\n# Release 2.8.3\n  * Fix crash on reading older wallet formats.\n  * TrustedCoin: remove pay-per-tx option\n\n# Release 2.8.2\n  * show paid invoices in history tab\n  * improve CPFP dialog\n  * fixes for trezor, keepkey\n  * other minor bugfixes\n\n# Release 2.8.1\n  * fix Digital Bitbox plugin\n  * fix daemon jsonrpc\n  * fix trustedcoin wallet creation\n  * other minor bugfixes\n\n# Release 2.8.0 (March 9, 2017)\n  * Wallet file encryption using ECIES: A keypair is derived from the\n    wallet password. Once the wallet is decrypted, only the public key\n    is retained in memory, in order to save the encrypted file.\n  * The daemon requires wallets to be explicitly loaded before\n    commands can use them. Wallets can be loaded using: 'electrum\n    daemon load_wallet [-w path]'. This command will require a\n    password if the wallet is encrypted.\n  * Invoices and contacts are stored in the wallet file and are no\n    longer shared between wallets. Previously created invoices and\n    contacts files may be imported from the menu.\n  * Fees improvements:\n    - Dynamic fees are enabled by default.\n    - Child Pays For Parent (CPFP) dialog in the GUI.\n    - RBF is automatically proposed for low fee transactions.\n  * Support for Segregated Witness (testnet only).\n  * Support for Digital Bitbox hardware wallet.\n  * The GUI shows a blue icon when connected using a proxy.\n\n# Release 2.7.18\n  * enforce https on exchange rate APIs\n  * use hardcoded list of exchanges\n  * move 'Freeze' menu to Coins (utxo) tab\n  * various bugfixes\n\n# Release 2.7.17\n  * fix a few minor regressions in the Qt GUI\n\n# Release 2.7.16\n  * add Testnet support (fix #541)\n  * allow daemon to be launched in the foreground (fix #1873)\n  * Qt: use separate tabs for addresses and UTXOs\n  * Qt: update fee slider with a network callback\n  * Ledger: new ui and mobile 2fa validation (neocogent)\n\n# Release 2.7.15\n  * Use fee slider for both static and dynamic fees.\n  * Add fee slider to RBF dialog (fix #2083).\n  * Simplify fee preferences.\n  * Critical: Fix password update issue (#2097). This bug prevents\n    password updates in multisig and 2FA wallets. It may also cause\n    wallet corruption if the wallet contains several master private\n    keys (such as 2FA wallets that have been restored from\n    seed). Affected wallets will need to be restored again.\n\n# Release 2.7.14\n  * Merge exchange_rate plugin with main code\n  * Faster synchronization and transaction creation\n  * Fix bugs #2096, #2016\n\n# Release 2.7.13\n  * fix message signing with imported keys\n  * add size to transaction details window\n  * move plot plugin to main code\n  * minor bugfixes\n\n# Release 2.7.12\n  various bugfixes\n\n# Release 2.7.11\n  * fix offline signing (issue #195)\n  * fix android crashes caused by threads\n\n# Release 2.7.10\n  * various fixes for hardware wallets\n  * improve fee bumping\n  * separate sign and broadcast buttons in Qt tx dialog\n  * allow spaces in private keys\n\n# Release 2.7.9\n  * Fix a bug with the ordering of pubkeys in recent multisig wallets.\n    Affected wallets will regenerate their public keys when opened for\n    the first time. This bug does not affect address generation.\n  * Fix hardware wallet issues #1975, #1976\n\n# Release 2.7.8\n  * Fix a bug with fee bumping\n  * Fix crash when parsing request (issue #1969)\n\n# Release 2.7.7\n  * Fix utf8 encoding bug with old wallet seeds (issue #1967)\n  * Fix delete request from menu (issue #1968)\n\n# Release 2.7.6\n * Fixes a critical bug with imported private keys (issue #1966). Keys\n   imported in Electrum 2.7.x were not encrypted, even if the wallet\n   had a password. If you imported private keys using Electrum 2.7.x,\n   you will need to import those keys again. If you imported keys in\n   2.6 and converted with 2.7.x, you don't need to do anything, but\n   you still need to upgrade in order to be able to spend.\n * Wizard: Hide seed options in a popup dialog.\n\n# Release 2.7.5\n * Add number of confirmations to request status. (issue #1757)\n * In the GUI, refer to passphrase as 'seed extension'.\n * Fix bug with utf8 encoded passphrases.\n * Kivy wizard: add a dialog for seed options.\n * Kivy wizard: add current word to suggestions, because some users\n   don't see the space key.\n\n# Release 2.7.4\n * Fix private key import in wizard\n * Fix Ledger display (issue #1961)\n * Fix old watching-only wallets (issue #1959)\n * Fix Android compatibility (issue #1947)\n\n# Release 2.7.3\n * fix Trezor and Keepkey support in Windows builds\n * fix sweep private key dialog\n * minor fixes: #1958, #1959\n\n# Release 2.7.2\n * fix bug in password update (issue #1954)\n * fix fee slider (issue #1953)\n\n# Release 2.7.1\n * fix wizard crash with old seeds\n * fix issue #1948: fee slider\n\n# Release 2.7.0 (Oct 2 2016)\n\n * The wallet file format has been upgraded. This upgrade is not\n   backward compatible, which means that a wallet upgraded to the 2.7\n   format will not be readable by earlier versions of\n   Electrum. Multiple accounts inside the same wallet are not\n   supported in the new format; the Qt GUI will propose to split any\n   wallet that has several accounts. Make sure that you have saved\n   your seed phrase before you upgrade Electrum.\n * This version introduces a separation between wallets types and\n   keystores types. 'Wallet type' defines the type of Bitcoin contract\n   used in the wallet, while 'keystore type' refers to the method used\n   to store private keys. Therefore, so-called 'hardware wallets' will\n   be referred to as 'hardware keystores'.\n * Hardware keystores:\n   - The Ledger Nano S is supported.\n   - Hardware keystores can be used as cosigners in multi-signature\n     wallets.\n   - Multiple hardware cosigners can be used in the same multisig\n     wallet. One icon per keystore is displayed in the satus bar. Each\n     connected device will co-sign the transaction.\n * Replace-By-Fee: RBF transactions are supported in both Qt and\n   Android. A warning is displayed in the history for transactions\n   that are replaceable, have unconfirmed parents, or that have very\n   low fees.\n * Dynamic fees: Dynamic fees are enabled by default. A slider allows\n   the user to select the expected confirmation time of their\n   transaction. The expected confirmation times of incoming\n   transactions is also displayed in the history.\n * The install wizards of Qt and Kivy have been unified.\n * Qt GUI (Desktop):\n   - A fee slider is visible in the in send tab\n   - The Address tab is hidden by default, can be shown with Ctrl-A\n   - UTXOs are displayed in the Address tab\n * Kivy GUI (Android):\n   - The GUI displays the complete transaction history.\n   - Multisig wallets are supported.\n   - Wallets can be created and deleted in the GUI.\n * Seed phrases can be extended with a user-chosen passphrase. The\n   length of seed phrases is standardized to 12 words, using 132 bits\n   of entropy (including 2FA seeds). In the wizard, the type of the\n   seed is displayed in the seed input dialog.\n * TrustedCoin users can request a reset of their Google Authenticator\n   account, if they still have their seed.\n\n\n# Release 2.6.4 (bugfixes)\n * fix coinchooser bug (#1703)\n * fix daemon JSONRPC (#1731)\n * fix command-line broadcast (#1728)\n * QT: add colors to labels\n\n# Release 2.6.3 (bugfixes)\n * fix command line parsing of transactions\n * fix signtransaction --privkey (#1715)\n\n# Release 2.6.2 (bugfixes)\n * fix Trustedcoin restore from seed (bug #1704)\n * small improvements to kivy GUI\n\n# Release 2.6.1 (bugfixes)\n * fix broadcast command (bug #1688)\n * fix tx dialog (bug #1690)\n * kivy: support old-type seed phrases in wizard\n\n# Release 2.6\n * The source code is relicensed under the MIT Licence\n * First official release of the Kivy GUI, with android APK\n * The old 'android' and 'gtk' GUIs are deprecated\n * Separation between plugins and GUIs\n * The command line uses jsonrpc to communicate with the daemon\n * New command: 'notify <address> <url>'\n * Alternative coin selection policy, designed to help preserve user\n   privacy. Enable it by setting the Coin Selection preference to\n   Privacy.\n * The install wizard has been rewritten and improved\n * Support minikeys as used in Casascius coins for private key import\n   and sweeping\n * Much improved support for TREZOR and KeepKey devices:\n   - full device information display\n   - initialize a new or wiped device in 4 ways:\n     1) device generates a new wallet\n     2) you enter a seed\n     3) you enter a BIP39 mnemonic to generate the seed\n     4) you enter a master private key\n   - KeepKey secure seed recovery (KeepKey only)\n   - change / set / disable PIN\n   - set homescreen (TREZOR only)\n   - set a session timeout.  Once a session has timed out, further use\n     of the device requires your PIN and passhphrase to be re-entered\n   - enable / disable passphrases\n   - device wipe\n   - multiple device support\n\n# Release 2.5.4\n * increase MIN_RELAY_TX_FEE to avoid dust transactions\n\n# Release 2.5.3 (bugfixes)\n * installwizard: do not allow direct copy-paste of the seed\n * installwizard: fix bug #1531 (starting offline)\n\n# Release 2.5.2 (bugfixes)\n * fix bug #1513 (client tries to broadcast transaction while not connected)\n * fix synchronization bug (#1520)\n * fix command line bug (#1494)\n * fixes for exchange rate plugin\n\n# Release 2.5.1 (bugfixes)\n * signatures in transactions were still using the old class\n * make sure that setup.py uses python2\n * fix wizard crash with trustedcoin plugin\n * fix socket infinite loop\n * fix history bug #1479\n\n# Release 2.5\n * Low-S values are used in signatures (BIP 62).\n * The Kivy GUI has been merged into master.\n * The Qt GUI supports multiple windows in the same process. When a\n   new Electrum instance is started, it checks for an already running\n   Electrum process, and connects to it.\n * The network layer uses select(), so all server communication is\n   handled by a single thread. Moreover, the synchronizer, verifier,\n   and exchange rate plugin now run as separate jobs within the\n   networking thread instead of as their own threads.\n * Plugins are revamped, particularly the exchange rate plugin.\n\n# Release 2.4.4\n * Fix bug with TrustedCoin plugin\n\n# Release 2.4.3\n * Support for KeepKey hardware wallet\n * Simplified Chinese wordlist\n * Minor bugfixes and GUI tweaks\n\n# Release 2.4.2\n * Command line can read arguments from stdin (pipe)\n * Speedup fee computation for large transactions\n * Various bugfixes\n\n# Release 2.4.1\n * Use ssl.PROTOCOL_TLSv1\n * Fix DNSSEC issues with ECDSA signatures\n * Replace TLSLite dependency with minimal RSA implementation\n * Dynamic Fees: using estimatefee value returned by server\n * Various GUI improvements\n\n# Release 2.4\n * Payment to DNS names storing a Bitcoin addresses (OpenAlias) is\n   supported directly, without activating a plugin. The verification\n   uses DNSSEC.\n * The DNSSEC verification code was rewritten. The previous code,\n   which was part of the OpenAlias plugin, is vulnerable and should\n   not be trusted (Electrum 2.0 to 2.3).\n * Payment requests can be signed using Bitcoin addresses stored\n   in DNS (OpenAlias). The identity of the requestor is verified using\n   DNSSEC.\n * Payment requests signed with OpenAlias keys can be shared as\n   bitcoin: URIs, if they are simple (a single address-type\n   output). The BIP21 URI scheme is extended with 'name', 'sig',\n   'time', 'exp'.\n * Arbitrary m-of-n multisig wallets are supported (n<=15).\n * Multisig transactions can be signed with TREZOR. When you create\n   the multisig wallet, just enter the xpub of your existing TREZOR\n   wallet.\n * Transaction fees set manually in the GUI are retained, including\n   when the user uses the '!' shortcut.\n * New 'email' plugin, that enables sending and receiving payment\n   requests by email.\n * The daemon supports Websocket notifications of payments.\n\n# Release 2.3.3\n * fix proxy settings (issue #1309)\n * improvements to the transaction dialog:\n    - request password after showing transaction\n    - show change addresses in yellow color\n\n# Release 2.3.2\n * minor bugfixes\n * updated ledger plugin\n * sort inputs/outputs lexicographically (BIP-LI01)\n\n# Release 2.3.1\n * patch a bug with payment requests\n\n# Release 2.3\n * Improved logic for the network layer.\n * More efficient coin selection. Spend oldest coins first, and\n   minimize the number of transaction inputs.\n * Plugins are loaded independently of the GUI. As a result, Openalias,\n   TrustedCoin and TREZOR wallets can be used with the command\n   line. Example: 'electrum payto <openalias> <amount>'\n * The command line has been refactored:\n  - Arguments are parsed with argparse.\n  - The inline help includes a description of options.\n  - Some commands have been renamed. Notably, 'mktx' and 'payto' have\n    been merged into a single command, with a --broadcast option.\n   Type 'electrum --help' for a complete overview.\n * The command line accepts the '!' syntax to send the maximum\n   amount available. It can be combined with the '--from' option.\n   Example: 'payto <destination> ! --from <from_address>'\n * The command line also accepts a '?' shortcut for private keys\n   arguments, that triggers a prompt.\n * Payment requests can be managed with the command line, using the\n   following commands: 'addrequest', 'rmrequest', 'listrequests'.\n   Payment requests can be signed with a SSL certificate, and published\n   as bip70 files in a public web directory. To see the relevant\n   configuration variables, type 'electrum addrequest --help'\n * Commands can be called with jsonrpc, using the 'jsonrpc' gui. The\n   jsonrpc interface may be called by php.\n\n# Release 2.2\n * Show amounts (thousands separators and decimal point)\n   according to locale in GUI\n * Show unmatured coins in balance\n * Fix exchange rates plugin\n * Network layer: refactoring and fixes\n\n# Release 2.1.1\n * patch a bug that prevents new wallet creation.\n * fix connection issue on osx binaries\n\n# Release 2.1\n * Faster startup, thanks to the following optimizations:\n   1. Transaction input/outputs are cached in the wallet file\n   2. Fast X509 certificate parser, not using pyasn1 anymore.\n   3. The Label Sync plugin only requests modified labels.\n * The 'Invoices' and 'Send' tabs have been merged.\n * Contacts are stored in a separate file, shared between wallets.\n * A Search Box is available in the GUI (Ctrl-S)\n * Payment requests have an expiration date and can be exported to\n   BIP70 files.\n * file: scheme support in BIP72 URIs: \"bitcoin:?r=file:///...\"\n * Own addresses are shown in green in the Transaction dialog.\n * Address History dialog.\n * The OpenAlias plugin was improved.\n * Various bug fixes and GUI improvements.\n * A new LabelSync backend is being used an import of the old\n   database was made but since the release came later it's\n   recommended that you do a full push when you upgrade.\n\n# Release 2.0.4 - Minor GUI improvements\n * The password dialog will ask for password again if the user enters\n   a wrong password\n * The Master Public Key dialog displays which keys belong to the\n   wallet, and which are cosigners\n * The transaction dialog will ask to save unsaved transaction\n   received from cosigner pool, when user clicks on 'Close'\n * The multisig restore dialog accepts xprv keys.\n * The network daemon must be started explicitly before using commands\n   that require a connection\n   Example:\n     electrum daemon start\n     electrum getaddressunspent <addr>\n     electrum daemon status\n     electrum daemon stop\n   If a daemon is running, the GUI will use it.\n\n# Release 2.0.3 - bugfixes and minor GUI improvements\n * Do not use daemon threads (fix #960)\n * Add a zoom button to receive tab\n * Add exchange rate conversion to receive tab\n * Use Tor's default port number in default proxy config\n\n# Release 2.0.2 - bugfixes\n * Fix transaction sweep (#1066)\n * Fix thread timing bug (#1054)\n\n# Release 2.0.1 - bugfixes\n * Fix critical bug in TREZOR address derivation: passphrases were not\n   NFKD normalized. TREZOR users who created a wallet protected by a\n   passphrase containing utf-8 characters with diacritics are\n   affected. These users will have to open their wallet with version\n   2.0 and to move their funds to a new wallet.\n * Use a file socket for the daemon (fixes network dialog issues)\n * Fix crash caused by QR scanner icon when zbar not installed.\n * Fix CosignerPool plugin\n * Label Sync plugin: Fix label sharing between multisig wallets\n\n\n# Release 2.0\n\n * Before you upgrade, make sure you have saved your wallet seed on\n   paper.\n\n * Documentation is now hosted on a wiki: http://electrum.orain.org\n\n * New seed derivation method (not compatible with BIP39). The seed\n   phrase includes a version number, that refers to the wallet\n   structure. The version number also serves as a checksum, and it\n   will prevent the import of seeds from incompatible wallets. Old\n   Electrum seeds are still supported.\n\n * New address derivation (BIP32). Standard wallets are single account\n   and use a gap limit of 20.\n\n * Support for Multisig wallets using parallel BIP32 derivations and\n   P2SH addresses (\"2 of 2\", \"2 of 3\").\n\n * Compact serialization format for unsigned or partially signed\n   transactions, that includes the BIP32 master public key and\n   derivation needed to sign inputs. Serialized transactions can be\n   sent to cosigners or to cold storage using QR codes (using Andreas\n   Schildbach's base 43 idea).\n\n * Support for BIP70 payment requests:\n   - Verification of the chain of signatures uses tlslite.\n   - In the GUI, payment requests are shown in the 'Invoices' tab.\n\n * Support for hardware wallets: TREZOR (SatoshiLabs) and Btchip (Ledger).\n\n * Two-factor authentication service by TrustedCoin. This service uses\n   \"2 of 3\" multisig wallets and Google Authenticator. Note that\n   wallets protected by this service can be deterministically restored\n   from seed, without Trustedcoin's server.\n\n * Cosigner Pool plugin: encrypted communication channel for multisig\n   wallets, to send and receive partially signed transactions.\n\n * Audio Modem plugin: send and receive transactions by sound.\n\n * OpenAlias plugin: send bitcoins to aliases verified using DNSSEC.\n\n * New 'Receive' tab in the GUI:\n   - create and manage payment requests, with QR Codes\n   - the former 'Receive' tab was renamed to 'Addresses'\n   - the former Point of Sale plugin is replaced by a resizable\n     window that pops up if you click on the QR code\n\n * The 'Send' tab in the Qt GUI supports transactions with multiple\n   outputs, and raw hexadecimal scripts.\n\n * The GUI can connect to the Electrum daemon: \"electrum -d\" will\n   start the daemon if it is not already running, and the GUI will\n   connect to it. The daemon can serve several clients. It times out\n   if no client uses if for more than 5 minutes.\n\n * The install wizard can be used to import addresses or private\n   keys. A watching-only wallet is created by entering a list of\n   addresses in the wizard dialog.\n\n * New file format: Wallets files are saved as JSON. Note that new\n   wallet files cannot be read by older versions of Electrum. Old\n   wallet files will be converted to the new format; this operation\n   may take some time, because public keys will be derived for each\n   address of your wallet.\n\n * The client accepts servers with a CA-signed SSL certificate.\n\n * ECIES encrypt/decrypt methods, available in the GUI and using\n   the command line:\n      encrypt <pubkey> <message>\n      decrypt <pubkey> <message>\n\n * The Android GUI has received various updates and it is much more\n   stable. Another script was added to Android, called Authenticator,\n   that works completely offline: it reads an unsigned transaction\n   shown as QR code, signs it and shows the result as a QR code.\n\n\n# Release 1.9.8\n\n* Electrum servers were upgraded to version 0.9. The new server stores\n  a Patrica tree of all UTXOs, an idea proposed by Alan Reiner in the\n  bitcointalk forum. This property allows the client to directly\n  request the balance of any address. The new commands are:\n     1. getaddressbalance <address>\n     2. getaddressunspent <address>\n     3. getutxoaddress <txid> <pos>\n\n* Command-line commands that require a connection to the network spawn\n  a daemon, that remains connected and handles subsequent\n  commands. The daemon terminates itself if it remains unused for more\n  than one minute. The purpose of this is to make scripting more\n  efficient. For example, a bash script using many electrum commands\n  will open only one connection.\n\n# Release 1.9.7\n* Fix for offline signing\n* Various bugfixes\n* GUI usability improvements\n* Coinbase Buyback plugin\n\n# Release 1.9.6\n* During wallet creation, do not write seed to disk until it is encrypted.\n* Confirmation dialog if the transaction fee is higher than 1mBTC.\n* bugfixes\n\n# Release 1.9.5\n\n* Coin control: select addresses to send from\n* Put addresses that have been used in a minimized section (Qt GUI)\n* Allow non ascii chars in passwords\n\n\n# Release 1.9.4\nbugfixes: offline transactions\n\n# Release 1.9.3\nbugfixes: connection problems, transactions staying unverified\n\n# Release 1.9.2\n* fix a syntax error\n\n# Release 1.9.1\n* fix regression with --offline mode\n* fix regression with --portable mode: use a dedicated directory\n\n# Release 1.9\n\n* The client connects to multiple servers in order to retrieve block headers and find the longest chain\n* SSL certificate validation (to prevent MITM)\n* Deterministic signatures (RFC 6979)\n* Menu to create/restore/open wallets\n* Create transactions with multiple outputs from CSV (comma separated values)\n* New text gui: stdio\n* Plugins are no longer tied to the qt GUI, they can reach all GUIs\n* Proxy bugs have been fixed\n\n\n# Release 1.8.1\n\n* Notification option when receiving new transactions\n* Confirm dialogue before sending large amounts\n* Alternative datafile location for non-windows systems\n* Fix offline wallet creation\n* Remove enforced tx fee\n* Tray icon improvements\n* Various bugfixes\n\n\n# Release 1.8\n\n* Menubar in classic gui\n* Updated the QR Code plugin to enable offline/online wallets to transmit unsigned/signed transactions via QR code.\n* Fixed bug where never-confirmed transactions prevented further spending\n\n\n# Release 1.7.4\n\n* Increase default fee\n* fix create and restore in command line\n* fix verify message in the gui\n\n\n# Release 1.7.3:\n\n* Classic GUI can display amounts in mBTC\n* Account selector in the classic GUI\n* Changed the way the portable flag uses without supplying a -w argument\n* Classic GUI asks users to enter their seed on wallet creation\n\n\n# Release 1.7.2:\n\n* Transactions that are in the same block are displayed in chronological order in the history.\n* The client computes transaction priority and rejects zero-fee transactions that need a fee.\n* The default fee was lowered to 200 uBTC per kb.\n* Due to an internal format change, your history may be pruned when\n  you open your wallet for the first time after upgrading to 1.7.2. If\n  this is the case, please visit a full server to restore your full\n  history. You will only need to do that once.\n\n\n# Release 1.7.1:  bugfixes.\n\n\n# Release 1.7\n\n* The Classic GUI can be extended with plugins. Developers who want to\nadd new features or third-party services to Electrum are invited to\nwrite plugins. Some previously existing and non-essential features of\nElectrum (point-of-sale mode, qrcode scanner) were removed from the\ncore and are now available as plugins.\n\n* The wallet waits for 2 confirmations before creating new\naddresses. This makes recovery from seed more robust. Note that it\nmight create unwanted gaps if you use Electrum 1.7 together with older\nversions of Electrum.\n\n* An interactive Python console replaces the 'Wall' tab. The provided\npython environment gives users access to the wallet and gui. Most\nelectrum commands are available as python function in the\nconsole. Custom scripts an be loaded with a \"run(filename)\"\ncommand. Tab-completions are available.\n\n* The location of the Electrum folder in Windows changed from\nLOCALAPPDATA to APPDATA. Discussion on this topic can be found here:\nhttps://bitcointalk.org/index.php?topic=144575.0\n\n* Private keys can be exported from within the classic GUI:\n  For a single address, use the address menu (right-click).\n  To export the keys of your entire wallet, use the settings dialog (import/export tab).\n\n* It is possible to create, sign and redeem multisig transaction using the\ncommand line interface.  This is made possible by the following new commands:\n    dumpprivkey, listunspent, createmultisig, createrawtransaction, decoderawtransaction, signrawtransaction\nThe syntax of these commands is similar to their bitcoind counterpart.\nFor an example, see Gavin's tutorial: https://gist.github.com/gavinandresen/3966071\n\n* Offline wallets now work in a way similar to Armory:\n  1. user creates an unsigned transaction using the online (watching-only) wallet.\n  2. unsigned transaction is copied to the offline computer, and signed by the offline wallet.\n  3. signed transaction is copied to the online computer, broadcasted by the online client.\n  4. All these steps can be done via the command line interface or the classic GUI.\n\n* Many command line commands have been renamed in order to make the syntax consistent with bitcoind.\n\n# Release 1.6.2\n\n== Classic GUI\n* Added new version notification\n\n# Release 1.6.1 (11-01-2013)\n\n== Core\n* It is now possible to restore a wallet from MPK (this will create a watching-only wallet)\n* A switch button allows to easily switch between Lite and Classic GUI.\n\n== Classic GUI\n* Seed and MPK help dialogs were rewritten\n* Point of Sale: requested amounts can be expressed in other currencies and are converted to bitcoin.\n\n== Lite GUI\n* The receiving button was removed in favor of a menu item to keep it consistent with the history toggle.\n\n# Release 1.6.0 (07-01-2013)\n\n== Core\n* (Feature) Add support for importing, signing and verifiying compressed keys\n* (Feature) Auto reconnect to random server on disconnect\n* (Feature) Ultimate fallback to HTTP port 80 if TCP doesn't work on any server\n* (Bug) Under rare circumstances changing password with incorrect password could damage wallet\n\n== Lite GUI\n* (Chore) Use blockchain.info for exchange rate data\n* (Feature) added currency conversion for BRL, CNY, RUB\n* (Feature) Saraha theme\n* (Feature) csv import/export for transactions including labels\n\n== Classic GUI\n* (Chore) pruning servers now called \"p\", full servers \"f\" to avoid confusion with terms\n* (Feature) Debits in history shown in red\n* (Feature) csv import/export for transactions including labels\n\n# Release 1.5.8 (02-01-2013)\n\n== Core\n* (Bug) Fix pending address balance on received coins for pruning servers\n* (Bug) Fix history command line option to show output again (regression by SPV)\n* (Chore) Add timeout to blockchain headers file download by HTTP\n* (Feature) new option: -L, --language: default language used in GUI.\n\n== Lite GUI\n* (Bug) Sending to auto-completed contacts works again\n* (Chore) Added version number to title bar\n\n== Classic GUI\n* (Feature) Language selector in options.\n\n# Release 1.5.7 (18-12-2012)\n\n== Core\n* The blockchain headers file is no longer included in the packages, it is downloaded on startup.\n* New command line option: -P or --portable, for portable wallets. With this flag, all preferences are saved to the wallet file, and the blockchain headers file is in the same directory as the wallet\n\n== Lite GUI\n* (Feature) Added the ability to export your transactions to a CSV file.\n* (Feature) Added a label dialog after sending a transaction.\n* (Feature) Reworked receiving addresses; instead of a random selection from one of your receiving addresses a new widget will show listing unused addresses.\n* (Chore)   Removed server selection. With all the new server options a simple menu item does not suffice anymore.\n"

    "content": "# Qml GUI\n\nThe Qml GUI is used with Electrum on Android devices, since Electrum 4.4.\nTo generate an APK file, follow these instructions.\n\n(note: older versions of Electrum for Android used the \"kivy\" GUI)\n\n## Android binary with Docker\n\n✓ _These binaries should be reproducible, meaning you should be able to generate\n   binaries that match the official releases._\n\n- _Minimum supported target system (i.e. what end-users need): Android 6.0 (API 23)_\n\nThis assumes an Ubuntu (x86_64) host, but it should not be too hard to adapt to another\nsimilar system.\n\n1. Install Docker\n\n    See [`contrib/docker_notes.md`](../docker_notes.md).\n\n    (worth reading even if you already have docker)\n\n2. Build binaries\n\n    The build script takes a few arguments. To see syntax, run it without providing any:\n    ```\n    $ ./build.sh\n    ```\n    For development, consider e.g. `$ ./build.sh qml arm64-v8a debug`\n\n    If you want reproducibility, try instead e.g.:\n    ```\n    $ ELECBUILD_COMMIT=HEAD ./build.sh qml all release-unsigned\n    ```\n\n3. The generated binary is in `./dist`.\n\n\n## Verifying reproducibility and comparing against official binary\n\nEvery user can verify that the official binary was created from the source code in this\nrepository.\n\n1. Build your own binary as described above.\n   Make sure you don't build in `debug` mode,\n   instead use either of `release` or `release-unsigned`.\n   If you build in `release` mode, the apk will be signed, which requires a keystore\n   that you need to create manually (see source of `make_apk.sh` for an example).\n2. Note that the binaries are not going to be byte-for-byte identical, as the official\n   release is signed by a keystore that only the project maintainers have.\n   You can use the `apkdiff.py` python script (written by the Signal developers) to compare\n   the two binaries.\n    ```\n    $ python3 contrib/android/apkdiff.py Electrum_apk_that_you_built.apk Electrum_apk_official_release.apk\n    ```\n   This should output `APKs match!`.\n\n\n## FAQ\n\n### I changed something but I don't see any differences on the phone. What did I do wrong?\nYou probably need to clear the cache: `rm -rf .buildozer/android/platform/build-*/{build,dists}`\n\n\n### How do I deploy on connected phone for quick testing?\nAssuming `adb` is installed:\n```\n$ adb -d install -r dist/Electrum-*-arm64-v8a-debug.apk\n$ adb shell monkey -p org.electrum.electrum 1\n```\nNote `adb install` can take a `--user {userId}` option to install the app for a specific profile.\nWithout that, the default is to install to *all* profiles.\n\n\n### How do I get an interactive shell inside docker?\n```\n$ docker run -it --rm \\\n    -v $PWD:/home/user/wspace/electrum \\\n    -v $PWD/.buildozer/.gradle:/home/user/.gradle \\\n    --workdir /home/user/wspace/electrum \\\n    electrum-android-builder-img\n```\n\n\n### How do I get more verbose logs for the build?\nSee `log_level` in `buildozer.spec`\n\n\n### How can I see logs at runtime?\nThis should work OK for most scenarios:\n```\nadb logcat | grep python\n```\nBetter `grep` but fragile because of `cut`:\n```\nadb logcat | grep -F \"`adb shell ps | grep org.electrum.electrum | cut -c14-19`\"\n```\n\n\n### The Qml GUI can be run directly on Linux Desktop. How?\nInstall requirements:\n```\npython3 -m pip install \".[qml_gui]\"\n```\n\nRun electrum with the `-g` switch: `electrum -g qml`\n\nNotes:\n\n- pyqt ~6.4 would work best, as the gui has not yet been adapted to styling changes in 6.5\n- However, pyqt6 as distributed on PyPI does not include a required module (PyQt6.QtQml) until 6.5\n- Installing these deps from your OS package manager should also work,\n  except many don't distribute pyqt6 yet.\n  For pyqt5 on debian-based distros, this used to look like this:\n  ```\n  sudo apt-get install python3-pyqt5 python3-pyqt5.qtquick python3-pyqt5.qtmultimedia\n  sudo apt-get install python3-pil\n  sudo apt-get install qml-module-qtquick-controls2 qml-module-qtquick-layouts \\\n      qml-module-qtquick-window2 qml-module-qtmultimedia \\\n      libqt5multimedia5-plugins qml-module-qt-labs-folderlistmodel\n  ```\n\n\n### debug vs release build\nIf you just follow the instructions above, you will build the apk\nin debug mode. The most notable difference is that the apk will be\nsigned using a debug keystore. If you are planning to upload\nwhat you build to e.g. the Play Store, you should create your own\nkeystore, back it up safely, and run `./build.sh` in `release` mode.\n\nSee e.g. [kivy wiki](https://github.com/kivy/kivy/wiki/Creating-a-Release-APK)\nand [android dev docs](https://developer.android.com/studio/build/building-cmdline#sign_cmdline).\n\n### Access datadir on Android from desktop (e.g. to copy wallet file)\nNote that this only works for debug builds! Otherwise the security model\nof Android does not let you access the internal storage of an app without root.\n(See [this](https://stackoverflow.com/q/9017073))\nTo pull a file:\n```\n$ adb shell\nadb$ run-as org.electrum.electrum ls /data/data/org.electrum.electrum/files/data\nadb$ exit\n$ adb exec-out run-as org.electrum.electrum cat /data/data/org.electrum.electrum/files/data/wallets/my_wallet > my_wallet\n```\nTo push a file:\n```\n$ adb push ~/wspace/tmp/my_wallet /data/local/tmp\n$ adb shell\nadb$ ls -la /data/local/tmp\nadb$ run-as org.electrum.testnet.electrum cp /data/local/tmp/my_wallet /data/data/org.electrum.testnet.electrum/files/data/testnet/wallets/\nadb$ run-as org.electrum.testnet.electrum chmod -R 700 /data/data/org.electrum.testnet.electrum/files/data/testnet/wallets\nadb$ run-as org.electrum.testnet.electrum chmod -R u-x,u+X /data/data/org.electrum.testnet.electrum/files/data/testnet/wallets\nadb$ rm /data/local/tmp/my_wallet\n```\n\nOr use Android Studio: \"Device File Explorer\", which can download/upload data directly from device (via adb).\n\n#### Device with multiple user profiles\n\nThere are further complications if using an Android device\n[with multiple user profiles](https://source.android.com/docs/devices/admin/multi-user-testing)\n(typical for GrapheneOS/etc).\n\nRun `$ adb shell pm list users` to get a list of all existing users, and take note of the user ids.\n\nInstead of `/data/data/{app.path}`, private app data is stored at `/data/user/{userId}/{app.path}`.\n\nFurther, instead of `adb$ run-as org.electrum.electrum`,\nyou need `adb$ run-as org.electrum.electrum --user {userId}`.\n\n### How to investigate diff between binaries if reproducibility fails?\n```\ncd dist/\nunzip Electrum-*.apk1 -d apk1\nmkdir apk1/assets/private_mp3/\ntar -xzvf apk1/assets/private.tar --directory apk1/assets/private_mp3/\nmkdir apk1/lib/_libpybundle/\ntar -xzvf apk1/lib/*/libpybundle.so --directory apk1/lib/_libpybundle/\n\nunzip Electrum-*.apk2 -d apk2\nmkdir apk2/assets/private_mp3/\ntar -xzvf apk2/assets/private.tar --directory apk2/assets/private_mp3/\nmkdir apk2/lib/_libpybundle/\ntar -xzvf apk2/lib/*/libpybundle.so --directory apk2/lib/_libpybundle/\n\nsudo chown --recursive \"$(id -u -n)\":\"$(id -u -n)\" apk1/ apk2/\nchmod -R +Xr  apk1/ apk2/\n\nunzip apk1/lib/_libpybundle/_python_bundle/stdlib.zip -d apk1/lib/_libpybundle/_python_bundle/stdlib\nunzip apk2/lib/_libpybundle/_python_bundle/stdlib.zip -d apk2/lib/_libpybundle/_python_bundle/stdlib\n\nsudo chown --recursive \"$(id -u -n)\":\"$(id -u -n)\" apk1/ apk2/\nchmod -R +Xr  apk1/ apk2/\n$(cd apk1; find -type f -exec sha256sum '{}' \\; > ./../sha256sum1)\n$(cd apk2; find -type f -exec sha256sum '{}' \\; > ./../sha256sum2)\ndiff sha256sum1 sha256sum2 > d\ncat d\n```\n\n### How to install apks built by the CI on my phone?\n\nThe CI (Cirrus) builds apks on most git commits.\nSee e.g. [here](https://github.com/spesmilo/electrum/runs/9272252577).\nThe task name should start with \"Android build\".\nClick \"View more details on Cirrus CI\" to get to cirrus' website, and search for \"Artifacts\".\nThe apk is built in `debug` mode, and is signed using an ephemeral RSA key.\n\nFor tech demo purposes, you can directly install this apk on your phone.\nHowever, if you already have electrum installed on your phone, Android's TOFU signing model\nwill not let you upgrade that to the CI apk due to mismatching signing keys. As the CI key\nis ephemeral, it is not even possible to upgrade from an older CI apk to a newer CI apk.\n\nHowever, it is possible to resign the apk manually with one's own key, using\ne.g. [`apksigner`](https://developer.android.com/studio/command-line/apksigner),\nmutating the apk in place, after which it should be possible to upgrade:\n```\napksigner sign --ks ~/wspace/electrum/contrib/android/android_debug.keystore Electrum-*-arm64-v8a-debug.apk\n```\n"

If you are packaging for a Linux distro,\n  you probably want to compile the .mo locale files yourself (see `contrib/locale/build_locale.sh`).\n- the normal tarball includes generated `*_pb2.py` files. These are created\n  using `protobuf-compiler` from `.proto` files (see `contrib/generate_payreqpb2.sh`)\n"

The generated binaries are in `./contrib/build-wine/dist`.\n\n\n\n## Code Signing\n\nElectrum Windows builds are signed with a Microsoft Authenticode™ code signing\ncertificate in addition to the GPG-based signatures.\n\nThe advantage of using Authenticode is that Electrum users won't receive a\nWindows SmartScreen warning when starting it.\n\nThe release signing procedure involves a signer (the holder of the\ncertificate/key) and one or multiple trusted verifiers:\n\n\n| Signer                                                    | Verifier                             |\n|-----------------------------------------------------------|--------------------------------------|\n| Build .exe files using `make_win.sh`                      |                                      |\n| Sign .exe with `./sign.sh`                                |                                      |\n| Upload signed files to download server                    |                                      |\n|                                                           | Build .exe files using `make_win.sh` |\n|                                                           | Compare files using `unsign.sh`      |\n|                                                           | Sign .exe file using `gpg -b`        |\n\n| Signer and verifiers:                                                                            |\n|--------------------------------------------------------------------------------------------------|\n| Upload signatures to 'electrum-signatures' repo, as `$version/$filename.$builder.asc`            |\n\n\n\n## Verify Integrity of signed binary\n\nEvery user can verify that the official binary was created from the source code in this\nrepository. To do so, the Authenticode signature needs to be stripped since the signature\nis not reproducible.\n\nThis procedure removes the differences between the signed and unsigned binary:\n\n1. Remove the signature from the signed binary using osslsigncode or signtool.\n2. Set the COFF image checksum for the signed binary to 0x0. This is necessary\n   because pyinstaller doesn't generate a checksum.\n3. Append null bytes to the _unsigned_ binary until the byte count is a multiple\n   of 8.\n\nThe script `unsign.sh` performs these steps.\n\n## FAQ\n\n### How to investigate diff between binaries if reproducibility fails?\n`pyi-archive_viewer` is needed, for that run `$ pip install pyinstaller`.\nAs a first pass overview, run:\n```\npyi-archive_viewer -l electrum-*.exe1 > f1\npyi-archive_viewer -l electrum-*.exe2 > f2\ndiff f1 f2 > d\ncat d\n```\nThen investigate manually:\n```\n$ pyi-archive_viewer electrum-*.exe1\n? help\n```\n"

Install `libsecp256k1`\n\n[comment]: # (technically the dll should be put into site-packages/electrum_ecc/,\nbut putting it into electrum/ also works because of the `os.add_dll_directory` call in\nelectrum/__init__.py)\n\n[libsecp256k1](https://github.com/bitcoin-core/secp256k1) is a required dependency.\nThis is a C library, which you need to compile yourself.\nElectrum needs a dll, named `libsecp256k1-0.dll` (or newer `libsecp256k1-*.dll`),\nplaced into the inner `electrum/` folder.\n\nFor Unix-like systems, the (`contrib/make_libsecp256k1.sh`) script does this for you,\nhowever it does not work on Windows.\nIf you have access to a Linux machine (e.g. VM) or perhaps even using\nWSL (Windows Subsystem for Linux), you can cross-compile from there to Windows,\nand build this dll:\n```\n$ GCC_TRIPLET_HOST=\"x86_64-w64-mingw32\" ./contrib/make_libsecp256k1.sh\n```\n\nAlternatively, MSYS2 and MinGW-w64 can be used directly on Windows, as follows.\n\n- download and install [MSYS2](https://www.msys2.org/)\n- run MSYS2\n- inside the MSYS2 shell:\n  ```\n  $ pacman -Syu\n  $ pacman -S --needed git base-devel mingw-w64-x86_64-toolchain mingw-w64-x86_64-autotools\n  $ export PATH=\"$PATH:/mingw64/bin\"\n  ```\n  `cd` into the git clone, e.g. `C:\\wspace\\electrum` (auto-mounted at `/c/wspace/electrum`)\n  ```\n  $ cd /c/wspace/electrum\n  $ GCC_TRIPLET_HOST=\"x86_64-w64-mingw32\" ./contrib/make_libsecp256k1.sh\n  ```\n\n(note: this is a bit cumbersome, see [issue #5976](https://github.com/spesmilo/electrum/issues/5976)\nfor discussion)\n\n### 3. Run electrum:\n\n```\n> python3 ./run_electrum\n```\n\n"

    "content": "# Using the build scripts\n\nMost of our build scripts are docker-based.\n(All, except the macOS build, which is a separate beast and always has to be special-cased\nat the cost of significant maintenance burden...)\n\nTypically, the build flow is:\n\n- build a docker image, based on debian\n  - the apt sources mirror used is `snapshot.debian.org`\n    - (except for the source tarball build, which is simple enough not to need this)\n    - this helps with historical reproducibility\n    - note that `snapshot.debian.org` is often slow and sometimes keeps timing out :/\n      (see #8496)\n      - a potential alternative would be `snapshot.notset.fr`, but that mirror is missing\n        e.g. `binary-i386`, which is needed for the wine/windows build.\n    - if you are just trying to build for yourself and don't need reproducibility,\n      you can just switch back to the default debian apt sources mirror.\n  - docker caches the build (locally), and so this step only needs to be rerun\n    if we update the Dockerfile. This caching happens automatically and by default.\n    - you can disable the caching by setting envvar `ELECBUILD_NOCACHE=1`. See below.\n- create a docker container from the image, and build the final binary inside the container\n\n\n## Notes about using Docker\n\n- To install Docker:\n\n    This assumes an Ubuntu (x86_64) host, but it should not be too hard to adapt to another similar system.\n\n    ```\n    $ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -\n    $ sudo add-apt-repository \"deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable\"\n    $ sudo apt-get update\n    $ sudo apt-get install -y docker-ce\n    ```\n\n- To communicate with the docker daemon, the build scripts either need to be called via sudo,\n  or the unix user on the host system (e.g. the user you run as) needs to be\n  part of the `docker` group. i.e.:\n  ```\n  $ sudo usermod -aG docker ${USER}\n  ```\n  (and then reboot or similar for it to take effect)\n\n\n## Environment variables\n\n- `ELECBUILD_COMMIT`\n\n    When unset or empty, we build directly from the local git clone. These builds\n    are *not* reproducible.\n\n    When non-empty, it should be set to a git ref. We will create a fresh git clone\n    checked out at that reference in `/tmp/electrum_build/`, and build there.\n\n- `ELECBUILD_NOCACHE=1`\n\n    A non-empty value forces a rebuild of the docker image.\n\n    Before we started using `snapshot.debian.org` for apt sources,\n    setting this was necessary to properly test historical reproducibility.\n    (we were version-pinning packages installed using `apt`, but it was not realistic to\n     version-pin all transitive dependencies, and sometimes an update of those resulted in\n     changes to our binary builds)\n\n    I think setting this is no longer necessary for building reproducibly.\n\n"

    "content": "Building macOS binaries\n=======================\n\n✓ _This binary should be reproducible, meaning you should be able to generate\n   binaries that match the official releases._\n\n- _Minimum supported target system (i.e. what end-users need): macOS 11_\n\nThis guide explains how to build Electrum binaries for macOS systems.\n\n\n## Building the binary\n\nThis needs to be done on a system running macOS or OS X.\n\nThe script is only tested on Intel-based (x86_64) Macs, and the binary built\ntargets `x86_64` currently.\n\nNotes about compatibility with different macOS versions:\n- In general the binary is not guaranteed to run on an older version of macOS\n  than what the build machine has. This is due to bundling the compiled Python into\n  the [PyInstaller binary](https://github.com/pyinstaller/pyinstaller/issues/1191).\n- The [bundled version of Qt](https://github.com/spesmilo/electrum/issues/3685) also\n  imposes a minimum supported macOS version.\n- If you want to build binaries that conform to the macOS \"Gatekeeper\", so as to\n  minimise the warnings users get, the binaries need to be codesigned with a\n  certificate issued by Apple, and starting with macOS 10.15 (targets) the binaries also\n  need to be notarized by Apple's central server. To be able to build\n  binaries that Apple will notarize (due to the requirements on the binaries themselves,\n  e.g. hardened runtime) the build machine needs at least macOS 10.14.\n  See [#6128](https://github.com/spesmilo/electrum/issues/6128).\n  - There are two tools that can be used to notarize a binary, both part of Xcode:\n    the old `altool` and the newer `notarytool`. `altool`\n    [was deprecated](https://developer.apple.com/news/?id=y5mjxqmn) by Apple.\n    `notarytool` requires Xcode 13+, and that in turn requires macOS 11.3+.\n\nWe currently build the release binaries on macOS 11.7.10, and these seem to run on\n11 or newer.\n\n\n#### Notes about reproducibility\n\n- We recommend creating a VM with a macOS guest, e.g. using VirtualBox,\n  and building there.\n- The guest should run macOS 11.7.10 (that specific version).\n- The unix username should be `vagrant`, and `electrum` should be cloned directly\n  to the user's home dir: `/Users/vagrant/electrum`.\n- Builders need to use the same version of Xcode; and note that\n  full Xcode and Xcode commandline tools differ!\n  We use the Xcode CLI tools as installed by brew. (version 13.2)\n\n  Sanity checks:\n    ```\n    $ sw_vers\n    ProductName:\tmacOS\n    ProductVersion:\t11.7.10\n    BuildVersion:\t20G1427\n    $ xcode-select -p\n    /Library/Developer/CommandLineTools\n    $ xcrun --show-sdk-path\n    /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk\n    $ pkgutil --pkg-info=com.apple.pkg.CLTools_Executables\n    package-id: com.apple.pkg.CLTools_Executables\n    version: 13.2.0.0.1.1638488800\n    volume: /\n    location: /\n    install-time: XXXXXXXXXX\n    groups: com.apple.FindSystemFiles.pkg-group\n    $ gcc --version\n    Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1\n    Apple clang version 13.0.0 (clang-1300.0.29.30)\n    Target: x86_64-apple-darwin20.6.0\n    Thread model: posix\n    InstalledDir: /Library/Developer/CommandLineTools/usr/bin\n    ```\n- Installing extraneous brew packages can result in build differences.\n  For example, pyinstaller seems to pick up and bundle brew-installed `libffi`.\n  So having a dedicated \"electrum binary builder macOS VM\" is recommended.\n- Make sure that you are building from a fresh clone of electrum\n  (or run e.g. `git clean -ffxd` to rm all local changes).\n\n\n#### 1. Install brew\n\nInstall [`brew`](https://brew.sh/).\n\nLet brew install the Xcode CLI tools.\n\n\n#### 2. Build Electrum\n\n    cd electrum\n    ./contrib/osx/make_osx.sh\n\nThis creates both a folder named Electrum.app and the .dmg file (both unsigned).\n\n##### 2.1. For release binaries, here be dragons\n\nIf you want the binaries codesigned for macOS and notarised by Apple's central server,\nalso run the `sign_osx.sh` script:\n\n    CODESIGN_CERT=\"Developer ID Application: Electrum Technologies GmbH (L6P37P7P56)\" \\\n    APPLE_TEAM_ID=\"L6P37P7P56\" \\\n    APPLE_ID_USER=\"me@email.com\" \\\n    APPLE_ID_PASSWORD=\"1234\" \\\n    ./contrib/osx/sign_osx.sh\n\n(note: `APPLE_ID_PASSWORD` is an app-specific password, *not* the account password)\n\n\n## Verifying reproducibility and comparing against official binary\n\nEvery user can verify that the official binary was created from the source code in this\nrepository.\n\n1. Build your own binary as described above.\n2. Use the provided `compare_dmg` script to compare the binary you built with\n   the official release binary.\n    ```\n    $ ./contrib/osx/compare_dmg dist/electrum-*.dmg electrum_dmg_official_release.dmg\n    ```\n   The `compare_dmg` script is mostly only needed as the official release binary is\n   codesigned and notarized. Otherwise, the built `.app` bundles should be byte-identical.\n   (Note that we are using `hdutil` to create the `.dmg`, and its output is not\n   deterministic, but we cannot compare the `.dmg` files directly anyway as they contain\n   codesigned files)\n\n\n## FAQ\n\n### What is macOS \"codesigning\" and \"notarization\"?\n\nCodesigning is the macOS OS-native signing of executables/shared-libs,\nthat needs to be done using an ~x509-like certificate that chains back to Apple's root CA.\nOnce a developer certificate is obtained from Apple, it can be used to codesign locally\non a dev machine.\n\nNotarization is a further step usually done after, which entails uploading a distributable\nover the network to the Apple mothership central server, which runs some arbitrary checks on it,\nand if it finds the file ok, the central server gives the dev a notarization staple.\nThis staple can then be optionally \"attached\" to the distributable, mutating it, which we do.\n(If the staple is not attached, enduser machines request it from the mothership at runtime.)\n\nBoth these steps should be done during the build process.\n\n### What is \"codesigned\" and/or \"notarized\", re the official release?\n\n- `make_osx.sh` builds a `.app`, which is unsigned/unnotarized\n  - at this point, this `.app` is ~\"byte-for-byte\" reproducible\n    - this is the sanity-check hash printed at the end of `make_osx.sh`\n  - `make_osx.sh` creates a `.dmg` from the `.app`\n    - this `.dmg` is not used for the official release at all, but used as the basis of\n      testing reproducibility using the `compare_dmg` script\n- `sign_osx.sh` codesigns the `.app` (mutating it)\n- `sign_osx.sh` -> `notarize_app.sh` notarizes the `.app` (mutating it)\n- `sign_osx.sh` creates a `.dmg` from the `.app`\n- `sign_osx.sh` codesigns the `.dmg` (mutating it)\n  - this `.dmg` becomes the official release distributable\n\nThat is, the official release `.dmg` is codesigned but NOT notarized.\nIt contains a `.app`, which is codesigned AND notarized.\n\n### How to check if a file is codesigned?\n\nBoth the `.dmg` and the contained `.app` are codesigned:\n```\n$ codesign --verify --deep --strict --verbose=2 $HOME/Desktop/electrum-4.5.8.dmg && echo \"signed\"\n/Users/vagrant/Desktop/electrum-4.5.8.dmg: valid on disk\n/Users/vagrant/Desktop/electrum-4.5.8.dmg: satisfies its Designated Requirement\nsigned\n```\n```\n$ codesign --verify --deep --strict --verbose=1 $HOME/Desktop/Electrum-4.5.8.app && echo \"signed\"\n/Users/vagrant/Desktop/Electrum-4.5.8.app: valid on disk\n/Users/vagrant/Desktop/Electrum-4.5.8.app: satisfies its Designated Requirement\nsigned\n```\n\nAlso see `$ codesign -dvvv $HOME/Desktop/electrum-4.5.8.dmg`\n\n### How to check if a file is notarized?\n\nThe outer `.dmg` is NOT notarized, but the inner `.app` is notarized:\n```\n$ spctl -a -vvv -t install $HOME/Desktop/electrum-4.5.8.dmg\n/Users/vagrant/Desktop/electrum-4.5.8.dmg: rejected\nsource=Unnotarized Developer ID\norigin=Developer ID Application: Electrum Technologies GmbH (L6P37P7P56)\n```\n```\n$ spctl -a -vvv -t install $HOME/Desktop/Electrum-4.5.8.app\n/Users/vagrant/Desktop/Electrum-4.5.8.app: accepted\nsource=Notarized Developer ID\norigin=Developer ID Application: Electrum Technologies GmbH (L6P37P7P56)\n```\n\n### How to simulate the signing procedure?\n\nIt is possible to run `sign_osx.sh` using a self-signed certificate to test the\nsigning procedure without using a production certificate.\n\nNote that the notarization process will be skipped as it is not possible to notarize\nan executable with Apple using a self-signed certificate.\n\n#### To generate a self-signed certificate, inside your **MacOS VM**:\n1. Open the `Keychain Access` application.\n2. In the menubar go to `Keychain Access` > `Certificate Assistant` > `Create a Certificate...`\n3. Set a name (e.g. `signing_dummy`)\n4. Change `Certificate Type` to *'Code Signing'*\n5. Click `Create` and `Continue`.\n\nYou now have a self-signed certificate `signing_dummy` added to your `login` keychain.\n\n#### To sign the executables with the self-signed certificate:\n\nAssuming you have the two unsigned outputs of `make_osx.sh` inside `~/electrum/dist`\n(e.g. `Electrum.app` and `electrum-4.5.4-1368-gc8db684cc-unsigned.dmg`).\n\nIn `~/electrum` run:\n\n`$ CODESIGN_CERT=\"signing_dummy\" ./contrib/osx/sign_osx.sh`\n\nAfter `sign_osx.sh` finished, you will have a new `*.dmg` inside `electrum/dist`\n(without the `-unsigned` postfix) which is signed with your certificate.\n\n#### To compare the unsigned executable with the self-signed executable:\n\nRunning `compare_dmg` with `IS_NOTARIZED=false` should succeed:\n\n`$ IS_NOTARIZED=false ./electrum/contrib/osx/compare_dmg <unsigned executable> <self-signed executable>`"

HISTORY OF THE SOFTWARE\n==========================\n\nPython was created in the early 1990s by Guido van Rossum at Stichting\nMathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands\nas a successor of a language called ABC.  Guido remains Python's\nprincipal author, although it includes many contributions from others.\n\nIn 1995, Guido continued his work on Python at the Corporation for\nNational Research Initiatives (CNRI, see http://www.cnri.reston.va.us)\nin Reston, Virginia where he released several versions of the\nsoftware.\n\nIn May 2000, Guido and the Python core development team moved to\nBeOpen.com to form the BeOpen PythonLabs team.  In October of the same\nyear, the PythonLabs team moved to Digital Creations, which became\nZope Corporation.  In 2001, the Python Software Foundation (PSF, see\nhttps://www.python.org/psf/) was formed, a non-profit organization\ncreated specifically to own Python-related Intellectual Property.\nZope Corporation was a sponsoring member of the PSF.\n\nAll Python releases are Open Source (see http://www.opensource.org for\nthe Open Source Definition).  Historically, most, but not all, Python\nreleases have also been GPL-compatible; the table below summarizes\nthe various releases.\n\n    Release         Derived     Year        Owner       GPL-\n                    from                                compatible?

All Python licenses, unlike the GPL, let you distribute\n    a modified version without making your changes open source.  The\n    GPL-compatible licenses make it possible to combine Python with\n    other software that is released under the GPL; the others don't.\n\n(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,\n    because its license has a choice of law clause.  According to\n    CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1\n    is \"not incompatible\" with the GPL.\n\nThanks to the many outside volunteers who have worked under Guido's\ndirection to make these releases possible.\n\n\nB.

If only periods, then these are compared\n#    left-to-right to determine an ordering.\n# 2) sequences of letters are part of the tuple for comparison and are\n#    compared lexicographically\n# 3) recognize the numeric components may have leading zeroes\n#\n# The LooseVersion class below implements these rules: a version number\n# string is split up into a tuple of integer and string components, and\n# comparison is a simple tuple comparison.  This means that version\n# numbers behave in a predictable and obvious way, but a way that might\n# not necessarily be how people *want* version numbers to behave.  There\n# wouldn't be a problem if people could stick to purely numeric version\n# numbers: just split on period and compare the numbers as tuples.\n# However, people insist on putting letters into their version numbers;\n# the most common purpose seems to be:\n#   - indicating a \"pre-release\" version\n#     ('alpha', 'beta', 'a', 'b', 'pre', 'p')\n#   - indicating a post-release patch ('p', 'pl', 'patch')\n# but of course this can't cover all version number schemes, and there's\n# no way to know what a programmer means without asking him.\n#\n# The problem is what to do with letters (and other non-numeric\n# characters) in a version number.  The current implementation does the\n# obvious and predictable thing: keep them as strings and compare\n# lexically within a tuple comparison.  This has the desired effect if\n# an appended letter sequence implies something \"post-release\":\n# eg. \"0.99\" < \"0.99pl14\" < \"1.0\", and \"5.001\" < \"5.001m\" < \"5.002\".\n#\n# However, if letters in a version number imply a pre-release version,\n# the \"obvious\" thing isn't correct.  Eg. you would expect that\n# \"1.5.1\" < \"1.5.2a2\" < \"1.5.2\", but under the tuple/lexical comparison\n# implemented here, this just isn't so.\n#\n# Two possible solutions come to mind.  The first is to tie the\n# comparison algorithm to a particular set of semantic rules, as has\n# been done in the StrictVersion class above.  This works great as long\n# as everyone can go along with bondage and discipline.  Hopefully a\n# (large) subset of Python module programmers will agree that the\n# particular flavour of bondage and discipline provided by StrictVersion\n# provides enough benefit to be worth using, and will submit their\n# version numbering scheme to its domination.  The free-thinking\n# anarchists in the lot will never give in, though, and something needs\n# to be done to accommodate them.\n#\n# Perhaps a \"moderately strict\" version class could be implemented that\n# lets almost anything slide (syntactically), and makes some heuristic\n# assumptions about non-digits in version number strings.  This could\n# sink into special-case-hell, though; if I was as talented and\n# idiosyncratic as Larry Wall, I'd go ahead and implement a class that\n# somehow knows that \"1.2.1\" < \"1.2.2a2\" < \"1.2.2\" < \"1.2.2pl3\", and is\n# just as happy dealing with things like \"2g6\" and \"1.13++\".  I don't\n# think I'm smart enough to do it right though.\n#\n# In any case, I've coded the test suite for this module (see\n# ../test/test_version.py) specifically to fail on things like comparing\n# \"1.2a2\" and \"1.2\".  That's not because the *code* is doing anything\n# wrong, it's because the simple, obvious design doesn't match my\n# complicated, hairy expectations for real-world version numbers.  It\n# would be a snap to fix the test suite to say, \"Yep, LooseVersion does\n# the Right Thing\" (ie. the code matches the conception).  But I'd rather\n# have a conception that matches common notions about version numbers.\n\nclass LooseVersion (Version):\n\n    \"\"\"Version numbering for anarchists and software realists.\n    Implements the standard interface for version number classes as\n    described above.

Only child processes plus normal permissions.\n#      2 - Admin-only attach. Only executables with CAP_SYS_PTRACE.\n#      3 - No attach. No process may call ptrace at all. Irrevocable.\n#    # Note: The default value of kernel.yama.ptrace_scope is distro-specific.\n#    #       See `$ cat /proc/sys/kernel/yama/ptrace_scope`.\n#    #       - ubuntu 22.04 sets it to 1 (see /etc/sysctl.d/10-ptrace.conf),\n#    #       - debian 12 sets it to 0\n#    #       - manjaro sets it to 1\n# 2.

A client communicates over a hardware\n    channel with the device.\n\n    In addition to tracking device HID IDs, the device manager tracks\n    hardware wallets and manages wallet pairing.  A HID ID may be\n    paired with a wallet when it is confirmed that the hardware device\n    matches the wallet, i.e. they have the same master public key.  A\n    HID ID can be unpaired if e.g. it is wiped.\n\n    Because of hotplugging, a wallet must request its client\n    dynamically each time it is required, rather than caching it\n    itself.\n\n    The device manager is shared across plugins, so just one place\n    does hardware scans when needed.  By tracking HID IDs, if a device\n    is plugged into a different port the wallet is automatically\n    re-paired.\n\n    Wallets are informed on connect / disconnect events.

    "content": "Plugin rules:\n\n * The plugin system of Electrum is designed to allow the development\n   of new features without increasing the core code of Electrum.\n\n * Electrum is written in pure python. if you want to add a feature\n   that requires non-python libraries, then it must be submitted as a\n   plugin. If the feature you want to add requires communication with\n   a remote server (not an Electrum server), then it should be a\n   plugin as well. If the feature you want to add introduces new\n   dependencies in the code, then it should probably be a plugin.\n\n * We expect plugin developers to maintain their plugin code. However,\n   once a plugin is merged in Electrum, we will have to maintain it\n   too, because changes in the Electrum code often require updates in\n   the plugin code. Therefore, plugins have to be easy to maintain. If\n   we believe that a plugin will create too much maintenance work in\n   the future, it will be rejected.\n\n * Plugins should be compatible with Electrum's conventions. If your\n   plugin does not fit with Electrum's architecture, or if we believe\n   that it will create too much maintenance work, it will not be\n   accepted. In particular, do not duplicate existing Electrum code in\n   your plugin.\n\n * We may decide to remove a plugin after it has been merged in\n   Electrum. For this reason, a plugin must be easily removable,\n   without putting at risk the user's bitcoins. If we feel that a\n   plugin cannot be removed without threatening users who rely on it,\n   we will not merge it.\n\n"

Leverages all\nthe good work that's been done by the Electrum team to support\nhardware wallets.\n\n## Background\n\nThe Coldcard has a larger screen (128x64) and a number pad. For\nthis reason, all PIN code entry is done directly on the device.\nColdcard does not appear on the USB bus until unlocked with appropriate\nPIN. Initial setup, and seed generation must be done offline.\n\nColdcard uses the standard for unsigned transactions:\n\nPSBT = Partially Signed Bitcoin Transaction = BIP174\n\nThe Coldcard can be used 100% offline: it can generate a skeleton\nElectrum wallet and save it to MicroSD card. Transport that file\nto Electrum and it will fetch history, blockchain details and then\noperate in \"unpaired\" mode.\n\nSpending transactions can be saved to MicroSD using by exporting them\nfrom transaction preview dialog (when this plugin is\nowner of the wallet). That PSBT is then signed on the Coldcard\n(again using MicroSD both ways). The result is a ready-to-transmit\nbitcoin transaction, which can be transmitted using Tools > Load\nTransaction > From File in Electrum or really any tool.\n\n<https://coldcardwallet.com>\n\n## TODO Items\n\n- No effort yet to support translations or languages other than English, sorry.\n- We support multisig hardware wallets based on PSBT where each participant\n  is using different devices/systems for signing.\n\n### Ctags\n\n- I find this command useful (at top level) ... but I'm a VIM user.\n\n    ctags -f .tags electrum `find . -name ENV -prune -o -name \\*.py`\n\n"

    "content": "Timelock Recovery is a mechanism which, in case of a catastrophic event\n(death or loss of your master key), can send your Bitcoin to a secondary wallet of your choice\nwithin a time-window (i.e. 90 days).\n<br />\nDuring that time-window, you can see that the Timelock Recovery mechanism has been triggered (a\ntransaction from your wallet to itself is created on the Bitcoin blockchain), and if this\nhas happened against your will, you can use your master key to cancel the process (by moving\nthe funds elsewhere before the time-window expires).\n<br />\nThe implementation of Timelock Recovery is done with two transactions that are signed in advance,\nbut broadcast only when needed:\n<ol>\n    <li>\n        An <i>Alert Transaction</i> which sends the funds from the wallet to itself (consolidating the UTXOs).\n    </li>\n    <li>\n        A <i>Recovery Transaction</i> which sends the funds to a secondary wallet of your choice and can\n        be added to the blockchain only X days after the <i>Alert Transaction</i> has been broadcast (and mined).\n    </li>\n</ol>\nOptionally, this extension will also let you sign-in-advance a <i>Cancellation Transaction</i> which can be\nused to cancel the Timelock Recovery process, by broadcasting it before the time-window expires.\nIf the <i>Alert Transaction</i> has been broadcast, the Cancellation Transaction will send the funds again to\nthe same wallet, which would invalidate the <i>Recovery Transaction</i> (technically: the <i>Recovery Transaction</i>\nwill be seen as a transaction that is trying to spend a UTXO that has already been spent).\n<br />\nTimelock Recovery plans do not require any involvement of a third party.\nHowever, two precautions should be taken:\n<ol>\n    <li>\n        Due to the way Bitcoin transactions and UTXOs work, spending funds from the wallet might break\n        the entire Timelock Recovery plan.\n    </li>\n    <li>\n        Adding more funds to the wallet will not be covered by the Timelock Recovery plan.\n    </li>\n</ol>\n<br />\nTherefore it is highly recommended not to use the wallet for any purpose after creating a\nTimelock Recovery plan (other than long-term storage).\nInstead, for daily purposes use a separate wallet (with a seed in a place that\nyour loved ones could easily find) and only after accumulating enough funds relevant for long-term\nstorage, move them to a new highly secured wallet (i.e. with a long passphrase that only you memorize) for\nwhich you create a new Timelock Recovery plan (back to the daily-purpose wallet or to your inheritors' wallet).\n<br />\nEach accumulation should be done in a new highly secured wallet, but these are easy to create, i.e. you can\nmemorize a long passphrase and add a counter at the end (1 for the first accumlation, 2 for the second, etc.).\n<br />\nFor more details, visit: <a target=\"_blank\" href=\"https://timelockrecovery.com\" rel=\"noopener noreferrer\">https://timelockrecovery.com</a>.\n<br />\nBefore we begin, please note:\n<ol>\n    <li>\n        Please prepare in advance the addresses of your inheritors/backup-wallets.\n    </li>\n    <li>\n        Since we are preparing this recovery plan for the long future, it is hard\n        to estimate what the required mining fees will be.\n        If the fee is too low, your inheritors, who don't have access to the master\n        keys, will not be able to simply \"replace-by-fee\" and use a higher fee.\n        At the moment of writing this code (year 2025) this is not a big deal, because\n        there are acceleration-services, such as\n        <a target=\"_blank\" href=\"https://mempool.space/accelerator\" rel=\"noopener noreferrer\">\n            mempool.space's accelerator\n        </a>, that allows to boost selected transactions for direct payment.\n        Just in case this service will not be available in the future, the\n        <i>Alert Transaction</i> will send a small amount of 600 sats to each\n        destination address. This will allow advance users to boost the\n        first transaction by spending their unmined UTXO in a mechanism called\n        Child-Pay-For-Parent.\n    </li>\n</ol>\n"

It could be changed to utilise multiple threads\n# but any serious attempt would need at least GPU acceleration.\n#\n# There are two main types of password encryption that need to be disambiguated\n# for Electrum wallets:\n# (1) keystore-encryption: The wallet file itself is mostly plaintext (json),\n#                          only the Bitcoin private keys themselves are encrypted.\n#                          (e.g. seed words, xprv are encrypted; addresses are not)\n#                          Even in memory (at runtime), the private keys are typically\n#                          stored encrypted, and only when needed the user is prompted\n#                          for their password to decrypt the keys briefly.\n# (2) storage-encryption: The file itself is encrypted. When opened in a text editor,\n#                         it is base64 ascii text. Normally storage-encrypted wallets\n#                         also have keystore-encryption (unless they don't have private keys).\n# Storage-encryption was introduced in Electrum 2.8, keystore-encryption predates that.\n# Newly created wallets in modern Electrum have storage-encryption enabled by default.\n#\n# Storage encryption uses a stronger KDF than keystore-encryption.\n# As is, this script can test around ~1000 passwords per second for storage-encryption.\n\nimport sys\nfrom string import digits, ascii_uppercase, ascii_lowercase\nfrom itertools import product\nfrom typing import Callable\nfrom functools import partial\n\nfrom electrum.wallet import Wallet, Abstract_Wallet\nfrom electrum.storage import WalletStorage\nfrom electrum.wallet_db import WalletDB\nfrom electrum.simple_config import SimpleConfig\nfrom electrum.util import InvalidPassword\n\n\nALLOWED_CHARS = digits + ascii_uppercase + ascii_lowercase\nMAX_PASSWORD_LEN = 12\n\n\ndef test_password_for_storage_encryption(storage: WalletStorage, password: str) -> bool:\n    try:\n        storage.decrypt(password)\n    except InvalidPassword:\n        return False\n    else:\n        return True\n\n\ndef test_password_for_keystore_encryption(wallet: Abstract_Wallet, password: str) -> bool:\n    try:\n        wallet.check_password(password)\n    except InvalidPassword:\n        return False\n    else:\n        return True\n\n\ndef bruteforce_loop(test_password: Callable[[str], bool]) -> str:\n    num_tested = 0\n    for pw_len in range(1, MAX_PASSWORD_LEN + 1):\n        for pw_tuple in product(ALLOWED_CHARS, repeat=pw_len):\n            password = \"\".join(pw_tuple)\n            if test_password(password):\n                return password\n            num_tested += 1\n            if num_tested % 5000 == 0:\n                print(f\"> tested {num_tested} passwords so far... most recently tried: {password!r}\")\n\n\nif __name__ == '__main__':\n    if len(sys.argv) < 2:\n        print(\"ERROR. usage: bruteforce_pw.py <path_to_wallet_file>\")\n        sys.exit(1)\n    path = sys.argv[1]\n\n    config = SimpleConfig()\n    storage = WalletStorage(path)\n    if not storage.file_exists():\n        print(f\"ERROR. wallet file not found at path: {path}\")\n        sys.exit(1)\n    if storage.is_encrypted():\n        test_password = partial(test_password_for_storage_encryption, storage)\n        print(f\"wallet found: with storage encryption.\")\n    else:\n        db = WalletDB(storage.read(), storage=storage, upgrade=False)\n        wallet = Wallet(db, config=config)\n        if not wallet.has_password():\n            print(\"wallet found but it is not encrypted.\")\n            sys.exit(0)\n        test_password = partial(test_password_for_keystore_encryption, wallet)\n        print(f\"wallet found: with keystore encryption.\")\n    password = bruteforce_loop(test_password)\n    print(f\"====================\")\n    print(f\"password found: {password}\")\n"

We only persist the current batch in self.batch_txids.\n# Thus, if we need to broadcast tx2 or tx2', then self.batch_txids is reset, and the old batch is forgotten.\n#\n# If we cannot RBF a transaction (because the server returns an error), then we create a new batch,\n# as if the transaction had been mined.\n#   if cannot_rbf(tx1)  -> broadcast tx2(tx1,o2). The new base is now tx2(tx,o2)\n#   if cannot_rbf(tx1') -> broadcast tx3(tx1'|o3)\n#\n#\n# Notes:\n#\n# 1. CPFP:\n# When a batch is forgotten but not mined (because the server returned an error), we no longer bump its fee.\n# However, the current code does not treat the next batch as a CPFP when computing the fee.\n#\n# 2. Reorgs:\n# This code does not guarantee that a payment or a sweep will happen.\n# This is fine for sweeps; it is the responsibility of the caller (lnwatcher) to add them again.\n# To make payments reorg-safe, we would need to persist more data and redo failed payments.\n#\n# 3. batch_payments and batch_inputs are not persisted.\n# In the case of sweeps, lnwatcher ensures that SweepInfo is added again after a client restart.\n# In order to generalize that logic to payments, callers would need to pass a unique ID along with\n# the payment output, so that we can prevent paying twice.\n#\n# - nLocktime/CLTV values (bip-65) and nSequence/CSV values (bip-112) are either explicitly\n#   or implicitly block-height-based everywhere in this file.\n#   SCRIPT execution fails on height vs timestamp confusion, and\n#   it is not safe to do naive integer comparison between these values without establishing type.\n#   TODO review this is correct, and add checks.\n#    nLocktime/CLTV usage in particular seems dangerously *implicit* for being block-heights\n\nimport asyncio\nimport threading\nimport copy\nfrom typing import Dict, Sequence, Optional, TYPE_CHECKING, Mapping, Set, List, Tuple\n\nfrom . import util\nfrom .bitcoin import dust_threshold\nfrom .logging import Logger\nfrom .util import log_exceptions, NotEnoughFunds, BelowDustLimit, NoDynamicFeeEstimates, OldTaskGroup\nfrom .transaction import PartialTransaction, PartialTxOutput, Transaction, TxOutpoint, PartialTxInput\nfrom .address_synchronizer import TX_HEIGHT_LOCAL, TX_HEIGHT_FUTURE\nfrom .lnsweep import SweepInfo\nfrom .json_db import locked, StoredDict\nfrom .fee_policy import FeePolicy\n\nif TYPE_CHECKING:\n    from .wallet import Abstract_Wallet\n\n\nclass TxBatcher(Logger):\n\n    SLEEP_INTERVAL = 1\n\n    def __init__(self, wallet: 'Abstract_Wallet'):\n        Logger.__init__(self)\n        self.lock = threading.RLock()\n        self.storage = wallet.db.get_stored_item(\"tx_batches\", {})\n        self.tx_batches = {}  #
