fixes https://github.com/spesmilo/electrum/issues/7780 fixes https://github.com/spesmilo/electrum/issues/7815 Re FIXME in main_window.py, in particular, adb might call `add_transaction` on the same tx multiple times. In `wallet.on_event_adb_added_tx`, maybe we should propagate `notify_GUI` to `wallet._update_request_statuses_touched_by_tx`. The issue being fixed here (above TARS reports) can be triggered in multiple ways, e.g.: - have an already paid receive request, and receive a payment to the same address again - have an already paid receive request, and *spend from* that address (in which case the history of the address will change, and address_synchronizer will call add_transaction again on the old tx that satisfied the old receive request)
Electrum - Lightweight Bitcoin client
Licence: MIT Licence
Author: Thomas Voegtlin
Language: Python (>= 3.8)
Homepage: https://electrum.org/
Getting started
(If you've come here looking to simply run Electrum, you may download it here.)
Electrum itself is pure Python, and so are most of the required dependencies, but not everything. The following sections describe how to run from source, but here is a TL;DR:
$ sudo apt-get install libsecp256k1-0
$ python3 -m pip install --user ".[gui,crypto]"
Not pure-python dependencies
If you want to use the Qt interface, install the Qt dependencies:
$ sudo apt-get install python3-pyqt5
For elliptic curve operations, libsecp256k1 is a required dependency:
$ sudo apt-get install libsecp256k1-0
Alternatively, when running from a cloned repository, a script is provided to build libsecp256k1 yourself:
$ sudo apt-get install automake libtool
$ ./contrib/make_libsecp256k1.sh
Due to the need for fast symmetric ciphers, cryptography is required. Install from your package manager (or from pip):
$ sudo apt-get install python3-cryptography
If you would like hardware wallet support, see this.
Running from tar.gz
If you downloaded the official package (tar.gz), you can run Electrum from its root directory without installing it on your system; all the pure python dependencies are included in the 'packages' directory. To run Electrum from its root directory, just do:
$ ./run_electrum
You can also install Electrum on your system, by running this command:
$ sudo apt-get install python3-setuptools python3-pip
$ python3 -m pip install --user .
This will download and install the Python dependencies used by
Electrum instead of using the 'packages' directory.
It will also place an executable named electrum in ~/.local/bin,
so make sure that is on your PATH variable.
Development version (git clone)
(For OS-specific instructions, see here for Windows, and for macOS)
Check out the code from GitHub:
$ git clone https://github.com/spesmilo/electrum.git
$ cd electrum
$ git submodule update --init
Run install (this should install dependencies):
$ python3 -m pip install --user -e .
Create translations (optional):
$ sudo apt-get install python-requests gettext
$ ./contrib/pull_locale
Finally, to start Electrum:
$ ./run_electrum
Run tests
Run unit tests with pytest:
$ pytest electrum/tests -v
To run a single file, specify it directly like this:
$ pytest electrum/tests/test_bitcoin.py -v
Creating Binaries
Contributing
Any help testing the software, reporting or fixing bugs, reviewing pull requests and recent changes, writing tests, or helping with outstanding issues is very welcome. Implementing new features, or improving/refactoring the codebase, is of course also welcome, but to avoid wasted effort, especially for larger changes, we encourage discussing these on the issue tracker or IRC first.
Besides GitHub,
most communication about Electrum development happens on IRC, in the
#electrum channel on Libera Chat. The easiest way to participate on IRC is
with the web client, web.libera.chat.
