(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 tar.gz or from source.
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. You will need to install a few system dependencies:
To use the desktop GUI (Qt6):
$ sudo apt-get install python3-pyqt6
Due to the need for fast symmetric ciphers, cryptography is required. Install from your package manager:
$ sudo apt-get install python3-cryptography
To run Electrum from its root directory, just do:
$ ./run_electrum
This method currently lacks hardware wallet support. If you need hardware wallet support, you should install as described below
$ python3 -m venv $HOME/electrum
When the virtualenv
is created or already exists, activate it:
$ . $HOME/electrum/bin/activate
$ pip install .[gui,crypto,hardware]
This will install Electrum and all required dependencies, including for Qt desktop GUI and hardware wallets.
For elliptic curve operations, libsecp256k1 is a required dependency:
$ sudo apt-get install libsecp256k1-dev
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
For more information about hardware wallet dependencies, see this.
To run Electrum, just do:
$ electrum
Or, without first activating the virtualenv
:
$ $HOME/electrum/bin/electrum
(For OS-specific instructions, see here for Windows, and for macOS)
$ git clone https://github.com/spesmilo/electrum.git
$ cd electrum
$ git submodule update --init
$ python3 -m venv $HOME/electrum
$ . $HOME/electrum/bin/activate
$ pip install -e .[gui,crypto,hardware]
Create translations (optional):
$ sudo apt-get install python3-requests gettext qt6-l10n-tools
$ ./contrib/pull_locale
Finally, to start Electrum:
$ ./run_electrum
Run unit tests with pytest
:
$ pytest tests -v
To run a single file, specify it directly like this:
$ pytest tests/test_bitcoin.py -v
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.
