(If you've come here looking to simply run Electrum-GRS, you may download it here.)
Electrum-GRS 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-dev
$ ELECTRUM_ECC_DONT_COMPILE=1 python3 -m pip install --user ".[gui,crypto]"
If you want to use the Qt interface, install the Qt dependencies:
$ sudo apt-get install python3-pyqt6
For elliptic curve operations, libsecp256k1 is a required dependency.
If you "pip install" Electrum-GRS, by default libsecp will get compiled locally,
as part of the electrum-ecc dependency. This can be opted-out of,
by setting the ELECTRUM_ECC_DONT_COMPILE=1 environment variable.
For the compilation to work, besides a C compiler, you need at least:
$ sudo apt-get install automake libtool
If you opt out of the compilation, you need to provide libsecp in another way, e.g.:
$ sudo apt-get install libsecp256k1-dev
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.
If you downloaded the official package (tar.gz), you can run Electrum-GRS 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_grs
You can also install Electrum-GRS 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-GRS instead of using the 'packages' directory.
It will also place an executable named electrum-grs in ~/.local/bin,
so make sure that is on your PATH variable.

Check out the code from GitHub:
$ git clone https://github.com/Groestlcoin/electrum-grs.git
$ cd electrum-grs
$ git submodule update --init
Run install (this should install dependencies):
$ python3 -m pip install --user -e .
Create translations (optional):
$ sudo apt-get install python3-requests gettext qttools5-dev-tools
$ ./contrib/pull_locale
Finally, to start Electrum-GRS:
$ ./run_electrum_grs
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-GRS development happens on IRC, in the
#groestlcoin channel on Libera Chat. The easiest way to participate on IRC is
with the web client, web.libera.chat.
