ElectrumSV - Lightweight Bitcoin SV client

Licence: Open BSV
Maintainers: Neil Booth, Roger Taylor, AustEcon
Project Lead: Roger Taylor
Language: Python (>=3.7.8)
Homepage: https://electrumsv.io/

Getting started on Linux/MacOS

ElectrumSV is a Python-based application forked from Electrum. If you want to use the graphical user interface, install the Qt dependencies:

(LINUX) sudo apt-get install python3-pyqt5
(MacOS) brew install pyqt5

If you are running from the Github repository, you are advised to use the latest release branch, which at this time is releases/1.3. The master branch is used for the latest development changes and is not guaranteed to be as stable, or to have guaranteed long term support for some of the more advanced features we may have added and later remove.

Ensuring you have at least Python 3.7.8

You need to ensure you can use Python 3.7.8, ensure the following command looks like this:

$ python3 --version
Python 3.7.8

If you see a lower version, you can use pyenv to install Python 3.7.8. First install pyenv:

curl -L https://raw.githubusercontent.com/pyenv/pyenv-installer/master/bin/pyenv-installer | bash

Edit your .bashrc file as described, and then ensure the changes are put into effect:

$ source ~/.profile

Now you can install Python 3.7.8 using pyenv:

$ pyenv install 3.7.8

If you encounter errors during that process, you can refer to the pyenv common problems.

At this point, you should be able to make Python 3.7.8 the default Python on your computer:

$ pyenv global 3.7.8

And you can check that your python3 version is indeed 3.7.8, by confirming the following command now looks like this:

$ python3 --version
Python 3.7.8

Ensuring you have at least Sqlite 3.31.1

ElectrumSV MacOS and Windows builds come with at least Sqlite version 3.31.1, but there are no Linux builds, and both Linux and MacOS users may wish to upgrade or make available the Sqlite version on their computer.

Linux:

$ python3 -m pip install -U pysqlite3-binary
$ python3 -c "import pysqlite3; print(pysqlite3.sqlite_version)"
3.31.1

MacOS:

$ brew upgrade sqlite3
$ python3 -c "import sqlite3; print(sqlite3.sqlite_version)"
3.31.1

You may see a different version displayed than 3.31.1, but as long as it is higher, this is fine.

Installing other dependencies

To run ElectrumSV from its top-level directory, first install the core dependencies:

pip3 install --user -r contrib/deterministic-build/requirements.txt
pip3 install --user -r contrib/deterministic-build/requirements-binaries.txt

If you have a hardware wallet, or want to ensure that the hardware wallet support can work, install their specific dependencies:

pip3 install --user -r contrib/deterministic-build/requirements-hw.txt

Then invoke it as so:

./electrum-sv

You can also proceed onward from this point and install ElectrumSV on your system. This will download and install most dependencies used by ElectrumSV. This is useful if you with to use the electrumsv Python library, perhaps for Bitcoin application development using ElectrumSV as a wallet server. And of course it should make the electrum-sv command accessible for use.

In order to do so, run these commands:

pip3 install --user -r contrib/deterministic-build/requirements-binaries.txt
pip3 install .

Problem Solving

If you choose to use Linux, you introduce complexity and uncertainty into the process. It is not possible to know all the unique choices you have made regarding it. The following tips may help work around problems you encounter.

Errors relating to "wheels"

If you encounter problems referring to wheels, make sure you have installed the wheel package:

pip3 install --user wheel

Errors relating to "libusb" installing the pip3 requirements

Install the following:

sudo apt install libusb-1.0.0-dev libudev-dev

Errors relating to "Python.h"

If you encounter problems referring to "Python.h", first check your Python version:

python3 --version

If it says "3.6", then install the following:

sudo apt install python3.6-dev

If it says "3.7", then install the following:

sudo apt install python3.7-dev

If it says a later version of Python, you should be able to figure out what to do.

Scanning QR codes

If you need to enable QR code scanning functionality, install the following:

sudo apt-get install zbar-tools

Getting started on Windows

The easiest way to run ElectrumSV on Windows, is to obtain an executable for the latest version from our website. This Git repository has a build-hashes.txt which should contain SHA-256 hashes for all our downloads. You can confirm that you have downloaded a valid file, by comparing it's SHA-256 hash to the hash we provide for the same file name.

You can also run from the Git repository directly, which is useful if you wish to customise or help us develop ElectrumSV.

You need to be sure that you are using a version of Python either 3.7.8 or higher. And that the version you are using has a version of Sqlite either 3.31.1 or higher. If you are for instance using a version of Python 3.8 that has a lower version of Sqlite, then update your Python 3.8 installation.

To run ElectrumSV from its top-level directory, first install the core dependencies:

pip3 install --user -r contrib\deterministic-build\requirements.txt
pip3 install --user -r contrib\deterministic-build\requirements-binaries.txt

If you have a hardware wallet, or want to ensure that the hardware wallet support can work, install their specific dependencies:

pip3 install --user -r contrib\deterministic-build\requirements-hw.txt

Then invoke it as so:

py -3 electrum-sv

You can also install ElectrumSV on your system. This will download and install most dependencies used by ElectrumSV. This is useful if you with to use the electrumsv Python library, perhaps for Bitcoin application development using ElectrumSV as a wallet server.

In order to do so, run these commands:

pip3 install --user -r contrib\deterministic-build\requirements-binaries.txt
pip3 install .

Extra development notes

Check out the code from Github:

git clone https://github.com/ElectrumSV/ElectrumSV
cd ElectrumSV

Run the pip installs (this should install dependencies):

pip3 install .

Create translations (optional):

sudo apt-get install python-requests gettext
./contrib/make_locale

Running unit tests (with the pytest package):

pytest electrumsv/tests

Running pylint:

pylint --rcfile=.pylintrc electrum-sv electrumsv

Running mypy:

mypy --config-file mypy.ini --python-version 3.7

Builds

Builds are created automatically for Git commits through the Azure Pipelines CI services which Microsoft and Github kindly make available to us.

The easiest way for you to create builds is to fork the project, and to link it to Azure Pipelines and they should also happen automatically. If you wish to look at the specific code that handles a given part of the build process, these will be referenced below for the various operating systems. To see how these are engaged, refer to the Azure Pipelines YAML files.

Source Archives

Run the following to create the release archives under dist/:

./contrib/make_source_archives.py

Mac OS X / macOS

See contrib/osx/.

Windows
