Ethereum.nix = Ethereum 🫶 Nix

Ethereum.nix is a collection of Nix packages and NixOS modules designed to make it easier to operate Ethereum related services and infrastructure.

For the uninitiated, using Ethereum.nix will give you the following benefits:

• Access to a wide range of Ethereum applications packaged with Nix, ready to run without fuss. Nix guarantees you don't have to worry about version conflicts, missing dependencies or even what state your OS is in.
• We aim that every Ethereum application stored in the repository is constructed from its source, including all input dependencies. This approach guarantees the code's reproducibility and trustworthiness. Furthermore, with Nix, expert users can tweak and adjust the build process to any degree of detail as required.
• We develop custom NixOS modules to streamline operations with applications such as Execution and Consensus clients (including performing backups). Moreover, we aim to introduce further abstractions that simplify everyday tasks, such as running a development environment effortlessly without needing docker.

This project is developed entirely in Nix Flakes (but it offers compatibility with legacy Nix thanks to flake-compat).

Documentation

We recommend you look at our documentation that shows how to use Ethereum.nix effectively.

Any PR improving documentation is welcome.

Requirements

To make the most of this repository, you should have the following installed:

• Nix
• Direnv

After cloning this repository and entering inside, run direnv allow when prompted, and you will be met with the previous prompt.

Docs

To build the docs locally, run docs build. The output will be inside of ./result.

Run docs serve to serve the docs locally (after building them previously). You can edit the docs in ./docs.

Running tests

To run all tests, you can use check (alias for nix flake check); it will build all packages and run all tests.

You can use tests -h to execute a specific test, which will provide more information.

Formatting

You can manually format the source using the fmt command.
