python -m pip install eth-utils

Developer Setup

If you would like to hack on eth-utils, please check out the Snake Charmers Tactical Manual for information on how we do:

  • Testing
  • Pull Requests
  • Documentation

We use pre-commit to maintain consistent code style. Once installed, it will run automatically with every commit. You can also run it manually with make lint. If you need to make a commit that skips the pre-commit checks, you can do so with git commit --no-verify.

Development Environment Setup

You can set up your dev environment with:

git clone
cd eth-utils
virtualenv -p python3 venv
. venv/bin/activate
python -m pip install -e ".[dev]"
pre-commit install

Update Networks

The list of networks resides in the JSON file under eth_utils/__json/eth_networks.json. This file is used to initialize Networks, which can be used to obtain network information with a chain ID.

Run the script to update the JSON file with the response from the remote list.


If there are new networks they will appear in the JSON file. After checking the updates, open a PR to make them available in a new release.

Release setup

To release a new version:

make release bump=$$VERSION_PART_TO_BUMP$$

How to bumpversion

The version format for this repo is {major}.{minor}.{patch} for stable, and {major}.{minor}.{patch}-{stage}.{devnum} for unstable (stage can be alpha or beta).

To issue the next version in line, specify which part to bump, like make release bump=minor or make release bump=devnum. This is typically done from the main branch, except when releasing a beta (in which case the beta is released from main, and the previous stable branch is released from said branch).

If you are in a beta version, make release bump=stage will switch to a stable.

To issue an unstable version when the current version is stable, specify the new version explicitly, like make release bump="--new-version 4.0.0-alpha.1 devnum"
