Install from source

Make sure to have Yarn installed. It is also recommended to install NVM (Node Version Manager) and use v16 of NodeJS.

Info

NodeJS versions < 16.x are not supported by Lodestar. We currently recommend running NodeJS 16.x.

Clone the repo locally.

git clone https://github.com/chainsafe/lodestar.git

Install across all packages. Lodestar follows a monorepo structure, so all commands below must be run in the project root. Use the --ignore-optional flag to prevent downloading the Ethereum Consensus spec tests.

yarn install --ignore-optional

Build across all packages.

yarn run build

Or if you are using Lerna:

lerna bootstrap

Lodestar should now be ready for use.

./lodestar --help
