Install from source

Prerequisites

Make sure to have Yarn installed. It is also recommended to install NVM (Node Version Manager) and use the LTS version (currently v20) of NodeJS.

Info

NodeJS versions older than the current LTS are not supported by Lodestar. We recommend running the latest Node LTS. It is important to make sure the NodeJS version is not changed after reboot by setting a default nvm alias default <version> && nvm use default.

Note

Node Version Manager (NVM) will only install NodeJS for use with the active user. If you intend on setting up Lodestar to run under another user, we recommend using NodeSource's source for NodeJS so you can install NodeJS globally.

Clone repository

Clone the repository locally and build from the stable release branch.

git clone -b stable https://github.com/chainsafe/lodestar.git

Switch to created directory.

cd lodestar

Install packages

Install across all packages. Lodestar follows a monorepo structure, so all commands below must be run in the project root.

yarn install

Build source code

Build across all packages.

yarn run build

Lodestar CLI
