Install Binaries

Use baseup to install the GitHub release binaries for this repository:

curl -fsSL https://raw.githubusercontent.com/base/base/main/baseup/install | bash

Run a Node

This repository now hosts the public Base node previously published from base/node. Root docker-compose.yml pulls ghcr.io/base/node. Pass --build to compile this tree. For local development, see Run a Local Devnet.

1. Set BASE_NODE_L1_ETH_RPC and BASE_NODE_L1_BEACON in .env.mainnet or .env.sepolia.
2. Start the node:

# Mainnet (default):
docker compose up --build

# Testnet:
NETWORK_ENV=.env.sepolia docker compose up --build

# Pin a published image (no compile):
NODE_TAG=v1.3.0 docker compose up

See the docs for hardware requirements, snapshots, and historical proofs.

Run a Local Devnet

Devnet	Use it for	Start
Docker devnet	A fresh L1 and L2 stack: sequencing, derivation, batching, hardfork activation	just devnet up-single
Snapshot devnet	Real Base Mainnet state and contracts, acting as any account, 200ms blocks; no L1	just devnet snapshot download --dir <dir>, then just devnet snapshot run --dir <dir>

Start with the Run a Local Devnet guide. docs/guides/DEVNET.md covers every local environment in this repository.

Base Anvil Package

Every push to main publishes patched anvil and forge binaries to GHCR as ghcr.io/base/base-anvil. Use immutable sha-<commit> tags for pinned downstream tests, or main for the latest successful main build.
