Optimism

Instructions to set up your Optimism node.

ℹ️

Note: Mainnet instructions here will only work after the bedrock upgrade is live on mainnet

Requirements

Prerequisites

sudo apt-get install jq -y
snap install docker

Clone Repo

git clone https://github.com/smartcontracts/simple-optimism-node.git
cd simple-optimism-node
cp .env.example .env

Set node config

Set the following config options in simple-optimism-node/.env:

NETWORK_NAME=mainnet
NODE_TYPE=full
BEDROCK_SOURCE=download
# Your Ethereum RPC node endpoint. As an L2, your Optimism node will verify tx finality by
# querying your own Ethereum RPC node.
OP_NODE__RPC_ENDPOINT=
OP_NODE__RPC_TYPE=basic

Start the node

docker compose up -d

This should show an output like this:

After it is done, verify by listing the services and their status

docker compose ps

You should see these 4 services running

Check logs

Verify op-geth logs

docker compose logs op-geth -f

It will download the bedrock.tar
