System Requirements

DISK

4-8 cores

Ubuntu 24.04

5TB

The Optimism Sepolia Archive Node has a size of 2.3TB as of 3/10/2025.

Subgraphs using callHandlers requires the RPC client to support the Parity Tracing API. With Optimism sepolia we observe that erigon supports the parity tracing API, while geth does not. This guide shows how to set up a geth client.

Pre-Requisites

Update System

sudo apt update -y && sudo apt upgrade -y && sudo apt autoremove -y
sudo apt install -y git gcc make --fix-missing

Installl Docker

# Update and upgrade packages
sudo apt-get update
sudo apt-get upgrade -y

### Docker and docker compose prerequisites
sudo apt-get install -y curl
sudo apt-get install -y gnupg
sudo apt-get install -y ca-certificates
sudo apt-get install -y lsb-release

### Download the docker gpg file to Ubuntu
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

### Add Docker and docker compose support to the Ubuntu's packages list
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt-get update
 
### Install docker and docker compose on Ubuntu
sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin

sudo usermod -aG docker $(whoami)

sudo docker run hello-world

Firewall Configuration

Set Explicit Firewall Configuration

sudo ufw default deny incoming && sudo ufw default allow outgoing

Allow SSH

sudo ufw allow 22/tcp

Allow Connections for OP-NODE & OP-GETH

sudo ufw allow 8546
sudo ufw allow 9545
sudo ufw allow 8545
sudo ufw allow 3000

Enable Firewall Rules

sudo ufw enable

Check Status of Firewall Rules (UFW)

sudo ufw status verbose

Clone the Optimism Docker Setup Directory

Create Directories

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

Copy .env.example to .env

cp .env.example .env

Configure the .env file

This is a sample of how to configure the .env for op-sepolia node

If port 8545 isn't working, you can connect to the default port for the l2 geth execution node port - 9993

Grafana dashboard

Grafana is exposed at http://localhost:3000 and comes with one pre-loaded dashboard ("Simple Node Dashboard").

Use the following login details to access the dashboard:

Username: admin
Password: optimism

Query Node

Check Sync Status

curl -H "Content-Type: application/json" \
-X POST --data '{"jsonrpc":"2.0", "method":"eth_syncing", "params":[], "id":1}' \
http://localhost:8545 or 9993

# If node is done syncing - the response should resemble the below.
{"jsonrpc":"2.0","id":1,"result":false}

Check optimism sync status

curl -X POST -H "Content-Type: application/json" --data \
    '{"jsonrpc":"2.0","method":"optimism_syncStatus","params":[],"id":1}'  \
    http://localhost:9545

{"jsonrpc":"2.0","id":1,"result":{"current_l1":{"hash":"0xda1a28e8d035386478138aa1941d324bf39ac9ff57f4fbcf72ff98450f2c2590","number":7876040,"parentHash":"0x3a3a56dd92718df3b55ad48d3b8adfcf2a1741f7ec1478b9ec9bcf152a4dbc26","timestamp":1741642332},"current_l1_finalized"....

Check Block Number

curl -H "Content-Type: application/json" \
-X POST --data '{"jsonrpc":"2.0", "method":"eth_blockNumber", "params":[], "id":1}' \
http://localhost:8545 or 9993

# Response should resemble the below.
{"jsonrpc":"2.0","id":1,"result":"0x17c3e4e"}
