Op-Erigon Base Sepolia archive node has a size of ???GB on March 31th, 2025

Base is a secure, low-cost Ethereum L2 built on Optimism’s open-source OP Stack. In this guide, we cover docker installation of op-erigon and op-nodeto facilitate the node's synchronization on Sepolia Testnet Network. This method is expected to sync an archive node successfully in ~week using the snapshot provided by Testinprod-io

Before you start, make sure that you have your own synced Ethereum Sepolia L1 RPC URL and L1 Consensus Layer Beacon endpoint (e.g. Lighthouse Sepolia) ready

Pre-Requisites

sudo apt update -y && sudo apt upgrade -y && sudo apt autoremove -y
​
sudo apt install -y wget curl screen git ufw zstd

Setting up Firewall

sudo ufw default deny incoming
sudo ufw default allow outgoing

sudo ufw allow 22/tcp
sudo ufw allow 80
sudo ufw allow 443

Enable Firewall

sudo ufw enable

Install Docker

Run this command to remove any conflicting docker

for pkg in docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc; do sudo apt-get remove $pkg; done

Add Docker's official GPG key:

sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

Add the repository to ppt sources:

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
  
sudo apt-get update

Install docker

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

# Test docker is working
sudo docker run hello-world

#Install docker compose

sudo apt-get update
sudo apt-get install docker-compose-plugin

# Test the docker version
docker compose version

Setting up a domain name to access RPC

Get the IP address of the host machine, you can use the following command in a terminal or command prompt

curl ifconfig.me

Set an A record for a domain, you need to access the domain's DNS settings and create an A record that points to the IP address of the host machine. This configuration allows users to reach your domain by resolving the domain name to the specific IP address associated with your host machine.

Create Base Sepolia directory

mkdir base-sepolia && cd base-sepolia

Create .env file

sudo nano .env

Paste the following into the file.

EMAIL={YOUR_EMAIL} #Your email to receive SSL renewal emails
DOMAIN={YOUR_DOMAIN} #Domain should be something like rpc.mywebsite.com, e.g. base-sepolia.infradao.org
WHITELIST={YOUR_REMOTE_MACHINE_IP} #the server's own IP and comma separated list of IP's allowed to connect to RPC (e.g. Indexer)
LAYER_1_RPC={YOUR_L1_RPC} #Your ready synced L1 Ethereum Sepolia node RPC endpoint
L1_BEACON={YOUR_L1_BEACON} #Your synced L1 CL (Consensus Layer) Beacon endpoint, e.g. Lighthouse (Prysm, Lodestar) Sepolia

Ctrl + x and y to save file

Make sure L1_BEACON endpoint provides full historical blobs data. Otherwise you won't be able to sync

Create JWT secret file

mkdir -p /root/data/base-sepolia/op-erigon/ && cd /root/data/base-sepolia/op-erigon/

openssl rand -hex 32 | tr -d "\n" > "./jwt.hex"

Optional/Recommended: Download Base Snapshot

This is an optional step based on whether you want to sync the node from scratch or sync the node from a snapshot. Based on InfraDAO’s experience, we recommend downloading a snapshot and syncing the node from that snapshot. Syncing the node from scratch will take weeks while the op-erigon snapshot requires much shorter time to download, some time to extract, and about a week to sync from that point.

To sync from a snapshot, visit Testinprod-io Node Snapshots page to find a latest Base Sepolia archive for Op-Erigon: https://snapshot.testinprod.io/.

As downloading a snapshot takes some time it is good idea to run it in a screen session

screen -S erigon

Use aria2c to download the most recent Base Sepolia Op-Erigon Archive Snapshot

cd /root/base-sepolia

aria2c --file-allocation=none -c -x 15 -s 15 https://datadirs.testinprod.io/base-sepolia-db-13833382.zst

press ctrl+A and D to return to previous screen and continue installation

screen -r erigon #will bring you back to monitor downloading progress

You'll need to extract the downloaded snapshot and move its contents to the op-erigon-data directory, where Docker stores persistent data.

zstd -d base-sepolia-db-13833382.zst -c | tar xvf -
# replace the archive with an actual name

If you initially tried to sync the node from scratch and are now trying with a snapshot make sure to empty the destination directory first:

cd /var/lib/docker/volumes/base-sepolia_op-erigon_data/_data 

ls 

#if directory isn't empty remove contents of chaindata directory

rm -rf ~/chaindata/*

mv /root/base-sepolia/mdbx.dat /var/lib/docker/volumes/base-sepolia_op-erigon_data/_data/chaindata

cd /var/lib/docker/volumes/base-sepolia_op-erigon_data/_data/chaindata

ls #to check if archive has moved properly

If you haven't started the node yet, create op-erigon-data directory first:

docker volume create base-sepolia_op-erigon_data

cd /var/lib/docker/volumes/base-sepolia_op-erigon_data/_data

mv /root/base-sepolia/mdbx.dat /var/lib/docker/volumes/base-sepolia_op-erigon_data/_data/

ls

Launch Base Sepolia

IMPORTANT: During synchronization you will need to switch versions of op-node and op-erigon in order to escape Ahead with major recommended protocol version mismatch issue:

See avaialable images for op-erigon here: https://hub.docker.com/r/testinprod/op-erigon/tags

for op-node here: https://github.com/ethereum-optimism/optimism/releases

cd /root/base-sepolia

sudo nano docker-compose.yml

Monitor Logs

Use docker logs to monitor your op-erigon and op-node. The -f flag ensures you are following the log output

docker logs op-erigon -f --tail 100

docker logs opnode -f --tail 100

Once your Base Sepolia node starts syncing, the logs should look like this:

for op-erigon:

curl --data '{"method":"eth_syncing","params":[],"id":1,"jsonrpc":"2.0"}' -H "Content-Type: application/json" -X POST https://{YOUR_DOMAIN}

The result will return false if a node is fully synced

Alternatively you can run

curl -d '{"id":0,"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["latest",false]}' \
  -H "Content-Type: application/json" https://{YOUR_DOMAIN}

and it will return more details about syncing progress

Sync speed will be highly dependent on your Layer 1 RPC
