L2 Node Setup

This guide will show you how to set up an L2 execution node (op-geth) and a rollup node (op-node) for your OP Stack chain.

Instructions

1. Clone simple-optimism-node and follow the instructions in the README to set up your rollup.
2. Ensure you configure the rollup with NODE_TYPE=archive and OP_GETH__SYNCMODE=snap. With this, you will be able to prove blocks in OP Succcinct using blocks after the snap sync.

Your op-geth endpoint will be available at the RPC port chosen here, which in this case is 8545 (e.g. http://localhost:8545).

Your op-node endpoint (rollup node) will be available at the RPC port chosen here, which in this case is 9545 (e.g. http://localhost:9545).

Check Sync Status

After a few hours, your node should be fully synced and you can use it to begin generating ZKPs.

To check your node's sync status, you can run the following commands:

op-geth:

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

op-node:

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