Set Up A Node

Overview

Unichain (including Unichain Sepolia Testnet) runs on the OP Stack as part of the Superchain. The Optimism team has produced extensive docs on how to run Superchain nodes, we highly recommend you familiarize yourself with them before proceeding.

Manually Running Unichain Sepolia Nodes

If you would like to manually run op-node & op-geth, you can do so normally with the following chain config & L2 Genesis:

• Rollup.json
• genesis-l2.json

For op-node, do not set --network and instead set --rollup.config=<PATH_TO_ROLLUP.JSON>

For op-geth, do not set --op-network and instead run geth init --datadir <PATH_TO_DATADIR> genesis-l2.json

Uniswap Labs provides the following bootnodes (snap sync enabled):
