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.
Check out the Unichain Node Repository
for an easy to use node setup. This correctly configures op-node and op-geth for unichain-sepolia.
If you would like to manually run op-node & op-geth, you can do so normally with the following chain config & L2 Genesis:
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 on unichain-sepolia:
