How it works

1
You submit your L2 address. The faucet validates it and checks rate limits.
2
The faucet calls OptimismPortalHash.depositTransaction on Sepolia L1, sending 0.01 ETH.
3
The op-node derives a deposit tx from the L1 event. Your L2 balance updates within ~2 minutes.
4
No ECDSA signing happens on L2 — the deposit is authenticated by the L1 transaction itself.
