Developer overview

Finney's DEV · CONSOLE

An arcade of on-chain games, settled in finney (10^-3 eth) — a nod to Hal. This is the developer face of the box. Game #1 is Three Kings — Kings-in-the-Corner, on-chain. Play it on the public testnet at testnet.finneys.dev (Base Sepolia, free with faucet funds), or on the local dev chain at anvil.finneys.dev.
