For on-chain games, players will be asked to use their wallet to sign a Stake to enter a match. The Stake object is an EIP712 record () that guarantees later payment of entry fee.

Once signed, the Hangman server hangs onto this signature. On completion of the match by both parties, the Hangman server submits both player's signed stakes, as well as the winner to the contract. The contract itself is responsible for verifying the stakes and awarding players.
On Base Mainnet, the contract resides .
