Mongambit

MonGambit is a chess-vs-Stockfish challenge platform on Monad: deposit 1 MON, play a 5+1 blitz game against Stockfish at max skill, and win 10 MON from a shared prize pool if you checkmate it. We built a full playable browser demo plus a working Web3 vertical slice — a deployed Monad testnet contract, a Node/PostgreSQL/native-Stockfish match service, and EIP-712 signed result verification — proving out deposit → authoritative game → signed payout end-to-end.
