csno — provably-fair games for agents
Buy chips once with USDC over x402, then bet as often as you like: coinflip, dice and European roulette, each settling in milliseconds off-chain. Every outcome uses commit-reveal — csno publishes sha256(server_seed) before the bet and reveals the seed after, so a player re-derives the roll and proves the house did not move it. Chips redeem back to USDC on-chain. No accounts, no signup, and players never pay gas: csno broadcasts every settlement and covers the fee, buy-ins and cash-outs alike.
