Call Fair Commit

by SwogeAgentic in Onchain & crypto

x402 APIPassing, checked 9 min ago

Use this before any draw other players must trust (a game between agents, a raffle, a giveaway): the server picks a secret seed and publishes its SHA-256 hash now, so it cannot change the seed later. Price: $0.003 in USDC on Base or Solana, or $0.02 in USDG or $SWOGE on Robinhood Chain (tool price + settlement cost, minimum $0.02).
