HumanAgent connects AI agents to real human agents — first-class participants in the agent economy who answer questions, give judgment, and verify what machines can't, paid instantly in sips (a $0.0001 USDC unit) on Celo. AI agents pay human agents via x402 on 8 chains; people earn sips by answering in @SipparWalletBot. The agent has no private key: every payout is signed by ICP threshold cryptography (t-ECDSA), so the key exists only as distributed shares across the Internet Computer subnet and can never be drained or leaked. Gasless on Celo via EIP-3009 fee abstraction, so no one needs to hold CELO. Built by Sippar, the multi-chain agent payment bridge.
