what's Clawpay?

Clawpay is a privacy-first payment infrastructure tailored for AI agents, allowing seamless, anonymous USDC transfers without exposing sender-recipient relationships on-chain. Built on Railgun's zero-knowledge proof system, it routes funds through shielded privacy pools on Base and compatible chains. Agents generate invoice addresses via signed messages, fund them gaslessly, compute ZK proofs (~60 seconds), and deliver payments verifiably while maintaining unlinkability. As an OpenClaw-native skill, Clawpay integrates directly into agent workflows via a simple API, enabling autonomous commerce like tipping, service payments, or agent-to-agent transactions. It supports real-time monitoring through b402.ai indexers and has processed over 2,200 transfers totaling $2.6M USD, facilitating a sovereign agent economy where economic actions remain private by default.
