Clawpay

A non-custodial payment wallet for MCP agents that lets Claude execute x402 and Stripe MPP transactions across 17 chains with hard spend caps and human approval gates. You get on-chain budget enforcement via smart contracts, per-transaction limits, daily aggregate caps, and a full audit trail of every payment attempt. Built on viem with zero Python dependencies. If you're running agents that hit HTTP 402 endpoints or need to enforce cost governance across paid API calls, this gives you the policy layer that the MCP spec doesn't provide. Already integrated into NVIDIA's NeMo Agent Toolkit Examples for production agent workflows that involve actual money movement.
