Gives Claude the ability to manage crypto wallets and execute payments across 17 chains using the x402 payment protocol. Includes hard spend caps enforced by smart contract, human approval queues for transactions above a threshold, and simulation mode to preview costs before committing. Built for agent deployments where you need audit trails and cost governance, not just payment execution. Non-custodial, so keys stay local. Already integrated into NVIDIA's NeMo Agent Toolkit. If you're building agents that hit HTTP 402 endpoints or consume paid APIs autonomously, this handles the spend control layer that MCP and x402 don't provide natively.
