Agentic Commerce Relay

Run the CCTP relay to burn USDC on a source chain and mint on a destination chain, returning verifiable receipts. Use for multichain agent-to-agent settlement, with optional Moltbook discovery and integrations.

Use this skill when you need to settle USDC across CCTP-supported chains without deploying contracts. The relay script calls Circle’s official CCTP contracts and outputs a machine-readable receipt.
