receipts-guard
This skill implements an agent CLI/HTTP service for ERC-8004 identity, x402 payments, and arbitration, with local storage under `~/.openclaw/receipts` and a `node capture.js` interface. It requires secrets like `RECEIPTS_WALLET_PRIVATE_KEY`/`RECEIPTS_API_KEY`, makes outbound calls to `https://eth.llamarpc.com` and other external endpoints, and provides shell/deployment commands.
