TruCheq Protocol

Security checks for vulnerabilities and agentic risk

Overview

The skill matches a P2P marketplace purpose, but it handles identity proofs, messages, uploads, and payments through an unrestricted configured API endpoint with limited safety warnings.

Review this carefully before installing. Only use a trusted HTTPS TRUCHEQ_API_URL, confirm where identity proofs, images, messages, wallet addresses, and payment data will be sent, and independently verify listing details, seller address, chain, token, amount, and refund expectations before paying.

Finding

The purchase flow instructs users to pay sellers directly via x402 while only briefly noting elsewhere that there is no escrow, but it does not prominently warn that payments are irreversible and may not provide buyer protection. In a P2P marketplace with direct seller payments, this omission can mislead users into treating the flow as safer than it is, increasing fraud and loss risk.
