Utility guide
Model external-payment evidence without enabling settlement.
PREP-4 is an experimental, non-reliance profile for synthetic fixtures and compatibility research. Production x402-XRPL settlement is disabled.
When to use this
- • An agent or buyer pays for an API, MCP, data, or tool result using x402-XRPL.
- • The resource operator needs proof of what was requested, paid for, delivered, and replay-checked.
- • A reviewer needs public-safe hashes instead of wallet keys, raw prompts, private paid data, or logs.

ProofRelay verifies internal evidence consistency, receipt ordering, payment or entitlement context, hash-chain continuity, and replay behavior for submitted non-confidential bundles.
ProofRelay does not process payments, custody funds, settle x402 charges, certify legal/title status, verify real-world truth, review source code, or certify model safety.
This profile does not move value or prove settlement. Production x402-XRPL is disabled; ProofRelay is not a wallet, custodian, facilitator, payment processor, escrow agent, or legal-truth oracle.
