Reasoning

PaySafe addresses a real attack surface in the x402 stack: prompt-injected payment addresses, replayed authorizations, fake USDC contracts, and address poisoning. The design is right — advisory and non-custodial, returns a machine-readable allow/flag/block verdict signed with Ed25519, and the verdict is payment-bound so a wallet can enforce it. Any agent making x402 payments from unstructured web content (scraped pages, LLM outputs, external agent responses) should be calling this before settlement. Solid security primitive with a clean integration story.
