New Fraud Surface

  • • Prompt injection turns merchant content into commands
  • • Delegated payment credentials are a prime target
  • • Bugs and hallucination exceed the buyer's real intent

Gates, Not Guesses

  • • Verify agent identity and delegation scope first
  • • Detect injection before tools spend money
  • • High-risk actions step up to a human

The Chain Is Evidence

  • • Each step signs a verifiable credential
  • • Disputes resolve against what was authorized
  • • Liability follows the signature, not the story
