Use the rail they already have. Make the proof repeatable.

The wrapper formats the payee, memo, amount hint, expiration, and ProofRail Seal so a buyer can pay from their own bank or Zelle app without the site touching funds.

Why this is easier

Instead of asking a buyer to understand a new payment system, ProofRail gives them one clean instruction set for the rail they already use. The seller gets a stable reference, the buyer gets a packet, and both sides can verify what was supposed to happen.

  • One memo.The payment reference is generated before the buyer opens their bank app.
  • One packet.The downloaded JSON records the route, boundary, amount hint, and seal.
  • One reconciliation path.Reported payment is logged separately from final settlement.
