Recorded demo · No new paymentsSaved evidence. No wallet connection or live AI calls.

A PAYMENT STORY, WITH RECEIPTS · BUILT ON NEAR

Two signed bills.
One payment.

Same supplier. Same service week. The worker crashes and both bills are retried. The merchant still gets paid once.

Your agent proposes. Your vault enforces.

02 / THE RECEIPT BOOK

Nothing to take on trust.

Two separate recordings.
The original evidence for each.

Local test chain

The weekly crash & retry

Two signed bills for the same enrolled week. One settled attempt. The worker was killed after settlement, then both bills were retried.

This recording uses disposable local test NEAR. It has no public explorer transaction.

A separate café run

Valid payment, tampered payee, duplicate bill, budget rejection, and crash after reservation. These are historical testnet transactions.

Evidence provenance & scope

Recorded proposals used fixtures: zero live model calls. This page reads committed public records; it does not connect to a vault, submit transactions, or call an AI model. Supplier signatures authenticate bills; they do not prove service delivery.

    03 / REPRODUCE IT

    Run the real test yourself.

    After the repository’s local setup, reproduce the vault upgrade, weekly bill race, worker crash and retry with disposable test funds.
