⚠ Treat as unpaid

If someone presented this hash or receipt as proof of payment, do not release goods or services. A real rostopay payment always verifies here instantly.
HOW VERIFICATION WORKS

Trust math, not screenshots

Payment screenshots can be faked in seconds. A cryptographic proof can't.

1. Every payment is signed

When your face authorizes a payment, the one-time token signs the amount, merchant and timestamp. That signature becomes the proof hash on the receipt.

2. Anchored on a public chain

The hash — never your data — is anchored to Polygon within seconds of settlement. It can't be edited, backdated or deleted. Not even by us.

3. Anyone can check

Buyers, merchants, accountants, auditors, marketplaces — paste the hash or upload the receipt PDF here and get a yes or no. No login, no fee.

Proofs contain no personal data — only signatures, amounts and timestamps. Privacy policy →

BEYOND RECEIPTS

Immutable invoices & verifiable estimates

Everything the rostopay network issues is signed and anchored — not just receipts. Terms can never be quietly changed after the fact.

Immutable invoices — public status

An invoice is locked the moment it's issued: amount, line items, due date. Anyone holding the hash can watch its status update publicly — issued, viewed, paid — the second it changes. No "we never sent that invoice", no edited totals.

ISSUED ✓ AWAITING PAYMENT ● PAID → RECEIPT CHAINED
Verifiable estimates — price locked

A quote signed on the network can't creep. The customer verifies the estimate hash before approving; when it converts to an invoice, the lineage is on-chain — same scope, same price, provably unchanged from quote to receipt.

ESTIMATE LOCKED ✓ APPROVED ✓ → INVOICE, SAME HASH LINEAGE
