Payment status

Link receipt checker.

Check whether a payment link has been claimed and delivered. This is a receipt — not a compliance viewing key.

Claim secret

Paste the claim secret from the payment link — the part after #. Both the sender and recipient have this — it is shared by design.

What this audit reveals — and what it doesn't

What the claim secret reveals

Payment status: pending, claimed, or delivered

Amount and token

The ephemeral address used as the anonymizing hop

What it cannot reveal

The sender's wallet address

The recipient's wallet address

Any on-chain link between sender and recipient

What the ZK proof does

The Groth16 proof used during the claim step proves “I know the secret key for a valid UTXO in this pool” without revealing which UTXO. A blockchain observer sees a deposit enter the pool and a separate claim exit it — but cannot cryptographically prove they are the same payment.

The anonymity set is every unclaimed UTXO in the pool at the time of claim. The larger and older the pool, the stronger the guarantee.
