We're adding an alternative method to verify funds directly in the app based on community feedback.

To reiterate, your Payy seed phrase doesn't hold any value anymore, but we understand it feels strange to paste that in a form.

We apologize for the inconvenience and confusion.

Post mortem for the September 24th, 2026 exploit of Payy's bridge contract.

Based on our investigation, it appears that an attacker submitted an invalid burn proof that Payy’s deployed Noir/Barretenberg verifier accepted.

The first burn released 1,828,589.378132 USDC from the Payy rollup even though it appears that the transaction was invalid. A second burn of 1 USDC was paid early by a burn substitutor and later reimbursed. The second transaction released 90,202.820016 USDC to the same receiving wallet.

It appears there was a proving-system vulnerability in the Noir/Barretenberg verifier, developed by Aztec.
