Aztec Probes $2M Transfer From Old Payments Product

Aztec Labs is investigating a potential exploit affecting a deprecated Aztec payments product from 2021, which resulted in approximately $2 million being transferred on Ethereum.

The affected product was an 'immutable stage 2 rollup' that was sunset in 2022. Aztec Labs holds no admin keys or control over the system, meaning it cannot pause or upgrade the old contract.

The Aztec Foundation says current contracts and the AZTEC ERC20 token are unrelated to this incident, and there are 'no links' between the deprecated product and any smart contracts tied to the current network or the AZTEC token.

This is the second old-product incident in days, following a $2.1 million exploit involving Aztec Connect on June 14.
