Aztec Connect is being investigated for a potential exploit after about $2.1 million moved from the protocol’s old Ethereum smart contract on June 14. The affected system is Aztec Connect, a deprecated privacy product that is separate from the AZTEC ERC20 token and the current Aztec Network. The Aztec Foundation said there are no links between the old product and any smart contracts tied to the AZTEC token or current Aztec network infrastructure.
