Aztec Connect's deprecated RollupProcessorV3 contract was drained of ~$2.1M (909 ETH) via a ZK proof-verification flaw. Aztec Labs holds no admin keys and cannot intervene.

The abandoned DeFi platform Aztec Connect lost about $2.1 million in an exploit, with Aztec Labs saying it has no control over the deprecated smart contracts.

Aztec Connect's deprecated smart contract was exploited for over $2M in ETH, DAI, and wstETH three years after the zk-rollup bridge shut down on Ethereum.
