Aztec Bridge Smart Contract Vulnerability: $2.16M Reported Loss

·Historical incident record

Incident Overview

On June 17, 2026, attackers exploited Aztec’s deprecated Private Rollup Bridge (launched in 2021 and shut down in 2022). They abused an immutable escape-hatch function that lacked proper ownership checks, using manipulated or fake rollup proofs to withdraw assets without corresponding deposits. Approximately $2.16 million (1,158 ETH, 150,000 DAI, and 0.47 renBTC) was drained. Aztec Labs confirmed the affected contract is unrelated to the current Aztec Network or the AZTEC ERC-20 token and that they have no control over the immutable old contracts.
