Decentralized exchange Merlin, which uses zkSync, has reportedly been hacked for more than $1.82 million immediately after receiving a code audit from smart-contract auditor Certik. Certik is investigating the incident, and its initial findings suggest a potential issue with private key management rather than a code exploit. The company said that while audits cannot prevent private key issues, it always highlights best practices for projects. Merlin has not yet commented on the matter. (TheBlock)
