SlowMist Technology founder, Yu Xian, recently revealed an incident involving the leak of the private key of the DAI (Debt-Adjusted AI) L2 deployer. This leak led to some DAI contract addresses deployed on the Optimism and Arbitrum blockchain platforms in recent times becoming "honeypots"—addresses that appear secure but are actually traps designed by attackers. These honeypot addresses do not show obvious risk signs on certain platforms; however, they reveal security vulnerabilities in the Base and Polygon networks. Fortunately, the mainnet DAI contracts were not affected by this incident and maintained their original security. However, this event serves as a reminder for users to remain highly vigilant when using DAI and its derivative services, especially during cross-chain interactions or when using services deployed on non-mainnet networks, to avoid falling into such traps.
