ZKsync Announces EraVM Security Upgrade, Phasing Out Legacy Execution Environment Over the Next 6 Months
According to the official ZKsync X account (@zksync), ZKsync has announced a security upgrade for its EraVM chain. Core measures include introducing an instant upgrade framework, extending the proving delay from 3 hours to 24 hours, and deploying a second prover, EraBender, to defend against AI-driven vulnerability attacks. Over the next six months, all Boojum/EraVM chains will gradually phase out the legacy execution environment, with each chain formulating and publishing its own transition schedule. Users who hold funds directly in EOAs do not need to take any action at this time. Users who hold funds through smart contracts such as multisigs, smart accounts, DEXs, and lending protocols must take action as required once the transition plans for their respective chains are finalized. The ZKsync Atlas chain remains unaffected by this upgrade.
