According to BlockchainReporter, ZKsync developer Matter Labs announced a security-hardening program for chains running the EraVM execution environment before its retirement within six months. Ordinary externally owned accounts require no action, while smart contract asset steps will be published soon.

Matter Labs outlined five security measures. First, public EraVM chains are recommended to raise execution delay from three hours to 24 hours. Second, teams are working with active chains to run an independent second node confirming each executed batch. Third, covered Era protocol code will be published three months after an upgrade ships instead of immediately. Fourth, GAP-5 renames Emergency Upgrades to Instant Upgrades, requiring forum notices. Fifth, EraBender is being developed to run alongside Boojum.

EraVM is retiring because artificial intelligence changed the threat landscape. Its successor, the Atlas upgrade, runs EVM natively. EraVM chains continue settling value through the transition, but new protocol capabilities will ship on Atlas. Permissioned chains like GRVT will communicate steps directly, and the retirement does not affect chains already running Atlas.
