[ZKsync Announces EraVM Security Upgrade, Phasing Out Old Execution Environment Over the Next 6 Months] ZKsync has announced a security upgrade for EraVM, including measures such as introducing an instant upgrade framework, extending execution delays to 24 hours, and developing a second prover, EraBender. Over the next 6 months, all Boojum/EraVM chains will gradually phase out the old execution environment, with each chain setting its own transition timeline. Users holding funds directly via EOA do not need to take any action for now; users holding funds through multi-signature wallets, smart accounts, DEXs, lending protocols, or other smart contracts will need to follow the requirements once the transition plans for each chain are finalized. The ZKsync Atlas chain is not affected by this upgrade.
