ZKsync to Decommission ZKsync Lite on May 4, 2026; Era and ZK Stack Unaffected

ZKsync announced it will decommission ZKsync Lite (formerly ZKsync 1) on May 4, 2026, saying Matter Labs stopped development on Lite in March 2023 after launching Era, ChainCatcher reported. At shutdown, the network will halt block production and permanently freeze its final state so account balances cannot change, and the decision does not affect ZKsync Era or other chains built on ZK Stack. The team will maintain read-only APIs for at least one year to support historical data queries and recommends users withdraw assets before the deadline, noting unwithdrawn funds can still be claimed afterward. Around $33.9 million is currently bridged to ZKsync Lite, including about $24.9 million in stablecoins, $8.4 million in ETH and its derivatives, $313,000 in BTC and its derivatives, and roughly $231,000 in other assets, ChainCatcher reported; launched in June 2020 as Ethereum's first zero-knowledge Rollup, ZKsync Lite supported token transfers, atomic swaps and NFT minting but did not support smart contracts.
