ZKsync’s original layer 2 network, zkSync Lite, is being fully wound down, with remaining support and infrastructure slated to end in 2026.

zkSync Lite is a user‑focused zk‑rollup from Matter Labs that went live on the Ethereum mainnet as one of the earliest zero‑knowledge rollups.

It was initially optimized for simple payments, swaps, and NFT transfers rather than full smart‑contract support. Its successor, zkSync Era, added Ethereum Virtual Machine (EVM) compatibility and broader decentralized‑application functionality.

Matter Labs effectively stopped active development on zkSync Lite once zkSync Era became the flagship network, and by 2024 several ecosystem participants were already treating Lite as deprecated.

“This is a planned, orderly sunset for a system that has served its purpose and does not affect any other ZKsync systems,” said the ZKSync team in a post on X.

Around $50 million in user funds remains bridged to zkSync Lite, with concrete details around dates for the migration yet to be shared.
