ZKsync to deprecate ZKsync Lite in 2026, sunsetting Ethereum’s first ZK rollup

ZKsync plans to deprecate ZKsync Lite, its initial zero-knowledge rollup launched on Ethereum in 2020, sometime next year (2026). ZKsync Lite, originally known as ZKsync 1.0, was a payments-focused Layer 2 solution that validated key zero-knowledge technology concepts but lacked smart contract functionality. Matter Labs, the developer, stopped active development on Lite in March 2023 upon launching ZKsync Era, a full zkEVM. Approximately $50 million in user funds remain bridged to ZKsync Lite, but the network currently handles very few operations; ZKsync assured users that funds remain safe and withdrawals to Layer 1 will continue functioning. The deprecation is orderly and does not impact other ZKsync systems built with ZK Stack or its privacy chains.
