Matter Labs plans to deprecate ZKsync Lite, the first iteration of its layer 2 Ethereum network, the team said in a post on X over the weekend.
The company presented this move, which took place in early 2026, as a planned sunset for an early proof of concept that helped validate its zero-knowledge rollup design choices before fielding new systems.
ZKsync Lite, which debuted in 2020, was designed for basic token transfers, but took a backseat after developers released ZKsync Era in March 2023, a more advanced zkEVM rollup, which now anchors the project’s broader ZK Stack roadmap.
The Lite network will continue to operate for the time being, with funds remaining secure and withdrawals to the Ethereum mainnet still available, the team said. A detailed migration plan and closure schedule will be published next year.
“ZKsync Lite was a groundbreaking proof of concept and validated critical ideas related to building production ZK systems. It did its job: proving what is possible and paving the way for the next generation,” the team wrote on X.
