Matter Labs plans to stop using ZKsync Lite, the first iteration of its Layer 2 Ethereum network, the team said in a post on X over the weekend.
The company framed the move, which took place in early 2026, as a planned sunset for an early proof of concept that helped validate its zero-knowledge cumulative design options before newer systems went live.
ZKsync Lite, which debuted in 2020, was built for basic token transfers, but took a backseat after the 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 now, funds will remain secure and withdrawals to the Ethereum mainnet will still be available, the team said. A detailed migration plan and timeline for closure will be published next year.
“ZKsync Lite was an innovative proof of concept and validated critical ideas related to building production ZK systems. It did its job: demonstrate what is possible and pave the way for the next generation,” the team wrote in X.
