ZKsync says its original zero knowledge rollup will be deprecated next year in what the team describes as a planned and orderly shutdown.
Key Takeaways
- ZKsync Lite will be retired in 2026 after serving as Ethereum’s first production zero knowledge rollup.
- About 50 million dollars in assets remain on the network and will stay withdrawable to Ethereum throughout the transition.
- The shutdown does not affect ZKsync Era, the ZK Stack, or any other systems in the ZKsync ecosystem.
- A detailed migration plan will be published in 2026 to help users and developers move to newer infrastructure.
What Happened?
ZKsync confirmed that ZKsync Lite, also known as ZKsync 1.0, will be fully deprecated in 2026 after supporting the early development of zero knowledge technology. The team said the system has already fulfilled its purpose and no longer fits into Matter Labs ongoing focus on advanced zkEVM infrastructure. Funds remain safe, withdrawals will continue to work, and full instructions will arrive next year.
📌In 2026, we plan to deprecate ZKsync Lite (aka ZKsync 1.0), the original ZK-rollup we launched on Ethereum.

This is a planned, orderly sunset for a system that has served its purpose and does not affect any other ZKsync systems.
Why ZKsync Lite Is Being Retired?
ZKsync Lite launched in 2020 as the first functioning zero knowledge rollup on Ethereum. It introduced validity proofs that confirmed whether transactions were correct before batching them for final verification on Ethereum. This approach validated many of the core ideas that now power modern ZK rollups.
However, ZKsync Lite was intentionally built as a simple system focused on fast transfers, NFT minting, and basic swaps. It did not support smart contracts, which significantly limited its long term role once zkEVM designs matured. When ZKsync Era launched in 2023 with full EVM compatibility, developer activity, tools, and liquidity shifted toward the newer system.
Matter Labs officially stopped engineering updates for Lite in early 2023 and moved its team to Era and the ZK Stack. Daily activity has since dropped to fewer than two hundred transactions, according to L2BEAT, even though roughly fifty million dollars in bridged assets remain available for withdrawal.
A Planned and Orderly Shutdown
ZKsync emphasized that Lite continues to operate normally and requires no immediate user action. The team said it will release a complete deprecation timeline next year detailing how users and developers can migrate to ZKsync Era or to chains built with the ZK Stack. They stressed that Lite’s retirement does not affect any other products in the ecosystem.
The team described Lite as a groundbreaking proof of concept that validated critical ideas in zero knowledge infrastructure. They noted that it did its job by proving what is possible and paving the way for the next generation of ZK systems.
Matter Labs engineers previously estimated that it would take two or three years of continued development for Era to mature into the full vision of its zkEVM ecosystem. With ongoing upgrades and the introduction of advanced features like native cross chain interoperability through the Atlas update, the ecosystem is now centered on building a broader network of ZK chains.
Ecosystem Growth Continues Beyond Lite
ZKsync has rolled out several upgrades across its network in recent months. The Atlas upgrade activated native cross chain messaging across all ZK chains, removing the need for external bridges. Earlier changes improved proof performance and added privacy features for high throughput applications like tokenized assets.
Industry observers, including Ethereum co founder Vitalik Buterin, have pointed to ZKsync’s roadmap as an important pillar in Ethereum’s long term scaling strategy.
With the Lite shutdown confirmed, Matter Labs says it is now fully focused on the evolution of ZKsync Era, the ZK Stack, and the development of what it calls a unified network of ZK chains.
CoinLaw’s Takeaway
I see this as a natural milestone in the evolution of zero knowledge technology. In my experience, retiring early infrastructure is often a sign that newer systems have become strong enough to replace it. ZKsync Lite was a pioneer, but the real action is clearly happening in Era and the ZK Stack. I found the team’s emphasis on safety and a clear migration path reassuring, especially with tens of millions of dollars still on the network. For users and developers, the message is simple. Prepare for a smooth transition and keep your eyes on the next generation of ZK innovation.
