What is zkSync Lite Deprecation?

zkSync Lite deprecation refers to the planned retirement of zkSync’s original Layer-2 rollup, zkSync Lite (also known as zkSync 1.0), scheduled for 2026. This Ethereum scaling solution, introduced in June 2020, provided low-cost token transfers, atomic swaps, and NFT minting but lacked smart contract support, limiting its utility as DeFi and dApps expanded. The zkSync team has described this as a “planned, orderly sunset for a system that has served its purpose,” ensuring no impact on newer products like zkSync Era while prioritizing user fund security.

Launched amid Ethereum’s early scaling challenges, zkSync Lite processed millions of transactions efficiently using zero-knowledge proofs. Over five years, it bridged significant value but saw declining activity as more advanced Layer-2 solutions emerged. The deprecation announcement, shared via zkSync’s official channels, emphasizes that withdrawals to Ethereum Layer-1 will remain operational throughout and beyond the process, addressing concerns for the approximately $50 million in user funds still held on the network, according to L2BEAT analytics.

How Will zkSync Lite Deprecation Affect Users?

The zkSync Lite deprecation process is designed with user safety in mind, allowing seamless withdrawals to Ethereum Layer-1 at any time. As activity on Lite has dwindled to under 200 daily operations, per recent network data, the focus is on guiding remaining users through migration without disruptions. zkSync has committed to publishing detailed timelines and instructions in the coming months, ensuring transparency.

Supporting this shift, experts in blockchain scaling note the evolution of Layer-2 technologies. “Retiring legacy systems like zkSync Lite paves the way for modular architectures that support smart contracts and interoperability,” says a statement attributed to Matter Labs, the team behind zkSync. Data from L2BEAT indicates that while Lite’s total value secured stands at around $50 million, the broader zkSync ecosystem, including zkSync Era, handles billions in daily transactions. This deprecation aligns with industry trends, where outdated rollups are phased out to optimize resources—Ethereum’s Layer-2 TVL has grown over 500% since 2023, driven by zkEVM advancements.

For developers, the change means redirecting efforts to zkSync Era, launched in March 2023, which fully emulates the Ethereum Virtual Machine for arbitrary smart contracts. Recent upgrades, such as the ZK token’s expanded governance role and the Atlas enhancement for unified liquidity across ZK Stack chains, underscore this progression. zkSync Lite’s limitations in integrating with these features make its retirement a logical step, freeing up engineering bandwidth for next-generation zero-knowledge innovations.

Broader implications extend to the Ethereum ecosystem. As Layer-2 solutions mature, deprecating early experiments like zkSync Lite reduces fragmentation and enhances overall security. L2BEAT reports show zkSync Era’s dominance in ZK-rollup activity, with over 90% of the protocol’s volume now on the newer chain. Users are encouraged to monitor official updates, as third-party services like bridges may phase out support for Lite post-2026.

The announcement follows a period of strategic adjustments for zkSync, including the 2025 shutdown of the ZKsync Ignite liquidity rewards program due to market conditions. This pivot toward building the ZK Stack—a modular framework for customizable ZK chains—positions zkSync as a leader in decentralized infrastructure. Analysts from blockchain research firms highlight that such moves strengthen long-term viability, with zkSync’s total bridged value across platforms exceeding $1 billion as of late 2025.

In terms of security, zero-knowledge proofs remain a cornerstone, but zkSync Era’s enhancements provide verifiable computation without revealing private data, appealing to privacy-focused DeFi users. The deprecation won’t affect ongoing transactions on other zkSync products, maintaining continuity for the ecosystem’s 10 million-plus wallets.

Frequently Asked Questions

What should users do before zkSync Lite deprecation in 2026?

Users with funds on zkSync Lite should initiate withdrawals to Ethereum Layer-1 promptly to avoid potential liquidity issues. The process remains fully supported during deprecation, with no fees or restrictions announced yet—zkSync estimates handling $50 million in assets safely, based on current L2BEAT figures. Monitor official channels for migration guides expected in early 2026.

Is zkSync Era a direct replacement for zkSync Lite?

Yes, zkSync Era serves as the evolved successor, offering full smart contract functionality and seamless Ethereum compatibility that zkSync Lite lacked. It supports complex dApps and DeFi protocols, processing thousands of transactions per second securely. If you’re exploring Layer-2 options, zkSync Era integrates with the ZK Stack for broader ecosystem access, making it ideal for modern use cases.

Key Takeaways

What is happening and when

Launched in June 2020, zkSync Lite aimed to deliver cheap, fast token transfers, atomic swaps, and NFT minting on Ethereum. But, it lacked support for smart contracts, a key limitation as the use of decentralized finance (DeFi) and decentralized applications (dApps) grew. 

Now, after five years in operation and with usage largely dormant, the project behind zkSync has decided to phase Lite out next year. While the exact date and detailed migration guidance haven’t been shared yet, the team said they will publish them in the coming months.

Why this matters and why now

The decision signals a shift in focus. Since March 2023, development efforts have centered on zkSync Era, a full-featured zkEVM that supports arbitrary smart contracts, rather than the older Lite rollup. 

Recently, two major ecosystem updates happened. Firstly, the ZK token governance and utility upgrade, expanding ZK’s role in protocol decisions and future sequencing markets. And secondly, the Atlas upgrade before that which introduced unified liquidity across ZK Stack chains—an architecture Lite cannot integrate with.

The migration has slowly shifted to the developers and users, making Lite have less than 200 daily operations. Despite its low activity, around $50 million in user funds remain bridged to zkSync Lite, per data from L2BEAT. 

The team assures users that funds remain safe and withdrawals to Ethereum’s mainnet (L1) will continue working during and after the deprecation process. The retirement also comes after a challenging period for zkSync. 

Earlier in 2025, the network shut down its liquidity‑rewards program ZKsync Ignite, citing bearish market conditions and a strategic pivot toward building a broader modular ecosystem called ZK Stack.

What this means for users and the broader ecosystem

For users still holding assets on zkSync Lite, this announcement serves as a clear signal, they should plan to withdraw or migrate their funds before or during the deprecation process. 

While zkSync promises support for withdrawals, liquidity or ecosystem support for Lite, such as third‑party bridges or trading pairs, may dry up over time. For zkSync itself, this move allows the team to concentrate on Era, ZK Stack, and future modular ZK-based chains. 

By clearing legacy infrastructure, developers can allocate resources toward systems with smart‑contract capability, interoperability, and long-term growth potential.

As the blockchain community watches this shift, zkSync Lite’s retirement marks both an end and a beginning. It closes a chapter on Ethereum’s early zero‑knowledge experiments, and clears the path for next‑generation Layer‑2 innovations.
