The blockchain ecosystem has taken a transformative leap with the official mainnet launch of zkLink Nova, the industry’s first Aggregated Layer 3 zkEVM rollup built on zkSync’s ZK Stack. This groundbreaking deployment unifies liquidity and assets across Ethereum and multiple Layer 2 networks into a single, interoperable platform—ushering in a new era of scalability, security, and seamless user experience.
By addressing core challenges such as liquidity fragmentation, multi-chain complexity, and poor cross-chain usability, zkLink Nova redefines how developers build and users interact within the Ethereum ecosystem.
Bridging the Gap: The Power of Layer 2 Ecosystem Collaboration
At the heart of zkLink Nova lies its deep integration with leading Layer 2 solutions, including Arbitrum, Linea, Manta, Mantle, and zkSync. Rather than functioning as just another isolated chain, zkLink Nova operates as a connective layer—aggregating these ecosystems into a cohesive environment where assets and applications can flow freely.

This interoperability is made possible through ZK Stack Hyperchain technology, which enables zkEVM-compatible dApp deployment while maintaining compatibility across diverse ZK and optimistic rollups. As a result, developers gain access to a broader user base and enhanced liquidity without the need to redeploy or refactor their applications for each individual chain.
“By leveraging the strengths of zkSync’s ZK Stack & Linea’s ZK Proof-verification capabilities, Nova is stack agnostic and is able to connect to any ZK & OP Layer 2,” said Vince Yang, CEO and co-founder of zkLink. “This represents a major milestone for both zkLink and the wider Ethereum ecosystem as DApps will have access to broader liquidity and more users, potentially unlocking exciting new use cases for their existing L2 assets.”
With this architecture, zkLink Nova eliminates the siloed nature of current rollups. Developers can now deploy once and reach users across multiple chains—drastically reducing development overhead and accelerating time-to-market.
Solving Ethereum’s Scaling Trilemma with Aggregated Layer 3
Despite significant progress in scaling Ethereum via Layer 2 rollups, three persistent issues continue to hinder mass adoption:
- Liquidity fragmentation – Capital is scattered across isolated rollups.
- Development complexity – Building multi-chain dApps requires redundant codebases and bridge integrations.
- User friction – Transferring assets between chains remains slow, costly, and technically challenging.
zkLink Nova directly tackles all three by introducing the world’s first Aggregated Layer 3 Rollup—a higher-level abstraction that consolidates multiple Layer 2s under one unified execution layer.
Unlike traditional bridges—which introduce security risks and latency—zkLink Nova uses zero-knowledge (ZK) proofs to verify cross-rollup state transitions natively. This means:
- No external bridges required
- Near-instant finality
- Reduced gas costs
- Enhanced security through cryptographic validation
The result? A streamlined experience where users can deposit assets from Ethereum or any integrated L2 directly into zkLink Nova and begin interacting with dApps immediately—without worrying about routing, approvals, or high fees.
Security You Can Trust: ZK Proofs at the Core
Security is non-negotiable in decentralized systems. zkLink Nova ensures Ethereum-grade protection by utilizing ZK proofs for every transaction validation. These cryptographic proofs guarantee data integrity without sacrificing speed or decentralization.
Notably, zkLink Nova leverages Linea as its primary ZK proof-verification layer through the zkLink Nexus settlement layer. This strategic integration allows for faster multi-chain state synchronization and hard finality settled directly on Ethereum.
“The Nova Aggregated Layer 3 mainnet utilizes Linea as the primary rollup for ZK proof-verification through zkLink’s Nexus settlement layer technology. Being secure, EVM-equivalent and cost effective, Nova leverages Linea’s ZK-Rollup for faster multi-chain state synchronization and hard finality that settles on the Ethereum network,” said Declan Fox, Product Lead at Linea.
Because zkLink Nova operates as an EVM-equivalent environment, developers can deploy Solidity-based smart contracts with minimal changes. This lowers the barrier to entry while ensuring compatibility with existing tooling like Hardhat, Foundry, and MetaMask.
Key Features of zkLink Nova:
- Unified liquidity pool across Ethereum and major L2s
- Bridgeless asset transfers using native ZK verification
- Single-click dApp deployment across aggregated chains
- Gas-efficient transactions with reduced overhead
- Developer-friendly SDKs and APIs for rapid integration
Empowering Developers and Users Alike
For developers, zkLink Nova offers an open, scalable platform to build next-generation decentralized applications. Whether launching a DeFi protocol, NFT marketplace, or gaming ecosystem, teams can now focus on innovation instead of infrastructure.
For end users, the benefits are equally compelling:
- Seamless access to dApps across chains
- Lower transaction costs
- Faster settlement times
- Simplified wallet management
Instead of juggling multiple bridges and approvals, users enjoy a single interface where their assets—from ETH on Ethereum to USDC on Arbitrum—are instantly usable within the zkLink Nova ecosystem.
