zkLink Nova is the industry’s first aggregated Layer 3 zkEVM Rollup network, built on top of Ethereum and Ethereum Layer 2 rollups (L2s). zkLink Nova is an EVM-compatible, open platform designed for the simple and fast development of any kind of smart contract. It allows scattered assets across Ethereum Layer 2s to be aggregated for interoperable transactions, secured by zero-knowledge proof technology, with extremely low gas costs, fast finality, and Ethereum’s security.
Key Features of zkLink Nova
Supporting Universal dApps
zkLink Nova supports the development of all DApps through smart contracts. To facilitate developer migration to zkLink Nova, it aims to be EVM-compatible by utilizing the ZK Stack, ensuring that all contracts and tools that work on Ethereum and Ethereum Layer 2s also work on zkLink Nova with minimal modifications. Developers can easily reuse existing functionalities.
Native Asset Aggregation
Users can deposit assets from Ethereum’s Layer 1 and Ethereum Layer 2s directly to zkLink Nova. These assets are locked on the source chains and enter the zkLink Nova network via a canonical rollup bridge, allowing applications on Nova to access all connected Layer 2s’ native tokens. Tokens of the same kind, but from different rollups, will merge into the same token on zkLink Nova’s Layer 3, fostering unified liquidity.
Chain Abstraction
Nova’s native Account Abstraction (AA) enables multi-chain smart accounts, facilitating user interactions with DApps on connected blockchain networks through a unified interface. Users can see their aggregated assets across multiple chains and seamlessly use assets on one chain for transactions on another, with fillers in the solver network fulfilling cross-chain transactions at low cost.
Low Fee and High Scalability
zkLink Nova’s modular stack provides unparalleled scalability for dApps. The ZK Stack, used as the execution layer, dramatically reduces execution costs and enhances user experience. In Validium mode, an external DA solution further reduces transaction costs for end users.
Ethereum Equivalent Security
zkLink Nova achieves Ethereum-grade security by verifying every transaction with zero-knowledge proofs. The zkLink Nexus’s multi-chain state synchronization mechanism prevents deposit fraud in cross-chain asset transfers, inheriting the security of Ethereum.
