ZkLink Nova Launches as a Layer 3 Blockchain, Unifying Liquidity Across Layer 2s

ZkLink Nova aims to solve the liquidity fragmentation issue by aggregating liquidity across five layer 2 blockchains, providing a unified ecosystem for users and DApps.

Ethereum’s popularity has been driven by its layer 2 blockchains, which offer faster and cheaper transactions compared to the main Ethereum network. However, the liquidity across these layer 2 blockchains has been fragmented, making it difficult for users to access a larger pool of assets. In response, ZkLink Nova, a layer 3 blockchain, has launched with the goal of aggregating liquidity across five layer 2 blockchains. This move aims to provide a unified ecosystem and deeper liquidity for users and decentralized applications (DApps).

The Rise of Layer 2 Blockchains

Ethereum’s transaction fees have been a major concern for users, with costs sometimes exceeding $100 per transaction during periods of high demand. To address this issue, developers have turned to layer 2 blockchains, which batch transactions before appending them to the Ethereum network. These layer 2 blockchains have gained significant traction, with over 40 currently in existence and another 35 in development. In fact, existing layer 2 blockchains have processed almost twice as many transactions as Ethereum itself over the past year.

The Challenges of Liquidity Fragmentation

While layer 2 blockchains have provided cost savings and scalability, they have also resulted in liquidity fragmentation. Each layer 2 blockchain operates as its own island, with assets and liquidity confined within its ecosystem. This fragmentation makes it challenging for users to access a larger pool of assets and execute large trades without impacting asset prices. PancakeSwap, a popular decentralized exchange, is an example of a protocol that exists on multiple layer 2 blockchains, but the assets on each version of PancakeSwap are isolated.

ZkLink Nova: Unifying Liquidity Across Layer 2s

ZkLink Nova, a new layer 3 blockchain, aims to address the liquidity fragmentation issue by aggregating liquidity across five layer 2 blockchains: zkSync, Linea, Arbitrum, Manta, and Mantle. By deploying applications on these blockchains, assets can be effectively shared, creating a larger pool of assets and deeper liquidity. This increased liquidity will make it easier for users to execute large trades without significantly impacting asset prices. ZkLink Nova settles on Linea, an L2 blockchain that utilizes zero-knowledge technology, offering additional savings on settlement costs.

The Benefits of zkLink Nova

Unlike existing layer 3 blockchains that are application-specific, zkLink Nova is a general-purpose blockchain. This means that it provides real interoperability and simplifies the decentralized finance (DeFi) experience by presenting a unified ecosystem for users and DApps. Users do not need to bridge assets across chains as the same ERC-20 token on zkSync and Linea, for example, is represented as a single token on zkLink Nova. This seamless blockchain experience enhances capital efficiency and promotes a more user-friendly DeFi environment.

The Future of zkLink Nova

ZkLink Nova’s roadmap includes plans to add more layer 2 blockchains in the future, expanding its reach and further unifying liquidity across various ecosystems. Additionally, zkLink Nova intends to launch its governance token, ZKL, which will incentivize a decentralized sequencer responsible for ordering transactions on layer 2 and layer 3 blockchains. This token issuance aims to enhance the decentralization and efficiency of the zkLink ecosystem.


ZkLink Nova’s launch as a layer 3 blockchain marks a significant step towards unifying liquidity across layer 2 blockchains. By aggregating liquidity and creating a unified ecosystem, zkLink Nova addresses the liquidity fragmentation issue that has hindered the scalability and accessibility of assets within the Ethereum ecosystem. As the demand for faster and cheaper transactions continues to grow, the emergence of layer 3 blockchains like zkLink Nova offers a promising solution for enhancing liquidity and improving the overall user experience in the DeFi space.
