As Ethereum L2s multiply, new layer 3 blockchain aims to stitch them together. ZkLink Nova, which launched Monday, aggregates liquidity across five layer 2 blockchains: zkSync, Linea, Arbitrum, Manta, and Mantle.

DL News reports that zkLink Nova, a new so‑called Layer 3 blockchain built on Ethereum, has launched with the goal of aggregating liquidity from multiple Ethereum Layer 2 networks into a single environment. Nova is described by its team as an “aggregated Layer 3 zkEVM rollup” that connects several L2s and Ethereum mainnet, allowing assets and activity from these chains to be combined on one execution layer. According to project documentation and partners, zkLink Nova currently focuses on unifying liquidity from rollups such as zkSync, Linea, Arbitrum, Manta, and Mantle, enabling users and applications to interact with assets originating from these ecosystems through a single interface while settling security on Ethereum via zero‑knowledge proofs. Technically, zkLink Nova is built with zkSync’s ZK Stack and functions as an EVM‑compatible zkRollup (or zkEVM), using Ethereum as the base layer and relying on zero‑knowledge proofs to verify batched transactions. The network aims to address liquidity fragmentation across the fast‑growing landscape of Ethereum L2 rollups by aggregating “scattered assets” from different L2s and merging tokens of the same type (for example, ETH or USDC) into unified representations on Nova. This design is targeted at cross‑chain DEXs, perpetuals, and omni‑chain DeFi and NFT applications that require shared liquidity, offering low fees, fast finality, and Ethereum‑inherited security. By positioning itself as an “aggregated” Layer 3 on top of existing L2s, zkLink Nova reflects a broader trend in Ethereum scaling: as the number of rollups grows, new infrastructure layers are emerging to abstract away chain complexity and provide developers and users with a more unified multi‑chain experience.
