The blockchain ecosystem continues to evolve at a rapid pace, driven by innovation in scalability, security, and user experience. As decentralized applications (dApps) proliferate across multiple chains, one of the most pressing challenges has become liquidity fragmentation — the dispersion of capital across isolated networks that hinders efficiency and limits growth. To address this, we’re proud to announce our strategic investment in zkLink through OKX Ventures, a move aimed at supporting the next generation of ZK-powered infrastructure designed to unify liquidity across Ethereum and its Layer 2 rollups.

Bridging the Gap with Zero-Knowledge Technology
At the heart of zkLink’s vision is the use of zero-knowledge proofs (ZK-proofs) — advanced cryptographic tools that enable secure, private, and scalable blockchain transactions. These proofs allow zkLink to aggregate assets from various Ethereum Layer 2 solutions into a single, high-performance Layer 3 network: zkLink Nova.
Nova functions as an aggregated zkEVM Layer 3, built on top of existing ZK and Optimistic Rollups. By doing so, it inherits the security of Ethereum while dramatically improving transaction speed and reducing costs. More importantly, it enables seamless interoperability between chains — a critical step toward eliminating siloed ecosystems and unlocking true cross-chain capital efficiency.
This approach directly tackles the problem of trapped liquidity, where users must lock up funds on individual rollups like Arbitrum, Optimism, zkSync, or Base without easy access to assets on other chains. With zkLink Nova, users can interact with a unified pool of capital across nine integrated ecosystems, including:
- Ethereum
- Arbitrum
- Optimism
- Base
- zkSync
- Linea
- Scroll
- Manta Pacific
- Mantle
Such broad integration ensures developers and traders can access deeper liquidity pools, reduce slippage, and execute more efficient trades — all within a single, cohesive environment.
Rapid Adoption and Real-World Impact
Since launching its mainnet in mid-March, zkLink Nova has achieved remarkable traction. Within just two months, the network secured over $1.05 billion in total value locked (TVL) — a strong indicator of market confidence and utility.
Equally impressive is the user growth: over 1 million unique wallet addresses have interacted with the network, executing more than 17 million transactions. This level of adoption underscores the demand for scalable, interoperable solutions in today’s multi-chain landscape.
What sets zkLink apart isn’t just technical innovation — it’s real-world usability. The platform offers an open, permissionless environment where dApps can deploy and leverage aggregated liquidity without complex cross-chain bridging logic. For end users, this translates into faster transactions, lower fees, and a smoother experience when moving between ecosystems.

Why This Matters for the Future of DeFi
Decentralized Finance (DeFi) has come a long way since its inception, but scalability and fragmentation remain persistent barriers to mass adoption. Most current solutions require users to manually bridge assets, manage multiple wallets, and accept varying degrees of trust and latency.
zkLink Nova reimagines this model by creating a centralized liquidity layer powered by decentralized infrastructure. Instead of forcing users to choose between security, speed, or accessibility, zkLink delivers all three through ZK-aggregation.
Core keywords naturally integrated throughout this discussion include:
- zkLink Nova
- aggregated rollups
- liquidity fragmentation
- zero-knowledge proofs
- Layer 3 network
- Ethereum Layer 2
- cross-chain interoperability
- DeFi scalability
These concepts are not just theoretical — they represent tangible advancements that are already reshaping how value moves across blockchains.
Frequently Asked Questions (FAQ)
Q: What is zkLink Nova?
A: zkLink Nova is an aggregated Layer 3 zkEVM network built on Ethereum’s Layer 2 rollups. It combines liquidity from multiple chains into a single platform using zero-knowledge technology, enabling faster, cheaper, and more efficient transactions.
Q: How does zkLink solve liquidity fragmentation?
A: By aggregating assets across nine major ecosystems — including Arbitrum, Optimism, and zkSync — zkLink Nova eliminates the need for repeated bridging and allows users to access unified liquidity pools on one network.
Q: Is zkLink Nova secure?
A: Yes. Nova inherits the security of Ethereum and leverages ZK-proofs to ensure trustless validation of transactions across integrated rollups, maintaining decentralization while enhancing scalability.
Q: What role does OKX Ventures play in this investment?
A: OKX Ventures supports early-stage blockchain projects with high growth potential. Our investment in zkLink reflects confidence in its ability to drive meaningful innovation in DeFi infrastructure and cross-chain interoperability.
Q: Can developers build on zkLink Nova?
A: Absolutely. zkLink Nova provides an open platform for dApp developers to deploy applications that benefit from aggregated liquidity, reduced latency, and native cross-chain functionality.
Q: Why focus on Layer 3 instead of improving Layer 2?
A: While Layer 2 solutions improve scalability, they often operate in isolation. Layer 3 networks like zkLink Nova sit atop multiple L2s, enabling aggregation, specialization, and enhanced composability — solving problems that L2s alone cannot address.

A Strategic Step Toward Unified Blockchain Ecosystems
Our investment in zkLink is more than financial support — it’s a commitment to advancing an open, interconnected blockchain future. As the number of rollups grows, so does the urgency for solutions that bring them together rather than push them further apart.
zkLink’s success in attracting over a million users and more than $1 billion in TVL in such a short time validates the market need for unified liquidity layers. Its use of zero-knowledge proofs ensures that this unification happens securely and efficiently — without sacrificing decentralization.
For developers, traders, and everyday users alike, zkLink Nova represents a significant leap forward in making multi-chain interactions seamless. It reduces friction, lowers costs, and opens new possibilities for innovation in DeFi, NFTs, gaming, and beyond.
As part of OKX’s broader mission to accelerate crypto adoption globally, we believe infrastructure projects like zkLink are essential building blocks for the next phase of web3 evolution.
In summary, zkLink isn’t just another rollup — it’s a foundational layer designed to connect them all. And with strong early performance metrics and growing ecosystem support, it’s well-positioned to become a cornerstone of the future decentralized internet.
