The Web3 ecosystem took a major leap forward on April 16 with the official launch of X Layer, a new Ethereum Layer 2 network introduced by OKX, one of the world’s leading cryptocurrency exchanges and Web3 technology innovators. Built on cutting-edge ZK technology and powered by Polygon CDK, X Layer is designed to make blockchain interactions faster, cheaper, and more accessible for millions of users worldwide.
Backed by seamless EVM compatibility, X Layer allows developers to deploy existing Ethereum-based dApps with minimal effort. Its integration with AggLayer further enhances cross-chain interoperability, enabling shared state and fluid movement of assets across multiple chains. This strategic architecture positions X Layer as a foundational layer for the next phase of decentralized application growth.

A New Era of Scalability and Interoperability
Scalability has long been a bottleneck for Ethereum, with high gas fees and slow transaction speeds limiting mainstream adoption. X Layer addresses these challenges head-on by leveraging zero-knowledge (ZK) rollup technology, which batches transactions off-chain before settling them securely on Ethereum. This approach drastically reduces costs and latency while maintaining the security guarantees of the Ethereum mainnet.
What sets X Layer apart is its focus on interoperability. By integrating with AggLayer, it connects not just to Ethereum but also to other Polygon CDK-powered chains, creating a unified liquidity layer. This means users can move assets and data across ecosystems without friction—eliminating the silos that have historically plagued multi-chain environments.
For developers, this translates into a powerful environment where dApps can interact across chains natively. For end users, it means a smoother experience: one wallet, one identity, and access to a growing universe of decentralized services.
Rapid Adoption and Growing Ecosystem
Even before its public mainnet launch, X Layer demonstrated strong momentum. Since the testnet debut in November 2023, over 50 Web3 applications have deployed or announced plans to launch on the network. Notable projects include:
- The Graph – For decentralized data indexing
- Curve – Leading decentralized exchange for stablecoins
- LayerZero – Cross-chain interoperability protocol
- QuickSwap – AMM DEX optimized for speed
- Galxe – Web3 credential and engagement platform
- Timeswap – Decentralized lending and borrowing protocol
Today, users can already transfer assets via the X Layer network, manage holdings through OKX Wallet, and interact with over 170 dApps for swapping, staking, and more. With the public mainnet now live, the pace of adoption is expected to accelerate exponentially.
Powered by OKX’s Global Reach
OKX brings unparalleled scale to this initiative. With over 50 million users globally and daily trading volumes ranking among the highest in the industry, OKX provides X Layer with immediate liquidity and a vast user base ready to engage with Web3 applications.
Moreover, OKB, OKX’s native utility token, serves as the gas token for X Layer. This creates real-world utility for OKB within a high-performance L2 environment, reinforcing its role beyond exchange-based functions.
OKX Wallet further strengthens the ecosystem. Supporting 90+ public blockchains, it features integrated DEX and NFT aggregators, making it one of the most advanced gateways into Web3. Users can seamlessly connect to X Layer and begin exploring DeFi, GameFi, NFTs, and metaverse applications—all from a single interface.

Built on Polygon CDK: A Developer-First Foundation
X Layer is constructed using Polygon Chain Development Kit (CDK), a modular framework tailored for building ZK-powered Ethereum L2s. The CDK simplifies development by offering pre-audited components, customizable consensus mechanisms, and out-of-the-box connectivity to Ethereum.
Beyond infrastructure, OKX developers are actively contributing to the evolution of Polygon CDK itself—ensuring continuous innovation at the protocol level. This collaborative effort strengthens not only X Layer but the broader Polygon-powered ecosystem.
As Marc Boiron, CEO of Polygon Labs, stated:
“X Layer marks a milestone toward a truly unified Web3. Its integration with AggLayer solves the critical issue of liquidity fragmentation across chains. Now, OKX’s 50 million users can effortlessly access X Layer and other AggLayer-connected networks. The strong developer interest proves the network’s potential—we’re excited to keep building together.”
Unlocking Mass Adoption Through Accessibility
The vision behind X Layer extends beyond technical superiority—it's about democratizing access to decentralized technologies.
By reducing transaction costs and simplifying onboarding through familiar platforms like OKX and OKX Wallet, X Layer removes two of the biggest barriers to entry in Web3: complexity and cost. Whether you're a developer launching a new DeFi protocol or a user trying your first NFT mint, the experience is designed to be intuitive and efficient.
Furthermore, OKX’s partnerships with global brands like Manchester City FC, McLaren F1 Team, and the Tribeca Festival help bridge traditional audiences with blockchain experiences—driving awareness and engagement at scale.
These collaborations aren’t just marketing plays; they’re pathways for real-world utility. Fans can earn digital collectibles, participate in exclusive events, and explore token-gated communities—all powered by infrastructure like X Layer.
