The Web3 landscape has taken a significant leap forward with the official launch of X Layer, a next-generation Ethereum Layer 2 network developed by OKX, one of the world’s leading cryptocurrency exchanges and Web3 technology innovators. Unveiled on April 16, the public mainnet marks a pivotal moment in blockchain scalability, aiming to onboard millions of users into decentralized applications (dApps) with faster, cheaper, and more secure transactions.
Built on ZK technology and powered by Polygon CDK, X Layer is engineered for high performance and seamless interoperability. By integrating AggLayer, it enables shared state and unified liquidity across multiple blockchains—addressing one of the most pressing challenges in the current multi-chain ecosystem: fragmentation.
A High-Performance Infrastructure for Web3
At its core, X Layer is designed to serve as foundational infrastructure for the future of decentralized applications. By leveraging zero-knowledge rollups (ZK-Rollups), the network ensures transaction security while drastically reducing gas fees and confirmation times. This makes it ideal for both retail users and enterprise-grade dApps requiring scalable and cost-efficient solutions.
Importantly, X Layer is EVM-compatible, allowing developers to deploy Ethereum-based dApps with minimal modifications. This compatibility lowers the entry barrier for projects already operating within the Ethereum ecosystem, enabling rapid migration and deployment.

Strategic Vision from OKX Leadership
Haider Rafique, Chief Marketing Officer at OKX, emphasized the broader vision behind X Layer:
“X Layer is built for forward-thinking developers who are creating applications to bring millions onto the blockchain. Think of X Layer and other Layer 2s as the highways of the Web3 world—dApps are the markets, and self-custody wallets are the vehicles that get users there. Our goal is to build an ecosystem that’s as seamless and interoperable as possible.”
With over 50 million users across its exchange and wallet platforms, OKX provides X Layer with immediate access to a massive user base—ensuring strong initial liquidity and real-world usage from day one.
Rapid Developer Adoption and Ecosystem Growth
Even before the public mainnet launch, X Layer saw explosive interest from the developer community. Since the testnet rollout in November 2023, more than 50 Web3 dApps have deployed or announced plans to integrate, including major names like:
- The Graph
- Curve
- LayerZero
- QuickSwap
- Galxe
- Timeswap
These integrations highlight growing confidence in X Layer’s technical foundation and long-term viability. Users can now transfer assets via the X Layer network, deposit and withdraw crypto through OKX, and interact with over 170 dApps for swapping, staking, yield farming, and more—all powered by smart contracts.
As the mainnet opens to the public, experts anticipate exponential growth in both application development and user engagement.
OKB as the Native Gas Token
One of the key economic design choices for X Layer is the use of OKB, OKX’s native utility token, as the primary gas fee currency. This integration strengthens OKB’s utility beyond exchange-based functions, anchoring it firmly within a live blockchain ecosystem.
Holders benefit from reduced transaction costs, governance potential, and increased demand as network activity grows—making OKB a central component of X Layer’s long-term sustainability.
Powered by Polygon CDK and AggLayer
X Layer’s technical backbone lies in Polygon CDK (Chain Development Kit), a cutting-edge SDK tailored for building ZK-powered Layer 2s on Ethereum. The framework simplifies development workflows, allowing teams to spin up secure, customizable rollups with ease.
Moreover, OKX developers are actively contributing to the evolution of Polygon CDK, ensuring continuous innovation in core tech stacks such as proof systems, data availability layers, and cross-chain messaging protocols.
Crucially, X Layer connects to other chains built on Polygon CDK through AggLayer, Polygon’s aggregation layer designed to unify liquidity and state across ecosystems. This eliminates silos and enables seamless asset movement—addressing liquidity fragmentation that plagues many current multi-chain environments.
Marc Boiron, CEO of Polygon Labs, commented:
“X Layer represents a milestone in building a truly unified Web3. Its integration with AggLayer solves cross-chain liquidity fragmentation, enabling shared growth. With OKX’s 50 million+ users now able to access X Layer and connected chains effortlessly, we’re unlocking new possibilities for developers and users alike.”
