OKX, a leading crypto exchange and Web3 technology company, has officially launched the public mainnet of its innovative Ethereum-based Layer-2 network, X Layer. This Zero Knowledge (ZK) powered scaling solution is designed to bring the platform’s 50 million users into the world of on-chain applications with greater speed, affordability, and security.
Built using the Polygon Chain Development Kit (CDK), X Layer enables shared liquidity and state across multiple blockchains via the AggLayer. The network is EVM-compatible, allowing Ethereum-based decentralized applications (dApps) to be deployed seamlessly with minimal development effort.
What Is X Layer?
X Layer is a ZK-powered Layer-2 blockchain built on Ethereum. It uses advanced zero-knowledge proof technology to bundle transactions off-chain before submitting verification proofs to the main Ethereum network. This approach significantly reduces transaction costs and increases throughput while maintaining a high level of security.
The network is designed for both developers and end-users, offering a scalable environment for dApps and a user-friendly experience for those transacting or interacting with smart contracts.
Key Features of X Layer
EVM Compatibility
X Layer is fully compatible with the Ethereum Virtual Machine (EVM). This means developers can port existing Ethereum dApps to X Layer with little to no code changes, accelerating deployment and reducing development overhead.
ZK Proof Technology
By leveraging zero-knowledge proofs, X Layer ensures that transactions are not only faster and cheaper but also highly secure and private. This technology allows the network to scale efficiently without compromising decentralization.
Seamless Interoperability
Through integration with Polygon’s AggLayer, X Layer enables cross-chain liquidity and communication. Users can transfer assets and interact with dApps across multiple connected chains without dealing with fragmented liquidity pools.
Supported dApps and Ecosystem Growth
Since its testnet launch in late 2023, X Layer has seen rapid adoption from major Web3 projects. Dozens of top-tier dApps from sectors including DeFi, NFTs, and infrastructure have already deployed on the network.
Notable integrations include:
- The Graph – for decentralized indexing and querying
- Curve – a leading decentralized exchange for stablecoin trading
- LayerZero – enabling omnichain interoperability
- QuickSwap – a popular DEX on Polygon
- Galxe – a Web3 credential data network
- Timeswap – a decentralized lending protocol
Over 170 dApps are already accessible on X Layer, with many more in the process of deployment. Users can perform a wide range of activities including swapping tokens, staking, and interacting with smart contracts.

Benefits for Users and Developers
For Users:
- Lower Fees: Significantly reduced gas costs compared to Ethereum mainnet.
- Faster Transactions: High throughput with near-instant confirmation times.
- Access to dApps: A rapidly growing ecosystem of decentralized applications.
- Easy On-Ramping: Users can deposit, withdraw, and transfer assets directly through the OKX exchange.
For Developers:
- Easy Migration: EVM compatibility simplifies porting existing dApps.
- Shared Liquidity: Access to aggregated liquidity across chains via AggLayer.
- Scalable Infrastructure: A high-performance environment for user-facing applications.
The Role of OKB Token
OKB, the native utility token of the OKX ecosystem, serves as the gas token on X Layer. Users need OKB to pay for transaction fees when interacting with dApps or transferring assets on the network. This integration reinforces the token’s utility and aligns with OKX’s vision of a unified Web3 experience.
Partnership with Polygon
X Layer is built using Polygon’s CDK, a modular open-source toolkit for launching ZK-powered L2 chains on Ethereum. This collaboration allows OKX to contribute to the core tech stack while benefiting from Polygon’s established scaling infrastructure.
The connection to AggLayer is particularly significant, as it enables X Layer to interoperate with other chains in the Polygon ecosystem, creating a unified network of users and liquidity.
