OKX has officially launched the public mainnet of X Layer, its Ethereum-based Layer 2 network. This launch represents a major step in addressing Ethereum's scalability challenges, offering users faster transactions and reduced fees.
Built using Polygon’s Chain Development Kit (CDK), X Layer incorporates zero-knowledge (ZK) proof technology to enhance security and efficiency. By processing transactions off-chain before finalizing them on Ethereum, it significantly improves network performance without compromising decentralization.
Furthermore, X Layer will interconnect with other chains developed with Polygon CDK through the AggLayer protocol. This enables seamless transfer of liquidity and assets across participating networks, boosting overall utility and user adoption.
Understanding the Need for Layer 2 Solutions
Ethereum remains the most widely used blockchain for decentralized applications (dApps), smart contracts, and token ecosystems. However, as activity increases, the network often becomes congested, leading to slow confirmation times and high gas fees. This has prompted the development of Layer 2 scaling solutions that operate on top of Ethereum, improving throughput while inheriting the security of the mainnet.
X Layer is OKX’s contribution to this growing ecosystem of scaling technologies. By leveraging advanced cryptographic techniques and interoperable infrastructure, it aims to provide a smoother and more affordable experience for developers and end-users.
How X Layer Works
X Layer uses zero-knowledge rollups to bundle multiple transactions into a single proof, which is then submitted to Ethereum. This reduces the data load on the mainnet, cuts costs, and accelerates processing times. The integration with Polygon’s CDK ensures compatibility with a wide set of tools and existing Ethereum standards.
Another core feature is its connection to AggLayer, a unification layer that allows different blockchains to share liquidity and state information. This means users can move assets between X Layer and other supported chains without traditional bridging complexities.

The Expanding X Layer Ecosystem
Since its testnet launch in November 2023, X Layer has attracted significant developer interest. More than 50 dApps deployed on the network within the first week, indicating strong community support.
Prominent DeFi protocols and infrastructure projects such as Curve, QuickSwap, The Graph, and LayerZero are already being integrated into X Layer. This growing ecosystem enhances the network’s usefulness, offering services in decentralized trading, lending, data indexing, and cross-chain communication.
Haider Rafique, Chief Marketing Officer at OKX, emphasized that X Layer is designed for builders creating applications that can onboard millions of users into the Web3 space. He described Layer 2 networks as the highways of the decentralized internet, enabling efficient and scalable movement of value and data.
Benefits of Using X Layer
- Lower transaction fees: By aggregating transactions, X Layer minimizes gas costs for users.
- Faster processing: Transactions are confirmed within seconds rather than minutes.
- Ethereum security: All operations are ultimately secured by Ethereum’s consensus mechanism.
- Interoperability: Cross-chain functionality via AggLayer simplifies asset transfers.
- Developer-friendly: Full compatibility with Ethereum Virtual Machine (EVM) allows easy migration of dApps.
Frequently Asked Questions
What is a Layer 2 blockchain?
A Layer 2 is a secondary protocol built on top of a Layer 1 blockchain like Ethereum. It handles transactions off-chain to reduce load on the main network, thereby increasing speed and lowering costs while maintaining security.
How is X Layer different from other L2 solutions?
X Layer uses ZK-rollups for scalability and is interconnected with other chains via Polygon’s AggLayer. This offers users not just scalability but also seamless cross-chain liquidity and composability.
Can I use my existing Ethereum wallet on X Layer?
Yes, X Layer is EVM-compatible, meaning you can use popular Ethereum wallets like MetaMask to interact with dApps on the network. You may need to add the X Layer network manually.
What types of applications are available on X Layer?
The network supports a wide range of dApps including decentralized exchanges, lending platforms, NFT marketplaces, gaming applications, and infrastructure tools.
Is X Layer secure?
Yes, X Layer uses zero-knowledge proofs for transaction integrity and relies on Ethereum for final settlement, making it highly secure.
How can developers build on X Layer?
Developers can deploy smart contracts using familiar tools like Hardhat or Remix. Documentation and support are available through OKX and Polygon’s developer portals.
Conclusion
The launch of X Layer marks an important milestone in OKX’s effort to improve blockchain scalability and usability. With its strong technical foundation, interoperability features, and expanding dApp ecosystem, X Layer is well-positioned to become a significant player in the Layer 2 landscape.
For developers and users alike, X Layer offers a practical pathway to engaging with Ethereum-based applications in a more efficient and cost-effective manner.
