The next era of the internet is being built—decentralized, open, and user-owned. At the heart of this transformation is X Layer, a cutting-edge Layer2 network co-developed by OKX and Polygon Labs. Built with Polygon’s Chain Development Kit (CDK) and powered by ZK (Zero-Knowledge) proof technology, X Layer is engineered to scale Ethereum while delivering low-cost, high-speed, and fully compatible infrastructure for developers, creators, and Web3 enthusiasts.
With the launch of its testnet, X Layer is now live and integrated with OKX, Polygon, and Ethereum, opening the door for builders worldwide to start developing on a scalable, secure, and seamless ecosystem. This is more than just another blockchain—it’s a strategic step toward mass Web3 adoption.

Why Build X Layer?
Web3 promises a future where users control their data, identities, and digital assets. But for this vision to go mainstream, it must overcome two major hurdles: high transaction costs and limited interoperability.
Ethereum, despite being the foundation of most decentralized applications (dApps), often suffers from congestion and expensive gas fees. Other networks struggle with fragmented ecosystems and poor developer tools. This friction discourages innovation and slows down user adoption.
X Layer was created to solve these challenges—not by competing with Ethereum, but by extending its capabilities. Instead of reinventing the wheel, X Layer enhances what already works:
- Scale Ethereum, don’t replace it: By leveraging ZK-rollup technology, X Layer inherits Ethereum’s security while processing transactions off-chain and batching them for on-chain verification.
- Support billions of users: The infrastructure is designed for massive scalability, ensuring smooth performance even as demand grows.
- Enable true interoperability: Seamless connectivity across OKX, Polygon, and Ethereum ecosystems allows assets and data to flow freely.
This mission isn’t just technical—it’s philosophical. X Layer believes in an open, inclusive Web3 where developers can innovate without limits and users can transact without friction.
What Makes X Layer Stand Out?
X Layer was built for developers, by builders who understand the real-world needs of the Web3 community. Here’s how it delivers a superior experience:
🔗 Unified Ecosystem Powerhouse
By combining the strengths of OKX’s vast user base (over 50 million global users) and Polygon Labs’ proven ZK technology, X Layer offers a powerful foundation for next-generation dApps. Developers gain access to advanced tooling, robust infrastructure, and a ready-made audience—all within an ecosystem designed for growth.
💡 Native Gas with OKB
One of X Layer’s standout features is its support for OKB as a native gas token. This means users can pay transaction fees directly with OKB—the platform token of OKX—enabling seamless value transfer between OKX services and the X Layer network.
This integration reduces friction for existing OKX users and creates a unified economic model that rewards participation across both platforms.

✅ Full EVM Compatibility
X Layer is fully compatible with the Ethereum Virtual Machine (EVM). That means:
- Existing smart contracts require no rewrites.
- Popular developer tools like Hardhat, Truffle, and Remix work out of the box.
- Wallets such as MetaMask function seamlessly.
- dApps can migrate from Ethereum or other EVM chains with near-zero cost and effort.
This compatibility dramatically lowers the barrier to entry for developers already familiar with Ethereum’s ecosystem.
⚡ Low-Cost & High-Performance Transactions
Powered by optimized zkSNARKs (a type of zero-knowledge proof), X Layer achieves high throughput with minimal fees. Unlike traditional blockchains that slow down under load, ZK-rollups bundle hundreds of transactions into a single cryptographic proof, which is then verified on Ethereum—resulting in faster confirmations and lower costs.
Additionally, X Layer runs on state-of-the-art hardware clusters using one of the world’s fastest ZK proof systems, ensuring rapid finality and responsiveness even during peak usage.
Core Advantages at a Glance
- Scalability: Designed to handle millions of transactions per second through ZK-rollup efficiency.
- Security: Inherits Ethereum’s battle-tested consensus and cryptographic integrity.
- Developer-Friendly: Full EVM compatibility, extensive documentation, and SDKs.
- Interoperability: Native bridges to Ethereum, Polygon, and OKX ecosystem components.
- Sustainability: Energy-efficient ZK technology aligns with long-term environmental goals.
These features make X Layer an ideal platform for DeFi protocols, NFT marketplaces, gaming dApps, social networks, and more.

Frequently Asked Questions (FAQ)
Q: Is X Layer a new blockchain or a sidechain?
A: X Layer is a Layer2 rollup built using Polygon CDK and ZK technology. It’s not a sidechain—it securely scales Ethereum by posting transaction data on-chain while processing transactions off-chain.
Q: Can I use MetaMask with X Layer?
A: Yes! Since X Layer is EVM-compatible, wallets like MetaMask work seamlessly. You just need to add the network configuration manually or through wallet integration.
Q: Do I need special tools to deploy smart contracts on X Layer?
A: No. Standard Ethereum development tools such as Hardhat, Remix, and Solidity are fully supported. Migration from Ethereum requires minimal changes.
Q: How does using OKB as gas benefit me?
