Introducing X Layer: A Next-Generation ZK-Powered EVM Chain
Calling all Web3 builders, developers, and innovators — the future of decentralized application development is here. Today marks a pivotal moment in the evolution of blockchain infrastructure with the launch of X Layer, a cutting-edge, Ethereum-compatible Layer 2 (L2) network built using the Polygon Chain Development Kit (CDK) in collaboration with Polygon Labs.
X Layer is engineered to deliver high scalability, robust security, and ultra-low transaction costs through zero-knowledge (ZK) proof technology. As a native L2 solution, it enables seamless interoperability across major ecosystems while supporting gas payments in OKB, the native token of the OKX platform.
With the testnet now live, X Layer opens the door for developers worldwide to begin building on a unified, future-ready blockchain infrastructure. This network is designed not to compete with Ethereum, but to enhance and scale its thriving ecosystem — making it easier than ever to create consumer-grade Web3 applications that are fast, affordable, and accessible to billions.

Why X Layer Was Built: Scaling Web3 for Mass Adoption
Web3 represents a fundamental shift in how we interact with digital systems — placing control back into the hands of users through decentralization, transparency, and permissionless innovation. But for this vision to reach mainstream audiences, significant challenges remain: high gas fees, network congestion, and fragmented liquidity.
To accelerate global adoption, we believe the most effective strategy is not to create isolated chains, but to scale Ethereum — the largest and most secure smart contract ecosystem. That’s where X Layer comes in.
By leveraging ZK-rollup technology and the Polygon CDK, X Layer offers a scalable infrastructure capable of handling billions of users without compromising security or decentralization. It’s built for the next wave of Web3 growth: one that bridges existing communities, unifies liquidity, and removes technical and economic barriers for developers and end users alike.
This isn’t just about performance — it’s about creating an inclusive digital economy where innovation can flourish at scale.
What Sets X Layer Apart? Key Features and Advantages
Seamless Ethereum Compatibility
One of X Layer’s core strengths is full EVM (Ethereum Virtual Machine) compatibility. This means developers can deploy existing smart contracts, use familiar tools like Hardhat and Remix, and connect with popular wallets such as MetaMask — all without any code modifications.
For projects already running on Ethereum, migration to X Layer is fast, free, and frictionless. This compatibility dramatically lowers entry barriers and allows teams to focus on building rather than re-engineering.
Unified Ecosystem Access Through Strategic Collaboration
X Layer is the result of a powerful collaboration between OKX and Polygon Labs. By contributing to the ongoing development of the Polygon Chain Development Kit, both teams are committed to advancing modular blockchain architecture.
This partnership brings together two of the most active Web3 ecosystems, enabling shared innovation, cross-community developer engagement, and accelerated project deployment. The synergy between these networks creates a stronger foundation for long-term growth.
Low-Cost Transactions via Advanced zkSNARKs
X Layer utilizes optimized zkSNARK technology to compress transaction data before batching it to Ethereum. This results in significantly reduced on-chain footprint — translating directly into lower fees for users and developers.
These savings make microtransactions viable and enable new use cases in gaming, social apps, and DeFi that were previously cost-prohibitive on other chains.
High Throughput and Fast Finality
Speed matters. X Layer achieves rapid transaction confirmation times thanks to one of the fastest ZK proof generation systems in the industry, powered by advanced hardware acceleration. Users experience near-instant finality without sacrificing security — a critical advantage for real-time applications like decentralized exchanges and NFT marketplaces.
Native Integration with a Global Crypto Platform
As part of the OKX ecosystem — serving over 50 million users worldwide — X Layer benefits from immediate access to a vast user base, deep liquidity, and integrated financial tools. Developers gain exposure to a ready-made audience, while users enjoy seamless asset transfers between OKX products and X Layer using OKB as gas.
This integration provides a unique launchpad for new projects aiming for rapid traction and scalability.

Frequently Asked Questions (FAQ)
Q: Is X Layer fully compatible with Ethereum?
A: Yes. X Layer is fully EVM-compatible, meaning all existing Ethereum dApps, wallets, and developer tools work seamlessly without requiring code changes.
Q: What consensus mechanism does X Layer use?
A: X Layer is a ZK-rollup that leverages zero-knowledge proofs to batch transactions off-chain and publish cryptographic proofs to Ethereum for final settlement.
Q: Can I use OKB to pay for gas on X Layer?
A: Absolutely. OKB serves as the native gas token on X Layer, enabling users to pay transaction fees directly with their holdings.
Q: Is the X Layer testnet open to everyone?
A: Yes. The testnet is publicly accessible, allowing developers and enthusiasts to experiment, deploy contracts, and provide feedback ahead of mainnet launch.
Q: How does X Layer ensure security?
A: Security is anchored by Ethereum’s base layer. All transactions are verified via ZK proofs and posted on Ethereum, inheriting its high level of decentralization and resistance to attacks.
Q: How does X Layer differ from other L2 solutions?
A: Unlike many L2s operating in isolation, X Layer emphasizes interoperability, ecosystem alignment with Polygon CDK, and direct integration with a major crypto platform — offering both technical and network advantages.
What’s Next for X Layer?
The journey has just begun. With the testnet now active, the focus shifts to onboarding developers, launching incentive programs, and expanding ecosystem partnerships. We’re working closely with leading projects across DeFi, NFTs, gaming, and infrastructure to bring innovative applications to life on X Layer.
Our long-term vision is clear: empower builders to bring Web3 to the next billion users by solving scalability without compromising security or decentralization. To achieve this, collaboration is key — which is why we invite every developer, creator, and innovator to join us.
The tools are ready. The infrastructure is live. The opportunity is now.
