The X Layer mainnet is officially live — a powerful, EVM-compatible, zero-knowledge (ZK) Layer 2 (L2) blockchain now hosting over 200 decentralized applications (dApps). Built to scale Ethereum and empower the next generation of Web3 innovation, X Layer delivers faster transactions, lower fees, and seamless integration with leading Web3 tools.
Backed by OKX, X Layer combines cutting-edge ZK technology with deep ecosystem support to create a robust foundation for developers and users alike. Whether you're building dApps or interacting with DeFi, NFTs, gaming, or SocialFi platforms, X Layer offers a scalable and user-friendly environment designed for mass adoption.
👉 Discover how top Web3 developers are leveraging ZK-powered scaling today.
Seamless Integration with OKX Ecosystem
X Layer is natively integrated with OKX Exchange (CEX) and OKX Web3 Wallet, enabling smooth asset transfers between centralized and decentralized environments. Users can instantly bridge funds from OKX Exchange to X Layer or connect their OKX Web3 Wallet to access dApps across the network.
This tight integration reduces friction for millions of users entering Web3, offering a unified experience that bridges traditional crypto onboarding with advanced decentralized functionality.
The name X Layer reflects both openness and interoperability — “X” symbolizing connectivity, while “Layer” represents the diverse protocols working together to enhance blockchain scalability. Rather than focusing on a single use case, X Layer is built as a versatile infrastructure layer, enabling developers to build new "layers" for countless on-chain applications.
Key Milestones Since Testnet Launch
Since its testnet phase, X Layer has attracted thousands of active developers and onboarded more than 200 dApps, showcasing strong community momentum and technical readiness. The network leverages ZK-EVM technology to deliver high throughput and low-cost transactions while maintaining full compatibility with Ethereum’s development tools and smart contracts.
Current dApp distribution across the ecosystem includes:
- ~40 DeFi protocols
- 20 infrastructure projects
- 12 bridge solutions
- 5 growth tools
- 16 wallets
- 10 NFT and gaming platforms
- 10 SocialFi applications
- Plus various developer tools
Notable Web3 projects already live on X Layer include:
- DeFi: Curve, Renzo, QuickSwap
- Infrastructure: LayerZero, Wormhole, Chainlink, EigenLayer (DA layer)
With the mainnet now public, the focus shifts toward accelerating developer adoption and expanding user access. The goal is clear: deliver a smooth, efficient, and scalable L2 experience that fuels innovation in the ZK and broader Web3 space.
Long-Term Vision: Building the Future of Web3
At its core, OKX is a technology company committed to advancing blockchain’s transformative potential. Since launching in 2014, we’ve built one of the world’s largest digital asset ecosystems — from self-custody wallets to cross-chain bridges, token creation tools, and now our own ZK-EVM L2.
Our vision for X Layer centers on three foundational pillars:
1. Simplified dApp User Experience
Making decentralized applications accessible to everyone means removing complexity. X Layer achieves this through:
- Cross-chain bridges that enhance interoperability and accessibility
- Intuitive setup flows and interaction design
- Native integration with OKX Web3 Wallet, providing a seamless, user-first interface
- Advanced wallet features like account abstraction, enabling smart contract wallets with social recovery and gasless transactions
2. Empowering Developers & Creators
To foster innovation, we’re equipping builders with the tools they need:
- A comprehensive developer toolkit developed in collaboration with Polygon Labs
- Close partnerships to help teams bring their visions to life on X Layer
- Timely, well-documented resources guiding developers through deployment and optimization
- Direct access to a vast user base — millions of active OKX users ready to test and engage with new dApps

3. Faster, Lower-Cost On-Chain Experience
Scalability is at the heart of X Layer:
- Drastically reduced transaction fees make dApp usage affordable for all
- Optimized transaction batching and validation increase throughput (TPS)
- ZK-powered security ensures fast finality without sacrificing decentralization
Over recent years, OKX has introduced industry-first innovations — from our open-source, self-hosted wallet to built-in swap, bridge, and discovery tools across hundreds of networks. We launched support for Ordinals and推出了 multiple token creation protocols to welcome diverse use cases.
In late 2024, we announced our plan to build a custom L2 for Ethereum — a natural evolution in our mission to improve how people interact with on-chain applications.
Web3 Building Blocks: A New Transportation Metaphor
We envision the future of Web3 as an interconnected ecosystem of modular components — what we call next-gen Web3 building blocks. Think of it like modern transportation:
- Access & Storage (Your vehicle and storage space) → The Wallet: A self-custodied, open-source wallet with full interoperability
- Markets (Destinations and services) → dApps: Platforms where you can swap, bridge, create, trade, and explore
- Infrastructure (Highways) → The L2 Network: A secure, low-cost, ZK-EVM-powered highway connecting you directly to Ethereum-based dApps
This framework simplifies the complexity of Web3, making it easier for users to understand their journey and for developers to design intuitive experiences.
Accelerating Global Web3 Adoption
X Layer aims to drive global adoption of the Web3 economy by ensuring greater individual freedom and equal opportunity for millions worldwide. By combining performance, affordability, and ease of use, we’re laying the groundwork for mainstream blockchain usage.
We’re excited about what’s ahead — and we invite you to join us in shaping the future of decentralized technology.
