The future of Web3 is accelerating with the launch of X Layer, a high-performance, secure, and developer-friendly Ethereum-based Zero-Knowledge (zk) Layer-2 (L2) network. Developed in strategic collaboration between OKX, a global leader in cryptocurrency and Web3 innovation, and Polygon Labs, a pioneer in Ethereum scaling solutions, X Layer marks a significant leap toward mass adoption of decentralized technologies.
Built using the Polygon Chain Development Kit (CDK), X Layer is designed to connect OKX’s 50 million+ global users with the vast developer ecosystems of Polygon and Ethereum—two of the most active and innovative communities in the blockchain space. This integration not only enhances accessibility but also fosters seamless interoperability across major blockchain networks.
A New Native Network for Web3 Innovation
X Layer is set to become OKX’s new native blockchain network, providing a robust foundation for developers, creators, and Web3 enthusiasts. The network’s native utility token will be OKB, OKX’s platform token, which will be used to pay for gas fees—streamlining user experience and reinforcing token utility within a high-throughput environment.
As a zkEVM-compatible chain, X Layer leverages Zero-Knowledge proofs to deliver enhanced security, scalability, and cost-efficiency. Transactions are batched and verified off-chain before being posted to Ethereum, drastically reducing congestion and fees while maintaining Ethereum-level security.
Developers can seamlessly deploy EVM-compatible dApps, smart contracts, wallets, and tools—without needing to rewrite code. This compatibility lowers entry barriers and accelerates time-to-market for new decentralized applications across DeFi, NFTs, GameFi, enterprise solutions, and more.

Driving Ethereum Scaling Through Strategic Collaboration
Beyond launching a new L2, OKX is stepping into a deeper technical role by becoming a core contributor to the Polygon CDK. This means OKX will dedicate substantial engineering resources to advancing the underlying technology that powers Ethereum scaling solutions.
The Polygon CDK, launched in late 2023, enables organizations to spin up customizable zk-powered Layer-2 chains on Ethereum with unified liquidity and infinite scalability. By contributing to this open-source framework, OKX is helping shape the future of interoperable, high-performance blockchains.
This collaboration opens the door for cross-chain synergy, where multiple CDK-based L2s—including those from Astar (Polkadot), Canto (Cosmos), Gnosis Pay, and others—can interoperate within a unified ecosystem of ZK-powered networks.
“X Layer will be a key pillar of our efforts to educate and bring our users onchain and into the world of Web3,” said Jason Lau, Chief Innovation Officer at OKX. “This scalable and accessible network is perfect for developers who can build on X Layer to deliver user-friendly, world-class consumer Web3 applications—all while maintaining interoperability with other networks.”
Why X Layer Stands Out in the L2 Landscape
While numerous L2 solutions exist, X Layer differentiates itself through three core advantages:
- Developer-Centric Design: From day one, X Layer prioritizes ease of use, comprehensive tooling, and robust documentation—making it ideal for both novice and enterprise-grade developers.
- Massive User Base Access: With direct access to over 50 million OKX users, builders on X Layer gain immediate exposure to one of the largest crypto-native audiences globally.
- Security & Scalability via ZK Technology: Unlike optimistic rollups, zk-rollups offer cryptographic proof of validity, eliminating long withdrawal periods and trust assumptions.
These features position X Layer as a go-to platform for teams aiming to scale securely without sacrificing decentralization or user experience.

Bridging Communities for Mass Adoption
One of X Layer’s most transformative aspects is its ability to bridge communities. By connecting OKX’s vast user base with Polygon’s extensive developer network and Ethereum’s unmatched security, the project creates a powerful flywheel for innovation.
Sandeep Nailwal, co-founder of Polygon, emphasized this synergy:
“The X Layer network offers developers an affordable and user-friendly platform to create decentralized apps, seamlessly bridging the vast OKX community with the Polygon and wider Ethereum ecosystems. The utilization of Polygon CDK technology represents a significant leap forward… We’re excited to collaborate with OKX's team to advance this technology and drive the success of the X Layer network.”
This alignment isn’t just technical—it’s cultural. With shared values around decentralization, transparency, and sustainability (Polygon Labs is carbon neutral), both organizations are committed to building a responsible Web3 future.
Upcoming Developments and Developer Engagement
In the coming weeks, OKX and Polygon Labs will unveil more technical details about X Layer’s architecture, governance model, and tokenomics. Additionally, a series of developer events, hackathons, and grant programs will be announced to fuel early ecosystem growth.
Builders interested in participating will have access to:
- SDKs and APIs for easy integration
- Testnet environments with faucet support
- Developer grants and incubation opportunities
- Direct technical support from OKX and Polygon engineering teams
Such initiatives are critical for nurturing talent and encouraging experimentation—key ingredients for long-term ecosystem vitality.
Frequently Asked Questions (FAQ)
