OKX Unveils X1: Revolutionizing Web3 with New ZK Layer 2 Network

·

The Next Evolution in Blockchain: Introducing X1

In a landmark moment for the Web3 ecosystem, OKX and Polygon Labs have jointly launched X1—a next-generation Zero Knowledge (ZK) Layer 2 network built on Ethereum. This powerful collaboration brings together one of the world’s leading crypto exchanges and a pioneering blockchain development team to create a scalable, secure, and developer-centric platform designed to accelerate the future of decentralized applications.

X1 is not just another Layer 2 solution—it represents a strategic leap forward in how blockchain networks can support mass adoption, reduce costs, and empower builders across DeFi, gaming, enterprise solutions, and beyond.

A Powerful Alliance: OKX Meets Polygon Labs

The partnership between OKX and Polygon Labs unites two major forces in the blockchain space. By leveraging Polygon’s Chain Development Kit (CDK), X1 emerges as OKX’s native ZK-powered network—fully integrated into the Ethereum ecosystem while maintaining sovereignty and scalability.

With over 50 million users on OKX’s platform and a vast global developer community supported by Polygon, this collaboration creates a powerful synergy. It enables seamless access to advanced infrastructure, lowers entry barriers for new projects, and fosters innovation at scale.

This move also underscores OKX’s long-term commitment to contributing directly to Ethereum scaling solutions. As a core contributor to the Polygon CDK initiative, OKX is positioning itself not just as an exchange, but as a foundational builder within the Web3 stack.

X1: Built for Developers, Designed for the Future

At its core, X1 is engineered for developers. From day one, the network has been architected to simplify the deployment and growth of decentralized applications (DApps). Whether you're building in DeFi, NFTs, enterprise blockchain solutions, or Web3 gaming, X1 offers the tools, speed, and cost-efficiency needed to thrive.

One of the standout features is its full compatibility with the Ethereum Virtual Machine (EVM). This means existing Ethereum-based smart contracts can be easily migrated or deployed on X1 without complex rewrites—saving time, reducing risk, and accelerating time-to-market.

Additionally, OKB, OKX’s native platform token, serves as the official gas token on X1. This integration streamlines transaction processing, incentivizes network participation, and strengthens the utility of OKB within a high-performance environment.

Powering Performance with Zero Knowledge Technology

What truly sets X1 apart is its foundation in Zero Knowledge (ZK) proofs—a cryptographic breakthrough that enhances both security and scalability.

ZK technology allows transactions to be validated off-chain while still being secured by Ethereum’s mainnet. This results in:

By utilizing ZK rollups through the Polygon CDK, X1 achieves high throughput without compromising decentralization. This makes it an ideal environment for high-frequency applications like decentralized exchanges (DEXs), real-time gaming, and enterprise-grade systems requiring reliable performance.

Moreover, ZK-powered networks like X1 are paving the way for true interoperability in Web3. In the near future, chains built using CDK could seamlessly communicate, enabling cross-chain asset transfers, shared liquidity pools, and unified user experiences—all while maintaining Ethereum-level security.

Leadership Vision: Bridging Communities and Ecosystems

Leaders from both organizations have emphasized the broader mission behind X1.

Jason Lau, Chief Innovation Officer at OKX, stated that X1 plays a central role in OKX’s strategy to educate and onboard users into Web3. He highlighted the importance of creating intuitive, accessible tools that lower technical barriers for both developers and everyday users.

Meanwhile, Sandeep Nailwal, co-founder of Polygon, praised X1 as an affordable and efficient platform for building decentralized applications. He noted that this collaboration effectively bridges OKX’s massive user base with Ethereum’s robust developer ecosystem, creating fertile ground for innovation and widespread adoption.

Together, their vision reflects a shared goal: to make Web3 more inclusive, performant, and sustainable for the next billion users.

The Rise of Sovereign ZK Layer 2 Networks

The launch of X1 arrives at a pivotal moment in blockchain evolution. With the release of the Polygon CDK in late 2023, enterprises and developers now have the tools to spin up their own sovereign ZK Layer 2 chains on Ethereum—customizable, independent, yet fully secured by Ethereum.

This shift marks a new era of modular blockchain design. Instead of forcing all applications onto a single chain, developers can now create purpose-built networks optimized for specific use cases—whether it’s high-speed trading, private enterprise ledgers, or community-driven social platforms.

Already, projects like Astar and Canto are exploring similar paths using CDK. The coming months are expected to bring more announcements, developer workshops, and ecosystem grants aimed at expanding the ZK L2 landscape.

As stated by Polygon Labs on Twitter:

"Polygon CDK: Your Guide to Sovereign L2 Scaling, From A to ZK. Make your own ZK-powered L2 on Ethereum—in minutes."

This democratization of blockchain infrastructure is exactly what X1 embodies—a sovereign network built for speed, security, and scalability.

Frequently Asked Questions (FAQ)

What is X1?

X1 is a ZK Layer 2 network developed by OKX in collaboration with Polygon Labs. Built using Polygon’s Chain Development Kit (CDK), it operates as a high-performance extension of Ethereum designed to support scalable decentralized applications.

How does X1 improve upon existing Layer 2 solutions?

X1 leverages Zero Knowledge proofs to offer faster transaction finality, lower fees, and enhanced security compared to traditional optimistic rollups. Its EVM compatibility ensures smooth migration for existing DApps.

Is X1 its own blockchain?

Yes—X1 is a sovereign Layer 2 chain with its own governance and economic model. However, it inherits security from Ethereum and remains interoperable with the broader ecosystem.

What role does OKB play on X1?

OKB serves as the native gas token on X1, used to pay for transaction fees and participate in network activities. This expands OKB’s utility beyond trading into core Web3 infrastructure.

Can anyone build on X1?

Absolutely. Developers can deploy EVM-compatible smart contracts on X1 using familiar tools like Hardhat, Remix, and MetaMask. SDKs and documentation will be made available through official channels.

When will X1 be live?

While specific mainnet launch details are forthcoming, testnet access and developer tooling are expected to roll out in phases starting early 2025.
