The blockchain ecosystem continues to evolve at a rapid pace, with innovation driving scalability, security, and user accessibility. In a significant leap forward, OKX and Polygon Labs have officially launched the testnet for X1, a cutting-edge zero-knowledge (ZK) Layer 2 network built to enhance Ethereum’s performance and expand its real-world utility. This collaboration marks a pivotal moment in the evolution of decentralized infrastructure, combining OKX’s vast user base with Polygon’s proven development toolkit.
Introducing X1: A New Era for Ethereum Scaling
At the heart of this advancement is X1, a ZK-powered Layer 2 solution designed to address Ethereum’s longstanding challenges—high gas fees, network congestion, and slow transaction speeds. By leveraging zero-knowledge proofs, X1 ensures faster, more secure, and cost-efficient transactions while maintaining full compatibility with the Ethereum Virtual Machine (EVM).
What sets X1 apart is its foundational integration with the Polygon Chain Development Kit (CDK). This modular framework enables teams to rapidly deploy customizable Layer 2 and Layer 3 blockchains on Ethereum. OKX has emerged as a key contributor to the CDK ecosystem, dedicating significant engineering resources to accelerate development and drive broader adoption.

With X1, OKX is not just building infrastructure—it’s expanding the utility of its native platform token, OKB. Starting with the testnet phase, OKB will serve as the primary token for paying transaction fees on X1. This strategic move enhances OKB’s real-world use case, positioning it at the core of a growing on-chain ecosystem.
Seamless Integration for Developers and Users
One of X1’s most compelling features is its EVM compatibility. This means developers can effortlessly deploy existing smart contracts, decentralized applications (DApps), wallets, and developer tools without complex rewrites or adjustments. For users, this translates into a familiar, intuitive experience—no learning curve, no friction.
The network is engineered to support:
- Instant transaction finality
- Ultra-low gas costs
- High throughput for consumer-grade applications
- Cross-chain interoperability
This combination makes X1 an ideal platform for building and scaling Web3 applications that demand performance without compromising decentralization or security.
Jason Lau, Chief Innovation Officer at OKX, emphasized X1’s role in democratizing access to Web3:
“X1 is designed to be a gateway for millions of users to enter the decentralized world. We’re empowering developers to build consumer-first applications while ensuring seamless connectivity across chains.”
Powering the Future with Zero-Knowledge Technology
Zero-knowledge proofs are no longer just theoretical—they’re becoming foundational to scalable blockchain design. X1 leverages ZK-rollup technology to bundle thousands of transactions off-chain and submit cryptographic proofs to Ethereum for verification. This drastically reduces on-chain data load while preserving trustlessness and security.
The benefits are clear:
- Enhanced Security: Inherits Ethereum’s robust consensus mechanism
- Lower Costs: Minimizes gas fees through efficient data compression
- Greater Scalability: Supports high-volume applications like gaming, DeFi, and social platforms
By integrating ZK technology at its core, X1 aligns with the long-term vision of a unified, global on-chain economy—one where users and developers can interact securely and efficiently across networks.
A Strategic Collaboration Between Industry Leaders
The partnership between OKX and Polygon Labs represents more than just technical synergy—it reflects a shared commitment to open innovation and ecosystem growth. Polygon Labs’ CDK, first released in August 2023, has already empowered numerous projects to launch their own app-specific or enterprise-grade Layer 2 solutions.
OKX’s involvement signals strong institutional support for modular blockchain development. With over 50 million users in its ecosystem, OKX brings not only technical expertise but also a massive potential user base ready to engage with X1-powered applications.
This collaboration sets a new benchmark for how centralized platforms and decentralized infrastructure teams can co-develop solutions that benefit the broader Web3 community.
