OKX Launches ZK-Powered Layer 2 Network X Layer on Public Mainnet

·

The leading cryptocurrency exchange OKX has officially launched X Layer (formerly known as X1), a zero-knowledge (ZK) Layer 2 (L2) network, on its public mainnet. Built using the Polygon Chain Development Kit (CDK), X Layer delivers full EVM compatibility, high performance, and robust security—all while enabling ultra-low transaction fees. This milestone follows the successful testnet rollout in Q4 of the previous year, marking a pivotal step in democratizing access to scalable, secure, and cost-efficient blockchain infrastructure.

With over 200 decentralized applications (dApps) already built on the platform, X Layer is now open to the global community—not just developers. The mainnet launch opens the door for millions of users to experience the power and reliability of a zkEVM-based L2 network designed for real-world adoption.

What Is X Layer? A High-Performance zkEVM L2 Network

X Layer is a next-generation Layer 2 scaling solution that leverages zero-knowledge proofs (ZKPs) to bundle and verify transactions off-chain before finalizing them on the Ethereum mainnet. This architecture dramatically reduces gas costs and latency while preserving Ethereum’s security guarantees.

By achieving 100% EVM compatibility, X Layer ensures that developers can seamlessly port existing Ethereum-based dApps without rewriting code. This lowers entry barriers and accelerates innovation across DeFi, NFTs, gaming, and cross-chain infrastructure.

The network’s foundation on Polygon CDK—a modular framework co-developed by Polygon—to ensure interoperability, composability, and long-term sustainability within the broader Web3 ecosystem.

Seamless Wallet Support and Native Token Integration

X Layer currently supports four major crypto wallets: OKX Wallet, MetaMask, Particle Network, and imToken. This broad compatibility enables both retail users and builders to interact with the network using familiar tools.

A key innovation is the integration of OKB, OKX’s native utility token, as the primary asset for paying transaction fees on X Layer. This creates immediate utility for OKB holders and strengthens the economic alignment between the exchange, its users, and the broader Web3 ecosystem.

Using OKB for gas not only reduces friction but also incentivizes participation. Users who hold or use OKB gain direct benefits from lower costs and enhanced access to emerging dApps built on the network.

Security and Scalability Through Zero-Knowledge Technology

At the heart of X Layer’s architecture is zkEVM technology, which combines the familiarity of Ethereum’s execution environment with the efficiency of ZK rollups. Transactions are processed off-chain and then cryptographically verified through succinct proofs before being posted to Ethereum.

This approach ensures:

ZK proofs eliminate the need for trust assumptions common in other scaling solutions, making X Layer one of the most secure L2 options available at launch.

Strategic Vision: Connecting Millions to Web3

Haider Rafique, Chief Marketing Officer at OKX, emphasized that X Layer is built to onboard over 50 million users into the Web3 economy. With strong community support and deep integration across OKX’s ecosystem—including OKX Exchange and OKX Web3 Wallet—the network is positioned as a central hub for accessible, interconnected digital finance.

"X Layer isn’t just about scaling Ethereum—it’s about scaling access," said Rafique. "Our goal is to make interacting with dApps as fast and affordable as browsing the web."

The network’s connection to Polygon’s AggLayer further amplifies its vision. AggLayer enables unified liquidity and trustless communication across multiple chains, allowing assets and data to move freely between ecosystems without intermediaries.

Marc Boiron, CEO of Polygon, highlighted this synergy: “X Layer’s integration with AggLayer represents a major leap toward a truly unified Web3. It enhances liquidity flow, reduces fragmentation, and accelerates cross-chain innovation.”

Rapid Ecosystem Growth: 200+ dApps at Launch

Since its testnet debut in November 2023, X Layer has seen explosive growth. Over 200 dApps have already been deployed, including industry leaders such as:

This diverse ecosystem signals strong developer confidence and positions X Layer as a fertile ground for innovation in DeFi, identity, gaming, and beyond.

The transition from testnet to mainnet unlocks new opportunities for user engagement, incentivized programs, and deeper integrations across wallets, bridges, and protocols.

Competitive Landscape: The Rise of Exchange-Backed L2s

The launch of X Layer places OKX at the forefront of a growing trend: centralized exchanges building their own L2 networks. This strategic move allows platforms to extend their influence into decentralized infrastructure while offering users seamless on-ramps to Web3.

Other major players have followed similar paths:

These initiatives reflect a broader shift—exchanges are no longer just gateways to crypto but active contributors to blockchain infrastructure.

By launching X Layer, OKX not only strengthens its ecosystem but also fosters greater competition, driving innovation in scalability, usability, and cost-efficiency across the entire industry.

Seamless Integration Across the OKX Ecosystem

One of X Layer’s standout advantages is its native integration with core components of the OKX platform:

This end-to-end synergy lowers adoption barriers for both users and developers, creating a cohesive experience that bridges centralized convenience with decentralized control.
