OKX Unveils ZK Layer 2 Network X Layer on Public Mainnet

·

The cryptocurrency landscape continues to evolve at a rapid pace, and OKX has just taken a major leap forward with the official mainnet launch of X Layer, its highly anticipated zero-knowledge (ZK) layer 2 (L2) network. Formerly known as X1, X Layer is now live on the public mainnet, marking a pivotal moment in the exchange’s expansion beyond trading into decentralized infrastructure.

Built using the Polygon Chain Development Kit (CDK), X Layer is engineered for seamless integration with the Ethereum ecosystem. The network promises full EVM (Ethereum Virtual Machine) compatibility, enabling developers to deploy existing Ethereum-based dApps with minimal modifications. This strategic design choice significantly lowers the barrier to entry for builders while ensuring robust performance, enhanced security, and remarkably low transaction fees.

Seamless Wallet Integration and Native Token Utility

From day one of its mainnet launch, X Layer supports integration with four leading crypto wallets: OKX Wallet, MetaMask, Particle Network, and imToken. This broad compatibility ensures immediate accessibility for millions of users already active in the Web3 space.

A key highlight is the use of OKB, OKX’s native utility token, as the primary asset for paying gas fees on X Layer. This move not only strengthens the utility of OKB but also creates a direct economic incentive for users and developers to engage with the OKX ecosystem.

Powering the Future of Web3 with ZK Technology

At the heart of X Layer’s architecture lies zero-knowledge proof technology, a cutting-edge cryptographic method that enables high scalability without compromising security. By batching transactions off-chain and submitting compact validity proofs to Ethereum, ZK rollups like X Layer drastically reduce congestion and costs while maintaining decentralization.

This technological foundation allows X Layer to deliver near-instant transaction finality and unified liquidity across connected chains—two critical components for a truly interoperable Web3 economy.

Haider Rafique, Chief Marketing Officer at OKX, emphasized the network’s vision:

“X Layer is for visionary builders who are creating applications to help bring millions of people on-chain. We think X Layer has limitless potential thanks to our strong community and its connectivity with other Ethereum-based networks.”

Bridging Ecosystems Through AggLayer

One of X Layer’s most strategic advantages is its integration with AggLayer, Polygon’s ambitious aggregation protocol designed to unify multiple blockchains into a single, cohesive settlement layer. This connection enables seamless communication and liquidity sharing between X Layer and other Ethereum-compatible networks.

Marc Boiron, CEO of Polygon, underscored the significance:

“X Layer is a monumental next step in the industry's ambition to build a truly unified Web3. The X Layer's connection to the AggLayer solves the fragmentation of liquidity and users across chains on the AggLayer so they can all grow together.”

This cross-chain synergy positions X Layer not just as an isolated L2 solution, but as a vital node in an expanding Web3 infrastructure network.

Explosive Ecosystem Growth Since Testnet Launch

Even before its mainnet debut, X Layer demonstrated strong market traction. Since its beta launch in November 2023, over 200 Web3 dApps have deployed or announced plans to integrate with the platform. Notable projects include:

This early adoption reflects growing confidence among developers in X Layer’s performance, reliability, and long-term viability.

User-Centric Design: Bridging Assets with Ease

To ensure a frictionless experience, X Layer is natively integrated with both the OKX Exchange and the OKX Web3 Wallet. Users can now bridge assets between these platforms effortlessly—moving funds from centralized accounts to on-chain applications within minutes.

Such integration streamlines onboarding for newcomers while empowering experienced traders and DeFi users to manage their portfolios across centralized and decentralized environments efficiently.

Fueling Innovation: A Developer-First Approach

With the mainnet now live, OKX is intensifying efforts to attract developers and expand the dApp ecosystem on X Layer. The goal is clear: unlock the full potential of ZK and L2 technologies by fostering innovation through grants, developer tools, documentation, and community support.

By offering a blazing-fast, cost-effective, and secure environment, X Layer aims to become a go-to platform for creators building the next generation of decentralized applications—from gaming and social networks to DeFi and NFT marketplaces.

Shaping the Competitive L2 Landscape

OKX’s entry into the L2 arena adds momentum to an increasingly competitive space. With Coinbase launching Base (built on Optimism’s OP Stack) in mid-2023 and Kraken reportedly developing its own L2 solution, major exchanges are now investing heavily in blockchain infrastructure.

X Layer differentiates itself through its ZK-based architecture, EVM compatibility, and deep integration with Polygon’s AggLayer—offering a compelling alternative for developers seeking scalability without sacrificing security or decentralization.
