The decentralized future of Web3 just took a major leap forward with the official launch of X Layer, a cutting-edge Ethereum Layer 2 (L2) network built on ZK technology and powered by Polygon CDK. Announced on April 16, the public mainnet rollout marks a pivotal moment in blockchain scalability, accessibility, and interoperability—ushering in a new era where millions of users can interact with on-chain applications faster, cheaper, and more securely.
Backed by OKX, one of the world’s leading crypto exchanges and Web3 technology innovators, X Layer is engineered to become a foundational infrastructure layer for the next wave of decentralized applications (dApps). With over 50 million users already in OKX’s ecosystem, X Layer enters the market with unprecedented user reach and liquidity potential.
What Is X Layer?
X Layer is an Ethereum Layer 2 scaling solution that leverages zero-knowledge (ZK) rollup technology to deliver high throughput, low transaction fees, and robust security. Built using Polygon’s Chain Development Kit (CDK), it enables developers to rapidly deploy EVM-compatible blockchains that seamlessly integrate with Ethereum’s security model.
One of X Layer’s standout features is its integration with AggLayer, a unified interoperability protocol that allows multiple chains—especially those built with Polygon CDK—to share state and liquidity. This means assets and data can move freely across chains without fragmentation, solving one of Web3’s most persistent challenges: siloed ecosystems.

Seamless Developer Experience & EVM Compatibility
For developers, X Layer removes many of the traditional barriers to blockchain deployment. Since it's fully EVM-compatible, existing dApps built on Ethereum or other EVM-based networks can migrate or deploy with minimal code changes. This dramatically reduces development time and lowers entry barriers for teams looking to scale their applications.
The network supports instant finality and near-instant transaction confirmation, making it ideal for DeFi, NFTs, GameFi, and real-time applications that demand speed and reliability.
Notable projects already active or planning deployment on X Layer include:
- The Graph – For decentralized indexing and querying
- Curve – Leading decentralized exchange for stablecoin swaps
- LayerZero – Omnichain interoperability protocol
- QuickSwap – AMM DEX optimized for speed
- Galxe – Web3 credential and engagement platform
- Timeswap – Decentralized lending and borrowing protocol
With over 170 dApps already accessible via OKX Wallet, users can seamlessly swap tokens, stake assets, explore NFTs, and interact with DeFi protocols—all powered by X Layer’s efficient infrastructure.
A Strong Foundation: 50 Million Users and Growing
OKX brings more than just technical expertise—it brings scale. As one of the largest crypto platforms globally by trading volume (spanning spot and derivatives), OKX manages over $22 billion in crypto assets and serves a global community of more than 50 million users.
This massive user base provides X Layer with immediate network effects. From day one, developers have access to a vast pool of potential users, while users gain frictionless entry into Web3 through OKX Wallet—one of the most advanced self-custody wallets in the space.
OKX Wallet supports 90+ public blockchains, aggregates leading DEXs and NFT marketplaces, and now natively integrates X Layer. This positions it as a true gateway to multichain Web3 experiences.
The Role of OKB: Native Gas Token
The OKB utility token, OKX’s native platform token, serves as the gas currency for X Layer. This means users pay transaction fees in OKB when interacting with dApps on the network. By aligning OKB with core network operations, OKX strengthens token utility and incentivizes broader adoption across its ecosystem.
Powered by Polygon CDK and AggLayer
At its core, X Layer is built using Polygon CDK, a modular framework designed for developers to create customizable, ZK-powered L2s. CDK abstracts away complex cryptographic and consensus layers, allowing teams to focus on building innovative applications rather than reinventing infrastructure.
Moreover, OKX developers are actively contributing to the evolution of Polygon CDK, ensuring continuous improvements in performance, security, and developer tooling.
The integration with AggLayer is another game-changer. Instead of existing as isolated chains, X Layer becomes part of a unified network of interoperable blockchains—all sharing liquidity and state. This eliminates cross-chain friction and opens up new possibilities for omnichain applications.
Marc Boiron, CEO of Polygon Labs, emphasized this vision:
“X Layer represents a milestone toward a truly unified Web3. By connecting to AggLayer, it solves liquidity fragmentation and unlocks shared growth. With OKX’s 50 million users now able to access this ecosystem effortlessly, we’re accelerating mass adoption.”
Rapid Adoption Since Testnet Launch
Even before the public mainnet launch, X Layer demonstrated strong momentum. Since its testnet went live in November 2023, over 50 Web3 projects deployed on the network within just one week. The vibrant developer community reflects confidence in X Layer’s architecture, performance, and long-term viability.
As mainnet goes live, expectations are high for exponential growth in both user activity and dApp innovation.

Why X Layer Matters for Web3’s Future
Scalability has long been the bottleneck holding back mainstream blockchain adoption. High fees and slow confirmations on Ethereum have limited access for average users. X Layer addresses these pain points head-on by offering:
- Low-cost transactions: Enabled by ZK rollups
- High-speed processing: Near-instant finality
- Security: Inherits Ethereum’s robust consensus
- Interoperability: AggLayer enables seamless cross-chain flow
- Developer-friendly tools: Fast deployment via Polygon CDK
Together, these features make X Layer not just another L2—but a strategic piece of Web3’s evolving infrastructure.
