OKX, a leading global virtual asset exchange and Web3 technology company, has officially launched the X Layer public mainnet. X Layer is an Ethereum Layer-2 (L2) network powered by zero-knowledge (ZK) technology, built with Polygon CDK, and designed to enable shared liquidity and state across chains via AggLayer — combining innovation with robust security.
Key Features of X Layer
- Cost-Efficient Transactions: Leverages ZK proofs to reduce fees while maintaining security
- EVM Compatibility: Seamlessly supports Ethereum-based dApps with minimal development overhead
- Scalability: Processes high throughput via Polygon CDK’s modular architecture
- Interoperability: Integrates with AggLayer for cross-chain liquidity pooling

Developer-Centric Infrastructure
Haider Rafique, OKX Chief Marketing Officer, emphasizes:
"X Layer is built for visionary developers creating apps to onboard millions to Web3. Think of it as infrastructure highways where dApps are marketplaces, and self-custody wallets are the vehicles. Our goal is a seamless, interoperable ecosystem."
Rapid Adoption and Ecosystem Growth
Since its testnet launch in November 2023, X Layer has seen explosive adoption:
- 50+ dApps deployed within a week (e.g., The Graph, Curve, QuickSwap)
- 170+ dApps now live, enabling swaps, staking, and more via smart contracts
- OKB token serves as the native gas fee currency
With OKX’s 50 million users and $22B+ in assets under custody, X Layer launches with built-in liquidity and a vast user base.
Technological Backbone: Polygon CDK & AggLayer
- Polygon CDK: ZK-based toolkit for customizable L2 chains
- AggLayer Integration: Enables cross-chain atomic composability
Marc Boiron, CEO of Polygon, states:
"X Layer’s connection to AggLayer solves liquidity fragmentation, allowing OKX’s users to access all connected chains. This is a milestone for unified Web3."
FAQ Section
What makes X Layer different from other L2s?
X Layer uniquely combines ZK proofs with AggLayer interoperability, offering low-cost transactions and shared liquidity across multiple chains.
How can developers deploy dApps on X Layer?
EVM compatibility allows Ethereum developers to port existing dApps with minimal changes. New projects can use Polygon CDK for customized L2 solutions.
Is OKB required to use X Layer?
Yes, OKB is the network’s native token for gas fees, incentivizing ecosystem participation.
