The Web3 landscape has taken a significant leap forward with the official launch of X Layer, a cutting-edge Ethereum Layer 2 network developed by OKX, one of the world’s leading cryptocurrency exchanges and Web3 technology innovators. Announced on April 16, the public mainnet rollout marks a pivotal moment in blockchain scalability, accessibility, and mass adoption.
Built on ZK (Zero-Knowledge) technology using the Polygon CDK (Chain Development Kit), X Layer is engineered to deliver fast, secure, and low-cost transactions while maintaining full compatibility with the Ethereum Virtual Machine (EVM). This means developers can seamlessly deploy existing Ethereum-based dApps with minimal modifications—accelerating innovation and reducing time-to-market.

A High-Performance Infrastructure for the Next Era of Web3
At its core, X Layer aims to solve two of the most persistent challenges in blockchain: high transaction fees and network congestion. By leveraging ZK rollup technology, it bundles thousands of transactions off-chain and submits cryptographic proofs to Ethereum, ensuring security without sacrificing speed or cost-efficiency.
But X Layer goes beyond just performance. It introduces seamless interoperability through AggLayer, a unified aggregation layer that enables shared state and liquidity across multiple chains built on Polygon CDK. This interconnected design eliminates liquidity silos, allowing assets and data to flow freely between chains—paving the way for a truly unified Web3 ecosystem.
“X Layer is built for visionary developers creating applications that bring millions onto the blockchain,” said Haider Rafique, Chief Marketing Officer at OKX. “Think of Layer 2s as highways in the Web3 world—dApps are the destinations, and self-custody wallets are the vehicles. We’re building an ecosystem that’s as seamless and interoperable as possible.”
Rapid Adoption and Developer Momentum
Even before its public mainnet launch, X Layer demonstrated strong traction. Since the testnet went live in November 2023, over 50 Web3 dApps deployed within the first week alone. Notable projects include The Graph, Curve, LayerZero, QuickSwap, Galxe, and Timeswap, all signaling confidence in X Layer’s technical foundation and long-term potential.
Today, users can already:
- Transfer assets across the X Layer network
- Deposit and withdraw crypto via OKX
- Interact with more than 170 dApps for swapping, staking, lending, and NFT trading
With the public mainnet now live, this momentum is expected to accelerate exponentially. The growing developer community sees X Layer not just as another L2, but as a scalable, secure, and interconnected platform capable of supporting next-generation decentralized applications.

Powering Mass Adoption: 50 Million Users and Beyond
One of X Layer’s most compelling advantages is its direct integration with OKX’s massive user base—over 50 million global users. As one of the largest crypto exchanges by trading volume (including spot and derivatives), OKX brings unparalleled liquidity and reach to the network from day one.
Additionally, OKX Wallet, recognized as one of the most advanced Web3 gateways, supports over 90 public blockchains and features powerful DEX and NFT aggregators. This deep integration ensures that millions of users can access X Layer with ease—no complex setups or technical barriers.
The network’s native utility token? OKB, OKX’s platform token, will be used to pay gas fees on X Layer, further enhancing its utility and reinforcing network security.
Backed by Polygon CDK and AggLayer Innovation
X Layer is powered by Polygon CDK, a state-of-the-art software development kit tailored for ZK-based blockchain builders. The CDK simplifies the creation of customizable, Ethereum-aligned Layer 2s—enabling faster deployment, improved security, and modular scalability.
OKX developers are actively contributing to the evolution of Polygon CDK, ensuring continuous innovation in core infrastructure. Moreover, through AggLayer, X Layer connects with other CDK-powered chains, enabling cross-chain communication with shared liquidity and unified security—a critical step toward eliminating fragmentation in Web3.
Marc Boiron, CEO of Polygon Labs, emphasized the strategic importance:
“X Layer represents a landmark step toward a truly unified Web3. Its integration with AggLayer solves the critical issue of liquidity fragmentation across chains. With over 50 million OKX users now able to access X Layer and connected networks, we’re unlocking unprecedented growth potential. The strong developer interest proves this network’s promise—and we look forward to advancing our shared vision with OKX.”
