OKX, a centralized cryptocurrency exchange, unveiled the public mainnet of X Layer, an Ethereum-based zero-knowledge Layer 2 network powered by the Polygon Chain Development Kit, on Monday evening.

Haider Rafique, CMO of OKX, expressed the company's vision for X Layer as a fundamental infrastructure for the Web3 era, likening it to highways, dApps to marketplaces, and self-hosted wallets to vehicles.

X Layer, formerly known as "X1," debuted on testnet in November, witnessing rapid adoption with over 50 decentralized applications launching within a week. Notable Web3 and DeFi apps like The Graph, Curve, LayerZero, QuickSwap, Galxe, and Timeswap have already embraced this Layer 2 network.

X Layer enables users to deposit and withdraw cryptocurrencies via OKX, granting access to a diverse array of over 170 dApps for token swaps, staking, and other smart contract functionalities. With a user base of 50 million global users and abundant liquidity, X Layer is poised for substantial growth.

OKX has designated its platform token, OKB, as the native asset for transaction fee payments on the X Layer network. Leveraging Polygon's CDK, X Layer utilizes ZK rollup technology to enhance transaction throughput, reduce costs, and maintain Ethereum's network security. As an EVM-compatible solution, X Layer simplifies the deployment of existing Ethereum-based apps on Layer 2 without necessitating significant development efforts.

The Polygon CDK, released by Polygon Labs in August 2023, has attracted various projects like Immutable, Astar, Canto, Palm Network, Aavegotchi, IDEX, Nubank, and Manta Network, which are either utilizing or planning to use it for developing their Layer 2 networks.

X Layer will be interconnected with other Polygon CDK-powered networks via its blockchain aggregation layer, AggLayer, facilitating shared state and unified liquidity across multiple chains. Polygon Labs CEO Marc Boiron hailed X Layer as a pivotal advancement towards a cohesive Web3 ecosystem, emphasizing its role in overcoming liquidity fragmentation and providing a seamless onboarding experience for OKX's vast user base.
