OKX launches its own second-layer network, joining Immutable and others in the growing Polygon ecosystem.

Cryptocurrency exchange OKX has launched the mainnet of its Ethereum-based zero-knowledge second-layer network X Layer. Haider Rafique, Chief Marketing Officer of OKX, said: "We see X Layer and other second-layer chains as the highway infrastructure of the Web3 world. To achieve this vision, we are building an ecosystem that is as seamless and interoperable as possible."
The mainnet launch follows the launch of the testnet last November. In the first week after the testnet went live, more than 50 decentralized applications were deployed on the testnet, and the OKX team now hopes to carry this momentum over to the mainnet.
Decentralized applications such as The Graph, LayerZero, Curve, QuickSwap, Timeswap, and Galxe have already begun to utilize this second-layer network.
X Layer’s mainnet launch gives users access to over 170 decentralized applications and the ability to deposit and withdraw cryptocurrencies through OKX.
As OKX has 50 million users worldwide, X Layer already has a huge potential user base and abundant liquidity resources.
The company also confirmed that OKX’s native token, OKB, will also become a utility token in the second-layer network. This means that transaction fees on the chain will be paid in OKB.
X Layer will also connect with other networks powered by Polygon’s CDK, which the team used to develop the network.
As a result, X Layer will be able to connect with networks that use or plan to use CDK to develop their own second-layer networks, such as Immutable, Astar, Canto, Palm Network, Aavewotchi, IDEX, Manta Network, and Nubank. Through Polygon's "AggLayer", X Layer will gain unified liquidity across multiple chains.
“X Layer is an important step for the industry to build a truly unified Web3,” said Marc Boiron, CEO of Polygon Labs. “The connection between X Layer and AggLayer solves the liquidity and user fragmentation issues on AggLayer, allowing them to grow together.”
