Crypto exchange OKX has officially launched its Layer-2 blockchain, X Layer, on the public mainnet. X Layer, previously known as X1, is built using Polygon’s Chain Development Kit (CDK) with zero-knowledge technology for developers to create custom chains.

The “X” in the name symbolizes openness and interoperability, while “LAYER” represents different protocols enhancing blockchain scalability. Major exchanges like Coinbase and Kraken are also exploring their layer-2 networks.

Per OKX’s press release, developers will actively contribute to the CDK codebase, integrating X Layer with Polygon’s ecosystem through AggLayer. This allows OKX’s 50 million users to easily access X Layer and other chains.

X Layer, initially launched on a testnet, currently supports over 170 dapps, with plans for more in the future. The network aims to be foundational for the web3 ecosystem, likening layer-2 chains to highways for dApp and self-hosted wallet access.

OKX’s introduction of X Layer aligns with its focus on compliance activities in the US. Amid regulatory concerns, OKX removed USDT from its European services and froze USDT assets in partnership with Tether.
