Discover X Layer, a blockchain platform designed for decentralized applications. Build secure and scalable dApps with its developer-friendly SDK.
The X Layer RPC documentation provides developers with the tools to interact with the X layer blockchain. X Layer is a high-performance Ethereum Layer 2 (L2) network built by OKX using the Polygon CDK and Optimism Stack technology. It offers fast, secure, and low-cost transactions (using OKB for gas) for decentralized applications (dApps). It boasts full EVM equivalence, allowing developers to deploy existing Solidity contracts with minimal changes.
