X Layer (OKB)

What is X Layer?​

X Layer is an Ethereum Layer 2 network created by OKX in collaboration with Polygon Labs. It uses Polygon CDK and is designed to bring OKX users, developers, and applications into an EVM-compatible onchain ecosystem.

Here are 5 key points about X Layer:

  • OKB is the native token used to pay network fees on X Layer.

  • X Layer supports Ethereum-style addresses, smart contracts, and ERC20 tokens.

  • Transactions are designed to be faster and cheaper than using Ethereum mainnet directly.

  • Users can move supported assets on X Layer while keeping familiar EVM wallet behavior.

  • Developers can build DeFi, payment, and token applications with common Ethereum tooling.
