X Layer is OKX’s EVM-equivalent, zero-knowledge Layer 2 built with Polygon CDK and settled to Ethereum, with OKB as the native gas token. It powers low-cost DeFi, on-chain trading/payments, and gaming/NFT apps integrated with OKX Wallet and Exchange; typical fees are sub-cent (often < $0.001), blocks finalize in ~2s, burst throughput reaches hundreds of TPS, and the network has processed millions of transactions since mainnet.
X Layer is unique in using OKB for gas and in its deep integration with the OKX ecosystem—liquidity from the exchange, fiat on/off-ramps, and seamless wallet UX (including account abstraction)—which drives strong on-chain activity. Built with Polygon CDK with AggLayer interoperability, it combines Ethereum-grade security with fast finality and sub-cent fees; in practice, users see ~2s blocks, hundreds-TPS headroom, and consistently high daily activity while retaining full EVM compatibility.
X Layer uses OKB as the gas token for transaction fees. You can obtain OKB by bridging from other chains or purchasing using thirdweb Bridge.
To bridge OKB to X Layer, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select X Layer as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on X Layer you can use thirdweb, which provides an easy way to build, monetize and scale your apps, games or agents. You can find detailed guides and documentation on https://portal.thirdweb.com to get started quickly.
To add X Layer to your wallet, you can connect your wallet and click on [Add to Wallet] button at the top of the page. Alternatively, you can add the network manually using the RPC URL and chain details and add it to your wallet's network settings.
To send OKB on X Layer, ensure your wallet is connected to the X Layer network, enter the recipient's address, specify the amount of OKB to send, review the gas fee, and confirm the transaction in your wallet.
