X Layer
X Layer is an Ethereum-compatible Layer 2 blockchain by OKX designed to provide fast, low-cost transactions and scalable infrastructure for Web3 developers.
Overview
X Layer is an Ethereum Virtual Machine (EVM) compatible Layer 2 blockchain developed by OKX to address Ethereum's scalability and cost challenges. It offers developers a platform to build decentralized applications (DApps) with fast transaction speeds, low fees, and high throughput. With an average transaction cost of approximately $0.0005 USD and a block time of 400 milliseconds, X Layer supports around 5,000 transactions per second, making it suitable for a wide range of Web3 use cases including DeFi, NFTs, gaming, and DAOs.
The platform uses OKB as its native gas token, which powers transaction fees and governance mechanisms. X Layer provides a comprehensive ecosystem including a bridge for asset transfers between Ethereum and X Layer, a testnet for development and experimentation, and an explorer to monitor on-chain activity. Its compatibility with Ethereum tooling and standards allows developers to easily port existing Ethereum DApps or build new ones leveraging Layer 2 benefits.
X Layer differentiates itself by combining high performance with minimal transaction costs and a growing community of over 4 million addresses. It integrates with various Web3 services such as wallets (MathWallet), bridges (Meson, Owlto Finance), oracles (Band Protocol), and DeFi protocols (Quickswap, Sizumi Finance). This ecosystem support enables developers to build composable and scalable applications. Getting started involves connecting wallets, using the bridge to transfer assets, and deploying smart contracts on the testnet or mainnet with detailed developer documentation and SDKs provided by OKX.
The Problem
Ethereum's mainnet faces high gas fees, slow transaction speeds, and limited throughput, which hinder the scalability and user experience of decentralized applications. Developers need a solution that maintains Ethereum compatibility while significantly improving performance and cost efficiency.
