This repository contains the documentation for the X Layer blockchain network, an Ethereum Layer 2 solution. It provides educational resources, developer guides, and reference materials for building and interacting with X Layer. The content is organized into sections for developers (including building, deploying, and verifying smart contracts), academy (educational content on blockchain concepts), and various tools and infrastructure available on the network. The documentation follows a structured format using MDX (Markdown with JSX) components, with navigation defined in xlayer-docs.js. It includes tutorials for deploying smart contracts using popular frameworks like Hardhat, Foundry, and Truffle, guides for verifying contracts, explanations of blockchain fundamentals (ERC-20 tokens, Solidity concepts, gas fees), and information about integrating with third-party services such as oracles, node providers, and account abstraction solutions. While the repository contains valuable practical guides and tutorials, it suffers from several quality issues including inconsistent information about the underlying technology stack (referring to both Polygon CDK and Optimism Stack), a critical error in the testnet chain ID in one documentation file, outdated tool version examples, and some placeholder content. These issues reduce its reliability as a sole source of truth, though many of the core tutorials remain useful when cross-referenced with other official sources.
