The Wallet Integration Guide (PDF) is an in-depth offline resource created to help developers, product managers, and tech-savvy entrepreneurs successfully integrate popular crypto wallets into their decentralized applications (dApps). Whether you're building an NFT platform, DeFi protocol, DAO dashboard, or Web3 marketplace, this guide walks you through the full process of wallet connectivity with a focus on security, UX, and compatibility. The guide covers integration steps for top wallets such as MetaMask, Trust Wallet, WalletConnect, Phantom, and Ledger. It also provides code snippets, configuration examples, and architecture flow diagrams tailored for frameworks like React, Next.js, and Web3.js. Key topics include multi-wallet support, session management, user address retrieval, handling network switching, and dealing with signature requests. Special attention is given to best practices like onboarding fallback mechanisms, gas fee visibility, mobile responsiveness, and safe disconnect features. For Japanese developers, localized notes and code comments enhance understanding of complex implementations. The guide also includes troubleshooting tips for common errors like “User Rejected Request,” “Provider Not Found,” and “Chain ID Mismatch.” Bonus content provides design checklists to ensure wallet buttons and UI flows meet standard usability expectations. The Wallet Integration Guide is ideal for developers working on MVPs, hackathon projects, or production-level dApps, offering a complete technical reference without relying on constant internet access. The downloadable PDF format allows for convenient offline use during development or team code reviews.
