Web3 Frontend

pluginagentmarketplace/custom-plugin-blockchain

This is your goto for building dApp frontends with wagmi and viem. It covers the full stack: wallet connection with RainbowKit, transaction management with proper pending states, EIP-712 signing for gasless approvals, and all the React hooks you actually need. The examples are production-ready, showing real patterns like error parsing for user-friendly messages and SSR handling in Next.js. Honestly, the skill shines because it focuses on the annoying parts that trip people up, like hydration errors and BigInt serialization, rather than just repeating the docs. If you're building anything that touches MetaMask or WalletConnect, this will save you from reinventing wallet UX for the hundredth time.
