wagmi is a React library for Ethereum application frontends. It provides typed hooks and connectors for accounts, wallets, contract calls, transaction flows, signing, ENS data, and chain state.

Use it for:

• Connecting wallets such as MetaMask, WalletConnect, Coinbase Wallet, and injected wallets.
• Reading and writing smart contracts from React apps.
• Managing transaction receipts, network switching, and wallet state.
• Caching blockchain requests through TanStack Query.

Best fit: DApp teams that need a practical frontend layer for wallet and RPC state handling.
