React Hooks for Ethereum

wagmi is a collection of React Hooks containing everything you need to start working with Ethereum. wagmi makes it easy to "Connect Wallet," display ENS and balance information, sign messages, interact with contracts, and much more — all with caching, request deduplication, and persistence.

npm i wagmi ethers


import { Provider, createClient } from 'wagmi'

const client = createClient()

function App() {
  return (
    <Provider client={client}>
      <Profile />
import { useAccount, useConnect, useDisconnect } from 'wagmi'
import { InjectedConnector } from 'wagmi/connectors/injected'

function Profile() {
  const { data } = useAccount()
  const { connect } = useConnect({
    connector: new InjectedConnector(),
  const { disconnect } = useDisconnect()

  if (data)
    return (
        Connected to {data.address}
        <button onClick={() => disconnect()}>Disconnect</button>
  return <button onClick={() => connect()}>Connect Wallet</button>

In this example, we create a wagmi Client and pass it to the React Context Provider. Next, we use the useConnect hook to connect an injected wallet (e.g. MetaMask) to the app. Finally, we show the connected account's address with useAccount and allow them to disconnect with useDisconnect.

We've only scratched the surface for what you can do with wagmi!


wagmi supports all these features out-of-the-box:

  • 20+ hooks for working with wallets, ENS, contracts, transactions, signing, etc.
  • Built-in wallet connectors for MetaMask, WalletConnect, Coinbase Wallet, and Injected
  • Caching, request deduplication, and persistence
  • Auto-refresh data on wallet, block, and network changes
  • TypeScript ready
  • Test suite running against forked Ethereum network

...and a lot more.
