Installation

Install wagmi and its ethers peer dependency.

npm install wagmi ethers

Quick Start

Connect a wallet in under 60 seconds. LFG.

import { Provider, createClient } from 'wagmi'

const client = createClient()

function App() {
  return (
    <Provider client={client}>
      <Profile />
    </Provider>
  )
}

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 (
      <div>
        Connected to {data.address}
        <button onClick={() => disconnect()}>Disconnect</button>
      </div>
    )
  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!
