Installation

Install wagmi and its ethers peer dependency.

npm install wagmi ethers

Quick Start

Connect a wallet in under 60 seconds. LFG.

import { WagmiConfig, createClient } from 'wagmi'
import { getDefaultProvider } from 'ethers'

const client = createClient({
  autoConnect: true,
  provider: getDefaultProvider(),
})

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

import { useAccount, useConnect, useDisconnect } from 'wagmi'
import { InjectedConnector } from 'wagmi/connectors/injected'

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

  if (address)
    return (
      <div>
        Connected to {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 WagmiConfig React Context. The client is set up to use the ethers Default Provider and automatically connect to previously connected wallets.

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!
