- 🚀 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, multicall, batching, and persistence
- 🌀 Auto-refresh data on wallet, block, and network changes
- 🦄 TypeScript ready
- 🌳 Test suite running against forked Ethereum network
...and a lot more.

Install wagmi and its ethers peer dependency.
npm install wagmi ethers
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!
