# useWeb3Auth

Hook to access the Web3Auth context.

### Import

```tsx
import { useWeb3Auth } from '@web3auth/modal/react'

```

### Usage

```tsx
import { useWeb3Auth } from '@web3auth/modal/react'

function App() {
  const { web3Auth, isConnected, isInitializing, connection, status, initError } = useWeb3Auth()

  if (isConnected) {
    console.log('Connected via:', connection?.connectorName)
  }
  if (isInitializing) {
    console.log('Web3Auth is initializing')
  }
  if (connection?.ethereumProvider) {
    // Use for JSON-RPC edge cases; prefer Wagmi hooks for standard EVM flows
    console.log('Ethereum provider available')
  }
  if (status) {
    console.log('Web3Auth status:', status)
  }
  if (initError) {
    console.log('Web3Auth initialization error:', initError)
  }
}

```

info

For EVM wallet operations, use [Wagmi hooks](/embedded-wallets/sdk/react/ethereum-hooks/) (`useConnection`, `useBalance`, `useSendTransaction`) after setting up `WagmiProvider`. Use `connection.ethereumProvider` only for JSON-RPC methods Wagmi does not cover. See the [Web SDK v11 migration guide](/embedded-wallets/migration-guides/web/#provider-api-changes-all-frameworks).
