useWeb3Auth

Core hook that exposes the SDK state and the underlying Web3Auth instance. Use this hook to check whether the user is connected, access the EIP-1193 provider for EVM calls, or access the Solana signer.

Import​

import { useWeb3Auth } from '@web3auth/react-native-sdk'

Usage​

import { useWeb3Auth } from '@web3auth/react-native-sdk'
import { ethers } from 'ethers'
import type { TransactionSigner } from '@solana/signers'

function HomeView() {
  const { isConnected, isInitializing, provider, web3Auth } = useWeb3Auth()

  if (isInitializing) return <Text>Initializing…</Text>
  if (!isConnected) return <Text>Please sign in</Text>

  const getEvmAddress = async () => {
    const ep = new ethers.BrowserProvider(provider!)
    return (await ep.getSigner()).getAddress()
  }

  const getSolanaAddress = () => {
    const signer = web3Auth?.signer as TransactionSigner | null
    return signer ? String(signer.address) : null
  }

  return <View>...</View>
}

Return type​

isConnected​

boolean

true when the user has an active authenticated session. Gates all other hook usage that requires a connected wallet.

isInitializing​

boolean

true while the provider is restoring a previous session on mount. Render a loading indicator while this is true to avoid a flash of the logged-out state.

provider​

IProvider | null

The EIP-1193 compatible provider for the connected EVM chain. Pass this directly to new ethers.BrowserProvider(provider) or createWalletClient({ transport: custom(provider) }) (viem). null when not connected or when the active chain is Solana.

web3Auth​

Web3Auth | null

The underlying SDK instance. Primarily useful for accessing web3Auth.signer on Solana chains and for advanced use cases. Prefer the dedicated hooks for common operations.

signer​

unknown

Alias for web3Auth?.signer. On Solana chains this is a TransactionSigner from @solana/signers. On EVM chains this is null — use provider instead.
