You can also use Privy to connect a user’s external wallet if they have one, or to create an embedded wallet for them if they do not. This ensures users always have a connected wallet they can use with your application, and allows them to choose to use their external wallet if preferred. To do so, use the **`connectOrCreateWallet`** method of the **`usePrivy`** hook: ```tsx theme={"system"} const {connectOrCreateWallet} = usePrivy(); ``` This method will prompt the user to connect an external wallet, or log in with email, SMS, or socials, depending on your configured `loginMethods`, to create an embedded wallet. Privy’s `connectOrCreate` interface currently only supports external and embedded wallets on EVM networks. For example, you might have a “Connect” button in your app that prompts users to connect their wallet, like so: ```tsx theme={"system"} import {useConnectOrCreateWallet} from '@privy-io/react-auth'; export default function ConnectWalletButton() { const {connectOrCreateWallet} = useConnectOrCreateWallet(); // Prompt user to connect a wallet with Privy modal return ; } ``` This method functions exactly the same as Privy’s `login` method, except when users connect their external wallet, they will not automatically be prompted to authenticate that wallet by signing a message Callbacks You can optionally pass callbacks to the `useConnectOrCreateWallet` hook to run custom logic after connecting a wallet or to handle errors. `onSuccess` ```tsx theme={"system"} onSuccess: (args: {wallet: ConnectedWallet}) => Promise; ``` ##### Parameters The most recently connected wallet. `onError` ```tsx theme={"system"} onError: (error: Error) => Promise; ``` ##### Parameters The error that occurred during the this flow.
