# getWallet

> Retrieves wallet information for an existing user by their external user ID. This method allows you to fetch wallet details for users who have already created wallets.

## Usage

```typescript theme={null}
const bearerToken = await getBearerToken(); // Your auth implementation

const wallet = await browserClient.getWallet({
  externalUserId: "your-user-id-123",
  bearerToken: bearerToken,
});
```

### Parameters

* `externalUserId` (string): Your application's unique identifier for the user
* `bearerToken` (string): Bearer token for authentication

### Return Value

Returns a Promise that resolves to an object containing:

* `publicKey` (string): The wallet's public address on StarkNet
* `encryptedPrivateKey` (string): The encrypted private key for the wallet

## Example Implementation

```typescript theme={null}
import { ChipiBrowserSDK } from "@chipi-stack/backend";

const browserClient = new ChipiBrowserSDK({
  apiPublicKey: process.env.VITE_CHIPI_PUBLIC_KEY, // or your framework's env var
});

async function getUserWallet(userId: string) {
  try {
    const bearerToken = await getBearerToken(); // Your auth implementation
    
    const wallet = await browserClient.getWallet({
      externalUserId: userId,
      bearerToken: bearerToken,
    });

    console.log('Wallet found:');
    console.log('Address:', wallet.publicKey);
    
    return wallet;
  } catch (error) {
    if (error.message.includes('not found')) {
      console.log('No wallet found for user:', userId);
      return null;
    }
    
    console.error('Error retrieving wallet:', error);
    throw error;
  }
}

// Usage example
async function checkUserWallet(userId: string) {
  const wallet = await getUserWallet(userId);
  
  if (wallet) {
    console.log(`User ${userId} has wallet: ${wallet.publicKey}`);
    return wallet;
  } else {
    console.log(`User ${userId} needs to create a wallet`);
    return null;
  }
}
```
