# Create Smart Contract Wallet

### Initialization

The `init` method is a fundamental feature of the SDK that enables you to setup a wallet & authenticate the user's provided credentials. The method requires the use of a `PRIVATE_KEY` which you can get in the Fuse Developer Console [here](https://console.fuse.io/build). When you send a request to the server using this method, it verifies the credentials and if the credentials are valid, developers can use the **`getSender()`** to return an address.

  <PlatformTabItem value="web">
    ```typescript theme={null}
    import {ethers} from "ethers";
    import {FuseSDK} from "@fuseio/fusebox-web-sdk";

    const apiKey = "API_KEY";
    const credentials = new ethers.Wallet("PRIVATE_KEY");
    const fuseSDK = await FuseSDK.init(apiKey, credentials);
    ```

    ### **Access the wallet**

    ```dart theme={null}
    // Create Wallet
    const smartContractAddress = fuseSDK.wallet.getSender();
    console.log(`Sender Address is ${smartContractAddress}`);
    ```
  </PlatformTabItem>

  <PlatformTabItem value="flutter">
    ```dart theme={null}
    //Enter your Fuse Developer API Key
    final apiKey = 'API_KEY';

    // Generate a random Ethereum private key
    final String privateKey = await Mnemonic.generatePrivateKey();
    final EthPrivateKey credentials = EthPrivateKey.fromHex(privateKey);

    final fuseSDK = await FuseSDK.init(apiKey, credentials);
    ```

    ### **Access the wallet**

    ```dart theme={null}
    // Create Wallet
    final smartContractAddress = fuseSDK.wallet.getSender();

    print('Smart contract wallet address: $smartContractAddress');
    ```
