After successful login, the wallet address will be displayed in the upper right corner of the Bicscan main screen with the network icon selected in the wallet.

### 4. Create BICScan App

In order to perform a scan, whether through the UI or API, an App Key must be created the first time. You can create multiple app keys. Queries executed on the UI will use the first created App key. However, quota allocation/deduction is calculated based on the wallet address, not per app key.

> **Warning**
>
> For security purposes, manage your App Key carefully to ensure that it does not fall into the wrong hands. To replace an App Key, you need to edit the App key and regenerate to a new one.

To create an App Key, please perform the following steps

#### 4.1. Go to Profile

You can view the list of apps you own by clicking on your wallet address in the top right corner and going to Profile in the menu.

You will be asked to sign to verify the wallet user you have connected. No worries, you will not be charged at this stage.

#### 4.2. Creating an App

Click the user addresss in the top right corner, navigate to `Profile` in the menu. In the Profile page, click `Create App` button to create a new app.

#### 4.3. Enter an app name and description

Enter a name for the app being created. While app name and description can be edited later, we recommend using intuitive names like "AppName-Dev", "Application-Backend", and so on.

#### 4.4. Sign to complete app creation

Finally, sign the app to complete its creation.

#### 4.5. Complete

After signing, the new app will be registered on the screen, and you can click on it for more information.
