# Customize Your Username, Avatar, and Demo Balance

> Update your username, avatar, and demo wallet balance from the Settings tab. Changes to your username are reflected immediately on the leaderboard.

The Settings tab is your control panel for personalizing your Quantum Finance account. From here you can update your display name, swap your avatar, inspect your wallet address, and manage your demo wallet balance for practice trading. Your wallet address is tied to your Web3Auth session and is always read-only — it cannot be edited from this screen.

## Change your username

Your username appears on the leaderboard and across the app. You can update it at any time.

<Steps>
  <Step title="Open Settings">
    Navigate to the **Settings** tab from the main navigation bar.
  </Step>

  <Step title="Edit your username">
    Click the username input field under **Profile Settings** and type your new display name.
  </Step>

  <Step title="Save your changes">
    Click **Save Profile**. The button shows "Saving…" while the update is in progress. Once it completes, your new username is live.
  </Step>
</Steps>

<Note>
  Your updated username appears on the global leaderboard immediately after saving.
</Note>

## Change your avatar

You have two ways to update your profile picture.

### Choose a preset avatar

Quantum Finance includes 100 preset avatars generated in the DiceBear Avataaars style.

<Steps>
  <Step title="Open the avatar picker">
    Click the **camera icon** in the bottom-right corner of your current avatar. The avatar picker modal opens.
  </Step>

  <Step title="Select an avatar">
    Browse the grid of 100 avatars and click any one to apply it instantly. Your current avatar is highlighted with a checkmark.
  </Step>
</Steps>

### Upload a custom image

<Steps>
  <Step title="Trigger the upload">
    Hover over your avatar and click the **upload icon** that appears over the image.
  </Step>

  <Step title="Select an image file">
    Choose any image file from your device. The app accepts standard image formats.
  </Step>

  <Step title="Review the crop preview">
    A preview modal appears showing how your image will be cropped and scaled to fit a circular profile picture. Quantum Finance auto-scales the image for you.
  </Step>

  <Step title="Apply and save">
    Click **Apply & Save** to upload your image. A progress bar shows the upload status. Click **Cancel** to discard the change.
  </Step>
</Steps>

## Wallet address

Your connected wallet address is displayed in the **Wallet Address** field below your username. This value is read-only and reflects the wallet linked to your Web3Auth session. It cannot be changed from the Settings tab.

## Demo wallet controls

The **Demo Wallet Controls** section lets you manage your paper-trading balance so you can test strategies without real funds on the line.

| Action | What it does |
| - | - |
| **Add Funds** | Adds \$5,000 USDT to your current demo balance |
| **Reset Balance** | Sets your demo balance back to \$10,000 |
| **Empty Wallet** | Sets your demo balance to \$0 — useful for testing how the engine behaves with no available capital |

<Tip>
  Use **Empty Wallet** before a practice run to simulate starting from zero, then use **Add Funds** to top up in \$5,000 increments as needed.
</Tip>

## Sign out

To sign out of Quantum Finance, scroll to the bottom of the **Security & Account** section and click **Logout**. This ends your session and returns you to the login screen.
