*** ## Exchanging In-app Currency and gMBX Now that we’re connected to the game, let’s take a look at how to exchange In-app Currency with gMBX. 1. From the main page of MBX Station, hover your mouse over a game and click Go to Exchange.

2. The exchange interface is on the right. Let’s explore how it works.

3. Choose the direction of the exchange. If you want to exchange In-app Currency for gMBX, select an In-app Currency from the "From" dropdown menu.

{% hint style="info" %} In the image above, the **World Fighting Championship Key** is the In-app Currency. {% endhint %} 4. Enter the amount you want to exchange, and the output value (gMBX) will be automatically calculated based on the current exchange rate.

{% hint style="warning" %} The exchange fee may be charged in In-app Currency or gMBX and is calculated using the AMM method. In-app **Currency** can be purchased in-game. When gMBX is used as the exchange fee, it won’t appear in the "Estimated Rate," but a certain amount will be deducted at the Confirm Exchange stage. {% endhint %} 5. Next, click the Terms of Service button. Read through the Terms & Conditions and click Agree.

6. After agreeing to the terms and conditions, click Exchange. A pop-up will ask you to confirm the exchange. Click Confirm. {% hint style="warning" %} If gMBX is charged as the exchange fee, the amount of gMBX deducted will be displayed in this step. {% endhint %}

{% hint style="danger" %} The exchange may not be processed immediately. In such cases, click View History to check the status of the exchange request. {% endhint %} *** Now, let’s look at the reverse scenario—exchanging gMBX for In-app Currency. The only difference is that no exchange fee is charged in this process. 1. Start from Step 4 from the previous section, instead this time choose gMBX from the "From" dropdown menu.

2. After agreeing with the terms and conditions, click Exchange. In the next pop-up window, enter your MARBLEX trading password.

{% hint style="danger" %} Correctly entering the trading password submits your exchange request. Again, the exchange may not be completed immediately. In such cases, click View History to check the status of the exchange request. {% endhint %} *** ## Accessing your personal information To view your personal information, click the person icon in the top right corner or your account name and then select My Page.

This opens the page where you can view your personal information. Let’s take a look at each tab that is available. *** #### 1. My Assets Here, you can check your balance of gMBX and In-app Currency.

If you do not have a sufficient balance of gMBX, click Swap. This opens up a pop-up window that leads to an interface on MBX Swap that allows you to swap MBXL to gMBX. On the other hand, if you already have In-app Currency, click Exchange and follow the steps from the previous section to exchange them to gMBX. #### 2. Exchange History This page displays the entire record of all exchanges conducted by an account. Click the ▽ icon on the right to expand the details of the exchange so that you can view the TX hash.

If the exchange fails, it will be labeled as “Fail”. If a refund for the exchange fee has been processed, it will display as "Fail (Refund Complete)." Alternatively, if the refund process is still ongoing, it will show as "Fail (Refund in progress)." {% hint style="danger" %} ## WARNING If the status indicates “Fail”, please submit a request to [MARBLEX customer support](https://marblex.zendesk.com/hc/en-us) for follow-up investigation. {% endhint %} #### 3.
