Connecting to MBX Station

Welcome to the main page of MBX Station. The first thing to do is get connected.

  1. Click Connect in the top right corner and select your login method.

A new feature that was introduced with the Immutable zkEVM migration is the ability to switch between MARBLEX Wallet and Immutable Passport.

With a single click, users can switch between accounts, though a login is required for each option.

From the main page, there will be an array of games listed under Project List.

Choose your favorite game, preferably one in which you already have in-app items. This will bring up the Info page for the game.

  1. Click Link Project and select your login method

Only one wallet can be used to link with one game account. Attempting to connect multiple accounts will result in an error message.

  1. After selecting an account to link with the game, a pop-up will open. Click Agree.

Congratulations! You have successfully linked your account with the game.

Exchanging in-app items and gMBX

Now that we’re connected to the game, let’s take a look at how to exchange in-app items with gMBX.

  1. From the main page of MBX Station, hover your mouse over a game and click Go to Exchange.

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

  1. Choose the direction of the exchange. If you want to exchange in-app items for gMBX, select an in-app item from the "From" dropdown menu.

In the image above, the World Fighting Championship Key is the in-app item.

  1. Enter the amount you want to exchange, and the output value (gMBX) will be automatically calculated based on the current exchange rate.

The exchange fee may be charged in in-app items or gMBX and is calculated using the AMM method.

In-app items are items that 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.

  1. Next, click the Terms of Service button. Read through the Terms & Conditions and click Agree.

  1. After agreeing to the terms and conditions, click Exchange. A pop-up will ask you to confirm the exchange. Click Confirm.

If gMBX is charged as the exchange fee, the amount of gMBX deducted will be displayed in this step.

The exchange may not be processed immediately. In such cases, click View History to check the status of the exchange request.

Now, let’s look at the reverse scenario—exchanging gMBX for in-app items. 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.

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

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.

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.
