### Ubit's Fiat Gateway: A Behind-the-Scenes Look

Ubit's upcoming fiat payment gateway aims to simplify user experience by bridging the gap between traditional finance and the Ubit ecosystem. We have a fully automated workflow for the same.

**Step 1: User initiates a purchase**

* A user on the Ubit platform chooses to purchase UBIT tokens using their preferred fiat currency (e.g., USD, EUR).
* The user selects a familiar payment method like Stripe for a smooth and secure checkout experience.

**Step 2: Fiat payment processing**

* Upon successful payment via Stripe, the Ubit system receives a confirmation signal.

**Step 3: Automated workflow triggers**

* This signal triggers an automated workflow within the Ubit platform.

**Accessing the USDT vault**&#x20;

* The system  accesses a pre-funded vault containing USDT (Tether, a stablecoin pegged to the US dollar).

&#x20;**Generating a deposit address on Coinstore**

* A deposit address is generated for usdt on coinstore and USDT is submitted to the coinstore

&#x20;**Placing an order for UBIT-USDT pair**

* An automated order is placed within the coinstore to buy UBIT tokens using the converted USDT.

**Withdrawing UBIT to user's wallet**

* Once the UBIT purchase is complete, the system automatically transfers the acquired UBIT tokens to the user's designated wallet address on the Ubit platform.
