# Gas Refueling

## Gas Refueling – Interface Documentation

**Gas Refueling** allows your organization to top up blockchain-native gas (e.g., ETH, TRX, MATIC) used for sweeping deposit funds from customer addresses into your central wallet.

This gas is stored in a dedicated **"Station Wallet"**, separate from any user-facing deposit address — ensuring you maintain uninterrupted operations without worrying about gas availability on each incoming address.

### When Do You Need to Refuel?

You’ll need to refuel gas when:

* You see gas balances running low on any supported chain
* You anticipate high transaction volume requiring many sweep operations
* You want to proactively ensure sweeping never fails due to gas shortages

### How to Add Gas in the Terminal

1. On the main Terminal dashboard, locate the **“Gas Balance”** panel.

**Steps:**

1. Select the **Blockchain** you'd like to fund.
2. A **dedicated deposit address** will be generated along with a **QR code**.
3. Send the required gas (e.g., TRX, ETH) to the address shown.
4. The station wallet will be updated once the transaction is confirmed.
