# AFEE & BonusUSD

### **AFEE**

Aster has a fee discount token called AFEE, which allows users to offset their trading fees on Pro Mode. AFEE is applied automatically and requires no manual activation.

* **1 AFEE = 1 USDT**
* **Total supply:** 100,000 AFEE tokens
* AFEE cannot be used as margin to open positions — you must deposit USDT or another supported collateral asset to trade.
* AFEE can only be used to offset trading fees; it cannot be used to deduct funding rates, liquidation fees, or other costs.
* Users do not need to enable Multi-Asset Mode to use AFEE.

**Note:** When users pay trading fees with AFEE, market makers and referrers will receive AFEE tokens as rebates.

### **BonusUSD**

Aster has a futures bonus token called BonusUSD for users who trade on Aster Pro Mode. BonusUSD is a USD-pegged token that traders can use as collateral to trade crypto futures on Aster Pro Mode.

**Note:** BonusUSD is a futures bonus token and cannot be withdrawn. Multi-Asset Mode must be enabled to use BonusUSD as collateral.

#### **How to Use BonusUSD**
