# Buyback & Burn Policy

$BELT buyback & burning is an automated system based off of yield from beltStrategy contracts ("earn") and trading fees ("swap volume") from Belt Finance's stableswap AMM.

### Yield Buyback

From the earned yield, 12% is used for BELT buyback.

* 8% for burn.
* 4% for BELT Single Staking Pool.

This is calculated as:

* earn \* 0.12 = belt buyback amount

This is done for each earn() transaction for each beltStrategy contract. This happens **every 12**

**hours**.

### Trading fee Buyback

50% of trading fees from swap volume are used to buyback and burn BELT.

This is calculated as:

* swap volume transaction fee \* 0.5 = BELT buyback amount

The buyback() is executed **one time a day** from the accumulated amount in the swap contract:
