# How is the APY Backed?

Yieldzard has integrated a solid YCF structure which takes advantage of the trading volume fees in order to back the staking rewards (rebase rewards) when the BNB/YLZ pair supply is worth 2.5% of the total supply.

Scenario: 

When the daily YCF gains are greater than or equal to the entire Holders' Daily ROI, this means that the Swap Threshold can fill the plus-value generated from the Rebase Rewards. 

## YCF >= Daily ROI

If the daily YCF gains are lower than the Holders Daily ROI, a portion of the Treasury is added to fill the difference.

### YCF < Daily ROI -> YCF + Wizard's Chest >= Daily ROI

The result is a self-equalising system that promotes consistent high returns over time to every $YLZ token holder.
