# Rocket Fuel NFTs

### Contract

0xF73Bf3815b7C2D34f406B58ab9749433f7c79B09

### Overview

There are four types of Celestial Finance Rocket Fuel NFTs.  Holding any of these NFTs will grant a bonus to farm yields for the holder.  The NFTs function as a multiplier of the base rate of Stars emission.  The four NFTs stack bonuses with each other, though only one of each type will be counted for bonus.  The four NFTs stack for a total bonus of +250% (25+50+75+100).  The bonuses are additive with each other, not stacking multipliers.

If the base Stars daily yield is 1.4%, the first NFT will raise this to:

```
1.4% * (1 + 0.25) = 1.75% daily 
```

If the base Stars daily yield is 1.4%, the first two NFTs will raise this to:

```
1.4% * (1 + 0.25 + 0.5) = 2.45% daily
```
