The METAL "Bonus Fund" is a special pool that is filled by users minting METASHIPS (10% of ship cost). 

A % of the Bonus Fund is paid out whenever a ship collects its pending METAL. The % paid out to the ship is determined by its overall [Rarity Level](https://docs.metaships.io/metaships/rarity).

`10000 - (rarityLevel * 100) = % of bonus per collection`
