# ORB NFTs

ORB NFTs are created using the ERC 404 dual token standard

Token supply- 7777 $ORB

Holding one full $ORB token auto-mints an ORB NFT from a pre-minted pool of 7777 ORB NFTs

These NFTs have 4 levels of rarity

* `Common (7000)`
* `Uncommon (700)`
* `Rare (70)` 
* `Legendary (7)`

The standard deviation (σ) between trait scores reduces as we go from common to legendary, which makes the rarer ones more balanced and less exploitable for gameplay.
