Our rarity ranks are generated by a standardized scoring algorithm based purely on the traits in the NFTs metadata. We also take in to account the trait count, which is usually what collections on rarity.tools do as well. SuperSea is not an official authority for the rarity of NFTs. Please understand that our reported rank could be inaccurate for a number of reasons:

• There's a bug in our code.
• The collection has been ranked before all metadata was revealed.
• The collection had its metadata updated after we ranked it.
• The community does not consider a standardized scoring algorithm based on combined trait rarity to be an accurate representation of what is a sought-after item in the given collection.

Never make a purchasing decision based on our reported rank alone, always do your own due diligence. We recommend you to use the score breakdown, accessed by clicking the rank text, to judge if we've produced a reasonable rank based on the traits.
