Frequently Asked Questions
How is NFT rarity calculated?
Rarity is calculated by dividing 1 by the percentage of NFTs that have each trait. Traits that appear less frequently contribute more to the overall rarity score.
What makes an NFT rare?
An NFT is considered rare when it has traits that appear in a small percentage of the collection. The fewer NFTs that share a trait, the rarer that trait is.
What do the rarity tiers mean?
Common (low score), Uncommon, Rare, Epic, and Legendary (highest score). These tiers are based on the average rarity score across all traits.
Does rarity affect NFT value?
Rarity is one factor that can influence NFT value, but it is not the only one. Art quality, artist reputation, utility, and market demand also play significant roles.
How do I find trait occurrence data?
Most NFT marketplaces like OpenSea display trait rarity percentages. You can also find this data on rarity tools like Rarity.tools or HowRare.is.
