Rarity

What is Rarity?

Rarity measures how scarce an individual NFT is compared to others in the same collection. It is determined by trait frequency, with rarer traits commanding higher prices on the secondary market.

How does Rarity work?

1. A generative collection defines traits with varying probability weights.
2. An algorithm randomly assigns traits to each token, creating unique combinations.
3. After mint, rarity tools calculate how often each trait appears across the collection.
4. Each token receives a total rarity score and rank based on its trait combination.

Why does Rarity matter?

Rarity is the primary driver of NFT value, giving collectors a clear hierarchy for pricing. It creates a game within a game where acquiring the rarest items signals status and maximizes resale potential.

Key features of Rarity

• Mathematically calculated from on-chain trait metadata
• Objective ranking system that influences floor prices
• Foundation for reveal events and post-mint trading activity
• Verified by third-party tools like Rarity Sniper

Examples of Rarity

In Bored Ape Yacht Club, an ape with "Gold Fur" can sell for 10 times the floor price. CryptoPunks with the "Alien" trait number only 9 out of 10000, making them among the most valuable NFTs ever sold.
