- Rarity rank orders a collection rarest→commonest; rank #1 is the rarest.
- Rarity score is the underlying number; rank is derived from it.
- A rarity filter scopes a collection to a band (top 1%, ranks 1–500, …).
- Rarity bidding = rarity filter + a trait bid on the traits that drive the band.
- Different providers can rank the same NFT differently — confirm which ranking a number uses.
What is NFT rarity?
Within a generative collection, every NFT is a mix of traits, and some trait values are far rarer than others. Rarity captures how uncommon a given NFT's full combination is. It's expressed two ways: a rarity score (a number — higher is rarer) and a rarity rank (the NFT's position when the whole collection is sorted by score, so rank #1 is the single rarest piece).
The market prices this in: the rarest NFTs — the "grails" — trade well above the collection floor. Treating a collection as one flat floor price ignores that premium entirely, which is exactly the gap rarity bidding exploits.

How a rarity filter works
A rarity filter narrows a collection to a rarity band so you only look at — and only bid on — the pieces you care about. Filter to the top 1% and the 9,900 common NFTs disappear from view; you're left with the ~100 rarest, where the real price dispersion (and opportunity) lives. It's the difference between "buy any cheap NFT" and "buy underpriced rare NFTs."
Turning rarity into an automated bid
You can't place a single on-chain offer that says "buy anything ranked under #500" directly — but you can achieve it through traits. Rarity is driven by specific trait values, so the practical recipe is:
- Apply a rarity filter to find the band you want.
- Identify the trait(s) that consistently push NFTs into that band.
- Place a trait bid on those traits.
Now your automated offer only fills NFTs carrying the rarity-driving traits — effectively a rarity-scoped bid that the bot keeps competitive for you.

| Manual | Chadbot | |
|---|---|---|
| Finding rares | Scroll listings, cross-check a rarity site | Filter the band, bid the rarity-driving trait |
| Buying floor by mistake | Risk if you place a blanket collection bid | Never — the trait bid only fills the rare subset |
| Catching the rare listing | You have to be watching when it lists | Standing bid fills automatically the instant it's sold into |
Bid by rarity in five steps
- Open a collection in discovery.
- Apply a rarity filter to the band you want (e.g. top 1%).
- Find the rarity-driving traits in that band.
- Place a trait bid on those traits with a sensible max.
- Fund escrow & start from the bots page.
FAQ
What is NFT rarity?
Rarity measures how uncommon an NFT's combination of traits is within its collection. It's usually expressed as a rank (1 = rarest) or a rarity score (higher = rarer). Rarer NFTs typically command a premium over the collection floor.
What is the difference between rarity rank and rarity score?
Rarity score is a number computed from how rare each trait is; rarity rank orders the whole collection by that score (rank #1 is the single rarest). Rank is easier to filter on — 'top 100' or 'top 1%' — while score is the underlying value the rank is derived from.
What is a rarity filter?
A rarity filter restricts your view or your bot to NFTs within a rarity range — for example only ranks 1–500, or only the top 5%. It lets you find and bid on the rarer subset of a collection instead of the whole thing.
How do I bid by rarity?
Use a rarity filter to scope the collection to the ranks you want, then place trait or collection bids on that subset. On Chadbot you can target the specific traits that drive rarity, so your offer only fills NFTs in the rarity band you care about.
Are rarity ranks the same on every marketplace?
Not always — different providers (e.g. rarity methodologies used by Tensor vs Magic Eden vs HowRare) can rank the same NFT slightly differently because they weight traits differently. Always check which ranking a number refers to before bidding on it.

Rarity bidding is trait bidding with intent — read the trait bidding guide for the mechanics, run a market-making pool on a rare subset, and list cross-marketplace when you flip a grail.
