Uniq.cx

The world’s largest digital marketplace for crypto collectibles and non-fungible tokens (NFTs), including ERC721 and ERC1155 assets. Buy, sell, and discover exclusive digital assets like Axies, ENS names, CryptoKitties, Decentraland, and more. Building brand new economies powered by true digital ownership. OpenSea is the first and largest marketplace for user-owned digital goods, which include collectibles, gaming items, domain names, digital art, and other assets backed by a blockchain. At OpenSea, we're excited about a brand new type of digital good often referred to as a non-fungible token, or NFT. NFTs have exciting new properties: they’re unique, provably scarce, liquid, and usable across multiple applications. Just like physical goods, you can do whatever you want with them! You could throw them in the trash, gift them to a friend across the world, or go sell them on an open marketplace. But unlike physical goods, they're armed with all the programmability of digital assets.

rarity.tools aims to provide an easy to understand and sensible ranking of the rarity of individual collectible NFTs and can be used to easily answer the question of how rare any NFT is within their collection. With this info NFT collectors can more easily value and compare relative value of individual NFTs against each other. The big picture is, each trait of an individual NFT is given a Rarity Score and then the Rarity Score for all traits of that NFT are added up to become the NFTs overall Rarity Score. The CryptoPunks community for example gives a lot of importance to the ‘attribute count’ of each CryptoPunk, which is why the only CryptoPunk with 7 attributes is ranked as the rarest one. On the other hand other communities don’t really care about attribute count. The Waifusion community gives importance to clothing and style matches.
