#NFT is technology. To be precise an ETH smart contract standart.
Token, but non fungible.


The ERC-721 introduces a standard for NFT, in other words, this type of Token is unique and can have different value than another Token from the same Smart Contract, maybe due to its age, rarity or even something else like its visual. Wait, visual?

Yes! All NFTs have a uint256 variable called tokenId, so for any ERC-721 Contract, the pair contract address, uint256 tokenId must be globally unique. That said, a dApp can have a "converter" that uses the tokenId as input and outputs an image of something cool, like zombies, weapons, skills or amazing kitties!


Why some NFTs sells for millions and others not?

Even from the same collection
