NFTs: key words

A non-fungible token: a token that is individually unique, unlike ETH or USDC, where every unit is the same. Source

An Ethereum standard for NFTs. Each token is tracked separately, and each token ID has exactly one owner, so a wallet holds none or one of it. Source

A multi-token standard: one contract can hold fungible tokens, NFTs, or a mix. Source

The number that identifies one NFT inside its contract. With the contract address, it picks out exactly one NFT. Source

Details about an NFT, such as its name, a description and a link to its image, usually kept in a JSON file. Source

An ERC-721 function that gives the address of a token's metadata. ERC-721 lets this address change. Source

Keeping an NFT's picture somewhere other than the blockchain, with the token pointing to it. Most NFT works are stored this way. Source

A content identifier in IPFS: an address made from the content itself, so any change to the file gives a new CID. Source

To create a new NFT by publishing a new token to a blockchain. Source

A website for buying and selling NFTs, which usually takes a percentage of each sale. Source

A share of each resale paid to an NFT's creator. Under ERC-2981, paying it is voluntary for marketplaces. Source

An item's history, traced through who has owned it, held it and used it. Source
