What is ERC721? ERC721 is a token standard on Ethereum used to create non-fungible tokens, or NFTs. Each ERC721 token is unique and can represent ownership of a specific digital or physical item.
ERC721 Explained ERC721 is a rulebook for making unique tokens on Ethereum.
Some tokens are like dollar bills: one is the same as another. ERC721 tokens are different because each one has its own identity.
Think of it like a collectible trading card. Even if two cards are from the same game, each card can have different traits, history, or value.
That is why ERC721 is commonly used for NFTs, digital art, gaming items, memberships, tickets, and other assets where each item needs to be one of a kind.
