| ERC-721 What is ERC-721? ERC-721 is a free, open standard that describes how to build non-fungible or unique tokens on the Ethereum blockchain. While most tokens are fungible (every token is the same as every other token), ERC-721 tokens are all unique. Think of them like rare, one-of-a-kind collectables. ERC-20: A CLASS OF IDENTICAL TOKENS ERC-721: A CLASS OF UNIQUE TOKENS The Standard ERC-721 defines a minimum interface a smart contract must implement to allow unique tokens to be managed, owned, and traded. It does not mandate a standard for token metadata or restrict adding supplemental functions. pragma solidity ^0.4.20; /// @title ERC-721 Non-Fungible Token Standard /// @dev See https://github.com/ethereum/EIPs/blob/master/EIPS/eip-721.md /// Note: the ERC-165 identifier for this interface is 0x80ac58cd interface ERC721 /* is ERC165 */ { /// @dev This emits when ownership of any NFT changes by any mechanism. /// This event emits when NFTs are created (`from` == 0) and destroyed |
