BEP-721 is a BNB Smart Chain (BSC) token standard that enables the generation of non-fungible tokens (NFTs). It is considered to be an extension of ERC-721, one of the most commonly used NFT standards, and is compatible with the Ethereum Virtual Machine (EVM). ^[1][2]

Overview

BEP-721 tokens enable the tokenization of data ownership, linking it to a unique identifier, and setting it apart from BEP-20 tokens. While BEP-20 allows developers to create multiple identical tokens within a single smart contract, BEP-721 assigns a distinct token ID to each token, making them individually unique. ^[2]

Through these unique IDs, BEP-721 tokens can be used to represent collectible, non-fungible items. Users can trade and transfer these tokens based on their market value, which depends on the token’s rarity or utility. ^[2]

BEP-721 tokens can represent digital and physical art, collectibles, in-game items, physical property, real estate, and lottery tickets. ^[1]

BEP-721 Token Functions

BEP-721 has a list of functions that govern how the token interacts with the BNB Smart Chain. Some of these are standard and are also present in the BEP-20 standard such as:

• name  —  specifies the name by which other contracts will recognize the BEP-721 token
• symbol  —  a concise name for the token, comparable to a ticker symbol
• balanceOf  —  displays the token balance of a given address
• totalSupply  —  shows the overall amount of tokens generated. ^[3]
