BEP-721 is the standard for non-fungible tokens (NFTs) on the Binance Smart Chain, similar to ERC-721 on Ethereum. It's what makes each NFT unique and one-of-a-kind, like a snowflake or a fingerprint.
Example
"If you want to create NFTs on the Binance Smart Chain, you need to use the BEP-721 standard."
"BEP-721 NFTs can represent all kinds of digital assets, from art and collectibles to in-game items and virtual real estate."
