Besides ERC-20, What Is Another Common Token Standard and Its Primary Use?
A common alternative is ERC-721, which is the standard for Non-Fungible Tokens (NFTs) on Ethereum. Unlike ERC-20, ERC-721 tokens are unique and non-interchangeable, each having a distinct ID and metadata.
Its primary use is to prove ownership of unique digital or physical assets, such as art, music, or virtual real estate.
