Review:
Token Standards (e.g., Erc 20, Erc 721)
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Token standards such as ERC-20 and ERC-721 are protocols defining how tokens behave within blockchain ecosystems, primarily on Ethereum. ERC-20 enables the creation of fungible tokens that are interchangeable and uniform, widely used for cryptocurrencies and utility tokens. ERC-721 establishes a standard for non-fungible tokens (NFTs), which are unique digital assets representing ownership of art, collectibles, or other one-of-a-kind items. These standards facilitate interoperability, security, and consistency across various decentralized applications and marketplaces.
