- The most common standard for creating tokens on the Ethereum blockchain is the ERC-20 stands for Ethereum Request for Comment 20 and refers to a technical standard used for smart contracts on the Ethereum blockchain for implementing tokens. It is the most common standard for creating and issuing tokens on the Ethereum network. Key Features: • Standardized Functions: ERC-20 defines a set of standard functions that a token contract on Ethereum must implement.... More standard, while NFTs often use the ERC-721 stands for Ethereum Request for Comment 721 and represents 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.
