ERC refers to the Ethereum Request for Comments protocol, which is used to propose and discuss changes and improvements to the Ethereum network. ERC tokens are tokens that conform to these standards and are compatible with the Ethereum blockchain.
There are several types of ERC tokens, including ERC-20, ERC-721, ERC-1155, and ERC-777, among others. ERC-20 tokens are the most common type and are used for creating fungible tokens, such as cryptocurrencies and utility tokens. ERC-721 tokens are used for creating non-fungible tokens (NFTs), which are unique and indivisible assets. ERC-1155 tokens are used for creating both fungible and non-fungible tokens in a single smart contract, and ERC-777 tokens are used for creating more advanced fungible tokens with additional features.
The preference for a particular ERC token depends on the specific use case and requirements of the project. For example, if a project wants to create a cryptocurrency or utility token, then ERC-20 would be the most suitable choice. If the project requires unique and indivisible assets, such as collectibles or game items, then ERC-721 would be a better choice. Similarly, if a project requires both fungible and non-fungible tokens, then ERC-1155 would be a better choice.
