ERC stands for "Ethereum Request for Comments”. ERC-1155 is a multitoken standard that allows multiple tokens of different types to be created and controlled in the same contract. The ERC-1155 supports both fungible and non-fungible tokens, which constitutes the biggest difference to the ERC-721 standard. In other words, the ERC-1155 can create one or more fungible tokens and non-fungible tokens within the same contract. Also, the ERC-1155 standard enables large-scale transfers of the tokens contained in a smart contract. Furthermore, ERC-1155 tokens are able to recognize the interface of a token.
