What is an ERC-1155?

ERC-1155 is an Ethereum token standard designed to handle multiple types of tokens within a single contract. Unlike earlier standards such as ERC-20 (for fungible tokens) and ERC-721 (for non-fungible tokens), ERC-1155 allows for both fungible and non-fungible tokens to coexist within a single contract, reducing the complexity and gas costs associated with managing multiple token types. This flexibility has made it popular for use in gaming and NFT ecosystems, where a single contract may manage various types of in-game assets and collectibles.
