Smart NFT 1155 – Multi-token standard addon

ERC-1155 standard interface for contracts that manage multiple token types. A single deployed contract may include any combination of fungible tokens, non-fungible tokens, or other configurations (e.g. semi-fungible tokens).

Initially, SmartNFT had built-in ERC-721 contract standards but currently, the most popular standard for minting is 1155 in which multiple editions of an NFT can be published.

This standard outlines a smart contract interface that can represent any number of fungible and non-fungible token types. Existing standards such as ERC-20 require the deployment of separate contracts per token type. The ERC-721 standard’s token ID is a single non-fungible index and the group of these non-fungibles is deployed as a single contract with settings for the entire collection. In contrast, the ERC-1155 Multi Token Standard allows for each token ID to represent a new configurable token type, which may have its own metadata, supply and other attributes.
