ERC1155 is a semi-fungible token standard (SFT) that allows a single smart contract to represent multiple fungible and non-fungible tokens, serving as a multi-asset token standard. Despite being defined by the Enjin team, it has not been extensively explored. As a game item effect NFT, it has the following advantages:

• Supports batch transfer and batch issuance, reducing the time and cost required for transactions

• Supports multiple assets within a single contract, enabling more efficient management and operation of multiple items

• Supports atomic transactions, ensuring the simultaneous transfer or exchange of multiple assets and avoiding the risk of unmatched transactions

• Supports metadata and URI, providing detailed information and descriptions about assets, increasing scalability and interoperability

• Enables different effects of items to be implemented within a single contract, increasing game diversity and fun
