ERC-1155 is the multi-token standard that allows a single contract to manage both fungible and non-fungible tokens simultaneously. Unlike ERC-721 where every token is unique, ERC-1155 supports editions — meaning multiple copies of the same asset can exist, each with the same metadata but a distinct serial number. This makes it ideal for limited-edition collectibles (e.g. 100 prints of an artwork), gaming items (where many players might own the same sword or armor), trading cards, and any scenario where semi-fungibility is needed. ERC-1155 is significantly more gas-efficient than ERC-721 for batch operations, which is why it's the preferred standard for gaming and collectibles platforms. ERC-1155 Standard→
