ERC-1155 is an NFT standard that creates multiple edition NFTs. That means it creates one token on the marketplace. They're like a series of art prints: The artwork is all the same, but you can own multiple editions (and you probably own the same artwork as many others).
An ERC-1155 might only have one edition or could have an edition of hundreds of thousands. The number is always set by the creator.
An ERC-1155 contract is the smart contract that powers these NFTs. To save you from having to learn smart contract development, we have a contract you can use to mint your own ERC-1155 tokens. Here's how it works:
Creating an ERC-1155 NFT on Rarible:
1. Click on "Multiple" when creating an NFT.
2. Complete all of the relevant fields. Once you reach the "Choose collection" section, either choose to mint your NFT on Rarible's collection or create your own ERC-1155 collection. Having your own collection costs more gas fees, but also makes your artwork easier to find. Once you have selected either Rarible's collection or creating your own ERC-1155 collection, click on "Create item."
