How to create ERC-1155 NFTs
Once you have a ERC-1155 NFT smart contract, you can create any number of tokens. Each ERC-1155 token
has a unique tokenId to identify it within the collection and all items of this tokenId share the same
metadata. Many people can own the same token and multiple of each token.
After creating an ERC-1155 NFT, you can start distributing NFTs with the Mint ERC-1155 NFTs API.
Differences with ERC-721 NFTs
While minting ERC-721 NFTs, the unique tokenId associated with each NFT will auto-increment for you, but
minting ERC-1155 NFTs requires an explicit argument for tokenId to indicate which NFT should be minted. For
example, one may define NFT 1 as marking a donor, 2 for participating in last season, and 3 for
being a attendee at the most recent event.
Updating ERC-1155 NFT Metadata
If you need to update the metadata for a particular ERC-1155 token, use the Update NFT Metadata API.
Body
The id of the chain supporting the NFT. This cannot be changed after creation.
The NFT smart contract address to mint with.
Metadata to associate with this NFT, which overrides any defaults set at the collection-level.
Response
Indicates whether the call was successful.
The unique id for the NFT within the collection.
