How to mint ERC-1155 NFTs

Once you have created ERC-1155 tokens, you can mint any number of a token to any address. You can check which tokens you have already created for your ERC-1155 collection with the Query ERC-1155 NFTs API. If you have not yet created any tokens, first do so with the Create 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.
