I want to know how many tokenIDs are in an ERC1155 token, how can this be achieved? I want to know how many tokens are in a specific tokenID, how can this be achieved? Are there functions in the specifications that allow for that? Many thanks
You could query the events
TransferBatch and make your calculation for how many tokens are minted. This applies also for your second question. But you always have to look at every implementation separately.
