Question: If you are selling a set of items and each item can only be sold/bought once. How would it be possible to take an ADA payment and stop multiple people from buying the same product more than once?
You can setup a payment address for each item/product, but there will be a time, between one person purchasing and another purchasing. Where a second or n number of purchases could be made before the product gets marked as sold.
Do you refund anyone who purchased after the initial purchase… yuk!
Any assistance would be great!
