I have created coins on test network.Now the confusion is,
I have distributed coins to 100 members,who can use those coins to buy digital products(domains) on my platform.Now the confusion is if all domains are listed for sale for $10(100 coins),and multiple domains got sold,how can I identify which user made payment to me.Because all users can see my wallet address.Is there any way to detect that payment came in for which purchased product?
