After a few weeks of searching for an answer, I decided to ask here.
I want to accept a Bitcoin payment, to a specific wallet, and immediately, when the user approved the payment, to receive an indication that the payment was made.
The problem is, I don't want to wait until it is verified in a block, which takes around 10 minutes, I need the approval in seconds, not minutes.
How can I receive an indication that a Bitcoin transaction was occured to my wallet, in the last seconds?
