I am looking to have users on my website submit their bitcoin id and be able to accept bitcoin from other bitcoin user as donations.
I am brand new to this. I'm using PHP.
So basically this is what I want to happen.
User A signs up on my website and gets a profile
User A enters their bitcoin address that they want to accept payments to
User B goes to User A's profile and selects to send bitcoin to them
My backend PHP code facilitates the payment from User B to User A and gets notified of a successful transaction.
From what I'm reading there are multiple places someone can have a wallet. Is there a centralized way to send to and from any wallet?
