I was checking your site and stumbled upon the pricing page. Can you explain the difference between Address Watcher Users and Merchants?
Merchants have payment callback url to receive payment notifications. Address Watcher users don't
Another thing I cannot figure out is, if the payment goes directly to merchant's wallet, how do you get your fees?
Good question ! Each user has a prepaid credit balance in BTC. Fee is deducted from that. You can deposit BTC into your credit balance when it is running low. Can check this on
