I wrote this payment gateway for myself. :-) A versatile payment gateway. All kinds of currency are in it. For example, we can add PayPal, Visa Card, Perfect Money, Web Money and so on. Then any customer who would like can come to my site and have a payment gateway for their site. For example, get the PayPal port with one click. Or, without having to change the programming of your site, just switch to another payroll in just a few seconds, in the user panel I gave it.
I use this gateway for all of my projects and/or my clients (if they like it) to be safe and comfortable.
I wrote the core of this payment gateway so that we could add it to any gateway. Even cryptocurrencies can be added to this gateway. Any payment gateway from any country.
