It's not really hard. You setup corporate accounts on all major banks, and setup a fancy UI that let's people "email" each other money, when you're just shuffling money around in the background for them, in an automated way. It's just a middleman so you don't actually have to give others your bank info because they store it for you, and vice versa. Sorta like escrow. Get big enough, and you don't even have to move much money around, as long as it stays in the ecosystem, going back and forth between PayPal accounts. You only need to have enough cash to cover what people withdraw, like how actual banks work. Nothing about what they do is special, anyone can do it— they just had amazing marketing and it was the only payment processor accepted on eBay during its glory days. GabPay probably does exactly the same thing.

If you can publicly not-hate-white-people and still participate in the financial system, then I stand corrected.
