Hoping to get some information from the community, as I've been searching for hours.
We own a platform that processes payments for our vendor/customers in stripe and paypal. Recently, we started to look into processing bitcoin/alt's too - but there seems to be limited information available around the topic.
Using APIs that are available, we can create and receive payments without a problem. But that will put us at the mercy of those platforms, creating a 3rd party nightmare.
What would be the minimal requirements or how would one create a payment solution without using all these other integrations.
