Is the project open source? Can the user check the code?
If it is not, you need trust, and I do not think that anyone will use such a service unless it is possible to link directly between the program and your bank account.
Can you integrate with btcpayserver.org in 60 minutes? with just a 2 line iframe?
The project was not coded with opensource code. It is code proprietary to us.
The code contains many security features and controls. The users cannot check the code - because doing this would open us up to security risks.
We do not want to be dealing with bank payments in this service. The whole idea of it is to deal only in Bitcoin payments, thus removing all of the friction and risk of bank payments.
