TY Crypto Capital.  This brings me back to my original question, which banks are you working with?
For a real-world example:
I live in US, NY, NYC, which bank would I be dealing with?  I'd like to contact that bank and verify your involvement with it.
TY again.

Re. "no need to trust or provide your information to the trading software provider, they are a software company, not a financial one":

An exchange operator is an exchange operator, a software provider is a software provider.  If the software provider happens to also be running the exchange, he becomes both.  I'm afraid you've been mislead by your legal counsel.
