Does Bank of America work with Kraken?

Excuse me, I was wondering if you could clarify something for me. I've been doing some research on cryptocurrency and I came across Kraken as a popular exchange platform. I'm curious to know if Bank of America, a major financial institution, has any kind of partnership or working relationship with Kraken. Is there any information you can provide on whether or not these two entities collaborate in any way? Thank you for your time and assistance.
