What bank does Binance work with?

I'm quite curious about the banking relationships of Binance. As a leading cryptocurrency exchange, I'm sure they must have established some sort of partnership with traditional banks for deposit, withdrawal, and other financial transactions. Could you please enlighten me on which banks Binance works with? Are these relationships exclusive or do they collaborate with multiple banks? Additionally, how does Binance ensure the security and efficiency of these transactions, given the unique challenges associated with cryptocurrency and traditional finance? Thank you for your time and insights.
