What bank does Dash use?

Could you elaborate on the banking arrangements associated with Dash, a popular cryptocurrency? I've often heard about the decentralized nature of cryptocurrencies and their ability to function independently from traditional banking systems. So, does Dash actually have a direct affiliation with a particular bank? Or does it rely solely on blockchain technology and a peer-to-peer network to facilitate transactions? Clarifying this aspect would help me better understand the operational mechanisms behind Dash and how it differs from traditional financial institutions.
