What network does SwissBorg use?

I'm curious to understand the underlying technology that SwissBorg relies on. Could you elaborate on what blockchain network SwissBorg utilizes? Given the numerous options in the cryptocurrency landscape, I'm particularly interested in knowing if they've chosen a mainstream platform like Ethereum or Bitcoin, or perhaps they've ventured into more niche networks. The choice of network could have significant implications on transaction speed, scalability, and overall user experience. Could you provide some insight into this aspect of SwissBorg's operations?
