From what I gather this is the Tesla of banks (comparing new kid on the block to the old guard – Tesla vs GM): meaning it's a modern bank with systems that run on something newer than COBOL with an open API. It's extremely cool and looks like it may set the standard of what banks must be in the future to compete with newer generations coming into the market.
The most direct connection possible to the federal reserve with as little overhead as possible, accessible entirely over battle tested modern network API technology
EDIT: add " coming into the market" to the end
