No single regulator "owns" financial technology in the United States. A lending app may answer to the CFPB for its disclosures, to FinCEN for its anti-money-laundering program, to fifty state regulators for its licenses, and to its partner bank's federal supervisor for everything the bank touches. The result is a compliance map that looks less like a rulebook and more like a patchwork quilt.
These guides trace that patchwork: who regulates what, when a product triggers state money-transmitter licensing, what bank partnerships really require after the interagency guidance on third-party risk, and how UDAAP enforcement reaches marketing language that engineers never thought of as "legal copy."
