Is Paxos a US company?

Could you elaborate on the background and origin of Paxos? I'm particularly interested in whether Paxos is indeed a company based in the United States. Its operations and services seem to span across various financial and cryptocurrency domains, but having a clear understanding of its legal jurisdiction and registration status is crucial. Could you confirm if Paxos is registered as a US entity and if it adheres to the regulatory framework in the US for financial institutions? Your insights would be greatly appreciated.
