Is dYdX allowed in the UK?

Could you please clarify for me, is the cryptocurrency exchange platform dYdX permitted for operation within the United Kingdom? I've been considering utilizing its services but am unsure about its legality in this jurisdiction. Given the evolving nature of cryptocurrency regulations globally, it's important for me to ensure I'm compliant with any relevant laws. Would you happen to know if dYdX holds the necessary licenses or registrations to operate legally in the UK? Additionally, are there any specific restrictions or guidelines that users in the UK should be aware of when utilizing dYdX? Thank you for your assistance in clarifying this matter.
