@anon44204028 is right though. Check their respective websites. Lloyd’s is an insurance business. They are not going to hold anyone’s money. To me it adds to the overall lack of credibility and seriousness that revolut shows.
Incidentally, in my opinion FSCS protection is a much stronger and safer assurance than ringfencing, because FSCS is statutory, while ringfencing depends on the bank (for example it offers no protection at all against rogue employees, failure in procedures, etc.)
