Yeah, I was suspecting that user deposits would still be accessible since EU has some pretty stringent regulations for requiring the use of a partner bank for custody, among other things (It's the reason why most forex sites and e-wallets have a disclaimer that says their services are offered by "Bank of ABC Natural Name ltd").
Yes, you are right. Our former banking partner Solaris is obliged to provide access to the funds in the bank account for at least three years. However, users have to actively request there funds back, in case they have forgotten to withdraw their funds before the announced closure.
The funds can be requested back by getting in touch with their customer support:
