No, you need to provide the bank account number first, then order an exchange and send us a transfer.
The system assigns each account an individual code which also appears in the title of the transfer. Therefore, the account has to be provided at the very beginning, at the stage of placing the exchange order.
If you send us a transfer first, and the destination account is not added, you will be able to return the funds to your account or send them to another account that you had previously added to your profile.
