We are aware of the wish to be able to withdraw DOT outside the Safello wallet and we are of course working to have this functionality in place over time. As we continuously improve the functionality of our cryptocurrency wallet, we place great emphasis on sustainable and secure solutions, which means that it can take time before this functionality is implemented in full.
Needless to say, we will of course make an announcement as soon as we have a solution in place and hope for your understanding and patience until then.
