Hello
So there isn’t any kinda web portal that will tell you how much you have made thats going to be later when they do add it to the dashboard, But Brightsilence has a script that you can run that can give you close estimates on how much you will make in a month. You can check it out here Earnings calculator (Update 2020-03-03: v8.1.3 - Now with Audit scores, Vetting progress and DQ indication!).
Its going to be your responsibility to make sure you enter the correct payment address and making sure that the wallet supports transfering Storj tokens out of it.
As for payment there normally sent the first 2 weeks of the month.
