• LOE for implementation
• Can we generalize to allow the connection of multiple wallets when some are active / inactive?
• most basic option would just be adding a view only addy that couldn't be used (and maybe safest)
• ideal state would be to allow any number of view only wallets to be entered into the new account management flow that are view only.
• any portfolio view will be consolidated with all connect wallets (view only and fully functional)
• time box to ~8 hours

No real estimates as of now, as this brings more product issues and questions to the table than it solves.
