You can transfer funds to and from your RoarMoney account using any of your linked bank accounts or your MoneyLion investment account. That means any account you have linked in your MoneyLion Wallet may be used to add or receive funds.
If you have a MoneyLion Checking account, you may only use one linked bank account to make transfers to and from your MoneyLion Checking account. This is due to limitations at the partner bank on that account. The RoarMoney account does not have this limitation.
