Hmmm,

local transfer I still have

claim, I did get the toast but I had more than 0.05. or maybe this is already calculated how many eras I need to claim and how much I would need?

Can we have the same messages of lacking the balance to pay the fee?

So we are checking if user balance is greater than 0.05. I believe the main reason is because we want user to have some tokens in the future to be able to pay transaction fees.
What we are not checking here is how much tokens will remain in the user wallet after transaction (e.g. balance transfer).
