You don’t have enough PRV to pay the fee for this transaction.
Can it be done like how adding and withdrawing from the staking area is done?
There is a “max” button that you hit, that calculates the fee, then you hit max again and it deducts the fee and truly takes the max out. Can that be done for adding and withdrawing liquidity and when trading (cause I always have a little left over when I would like the full amount to be withdrawn with no left overs tabulated by the program).
