Here's the one i try to transfer all the balance to myself by using tonweb sdk (https://github.com/toncenter/tonweb), but the transaction broadcast and failed.

I think it is the reason that i did not minus the transaction fee and cause the insufficient balance to finish the transaction . But the estimateFee () return a dynamic value , if i try to minus the fee before i broadcast the transaction , will it causes the few balance left or broadcast fail by lack of tiny transaction fee ?

Tonkeeper do this perfectly and i wonder how they implement this function.
