Using current Git master and want to send all coins from a wallet to another one.
Is there a way to get the final Tx fee sum in one info message?
0.0128772 - 0.001 = 0.0118772 > 0.0113772.
By lowering it more than you needed to you left an input out, making the transaction smaller… thus needing less fee. I don’t see any way of solving that directly.
What I think would help would be options to “take any fee out of the amount being sent” which would remove that problem since the coin selection wouldn’t change, and would do exactly what you wanted for the ‘send all my coins case’. Also, an option to “round sent amount up, up to X btc”, useful when sending to another account of yours, would also tend to reduce fees fairly considerably… but I don’t know how UI for that stuff could be done in a non-confusing way.
Or add a checkbox/combobox, otherwise you’d end up with a lot of text on a button.
In banking software this is generally posed as “who pays the fee”, you or the recipient.
Maybe show a warning when the sender wants to pay the fee but there isn’t enough balance to add the fee.
BTW what if the fee counts towards the amount being sent, but it consumes the entire amount so that the recipient doesn’t receive anything? Can this happen?
