Bitcoin open source wallets that support replace-by-fee (RBF)

[RickDeckard]

I am sorry for this late reply. I am not a Bitcoin Core user. But if you can can provide a guide for it, I can add it somewhere in the OP.

Ever since the release of Bitcoin Core 0.14.0 that the RPC command bumpfee can be used - if one uses bitcoin-cli - in order to increase the fee that was used in a specific transaction (as long as it had Replace by fee enabled). In order to increase the fee by using CLI, per bumpfee documentation[2], you have to respect the following command:

Code:

bumpfee "txid" ( options )

Usually people have trouble with the (options] argument because it is classified as a JSON object ant when constructed incorrectly can output errors such as "Error parsing JSON". An example of a command to bump the fee of an unconfirmed transaction in 40 sat/vB would be:

Code:

bitcoin-cli bumpfee <ARandomTXIDhere> '{"fee_rate":40}'

If you're using the GUI version of Bitcoin Core, things are more user friendly - Ever since Bitcoin Core 0.15.0[3] there is a graphical option for a user to replace the fee of an unconfirmed transaction (assuming it has RBF enabled) by just going into the menu Transactions -> Right-Click on the unconfirmed transaction -> Choose Increase Transaction Fee and then choose the desired sat/vB rate.

RBF has it's downsides for privacy: I always use coin control, and I try to avoid change. So when I used RBF in Bitcoin Core, it took another input, and added it to my transaction. I didn't expect that, and didn't get a warning about it. It's bad for privacy, and lead to a much larger transaction: 2 inputs and 2 outputs instead of 1 input and 1 output.

On Electrum, I can select 'decrease payment' for both bump fee and cancel transaction if I want the additional fee to be deducted from the coins in the transaction (which would be replace by another transaction).

How are you avoiding change?
Only way I know is by sending full amounts, but in situations like that I wish bitcoin was more like monero.

This looks more like a issue with Bitcoin Core wallet than with RBF itself.
I guess you could freeze all other addresses in your wallet to make sure they won't be sent without warning.

Sending the full amount works, or combining multiple payments, or sending the change to an exchange (so it's someone else's problem). Sometimes I send it to an online account where I can use the balance later.
Obviously this doesn't always work, and for small payments I avoid using Bitcoin if possible. I don't like it, but I like Bitcoin too much to waste it on high fees

Yep, it's a Bitcoin Core thing. I now know, so I won't let it happen again.
