Title: Raspiblitz lncli wallet bumpfee
Post by: nahHoDL on November 03, 2020, 05:26:43 PM
Is it possible to bump the fee of an RBF enabled transaction from the raspiblitz terminal?

After some investigation i found the lncli wallet bumpfee command, but can not seem to get it to work.
Any suggestions?

Take a look at:

https://lightningwiki.net/index.php/Bumping_fee_for_lightning_channel_open

If you have any change from the opening just use CPFP and create a transaction.
It's a bit of a waste of funds but does work.
How low was your fee / how soon do you need it to open.

Hi Dave,

thank you for link to wiki.

I have one question to CPFP from wiki help. In what state will be channel after such successful transaction? Does it have some impact on channel? Somebody on reddit mentioned that "That would logically mean closing a channel and spending the funds in it before it even opens". As I understand it, this doesn`t have an impact on channel but I am not sure if this kind of channel opening wil have some impact on channel closing. Sorry for noob question.

Have a nice day,
Jan

The channel will be open as normal.

Onchain funds ---->TX to open channel
                     \
                       \---Change from above TX --> If from CPFP to spend THIS change with a high enough fee then the 1st transaction will be confirmed because it has to confirm for the this transaction to go through.


Look at it this way. "A" does not have enough of a fee "B" then overpays for their fee and that covers "A"

Not the best but it does work.
