20.1k sats \ 3 replies \ @xmrk2 18 May 2023 \ on: Help me get on-chain transaction from LND(Umbrel) node with low fee confirmed bitcoin
Should be doable with lncli wallet bumpfee on your umbrel node. It can do both RBF and CPFP. The argument is <tx_you_want_to_bump>:<change output number> of your tx (if doing CPFP), not sure how to do RBF. This assumes there is a change output, you could have sent the whole output to Blixt wallet, then you would need to do CPFP on Blixt side.
Note about RBF: it should not be necessary to have it enabled in your tx - see mempoolfullrbf=1 option of Bitcoin Core. For example my node has this enabled, so would accept replace by fee on any tx. More famous example: Peter Todd's node. There was entire war about this, it surprises me someone hasn't heard of it. :)

I tried this.
umbrel@umbrel:~ $ lncli wallet bumpfee xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx:0
[lncli] rpc error: code = Unknown desc = no fee preference specified
So I added --sat_per_vbyte 200 And I see no tx output
umbrel@umbrel:~ $ lncli wallet bumpfee --sat_per_vbyte 200 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx:0

Both transactions have been confirmed and my channel is being opened in Blixt. Thanks!

I see the transaction in my mempool now. I rebooted my umbrel. My original tx was not showing up so I'm guessing there was an issue with my mempool.
