Umbrel unable to spend ALL onchain BTC \ stacker news ~bitcoin

12 sats \ 5 comments \ @2bithits 25 Apr 2023 bitcoin

Anyone know why you cannot spend all remaining sats in the onchain wallet?

I tried sending the remaining change out into another wallet. It still kept a few thousand sats in there. Not sure why.

Also, I like being able to spend the whole UTXO to open up a channel. Haven't been able to do so with the apps on umbrel like RTL, thunderhub etc. I'm sure you can do it in the terminal so I'd appreciate some links as to how.

Thanks

If you are using the LND implementation, there's an anchor reserve for the channels you have open. Here you can read more about anchor reserve https://lightning.engineering/posts/2021-01-28-lnd-v0.12/ It is like an UTXO with max 100k sats that must be kept. So if you have open channels, that must be.

Is not about Umbrel. Umbrel is just a dumb web UI interface, is not the node itself. Is about the LND code.

So I suggest to always keep only one UTXO with 100k sats in it, as a reserve. Then you will be able to spend a whole UTXO to open channels. I know, is kinda stupid, but until Eltoo will be implemented, we have long walk to go...

Maybe this guide could help you more https://darthcoin.substack.com/p/how-to-consolidate-utxos-to-open

Thanks

It didn't say anything about the 100k sats maximum. Is it the same if you have 2 channels or 200 channels?

Is usually 10k sats/channel, but no more than 100k in total, if you keep it in one UTXO always. Re-organize your UTXOs and always keep one UTXO with 100k. Never use that UTXO for opening channels. And all will be just fine.

Have you tried to link it to Zeus Wallet and spend it from there? You can open channels from there too.

Yes, I also had a problem spending a different UTXO that I wanted
