When you close a LN channel, some of the coin belongs to you, and some belongs to the other party to the channel. If the other node does not want to potentially wait days to access their coin, it will not sign a cooperating closing tx with a low fee. If the other node is not cooperating and you want to unilaterally close the channel, you must use a previously signed tx, including whatever fee rate was set.
I'd like to see older channel states but Eclair doesn't show them. I guess I'll have to dig into the backups made on Google Drive for those?As a proof of concept, it would be interesting to see if I could actually use an older transaction to steal funds (and if I succeed give them back to the node, but that's not the point here). I currently have a channel (opened by me) with only just over 3000 satoshi on my side. If I'm the only one paying for fees, I don't expect any of this money back in my wallet. But even all of it is used as fee, it won't be a high fee. So: what if I wait until fees go up, then close the channel, which won't confirm, and after the right amount of time, I broadcast an older state (which at the time might have been signed with a higher fee)?
It's still a mystery to me how the older signed transactions would work, given the fact they can't be broadcasted instantly but only a certain amount of time after trying to close the channel.
I understand what you said, but that wasn't the case. The other party of the channel wasn't in hurry, it was loycev.
It really was a lack of transparency and fee control. Eclair wallet is a good wallet for testing, but it has many problems, and fee customization is one of them.
You're mistaken though It really was a lack of transparency and fee control. Eclair wallet is a good wallet for testing, but it has many problems, and fee customization is one of them.
You made a LN transaction with me, but you didn't have a direct LN channel to me. I don't even run a node! I was using a light wallet, just like you, and you opened/closed the channel with another node.Quote
[There was no way to customize the fees and choose how many sat/byte I would like to pay.
It might help to wait until fees are low for a while, then close the channel. I would expect a lower fee that way (but haven't tested it yet).
