Opening an LN channel with funds from another wallet

3138 sats \ 9 comments \ @hades 12 May 2023 bitcoin

Issue: Open a channel on an LN node by funding it from from someone else's wallet. Let's say an individual were willing to do this transaction for me from their wallet in exchange for cash. I hand them cash and they would fund a channel the equivalent value between me and someone else. How could I do this without first sending the funds to open the channel from their wallet to the one on my node?

-not opening a channel to each other -no transfers before the open

PSBTs is the answer. You open new channel with your LN node, node gives destination address and amount, other party builds transaction that sends sats to that address and gives you PSBT. Very important that other party does not broadcast transaction to the network, just give you PSBT. Then you provide that PSBT to your node.

For CLN see fundchannel_start and fundchannel_complete.

For LND see Opening a channel by using a PSBT.

This is powerful. Thank you. I'll need to practice a bit. I'm humbled thinking of the implications... buying channels p2p...

Balance of Satoshi allows funding from an external wallet, too

Thank you! I've certainly used BOS for batch opens, but never quite figured out the external wallet procedures. If there was a video or step-by-step doing it from Sparrow post-mix it would be fit for the gods!

Thank you! I've come across chaincase before and was immediately interested to say the least. I would like to see this at work in the wild. This is next level.
