10:58 < provoostenator> justinmoon: c-lightning uses libwally, which is about to add PSBT support: https://github.com/ElementsProject/libwally-core/pull/126
11:00 < provoostenator> So maybe c-lightning could use that to return a PSBT for its fundchannel_start / fundchannel_complete flow, though not sure if that's useful
11:10 < justinmoon> provoostenator: passing a psbt to fundchannel_complete could be advantageous. Perhaps c-lightning could do some checks to make sure that the transaction was constructed properly. Currently it just blindly commits to an outpoint ...
11:11 < provoostenator> The other way around, is there any useful from c-lightning to the hardware wallet?
11:11 < provoostenator> And is there a way yet to make channel closings end up back on the hardware wallet?
11:12 < provoostenator> The latter purely as a convenience; as long as the hardware wallet doesn't sign intermediate updates, there's no security benefit there.
11:13 < justinmoon> Once this PR makes it into a release, we'll be able to close channels to hardware wallet addresses: https://github.com/ElementsProject/lightning/pull/3116
11:17 < justinmoon> I don't think there's anything useful c-lightning can tell the hardware wallet. fundchannel_start currently just returns an address. Until hardware wallets can somehow register your c-lightning node xpub it wouldn't be able to validate that this address is controlled by your node.
11:18 < justinmoon> (i'm no lightning expert ... could be wrong here)
11:27 < instagibbs> sortedmulti already merged, that was fast

11:34 < justinmoon> Fantastic
