lnrpc.ChannelCloseSummary does not give remote channel balance on close. We can derive it.
remote balance = channel capacity - local balance - sum(pending htlcs) - commit fee(miner fee) - any anchors
the pending htlcs, commit fee, and anchors are inside the resolutions field
Bought some @npub18tcc...2nxx giftcards. Wanted to pay over a specific channel to gain some inbound. Ended up using lncli sendpayment --outgoing_chan_id along with the provided pay_req invoice. Worked no problem. Any GUI tools provide this "first hop" selection?
