May be that I miss something of LN protocol so apologies for that .. Let's assume that due to a pendind htlc a channel got closed (non collaborative), who close that? The peer nodes who has the channel on it? Who pays for the closure ?on this kind of multisig transactions could both members apply for cpfp ? And what about rbf? could both apply for that? ... I'm wondering if the one who need to pay more for the non collaborative closure it is always the child one :)
