What is important to be RBF-able is the punishment transaction which spends the commitment transaction. Fortunately: 1. The punishment branch of the commitment SCRIPT has no CSV, so it can be spent immediately to get the old commitment confirmed via CPFP. 2. The punishment branch requires only a single signature from one node, making RBF trivial. I believe at least lnd already does RBF for breach claim transactions, I will have to review c-lightning code to see if onchaind does so. I vaguely remember it being brought up some time ago for c-lightning. Regards, ZmnSCPxj -------------- next part -------------- An HTML attachment was scrubbed... URL:
