Agreed, that was in the details below: - HTLC-timeout and HTLC-success txs sigs are SIGHASH_ANYONECANPAY|SIGHASH_SINGLE, so you can Bring Your Own Fees. The only problem with these proposals is that it requires you have an available UTXO to make the CPFP etc. Cheers, Rusty. _______________________________________________ Lightning-dev mailing list Lightningemail@example.com https://lists.linuxfoundation.org/mailman/listinfo/lightning-dev
