chantools rescueclosed

Try finding the private keys for funds that are in outputs of remotely force-closed channels

Synopsis

If channels have already been force-closed by the remote peer, this command tries to find the private keys to sweep the funds from the output that belongs to our side. This can only be used if we have a channel DB that contains the latest commit point. Normally you would use SCB to get the funds from those channels. But this method can help if the other node doesn't know about the channels any more but we still have the channel.db from the moment they force-closed.

The alternative use case for this command is if you got the commit point by running the fund-recovery branch of my guggero/lnd fork in combination with the fakechanbackup command. Then you need to specify the --commit_point and --force_close_addr flags instead of the --channeldb and --fromsummary flags.

	--commit_point 03xxxx

Options

      --bip39                     read a classic BIP39 seed and passphrase from the terminal instead of asking for lnd seed format or providing the --rootkey flag
      --channeldb string          lnd channel.db file to use for rescuing force-closed channels
      --commit_point string       the commit point that was obtained from the logs after running the fund-recovery branch of guggero/lnd
      --force_close_addr string   the address the channel was force closed to
      --fromchanneldb string      channel input is in the format of an lnd channel.db file
      --fromsummary string        channel input is in the format of chantool's channel summary; specify '-' to read from stdin
  -h, --help                      help for rescueclosed
      --listchannels string       channel input is in the format of lncli's listchannels format; specify '-' to read from stdin
      --pendingchannels string    channel input is in the format of lncli's pendingchannels format; specify '-' to read from stdin
