chantools sweeptimelockmanual

Sweep the force-closed state of a single channel manually if only a channel backup file is available

Synopsis

Sweep the locally force closed state of a single channel manually if only a channel backup file is available. This can only be used if a channel is force closed from the local node but then that node's state is lost and only the channel.backup file is available.

To get the value for --remoterevbasepoint you must use the dumpbackup command, then look up the value for RemoteChanCfg -> RevocationBasePoint -> PubKey.

To get the value for --timelockaddr you must look up the channel's funding output on chain, then follow it to the force close output. The time locked address is always the one that's longer (because it's P2WSH and not P2PKH).

      --rootkey string              BIP32 HD root key of the wallet to use for deriving keys; leave empty to prompt for lnd 24 word aezeed
      --sweepaddr string            address to sweep the funds to
      --timelockaddr string         address of the time locked commitment output where the funds are stuck in
