chantools sweepremoteclosed

Go through all the addresses that could have funds of channels that were force-closed by the remote party. A public block explorer is queried for each address and if any balance is found, all funds are swept to a given address

Synopsis

This command helps users sweep funds that are in outputs of channels that were force-closed by the remote party. This command only needs to be used if no channel.backup file is available. By manually contacting the remote peers and asking them to force-close the channels, the funds can be swept after the force-close transaction was confirmed.

Supported remote force-closed channel types are:

STATIC_REMOTE_KEY (a.k.a. tweakless channels)
ANCHOR (a.k.a. anchor output channels)
SIMPLE_TAPROOT (a.k.a. simple taproot channels)
