One way of protecting yourself against losing money as a result of bugs and crashes in your Lightning node implementation software (e.g. the recent LND bug) is to run a watchtower yourself or employ an external watchtower. A watchtower can broadcast a justice transaction if a channel counterparty broadcasts a revoked state to exploit your Lightning node downtime.
What is the current status of watchtower implementations in October 2022? Are they mature? Are they widely in use? Do they support the various Lightning implementations?
