Also didn’t mean to imply I’ve used lnmux in prod. I experimented with early versions in a lab, and haven’t tried it in a while but there’s been progress based on git activity. They have a great introductory blog post.

It relies on htlc interception, which has been in production use for a while now. That starts getting into what I would consider protocol territory (moreso than infra) and requires deep integration with backend app logic. It’s worth learning about once you have a solid grasp of fundamentals in both distributed systems and LN.
