There is a degree of centralization here, correct? Not entirely trust less? I'm asking though I'm willing to make trade offs depending on the situation.

How does it work?

This is really awesome!

Amboss is really doing some great work, I can't wait for a locally hosted version you can have on your node and if you could have their services plugged into something like Ride the Lightning so you can manage your LN node like a legend

Amazing. Amboss keeps delivering.
