That's a question I haven't delved reply enough to answer. Probably a better question for Obi Nwosu (or maybe @Jeff Booth). I just know that as it's ecash it comes with much better privacy than Spark or conventional custodians. But beating that rug risk is indeed the holy grail...

Tested and ran early builds of fedi, the app guides you through a signing ceremony for your federation guardians and then connects LN infra to your instance. The federation is only in terms of who is the mint custodians, not the infra below it. The app then developed a lot more, worth trying out and checking their integrated app ecosystem
