1/ On wallet backup structure I recently finished migrating from a simple hardware wallet setup to a more secure @safe setup and thought a lot about details like signers, hardware wallets, seed phrases and locations where to store all of this. Doing so I found little information that went beyond "set up a 2/3 multisig" so here are some thoughts. Note that this setup is neither my exact personal setup nor that it is perfect. Rather see it as a starting point from where to refine towards a setup that makes sense for you. It is a very secure setup, but still has a couple of convenience features.
