Haven’t seen anything. Biggest risk ATM is that the phone home functionality could identify your ip (and residence) as a bitcoin person who owns a blockclock
Air gap- a computer that never has and never will be connected to a network is a big task. If you have 3 signers and at least one of them is a hardware wallet, should you trust that multisig with 2 bitcoin?
Agree. No offline computer for me (OSUpdates are tough), but multipoint with mixed HWWs. When one balance gets too high, time for a new multisig. Just like you need more than one bank product, you’re going to need multiple multi sigma if you’re lucky enough to save a lot of value
