But once you start frequently bridging across chains and signing back and forth, one slip of your hand is all it takes—you’ll regret it for half a month. Multi-signature is more like a team or a family ledger. When the amounts get larger, splitting responsibility can be genuinely useful, but the management overhead is real too: once you have more people involved, it’s easy to get stuck on “who isn’t online.” Social recovery sounds great; if you lose access, it can save you.
