Nunchuk vs Casa: self-hosted multisig vs. collaborative custody
Both move you beyond a single hardware wallet's single point of failure. Nunchuk is free and you hold every key. Casa charges an annual fee and holds one key for you as a recovery backstop.

OUR VERDICT
Pick Nunchuk if you're comfortable managing every key yourself and don't want a recurring fee. Pick Casa if you want a professionally managed recovery key and guided inheritance planning as part of the deal.
Common questions
Does Casa holding one key reduce my security?
Not meaningfully — Casa's key alone can't move funds without yours, and it exists specifically as a recovery backstop if you lose access to your own keys.
