Field notes
The vault uses three YubiKeys as a native SegWit 2-of-3 multisig, with each key generated and retained inside the card’s OpenPGP applet. The page walks through transaction construction, output and fee review, sequential key use, PIN entry, and physical touch. It also encrypts the vault file, cache, and attached photos, tying recovery to the Mac Keychain and individual keys. The author explicitly separates protection against stolen computers from the unresolved risk of approving a dishonest transaction.
