What is CitadelVault
CitadelVault is a purpose-built, air-gapped computer that guides anyone through securing their Bitcoin inheritance in 45 minutes: no advisor, no cloud, no subscription required. It runs the 21sats Inheritance Protocol, the same methodology we refined through years of real client work across dozens of jurisdictions. One device. One setup. Generational protection.
Never touches the internet, by design
The 21sats Wizard guides every step
M-Disc archival rated to outlast generations
Court-ready legal documents, built in
Dead man's switch on the blockchain (patent pending)

Prague · June 12
We've rented a private apartment in the heart of Prague for one evening during the conference. Early enough that you can still make it to whatever comes next. Small gathering, not a party, not a booth, not a pitch night. If you're the kind of person who belongs in a room like this, you already know it.
