You did everything right. Hardware wallet. Seed phrase stamped in steel. A passphrase only you know.
That is also exactly how Bitcoin can disappear for your family if something happens to YOU.
By some estimates, 3 to 4 million coins are already gone for good. Close to a fifth of everything that will ever exist. Not hacked. Not sold. Abandoned, because the one person who held the keys was the only one who could reach them.
Self-custody answers "who can take my Bitcoin." It says nothing about "who can reach it when I can't." A seed on a steel plate is a component, not a plan. Your family cannot inherit what they can't decode.
A new device is built for exactly this gap. CitadelVault is an air-gapped inheritance computer that encrypts your keys and instructions offline, splits recovery across NFC cards you scatter across separate locations (any 2 of 3 rebuild access), and ships with the legal documents heirs actually need. No subscription. No custodian. No KYC. The recovery scripts are open source and run without the company in the loop.
It is very new, still pre-order, and the third-party audit lands later this year, so verify before you trust it. But the problem it targets is as old as self-custody itself.
Holding your own keys is half the work. Making sure your family can still hold them after you is the other half.
