What should I be looking for in a keyholder to my bitcoin estate plan?

Consider designating a trusted individual to hold one of your keys.

In the case of Unchained vaults, two keys are always required to move the bitcoin and Unchained only holds one. Therefore, you absolutely must have a plan to effectively pass a key to inheritors. For this purpose, you can use the Unchained Inheritance Protocol.

Your keyholder should be trustworthy and you should have a high level of communication with them while you are still alive. The keyholder should have access to a secure storage location such as a safety deposit box, home safe, or other secure location where they can store the tamper-evident bag that comes with the Unchained inheritance materials.

Change your keyholder if needed.

If your keyholder is unable or unwilling to continue holding a key to your vault, you should consider that key “compromised” and replace it. Every vault that the key secures should be updated to use the new key. Once the vaults are updated, a new key could be provided to a new keyholder and the old key can be marked as compromised and archived.
