What is Dead Man's Switch?
An automated trigger that fires when someone stops responding.
Definition
A dead man's switch is a mechanism that automatically executes a pre-set action if the operator fails to periodically confirm they are still alive and in control. Originally used in rail and machinery safety, the concept is now applied in digital systems to automate the release of sensitive information after sustained inactivity.
How It Works
In crypto and digital asset management, a dead man's switch monitors check-in activity. If an owner stops responding to periodic prompts — due to death, incapacitation, or prolonged absence — the switch fires and executes the designated action, such as granting an heir access to a vault. Well-designed systems send multiple warnings before triggering, to prevent accidental activation. The inactivity window is typically configurable: 7 days to 365 days depending on the use case.
How VaultPass Uses This
VaultPass's Sentinel Pulse is a cryptographic dead man's switch. You set a check-in interval. If you miss it, VaultPass sends three warning emails at 80%, 90%, and 100% of your interval. Only a sustained, unresponsive period triggers the heir notification. Your vault remains locked until the switch fires — not one second before.
Common Questions
Can a dead man's switch fire accidentally?
Not with proper design. VaultPass sends three escalating warning emails before triggering. You can cancel from any email with a single click.
How long does a dead man's switch inactivity window typically last?
It varies. VaultPass offers 7-day, 180-day, and 365-day windows. Most users choose 30–90 days as a balance between safety and convenience.
Is a dead man's switch legal for crypto inheritance?
Yes. A dead man's switch is a software mechanism, not a legal instrument. It complements — but doesn't replace — a formal will or trust. Consult an estate attorney for your jurisdiction.
