The Anatomy of the Switch

A Dead Man's Switch is a mechanism designed to be activated if the human operator becomes incapacitated. In the context of digital inheritance, it is the trigger that automatically releases a user's encrypted vault to their heirs.

  1. The Check-in: The user establishes a heartbeat or "Proof of Liveness." This might involve connecting their wallet and signing a transaction every 6, 12, or 24 months.
  2. The Contestation Period: If a check-in is missed, the system enters a grace period (default: 30 days, configurable 14–180). During this time, the user is aggressively notified via multiple channels to prevent an accidental trigger.
  3. The Execution: If the contestation period expires without a check-in, the smart contract automatically changes state, granting the predefined heirs access to decrypt the vault.

Decentralization is Key

A centralized Dead Man's Switch relies on a traditional server cron job, which can fail if the company shuts down. A decentralized switch uses blockchain consensus and decentralized keeper networks to guarantee execution. The code is law, and the execution is inevitable, ensuring the transfer of your assets exactly as programmed.
