Why Crypto Needs a Dead Man's Switch

Cryptocurrency is the asset class most vulnerable to permanent loss through incapacitation. Unlike bank accounts (which have beneficiary designations), stocks (which pass through brokerages), or real estate (which has titles), cryptocurrency exists only through private keys.

If those keys are lost — through death, disability, imprisonment, or simple forgetfulness — the crypto is gone. A dead man's switch solves this by automatically releasing the key information to a designated heir when the holder stops checking in.

For crypto holders, this isn't a nice-to-have. It's essential insurance against the permanent loss of potentially life-changing assets.

Setting Up a Crypto Dead Man's Switch

Step 1: Choose Your Content Your vault should contain: • Seed phrases for all self-custody wallets • Hardware wallet PINs • Exchange account credentials • 2FA backup codes • A complete asset inventory with approximate values • Step-by-step instructions for a non-technical person • Your heir contact information for any OTC desks or custodians

Step 2: Encrypt and Upload Using ZeroLatch: • Create a vault named "Crypto Recovery" • Choose a strong encryption password (different from your account password) • Upload a document containing all the above information • Share the encryption password with your heir through a separate secure channel (in-person, sealed envelope)

Step 3: Configure the Switch • Set check-in interval (14-30 days recommended for crypto) • Designate your heir as recipient • Include a message explaining what the vault contains and what to do

Step 4: Maintain • Check in regularly (set calendar reminders) • Update the vault contents when your holdings change significantly • Test the process with your heir

Security Considerations

Separation of concerns: The vault contains encrypted information. The Private password or recovery phrase is shared separately. Even if someone intercepts the vault release notification, they can't read the contents without the password.

Timing: Choose an interval that balances false-positive prevention with timely access. Crypto markets move fast — if your positions include leveraged or time-sensitive DeFi positions, a shorter interval may be appropriate.

Multiple vaults: Consider separate vaults for different risk levels — one for exchange credentials (lower risk), another for self-custody seed phrases (highest risk).

Encryption boundary: ZeroLatch uploads ciphertext rather than plaintext. Simple mode permits authorised assisted recovery, while Private mode requires a password or recovery phrase ZeroLatch does not store. Browser encryption reduces server-side plaintext exposure, but the security of the result still depends on endpoint security, recovery-code handling, recipient security, and the selected mode.
