How It Works

Three steps to protect your legacy

A dead man's switch for the blockchain era. Set it and forget it — until it matters most.

01

Create Your Vault

Choose a plan, designate heirs, set your check-in interval. Deposit MAS or USDC. Attach encrypted files and messages for your beneficiaries.

→
02

Stay Active

Ping periodically to prove you're alive. Miss a check-in and the countdown begins. Fully autonomous — no third parties involved.

→
03

Auto-Distribute

If you stop responding, Massa's Deferred Calls automatically transfer your assets to designated heirs. Guaranteed execution — no oracles, no keepers.

Use Cases

Built for those who plan ahead

Whether you hold crypto, travel to dangerous places, or fight for truth — this is your contingency plan.
