Inheritance

What happens to your crypto if you're gone?

Billions in crypto are lost every year because there's no plan. Cardra's on-chain inheritance vault ensures your assets reach the right people — automatically.

Regular check-ins
Every 30, 60, or 90 days
Confirm activity on your schedule. If you miss a check-in, the grace period begins automatically.
Named beneficiaries
Up to 10 beneficiaries
Assign wallet addresses that receive your funds. Split allocations however you want.
Configurable grace period
30-365 day window
Set how long the system waits after a missed check-in before distributing funds.
Automatic distribution
100% trustless
After the grace period, funds transfer on-chain to your beneficiaries — no intermediaries, no lawyers.
