Dead Man's
Proof
What is sealed cannot be unseen.
What is attested cannot be denied.
How it works
Deposit your data
Submit private information to your personal vault. A cryptographic hash is committed onchain. Nobody sees the raw data. What enters the vault does not leave.
Ask yes or no questions
Anyone with access can submit natural language queries against your sealed vault. Questions are answered without exposing the underlying data. The dead tell no tales willingly.
Truth without secrets
An AI agent verifies claims against your sealed data and produces a cryptographic attestation. The proof is public. The data never leaves the vault. So it is written; so it is done.
Sample attestation
"Does the depositor hold more than 10 ETH?"
The depositor holds more than 10 ETH. Verified against sealed vault data.

Seal sensitive information. Let anyone query it. Produce verifiable attestations. Your secrets never leave the vault.
