Your Digital Legacy,
Secured Forever.
Hardware-backed cryptographic vault. Autonomous unlock.
Blockchain-powered digital inheritance.
Digital Assets Disappear.
Centralized Systems Fail
LastPass, Uber, T-Mobile — billions of records leak every year. Even your password managers get hacked. Single server = single point of failure.
Death = Data Loss
Over $140 billion in crypto is permanently inaccessible. When the owner dies, digital assets — passwords, wallets, documents — are lost forever.
Current Tools Fall Short
Either you trust a centralized authority (1Password, Bitwarden), or struggle with complex technical setups (multisig).

Six Cryptographic Layers
Context Vector
HKDF-SHA256 + Fuzzy Extractor derives keys from your environment. No password to remember — your location is your key.
Reed-Solomon ECC
Error-correcting codes over GF(2⁸) tolerate GPS drift. Your vault opens even if conditions shift slightly.
Shamir Secret Sharing
K-of-N threshold key splitting. No single point of failure — reconstruct the master key from any K shares.
ECIES Inheritance
Heir's share encrypted with secp256k1 (Ethereum-compatible). Only they can decrypt when the time comes.
Decoy Vault
Under duress, enter a different TOTP code — a fake vault opens. The attacker never knows the real vault exists. Timing-safe comparison.
Zero-Knowledge
The server stores only encrypted blobs. No decryption capability on the backend — ever. Your keys never leave your device.
