Use case · Estate
Protect family records.
Birth certificates, marriage licenses, adoption records, medical histories, insurance policies — the paperwork of family life scattered across drives, safes, and photo apps. Executable custody requires more than folders.
The change: Encrypted vault with beneficiary-aware access + on-chain proof of version.
How it works
Four steps · every step signs a receipt.
Vault every family document with per-file encryption keys derived from your identity
Designate access per document type · spouse sees insurance policies, adult children see medical directives, executor sees the whole estate
Every access emits a signed receipt · you know who opened what, when
On dormancy trigger, records automatically become accessible to their designated recipients — no scrambling in a crisis
Evidence
The proof this actually works.
- Per-file identity-derived keys mean no provider decryption path — not even H33 can read the vault
- Solana anchor for critical documents (medical directives, deeds, birth certificates) gives you third-party time proof
- Field-level sharing means you can share 'the DOB on the passport' without sharing the passport image
- Edge case: A family member without technical skill: guardian recovery uses cryptographic attestation, not memorized codes · designed for non-technical family members
- Edge case: A blended family with different access needs: distribution matrix supports arbitrary per-recipient scopes
