Use case · Estate

Share estate plans.

Executors need to see the will. Beneficiaries should see only what applies to them. Attorneys review the whole plan. Financial advisors need account details but not personal notes. Traditional sharing leaks everything to everyone.

The change: Field-level sharing with per-recipient policy + cryptographic receipts.

How it works

Four steps · every step signs a receipt.

1

Notarize the estate plan on-chain at signing · Dilithium + Solana anchor

2

Distribute per role: executor sees full plan, beneficiaries see their allocations, attorney sees whole plan, financial advisor sees account details only

3

Recipients are identity-attested before decryption · a leaked link to the wrong person does nothing

4

Every access is signed-audit-logged · exportable at any time

Evidence

The proof this actually works.

  • Distribution matrix is field-level and per-recipient (see /features/distribution-matrix/)
  • Notarization to Solana is a third-party time proof any court can verify
  • Revocation is cryptographic · if a beneficiary designation changes, the old view stops decrypting on the recipient's device
  • Edge case: Contested plans: every version is on-chain with a signed hash · nobody can claim 'there was a later version'
  • Edge case: International beneficiaries: the identity attestation works across borders without requiring the beneficiary to register with a jurisdiction-specific service
