Don't Let Your Crypto Die With You

We never move your funds. On Avalanche C-Chain, when verified inactivity and biometric proof confirm eligibility, we transfer access rights to your beneficiaries.

What is Zelf Legacy?

It solves one of the most critical problems in crypto: "What happens to your assets when you die?"

Unlike traditional solutions that require transferring funds to a third-party or smart contract, Zelf Legacy focuses on access inheritance. We do not move your funds. We securely transmit access rights to your designated beneficiary only upon verified inactivity and rigorous biometric proof.

How it Works

A secure, private, and automated protocol

0101 / 06

1. Create your Will

Open Zelf Legacy from your wallet

The flow starts inside the wallet itself. Open the account menu, enter Zelf Legacy, and begin creating an inheritance plan without leaving the main app experience.

Enable "Legacy Mode" and designate your beneficiary. You provide their details and a verification photo, ensuring only they can claim access.

2. Lawyer Attestation

Access Lawyer Dashboard from wallet

The lawyer opens Zelf Legacy from their wallet or the dedicated lawyer portal to view and manage pending attestation requests.

A licensed lawyer reviews pending attestations from their dashboard, verifies vault details, and completes biometric identity verification before approving the will on-chain.

3. Heartbeat Protocol

Open your Legacy dashboard

The testator opens Zelf Legacy and taps "Update liveness" to initiate a new heartbeat proof before the inactivity timer expires.

Your Zelf app sends periodic cryptographic heartbeats to the Avalanche C-Chain inheritance contract, proving you are active. Signals are privacy-preserving and tamper-proof. When the timer reaches zero, the inheritance protocol activates.

4. Lawyer Execution Approval

Access Lawyer Dashboard from wallet

The lawyer opens the app in lawyer.zelf context and navigates to the Lawyer Dashboard to view legacies awaiting action.

When the inactivity period and grace period expire without a heartbeat, the Guardian Oracle notifies the lawyer. The lawyer reviews the vault, verifies their identity, and approves execution on-chain so the will becomes claimable by beneficiaries.

5. Secure Claim

An inheritance is ready to claim

The beneficiary receives a secure notice that a Zelf Legacy plan is now available and can begin the guided claim flow.

After the inactivity period and grace period expire, your beneficiary can claim the legacy. We use ZelfProof biometric verification to ensure it's truly them.

Why Zelf Legacy?

Non-Custodial

No funds are ever transferred to a contract. You retain full control until the moment of inheritance.

Privacy First

ZK-compressed heartbeat signals are anonymized. No one knows you have a setup.

Triple Layer Security

Biometric Face Matching + ID Verification + Zero-Knowledge Unlocking ensures only your true beneficiary gets access.

Avalanche Development Roadmap

Three tranches delivering biometric inheritance infrastructure native to the Avalanche ecosystem (Fuji → C-Chain mainnet).

Tranche 1In Progress

MVP — EVM contract + ZelfProof on Fuji

5 weeks
  • Inheritance registry smart contract deployed on Avalanche Fuji (C-Chain testnet)
  • ZelfProof biometric verification integrated on-chain
  • Policy creation: single-party and multiparty wills, lawyer role, Shamir's Secret Sharing
  • Heartbeat protocol with verifiable history (events + client proofs)
  • End-to-end inheritance simulation on Fuji with Snowtrace-verifiable txs
  • Public GitHub repo: unit tests, integration tests, Hardhat/Foundry deployment scripts
Read more details
Tranche 2

Testnet — Guardian Oracle + claim pipeline

6 weeks
  • Guardian Oracle service with EVM-compatible interface (Chainlink-style readiness)
  • Lawyer notification system with fallback to direct beneficiary alerts
  • Claim verification pipeline with client-side ZelfProof matching
  • Full workflow test: policy creation through seed phrase reconstruction
  • Oracle interface specification, monitoring, and security model documentation
Read more details
Tranche 3

Mainnet — Android UI, SDKs & launch

6 weeks
  • Wallet integration modules for Core-compatible wallets on Avalanche C-Chain
  • Developer SDK + contract ABIs for integrators (npm package)
  • Demo applications: Web Extension; Android UI (priority); iOS
  • Production contracts deployed on Avalanche C-Chain mainnet
  • Developer documentation with architecture diagrams and video tutorials
  • Onboarding and claim UX flows with usability testing
