LegacyVault Utilization

Platform Benefits

For Asset Owners (The "Proactive" Hodler)

LegacyVault provides peace of mind that your digital assets will never be lost.

• Intermediary-Free Protection

  • Problem: "If I have an accident tomorrow, no one knows my private key."

  • Solution: Set a "Heartbeat" (e.g., 6 months). As long as you ping, your assets are safe. If not, they are automatically transferred.

• Passive Income (Yield)

  • Your assets don't just sit idle. Funds stored in the Vault automatically enter the Lending Pool.

  • Enjoy 1% compound interest (simulated) calculated in real-time by the Rust smart contract.

• Full Flexibility

  • Deposit or Withdraw funds anytime while you are alive (Status: Active).

For Beneficiaries

LegacyVault turns the complex inheritance process into a single button click.

• Claiming Without Bureaucracy

  • Problem: Inheritance courts take months and cost a fortune.

  • Solution: Once the timer expires, the Claim button becomes active. No lawyers, no notaries needed.

• Receive More

  • Beneficiaries receive Principal + Accumulated Interest. The inheritance grows over time.

For the Ecosystem (Developers & Network)

LegacyVault contributes to Arbitrum's technical landscape.

• Stylus Demonstration: Showcases Rust's performance in handling complex state and loops.

• Long-Term Liquidity: Encourages long-term asset retention (TVL) on the Arbitrum network.

Use Cases

1

The Responsible Father

• User: Budi, a crypto investor.

• Action: Budi creates a Vault, sets his wife as the Beneficiary, and sets a 1-year Ping interval. He deposits 10,000 USDC.

• Result: Budi Pings every birthday. His money grows 1% daily in the pool. If something happens to him, his wife is secured.

2

Education Savings (Time-Lock)

• User: Siti, wants to save for her child's tuition.

• Action: Siti uses LegacyVault not for death, but as a disciplined locking mechanism. She sets a short timer but rarely Pings unless adding funds.

• Result: Compound interest keeps running, maximizing the savings value for her child's future.

3

Dead Man's Switch for Journalists/Activists

• User: Alex, an investigative journalist.

• Action: Alex stores critical documents (as hashes on IPFS/Note) or operational funds in a Vault directed to a public address if he "disappears."

• Result: If Alex is detained or cannot access the internet for 3 months, the funds/information are automatically released to the public/colleagues.

Future Integrations

LegacyVault aims to integrate with leading infrastructure:

• Chainlink Automation: For automatic "Pings" or notifications when deadlines are approaching.

• Lending Protocols (Aave/Compound): In the future, Yield will be sourced from external DeFi protocols (Real Yield) via contract integration, rather than just internal simulation.

• Notification Service (EPNS): Sending notifications to the Beneficiary's wallet when funds are ready to claim.

Vision: To become the Gold Standard for Digital Asset Inheritance—secure, permissionless, and productive.
