The problem InheritChain solves

🚨 The Problem We Solve

• 🔐 Lost Access to Assets:
  Private keys die with the owner—no way to recover funds once they're gone.

• 🌐 Fragmented Across Chains:
  Digital assets live on multiple blockchains (Ethereum, Polygon, Avalanche, etc.), making inheritance manual, technical, and error-prone.

• ⚖️ No Legal or Technical Standard:
  Traditional wills can't handle smart contracts or on-chain assets, leaving beneficiaries in a legal gray area.

✅ How InheritChain Solves It

• 🧾 On-Chain Will Registry:
  Create tamper-proof, blockchain-based wills with off-chain metadata for privacy.

• 🕒 Time-Locked Challenge Window:
  A 10-day dispute period managed via Chainlink Automation ensures fairness.

• 🔗 Seamless Cross-Chain Transfers:
  Chainlink CCIP automates fund distribution across all supported blockchains.

• 🧠 Off-Chain Truth via Chainlink Functions:
  Verifies if the testator is deceased using a real-world data API—resolving disputes trustlessly.

• 🖥️ Simple & Secure Interface:
  Intuitive UI for testators and beneficiaries—no technical expertise required

Challenges we ran into

⚠️ Development Challenges Faced

• 🪦 No Real Death Registry API
  Could not find a publicly accessible or reliable death verification API for on-chain use.
  → Used a simulated government API as a placeholder.

• 💧 Shortage of Testnet Faucets
  Constant difficulty in acquiring testnet ETH, MATIC, across Sepolia and Polygon
  → Slowed down contract deployment and cross-chain testing.

• 🔄 Complex CCIP Testing
  Debugging and testing Chainlink CCIP messaging between multiple chains was time-consuming .

• ⛽ Gas Cost Optimization
  Implementing Automation and CCIP together meant optimizing contract calls to stay within gas limits and callback constraints.
