Automate Inheritance with Smart Contract-Based Will Execution

Design a tamper-proof digital testament system that leverages smart contracts to release assets to beneficiaries upon verified proof of death or legal trigger.

Why Use Smart Contracts for Wills?

Traditional will execution is slow, involves legal intermediaries, and can be contested or delayed. Smart contracts ensure that asset distribution occurs exactly as intended, automatically and transparently, based on pre-coded conditions and verified events.

Project Objective

Create a platform where individuals can draft digital wills and designate beneficiaries. The smart contract securely holds crypto assets and releases them to listed recipients upon submission of a death certificate or verified oracle trigger.

Key Features of the Will Executor System

Beneficiary Assignment & Split

Testators can assign multiple beneficiaries and percentage-based asset distribution logic.

Conditional Asset Release

Assets are transferred only upon a verified death event using oracles or trusted authority input.

On-Chain Will Visibility

The will metadata and structure can be verified by all parties, ensuring no ambiguity or manipulation.

Role-Based Access

Testator, executor, and oracle roles are managed through wallet-based permissions.

System Architecture Overview

Users interact with the smart contract to define beneficiaries, allocate funds, and assign executors. The contract holds crypto assets in escrow. Upon oracle verification (e.g., death certificate or legal confirmation), the contract disburses funds accordingly, with all actions recorded immutably.

Recommended Tech Stack

Blockchain

Ethereum or Polygon for asset-holding smart contracts

Smart Contracts

Solidity for will creation, fund locking, and distribution

Oracle Service

Chainlink for verifying off-chain events like death certificates

Frontend

React.js + Web3.js for user dashboard and status updates

Development Roadmap

1. Build the Will Executor Contract

Allow testators to assign assets and define beneficiary rules within the smart contract.

2. Integrate Oracle Verification

Use Chainlink oracles to confirm proof of death before releasing funds.

3. Create Dashboard for Testators and Executors

Enable secure login, will creation, and role assignment using wallets.

4. Add Encryption and IPFS Storage

Encrypt will metadata and optionally store files off-chain with links recorded on-chain.

5. Simulate Inheritance Flows on Testnet

Run scenarios for asset allocation, proof triggering, and fund disbursement with mock users.
