This is the homepage, that check if the user has metamask wallet connected. User can only enter if he has a wallet.
Once user enters the site, we check if he already has a will, if there is no will, we get an option to create a new will
In the will creation page, we enter basic user details and the amount of ETH that he wants to lock in for his heirs
metamask wallets
once you click on submit the metamask wallet triggers to mine a block onto the block chain
after successful insertion, we get a toast message with the transaction hash
User is then redirected to a page that helps him add beneficiaries and any specific sale deeds that the user want to hand over
Once the user fills in details, metamask is again triggered and another block is added with beneficiary details
The IPFS system that stores the sale deed files uploaded by user. They will be retrieved by the beneficiary once the user is confirmed dead.
The etherscan website shows our transactions on the Sepolia Ethereum test nest
If the user already has a will inplace, a link to that transaction block is displayed and a "simulate death" button is used for testing.
Upon hitting the "simulate death event", a mail with the sale deed link and the amount of sepolia eth transferred is notified to beneficiary

💀 Dead Man’s Contract – The Will That Can’t Be Killed!

🚀 Elevator Pitch

Ever heard of family feuds over a will? The classic *“But Grandma wanted me to have the house!”* or “That’s NOT Dad’s signature!”? Yeah, we have too. **Billions in inheritance disputes arise every year due to tampered, lost, or hidden wills, leaving families in chaos instead of closure.

🔗 Enter "Dead Man’s Contract" – a tamper-proof, self-executing decentralized will. Built on Ethereum, it automates inheritance with **smart contracts, ensuring assets are securely distributed exactly as intended. No courts. No shady lawyers. No cousin Steve “accidentally” misplacing the will.

📜 How it works:
1️⃣ Create your blockchain-secured will 📜
2️⃣ Add beneficiaries & asset distribution 🏡💰
3️⃣ Periodically confirm proof-of-life ✅
4️⃣ Upon passing, assets auto-distribute & heirs receive notifications—surprise, you’re rich! 🎉

💀 Death is inevitable. Inheritance disputes don’t have to be. 🚀

📌 Inspiration

Wills are meant to protect legacies, but more often than not, they **tear families apart. Research shows that **inheritance disputes are increasing worldwide, with millions lost to **fraud, forgery, and mismanagement. Worse, these battles **overshadow the mourning process, trapping families in **courtrooms instead of closure.

We thought: What if a will executed itself? No middlemen. No disputes. Just pure, immutable execution of final wishes. That’s why we built **Dead Man’s Contract, leveraging blockchain’s **immutability, transparency, and automation to eliminate legal loopholes and ensure assets go exactly where they should.

📌 What We Learned

🔹 Building a decentralized app (dApp) on Ethereum Sepolia Testnet
🔹 Writing secure Solidity smart contracts
🔹 Interacting with the blockchain via Web3.js, Ethers.js, and MetaMask
🔹 Decentralized file storage with IPFS (Pinata) for notarized wills & sale deeds
🔹 Automating ETH transfers & email notifications via smart contract events

📌 How We Built It

💡 Tech Stack:

Solidity + Ethereum Sepolia Testnet for trustless will execution
React + Ethers.js for frontend integration
Pinata (IPFS) for secure will & property deed storage
Node.js + Nodemailer for beneficiary notifications
MetaMask for seamless blockchain transactions

🛠 Workflow:
1️⃣ User creates a tamper-proof will on the blockchain 📜
2️⃣ Adds beneficiaries, ETH allocations & property deeds 🏡💰
3️⃣ Periodically confirms proof-of-life (because we don’t want to execute the will too soon 👀)
4️⃣ Upon passing, the smart contract auto-distributes funds & sends secure email notifications to beneficiaries (with their inheritance details & IPFS-stored documents).

📌 Challenges We Faced

🚧 Making a will both flexible & trustless—allowing users to update their will while ensuring immutability
🚧 File storage security—storing wills & deeds **decentralized yet retrievable
🚧 Gas fee optimizations—deploying smart contracts efficiently without unnecessary costs 💸
🚧 Handling proof-of-life—ensuring that the will **executes at the right time, without errors

📌 Why It Matters

💀 Death is inevitable, but inheritance disputes don’t have to be. By leveraging blockchain immutability, we eliminate fraud, delays, and tampering—ensuring that a person’s **legacy is preserved exactly as intended. No middlemen, no courtrooms, **just a smart contract doing what it was programmed to do—fairly and transparently.

🚀 Welcome to the future of wills—one that executes itself.
