AfterLife-Protocol 🏛️

Decentralized Digital Inheritance Protocol for Ethereum

AfterLife-Protocol is a revolutionary blockchain-based solution that enables secure, transparent, and automated digital inheritance of cryptocurrency assets. Built on Ethereum, it allows users to create digital wills, designate beneficiaries, and ensure their crypto assets are distributed according to their wishes after periods of inactivity.

   forge install

3. Set up environment variables

   # frontend (.env)
   VITE_CONTRACT_ADDRESS=your_contract_address
   VITE_HTTP_RPC_URL=your_network_url
   
   # smartContract (.env)
   PRIVATE_KEY=your_private_key
   RPC_URL=your_rpc_url

4. Deploy smart contract

   cd smartContract
   forge script script/Deploy.s.sol --rpc-url $RPC_URL --private-key $PRIVATE_KEY --broadcast

5. Start the frontend

   cd frontend
