This is a sample Electronic Medical Records Management System built using a Solidity smart contract deployed on the Sepolia Test Network, with a simple HTML + JavaScript frontend.

The project demonstrates how blockchain can be used to securely register users (doctor/patient) and store/view medical records without a centralized server.

• Blockchain-based EMR system (Sepolia testnet)
• Two portals:
  • Doctor Portal
    • Connect wallet (MetaMask preferred)
    • Register as a doctor
    • Create medical records for patients
    • View existing records
  • Patient Portal
    • Connect using a patient wallet
    • Register as a patient
    • View personal medical records
• Admin Page
  • Overview of doctors, patients, and their records
• Frontend built with HTML + JS
• Smart contract located at: contracts/emr.sol

The frontend will not work until you add your contract ABI and contract address.

You must paste these into:

• index.js
• admin.js

1. Open contracts/emr.sol in Remix IDE.
2. Compile the smart contract.
3. Deploy it using Injected Provider (MetaMask) on the Sepolia testnet.
4. Copy:
   • Contract Address (from deployed instance)
   • ABI JSON (from Remix compiler details)

Paste them into your JS files:

const contractABI = [ /* paste ABI here */ ];
const contractAddress = "0xYourContractAddress";
