PharmaChain envisions a world where the pharmaceutical supply chain is fully transparent, secure, and tamper-proof. By leveraging blockchain technology, PharmaChain ensures that pharmaceutical products are tracked in real time from the point of production to the point of sale, preventing counterfeit drugs, improving traceability, and building trust within the industry. Our goal is to revolutionize supply chain management by providing an immutable record of every transaction, ensuring the authenticity and integrity of pharmaceutical products globally.

About the Project

PharmaChain is a decentralized supply chain management platform built on blockchain technology. It is designed to securely track the movement of pharmaceutical products from manufacturers to pharmacies or hospitals. The project leverages the Bitfinity Testnet to ensure transparency, immutability, and verifiability of drug shipments using smart contracts.

By utilizing blockchain, the project aims to:

• • • Prevent fraud in the pharmaceutical industry.
    • Enhance transparency across the entire supply chain.
    • Ensure the authenticity and integrity of pharmaceutical drugs from production to delivery.

    Tech Stack

• • • Blockchain Framework: Hardhat
    • Smart Contracts: Solidity (with OpenZeppelin Contracts)
    • Frontend: React.js
    • Styling: TailwindCSS
  • Libraries
    • Ethers.js (to interact with Ethereum blockchain)
    • React Router (for routing)
    • OpenZeppelin Contracts (for standard smart contract features)
    • Vite (for bundling and development)

Installation

Prerequisites

Ensure you have the following tools installed on your system:

• • • Node.js (v16 or higher) – for running JavaScript code on the server.
    • MetaMask – for connecting to the blockchain network.
    • Git – for version control and repository management.
    • A code editor like VS Code.

Steps

1. 1. 1. Clone the Repository:

         git clone https://github.com/hatim85/Supply-chain.git
         cd Supply-chain
         

      2. Install Dependencies: npm install

      3. Install Frontend Dependencies: cd ICP-Frontend npm install

      4. Set Up Environment Variables: Create a .env file and add the following: VITE_APP_INFURA_PROJECT_ID=your_infura_project_id VITE_APP_CONTRACT_ADDRESS=your_deployed_contract_address_on_bitfinity_testnet

      5. Run the Application: To start the frontend: npm run dev

Usage

1. 1. 1. Connect Wallet: Ensure MetaMask is installed and connected to the Bitfinity Testnet. You can then interact with the PharmaChain application to: Track drug shipments from manufacturers to distributors. Approve transfer requests. View transaction histories and drug movement data.

      2. Managing Supply Chain: Use the frontend interface to create new drug batches, approve requests, and transfer drugs across different participants (e.g., manufacturers, distributors).

      3. Track Shipments: The smart contracts ensure that all transaction data is recorded on the blockchain, making it easy to track the movement of each batch of drugs.

Smart Contract Deployment The PharmaChain smart contracts have been deployed on the Bitfinity Testnet.

Deployment on Bitfinity Testnet To deploy the contracts on the Bitfinity Testnet, follow these steps:

1. 1. 1. Configure Hardhat: In your hardhat.config.js, add the configuration for the Bitfinity Testnet:require(“@nomicfoundation/hardhat-ethers”);
      2. module.exports = { networks: { bitfinityTestnet: { url: “https://testnet.bitfinity.network“, accounts: [0x${process.env.PRIVATE_KEY}], }, }, solidity: “0.8.19”, };
      3. Deploy Contracts: To deploy the contracts on Bitfinity, run the following command: npx hardhat run scripts/deploy.js –network bitfinityTestnet
      4. Update Environment Variables: After deploying the contract, update the .env file in the ICP-Frontend directory with the deployed contract address: VITE_CONTRACT_ADDRESS=your_deployed_contract_address
