Kisansetu

KisanSetu is a comprehensive and innovative platform designed to revolutionize the agricultural sector by facilitating assured contract farming agreements between farmers and buyers. With KisanSetu, we aim to bridge the gap between small-scale farmers and large-scale buyers, ensuring both parties benefit from secure, transparent, and mutually beneficial contracts.

The platform leverages blockchain technology and integrates modern web solutions to create a seamless and efficient user experience for both farmers and buyers. Our system enables direct and fair negotiations, enhances communication, and guarantees timely payments through automated smart contracts, thereby promoting trust and long-term partnerships.

Key Benefits

• Empower Farmers: By giving farmers direct access to a broader marketplace, KisanSetu enables them to negotiate fair prices for their crops without relying on middlemen, ensuring they receive better profits.
• Buyer Confidence: Buyers, including large-scale retailers, processors, and exporters, can rely on blockchain-backed contracts to assure quality, timely delivery, and fair prices for agricultural products.
• Efficient Dispute Resolution: Smart contracts help reduce the likelihood of disputes, and in case of disagreements, the platform’s transparent nature makes it easy to resolve issues through mutual consensus.
• Access to Insights: KisanSetu provides real-time market insights, helping both farmers and buyers make data-driven decisions regarding crop pricing, market demand, and supply chain management. Simplified User Experience: Farmers and buyers, many of whom are not well-versed in blockchain technology, can interact with a simple, user-friendly interface that abstracts the complexity of blockchain, offering an intuitive experience.

Features

• Secure Contracts: Use blockchain smart contracts to ensure the integrity of agreements between farmers and buyers.
• Timely Payments: Automate payments and ensure timely transactions through the smart contract system.
• Transparent Communication: Integrated communication tools for direct interaction between farmers and buyers.
• Price Negotiation: Real-time price negotiation features embedded within the communication tool.
• Blockchain Integration: Built on blockchain technology for enhanced security and transparency.

Technologies Used

• Frontend: HTML, CSS, JavaScript
• Backend: Firebase (Authentication and Firestore)
• Blockchain: Ethereum, Solidity, ZetaChain
• Development Framework: Truffle for smart contract development and testing, Ganache CLI for local blockchain testing

Getting Started

Prerequisites

• Node.js and npm installed
• Truffle framework
• Ganache CLI installed (npm install -g ganache-cli)
• A Firebase project
• MetaMask wallet (for Ethereum transactions)

Installation

1. Clone the Repository:

   git clone https://github.com/your-username/kisansetu.git
   cd kisansetu

2. Install Dependencies:

   npm install

3. Start Ganache CLI:

   ganache-cli

4. Compile and Migrate Smart Contracts:

   Update truffle-config.cjs to use the local Ganache network:

   const HDWalletProvider = require('@truffle/hdwallet-provider');
   require('dotenv').config();
   
   module.exports = {
     networks: {
       development: {
         host: "127.0.0.1",
         port: 7545, // Default Ganache port
         network_id: "*", // Match any network id
       },
       zetachain: {
         provider: () => new HDWalletProvider(
           process.env.MNEMONIC,
           'https://zetachain-athens-evm.blockpi.network/v1/rpc/public'
         ),
         network_id: 7001,
         gas: 4500000,
         gasPrice: 10000000000,
       },
     },
     compilers: {
       solc: {
         version: "0.8.0"
       }
     }
   };

   (Also create a .env file with MNEMONIC="your-mnemonic-here")
   OR
   

   const HDWalletProvider = require('@truffle/hdwallet-provider');
   require('dotenv').config();
   
   module.exports = {
     networks: {
       development: {
         host: "127.0.0.1",
         port: 7545, // Default Ganache port
         network_id: "*", // Match any network id
       },
       zetachain: {
         provider: () => new HDWalletProvider(
           mnemonic, // Add your mnemonic here!
           'https://zetachain-athens-evm.blockpi.network/v1/rpc/public'
         ),
         network_id: 7001,
         gas: 4500000,
         gasPrice: 10000000000,
       },
     },
     compilers: {
       solc: {
         version: "0.8.0"
       }
     }
   };

5. Compile and Migrate the Smart Contracts:

   truffle compile --config truffle-config.cjs
   truffle migrate --config truffle-config.cjs --network zetachain

   (Parallely run ganache-cli and replace zetachain with development if deploying locally on Ganache.)

6. Start the Development Server:

   npm start

7. Access the Application:

   Open your browser and navigate to http://localhost:5000.

User Setup for MetaMask

To interact with the ZetaChain network on your platform, users need to configure MetaMask to include the ZetaChain network. Follow these steps:

Adding ZetaChain to MetaMask

1. Open MetaMask:

   • Click the MetaMask extension icon in your browser to open it.

2. Go to Settings:

   • Click the profile icon (your avatar) in the top-right corner of MetaMask.
   • From the dropdown menu, choose Settings.

3. Select Networks:

   • In the Settings menu, click on Networks. This is where you can manage and add custom networks.

4. Add a Network:

   • Click Add a network or Add a network manually. This will take you to a screen where you can add a custom network.

5. Enter ZetaChain Details: Fill out the form with the following details:

   • Network Name: ZetaChain
   • New RPC URL: https://zetachain-athens-evm.blockpi.network/v1/rpc/public
   • Chain ID: 7001
   • Currency Symbol: ZETA
   • Block Explorer URL: (Leave blank or use an explorer URL if available)

   Here’s what it looks like:

   Field	Value
   Network Name	ZetaChain
   New RPC URL	https://zetachain-athens-evm.blockpi.network/v1/rpc/public
   Chain ID	7001
   Currency Symbol	ZETA
   Block Explorer URL	(Optional) Leave blank or fill with explorer URL

6. Save:

   • After entering the details, click the Save button.

7. Switch to ZetaChain:
