KryptNetwok

Overview

KryptNetwok is a decentralized application (DApp) that enables users to transfer Ethereum securely from one MetaMask wallet to another. Leveraging React for the frontend and Ethereum smart contracts for the backend, KryptNetwok ensures transparent and reliable transactions on the blockchain.

Features

• Secure Transfers: Safely send Ethereum between MetaMask wallets using smart contracts.
• User-Friendly Interface: Intuitive React-based UI for easy wallet connection and transaction handling.
• Transaction History: View all past transactions with detailed information.
• Real-time Feedback: Receive instant updates on transaction status.

Technologies Used

• Frontend: React, Tailwind CSS
• Blockchain: Ethereum, Ethers.js
• Smart Contracts: Solidity, Hardhat
• APIs: Giphy API for enhancing UI with GIFs based on transaction keywords

Getting Started

Prerequisites

• Node.js installed on your machine.
• MetaMask extension installed in your browser.
• An Ethereum wallet with some test ETH on the Sepolia network.

Installation

1. Clone the Repository

   git clone https://github.com/yourusername/kryptnetwok.git
   cd kryptnetwok/client

2. Install Dependencies

   npm install

3. Configure Environment Variables

   Create a .env file in the client directory and add your Giphy API key:

   VITE_GIPHY_API=your_giphy_api_key

4. Start the Application

   npm run dev

   The application will be running at http://localhost:5173 by default.

Smart Contract Setup

1. Navigate to the Smart Contract Directory

   cd ../smart_contract

2. Install Dependencies

   npm install

3. Deploy Contracts

   The smart contract is deployed on alchemy so create a wallet project on alchemy and paste the Alchemy api key in hardhat.config.js Also generate the private key in your MetaMask account The below command will deploy your smart contract to alchemy

   npx hardhat ignition deploy ./ignition/modules/Token.js --network sepolia

4. Update Frontend Constants

   After deployment, update the contractAddress and contractABI in /client/src/utils/constants.js with the deployed contract details.

Usage

1. Connect Wallet

   Open the application and click on the "Connect Wallet" button to link your MetaMask account.

2. Transfer Ethereum

   Fill in the recipient's address, the amount of ETH to send, a keyword for the GIF, and an optional message. Click "Send now" to execute the transaction.

3. View Transactions

   All transactions will appear in the "Latest Transactions" section, complete with details and related GIFs.
