Table of Contents

Introduction

Welcome to the Ethereum Calculator DApp! This decentralized application operates on the Ethereum test network, powered by Ganache as the local blockchain. With a user-friendly interface built on React.js, our calculator DApp allows you to perform basic arithmetic operations securely on the blockchain.

Features

  • Decentralized Arithmetic: Perform addition, multiplication, division, and subtraction on the Ethereum test network.
  • Local Blockchain (Ganache): Utilize Ganache as the local blockchain for development and testing purposes.
  • Web3.js Integration: Seamlessly connect the frontend with the Ethereum blockchain using Web3.js.
  • Smart Contract (Solidity): The calculator functionality is implemented as a smart contract using Solidity.
  • User-Friendly Interface: Enjoy a clean and intuitive interface for a seamless user experience.

Technologies Used

  • Ethereum Blockchain: For secure and transparent arithmetic operations.
  • React.js: For a user-friendly and interactive front-end experience.
  • Web3.js: To interact with the Ethereum blockchain and smart contracts.
  • Solidity: For developing the smart contract that handles arithmetic operations.
  • Ganache: For running the local blockchain during development and testing.

Apologies for the oversight. Here's the updated section for deploying the smart contract using Remix:

Getting Started

Follow the steps below to set up and use the Ethereum Calculator DApp on your local machine.

Prerequisites

  • Node.js and npm installed on your system.

Installation

  1. Clone this repository to your local machine:
git clone https://github.com/saishmirajkar/Decentralised-calculator-.git
  1. Navigate to the project directory:
cd Decentralised-calculator-
  1. Install the required dependencies:
npm install
  1. Navigate to the project directory:
cd my-app
  1. Install the required dependencies:
npm install

How to Use

  1. Deploy the smart contract using Remix:

    • Open Remix IDE.
    • Copy the smart contract code from smart-contract/Calculator.sol.
    • Deploy the contract on the Ethereum test network (e.g., Ropsten) through Remix.

  2. Update the contract address in src/App.js:

    • Replace the contractAddress variable value with the deployed smart contract address.

  3. Launch the application on your local server:

npm start
  1. Open your web browser and navigate to http://localhost:3000.
  2. Perform arithmetic operations using the Ethereum Calculator DApp.
