Project Description
In this project, we’ll develop a chat application that integrates with the Ethereum blockchain using React and Hardhat. This application provides a seamless and secure platform for users to communicate with each other while utilizing the advantages of blockchain technology.
We’ll begin by writing the smart contract using Solidity and using Hardhat to deploy and test the contract. This contract will serve as the foundation of our chat application, handling all communication logic. It ensures secure and transparent interactions in our blockchain-based chat environment. Then, we’ll deploy it on a local Ethereum Hardhat node for testing. Lastly, we’ll use React to build the frontend of the application. We’ll be creating an interface where multiple users will be able to communicate via the chat application in real time.
