Description
In this course, you will learn how to create a full-stack Web 3.0 application from scratch. We will start by writing a smart contract using Solidity, the leading language for Ethereum and EVM-compatible blockchains. Next, we will compile and deploy the smart contract on a local node using Hardhat, a powerful development environment.You will then explore deploying smart contracts on an L2 (Layer 2) network using zkSync, a cutting-edge technology that enhances scalability and reduces transaction costs. Beyond deployment, the course will guide you in integrating Web 3.0 applications with decentralized storage solutions like IPFS (InterPlanetary File System) using Piñata as the IPFS provider.Finally, we will cover how to integrate blockchain oracles with Chainlink to fetch real-time price feeds and other off-chain data directly into your smart contracts.By the end of this course, you will have a thorough understanding of creating, deploying, and integrating full-stack Web 3.0 applications on a Local setup. Whether you’re a beginner or an intermediate developer, this course will equip you with the skills needed to build robust and scalable blockchain applications.In addition, the course includes developing the frontend with React, providing a seamless user interface for your Web 3.0 application. We have also integrated “fundme” functionality on top of the polling functionality to support and learn funding mechanisms effectively.
