Fullstack DApp 2025: Solidity, React & Ethereum Blockchain

In this comprehensive course, you will learn to build a full-stack Web 3.0 application from scratch. We’ll begin by creating a Solidity smart contract, the leading language for Ethereum and EVM-compatible blockchains. You will then compile and deploy this contract on a local node using Hardhat, a powerful development framework for Ethereum.

Next, we’ll dive into Layer 2 (L2) solutions, exploring how to deploy smart contracts on zkSync, a cutting-edge technology that enhances scalability and reduces transaction costs on Ethereum.

You’ll also learn how to integrate decentralized storage with IPFS (InterPlanetary File System), using Piñata as the IPFS provider to store your data in a decentralized manner.

Furthermore, we will cover the integration of blockchain oracles with Chainlink, enabling your smart contracts to fetch real-time data, such as price feeds, directly from the outside world.

By the end of this course, you will have a solid understanding of building, deploying, and integrating full-stack Web 3.0 applications. This includes setting up a local environment and deploying to a live blockchain. Whether you're a beginner or an intermediate developer, this course will equip you with the essential skills to build scalable and robust blockchain applications.

In addition, you will learn to develop the frontend with React, creating a seamless user interface for your Web 3.0 application. We will also integrate a funding feature on top of the polling functionality, allowing you to understand and implement funding mechanisms within blockchain apps.
