Building Web3 Dapps with React: A Practical Guide

As the next generation of the web (Web3) continues to emerge, decentralized apps (Dapps) are becoming increasingly popular. Dapps can natively interact with blockchain technologies and unlock endless possibilities for innovation. In this workshop, we will explore the core concepts of Web3 and learn how to build a full-stack Ethereum React application from scratch. We'll cover the fundamentals of building Dapps, including interacting with Ethereum smart contracts, managing transactions, and handling events. By the end of the workshop, attendees will have a solid understanding of how to build and deploy a fully-functional Web3 Dapp using React, as well as an understanding of the unique challenges and considerations that come with developing decentralized applications.
