In this course, you’ll learn to build smart contracts and Web3 apps using Solidity, Hardhat, React, Next.js, and Tailwind. Web3 apps leverage blockchain and smart contracts to enable transparent interactions, making them ideal for industries like finance, supply chain, gaming, etc.

You’ll learn to initialize and run contracts, define terms and conditions within code, and pass and store values inside contracts. You’ll explore additional functionalities like requiring valid arguments, receiving and sending payments, and ensuring balance constraints. By the end of the course, you’ll finalize the run script and successfully execute smart contracts. You’ll also experience building the frontend using React and related technologies, and learn about the front-end tech stack for Web3 applications.

This course will empower you to become proficient in Web3 app development, enabling you to contribute to the growing decentralized ecosystem and take advantage of the exciting opportunities blockchain technology presents.
