Solidity & Ethereum in React (Next JS): The Complete Guide

Spread the love

Solidity & Ethereum in React (Next JS): The Complete Guide. Developing blockchain applications can be hard. The Solidity programming language is relatively new, the Ethereum blockchain itself is still maturing, and the ecosystem of supporting libraries and frameworks is evolving rapidly. Writing smart contracts can be especially challenging for non-developers, who sometimes struggle to grasp the difference between Solidity’s “code” and its “state”. This course breaks down Solidity by showing you how it maps to JavaScript (the language of the web). It specifically focuses on the React framework for app development, making these core concepts applicable to real-world decentralized applications (DApps).

What you’ll learn in Solidity & Ethereum in React (Next JS): The Complete Guide

  1. On the blockchain, make real-world apps.
  2. With ease, create smart contracts and DApps.
  3. Learn about Ethereum in a practical and enjoyable manner.
  4. To work with any blockhain, you’ll need a comprehensive toolkit.


  • React JS is a must-have.
  • It’s preferable, but not necessary, to know HTML and CSS.
  • Willingness to pick up new concepts, even if they appear difficult at first.

Solidity & Ethereum in React (Next JS): The Complete Guide

What is Ethereum and what does it stand for?
Ethereum is a technology that allows you to send cryptocurrency to anyone, but it’s also the world’s programmable blockchain, which means it can power applications that anyone can use and that no one can takedown.

Both allow you to use digital money without the use of payment providers or banks; however, because Ethereum is programmable, you can use it for a wide range of digital assets, including Bitcoin.
This means Ethereum is more than just a payment system; it’s also a marketplace for financial services, games, and apps that can’t steal your data or censor you. It’s the Future.

Smart contracts are programs that govern the behavior of accounts within the Ethereum state. Solidity is an object-oriented, high-level language for implementing smart contracts.
Solidity is a curly-bracket language inspired by C, Python, and JavaScript and designed to run on the Ethereum Virtual Machine (EVM). The language influences section contains more information about which languages Solidity was inspired by.

You can use Solidity to build contracts for voting, crowdfunding, blind auctions, and multi-signature wallets, among other things.
What will you learn in this class?
The course will teach you everything you need to know to become a blockchain developer, including what Ethereum is and how it works at a fundamental level and from the perspective of a developer.

React library and Next JS framework were used to build the frontend for the dApps covered in the course, while Bulma and Tailwind frameworks were used to build CSS and design.
The course includes the development of two real-world applications, with each step of the process thoroughly explained and documented.

Students will learn the fundamentals and core knowledge of the Ethereum network by working on practical applications in this first application of the course.
The application’s front end was created using the React library and the Bulma framework, while the smart contracts were created using the Truffle development environment and Ganache (private blockchain).

The first application’s goal is to go over the fundamentals while having fun working on something useful.
The following are the most important questions that this app addresses:
Application for the market:
Clients of this application will purchase courses (students can choose products of their choice) with Ether digital currency, according to this application.

The second application includes a plethora of features, such as a marketplace page that displays real-time Ether currency and course prices in comparison to the US dollar.
The modal window is dedicated to placing orders. It includes an email hashing solution to protect the privacy of clients, an order view with order filtering and pagination, and many other features.

SSR has numerous advantages, but it also has a number of issues when it comes to blockchain integration.
The entire Next JS blockchain integration part is covered, well explained, and documented, and the final application will be deployed on the internet, with the smart contract deployed to the “live” mainet network.

Who this course is for:

  • Beginners as well as experienced devs interested in blockchain tech.
  • People looking for the practical Solidity/Ethereum/NextJS development guide.
  • This course is for everyone eager to understand how to build an app from scratch
