Why Web3 Development?

Web3 is revolutionizing the Internet and how websites are made. Every web developer should learn Web3 to stay relevant. If you don’t learn Web3, you will get left behind.

JavaScript and React.js are fundamental to web development, so you will learn them in depth from scratch in this course. Then we’ll dive into dApp development with Web3.js.

With this course, you’ll not only learn how to code and become a web developer – but a dApp developer. This is a unique skill set that is in demand as more companies are using decentralized technology and incorporating blockchain, cryptocurrency, and Web3 into their websites and business processes.

What is Web3?

Web3.js is the #1 JavaScript library to interact with the Ethereum blockchain. Your website can include blockchain interactions, such as cryptocurrency transactions, passwordless sign-in with crypto wallets like MetaMask, interactions with Solidity smart contracts and SO MUCH MORE! 

With a Web3 website, your page visitors can use your site to send Ether, read and write data from smart contracts, create smart contracts, mint NFTs, trade tokens, and more.

Using Web3 is like reading and writing data from a web server, which is commonly used to sign up users to your site, update the number of products left in your database, and much more. But with Web3, you are interacting with the Ethereum blockchain as well.

What is React?

React is the #1 JavaScript library for building web user interfaces. Knowing a library like React is essential to getting hired as a web developer. With React, you can go from making simple websites to managing complex web apps with ease.

In this course, you’ll learn how to use React to build and manage your decentralized web apps.

What is JavaScript?

Javascript is one of the core technologies of the World Wide Web, along with HTML and CSS. With JavaScript, you can write web page behaviors like handling button presses, form inputs, and more. Developers commonly incorporate libraries like React.js and Web3.js to quickly add complex functionality to a web app.

Project 1 – Build a dApp with Truffle, Ganache, MetaMask, and vanilla JavaScript

Build a new blockchain project with Truffle, a popular decentralized app development tool. Launch a local Ethereum blockchain network with Ganache. Connect to cryptocurrency wallets from your website with MetaMask, a browser wallet extension. Handle crypto transactions and blockchain interactions via your website. All with Web3.js, Ethers.js, and vanilla JavaScript. This is the perfect project for a beginner web developer wanting to enter the Web3 space. This is your first of 5 capstone projects.

“I didn’t want to buy a course of just videos. I think having somebody to interact with, like you’ve been great both on Discord and chat… Then the class has been interactive but also you’ve hopped on a call and just helped me out which has been game changing. So that’s why I chose Lumiwealth, it was really because you guys offer that level of care.”

“There’s people coming from way different backgrounds, some people are day traders like me others are more in the field of finance, and so it was really cool to just meet everybody and interact.”

– Agim Salija

“The class has been great. It has done exactly what I sought out. I have learned techniques to help me assess the quality of trading strategies which I didn’t have before. Overall, it has boosted my ability to create a trading bot and more easily test strategies in a way that I wasn’t able to before.”

“For anyone who is looking to learn Python, Finance, and putting together the dots in order to create their own strategy or enter the job market, I think this would be a great course to take.”  

– Rene Serulle

“Absolutely would recommend the classes. I went live with this trading bot a couple of weeks ago and right now I have almost made 80% of the money I spent on the course itself back from the bot itself. The trading strategies that I learned in the class paid for the class itself. I don’t think there is a better return on investment.”

“Learning from you was one of the biggest advantages. The depth of your experience you have and sharing that with all of us is amazing. To have that kind of person who’s willing to teach other people and help them enhance their lives is amazing.” 

– Santayan Paul

“I liked the variety of things being covered the most during the classes, not only how to set up a bot and connect to a broker, but also CAGR, long-term economic data, and things that I wasn’t really thinking about. For example, how long term trends can affect short-term prices. I liked the overall breadth of the class and how it wasn’t just all about the algo trading portion of it; there was a lot of how and what too.”

“I would recommend Lumiwealth’s classes to anybody who wants to understand and take more control of their trading. To anyone who wants to learn about Python/technology and trading and how these two things interplay with each other.” 

– Joel Brass
