Course Description
Blockchains and technologies supported by blockchains such as distributed apps (dApps/smart contracts), NFTs, and Web3 are taking the world by storm. Everyone is talking about them and developers knowledgeable in these technologies are some of the highest-paid in the world!
The trouble is that, if not learned properly, there are so many components to a dApp that you can easily get lost in the hundreds of components, libraries, and tools floating around the web. Even the official documentations are not sufficient since they only discuss one tool/library at a time and miss out on the integration of everything to create a working dApp.
To top off the issue, all existing courses on the topic try to explain everything in detail and in doing so, cause even more confusion. This is not the right way to approach the domain. As the official documentation of solidity (the official smart contract language of Ethereum) puts it, "do you have to know how Amazon's AWS works internally in order to use it?". The answer is, obviously, no!
Similarly, to learn how to create dApps, you can assume that a blockchain is a distributed data store that provides certain guarantees. Then, start using existing blockchain frameworks to deploy your dApps just as you would deploy your sites on the web without having to rebuild a webserver!
This is the approach we take in this course. We will set up a blockchain environment using stable, easy-to-use frameworks. Then, we will look at two smart contracts (or dApps) and deploy them first locally and later on a global distributed testnet. This will take you through all the steps needed to deploy your own dApp with minimal effort. In the end, you will be in a position to deploy your (and your clients') dApps on the Ethereum mainnet.
This is supposed to be the first step in your journey towards dApp. This is not a comprehensive guide to all smart contract tools or even an in-depth discussion about a particular tool. Take this first step and the rest of the stuff will be much, much easier for you.
Finally, I provide exceptional support for all my courses. All questions are answered within 24 hours. Plus, if you don't like the contents, I absolutely do not mind if you take advantage of the 30-day money-back guarantee!
Join me now and let's get cracking on that dApp!

Great hands-on courses for beginners
All my courses are 100% hands-on with practical examples and demos. No lengthy theoretical discussions about boring topics. We dive into the practical and only see theory if needed (and only the minimum amount).
Learn by doing
Step-by-step tutorials and problem-based learning.
Get excellent support
One-on-one support by me ... All questions answered within 24 hours. I really want you to succeed!

Great course. I would like to see a part II or supplementary course for this one.

hardhat、solidity,reactを利用したDapp開発のための基礎力を身につけることができました。公式サイトのチュートリアルを読むことも大切ですが、やはり画面共有しながら実装を進めていくので大変分かりやすかったです!

NOT Justifiable to be a paid course. NOT much explained
By Shadman Wakil on 3/6/2022
A little more info for How to install node could be helpful. I had some older version node installed that was creating some issues. I removed the node, npm and nvm completely from my system(including their configuration file) and installed from website shown in the tutorial. And then it's start working fine.

Very good and simple, allows you to start with some complexity without getting lost. Very good if bought for 10 euros
By Sabarinathan thangaraj on 12/30/2021
Excellent course from developer point of view. Want him to do another course covering full stack, include testing for the app.
By Nauman Afsar on 11/26/2021
Been on Udemy for years and this is the first course that I actually finished, says a lot about this course.

Everything is smooth and to the point. As a beginner in learning about DApps this course have helped me a lot in clearly basic concepts.
By Shuraih saljoqi on 10/24/2021
Excellent course, if you are confused on how to get started with DApps then this is a great course to start with.
By Muhammad Irfan Shahzad on 10/24/2021
Really helpful course, It's a opportunity for learning somethings new and interesting. course are well design and easy to understand.
