Solidity is the most popular blockchain language in the world designed to build DApplications (Smart Contracts). It powers Ethereum and there is an in-demand exponential growth of high-paying jobs all over the world, which is changing the way we conduct business. The course starts with covering the Solidity fundamentals including variables, if/else, operators, Boolean logic, functions, arrays, modifiers, loops, strings, and more. You will also learn Solidity from scratch with topics such as public and private visibility, struct and Enums, special global and blockchain variables, suffixes, and addresses. You will also learn how Solidity works behind the scenes including the Ethereum Virtual Machine (EVM) and assembly, events and logging blockchain emissions, send versus transfer methods, scoping, and more. There will be a deep dive into functions such as modifier functions, cryptographic functions, fallback functions, and function overloading. Object-oriented programming will also be covered in depth along with advanced patterns. This knowledge will be applied to build an Auction DApplication as well as plug into the live main net and access the Ethereum Blockchain Data through real-world DApplications. Finally, you will learn Solidity techniques that are used by professionals in blockchain including test network deployment, IDE, debugging, and compiling. By the end of the course, you will have the knowledge and confidence that you need in order to ace your Solidity blockchain job interviews and become a professional developer for smart contracts and DApplications.

DApp (decentralized application) operates on a blockchain network. DApps are decentralized and rely on a distributed network of computers rather than a central server. They use smart contracts for automation and tokens for transactions and are open-source, promoting transparency. This course is designed to equip us with the essential skills and knowledge needed to become proficient in building decentralized applications (DApps) on the blockchain. Starting with an introduction to blockchain technology and decentralization, the course progresses through hands-on tutorials covering Solidity, the Ethereum blockchain, smart contracts, and front-end development using React. Students will learn to create, compile, and deploy smart contracts, build DApp user interfaces, and interact with the Ethereum blockchain. The course delves into advanced topics such as token creation, NFT marketplaces, and DeFi concepts. With practical exercises and projects like building a voting system, practical experience in DApp development, and optional sections on UI animation and React and state, learners will gain opportunities for further skill enhancement. By the end of this course, we will have a robust understanding of DApp development and the ability to build and deploy their DApp. The course imparts essential technical skills and emphasizes real-world project structuring, understanding DApp development, and preparing us for freelancing opportunities and blockchain careers.

For the past couple of years, there has been no bigger breakthrough in the IT world than Blockchain technology. The extremely fast growth of the industry, market, and the technology itself has led to an enormous shortage of programmers who truly understand the blockchain technology. Along with the latter, smart contracts have also emerged—and with them, Solidity. The aim of this course is to give you the easiest and the best route to becoming a blockchain developer. We will be focusing on smart contract development with Solidity in the Ethereum ecosystem. You will learn to create your first smart contracts in the Ethereum blockchain—even if you are a complete beginner and know nothing about programming or Solidity. The author will show you how to create your first smart contracts with Remix, the online IDE, and we will go through all the features that Solidity gives us as a programming language. You will also be able to set up your environment to start coding with Solidity on your local machine. The author will show you what settings and configurations he used to set up VSCode and how to successfully install Truffle on Windows. After that, he will teach you the basics of the Truffle Framework and how to make it work with Ganache as your own private Ethereum blockchain network. We will also test out our Solidity smart contract behavior by unit testing with Chai and Mocha. If you are a serious developer, you need to know that your code is working the way you expect it to. When you are finished, you will be able to create your own first decentralized application with Solidity and Truffle. While other courses are filled in with unnecessary information that makes them hard to navigate through and leave you confused, this course will take you step-by-step from a complete beginner to a master of Solidity and smart contract creation in the Ethereum ecosystem.

Ethereum blockchain development involves creating decentralized applications (DApps), smart contracts, and other digital assets on the Ethereum blockchain platform. Ethereum is a decentralized blockchain network known for supporting smart contracts, self-executing agreements with predefined rules that automatically execute. The course begins with an introduction and progresses to the Remix IDE, covering topics such as Blockchain basics and reading/writing smart contracts. It covers hands-on projects, the Blockchain Messenger, to explore Booleans, integers, and address types. The course progresses to Smart Money - Deposit and Withdrawals, diving into Metamask, Ethereum transactions, and the payable modifier. Smart Wallet takes us into Solidity mappings, structs, and low-level Solidity calls. Moving forward into ERC20 Token Sale projects, Web3.js, event handling, and modifiers lead to non-fungible tokens (NFTs) involving Truffle, smart contract debugging, and deployment. The course wraps up by exploring alternative development frameworks such as Hardhat and Foundry. Upon completing the course, we will be proficient in Solidity programming, smart contract development, and blockchain usage. We will have hands-on experience building real projects, including DApps and NFTs, and contribute to blockchain projects.
