Introduction0:35

Setting up Remix IDE0:12
Remix + JavaScript VM4:28
1️⃣ Open Remix IDE (https://remix.ethereum.org)
2️⃣ Compile the smart contract in the Solidity Compiler tab.
3️⃣ Go to the Deploy & run transactions tab and in the Environment dropdown select JavaScript VM.
4️⃣ Click Deploy - your smart contract should be deployed in the Deployed Contracts section.
Remix + Metamask0:37
Remix + Hardhat0:25
Working in Remix3:46
Setting up VS Code4:06
Setup update1:49

Bool, numbers and strings1:53
Boolean data type1:33
Integers9:59
Explore solidity integers, including unsigned and signed types, their eight-to-256 bit dimensions, and overflow handling with unchecked blocks.
Strings2:42
Constant2:59
Number operations0:51
Dimension limits1:55
Immutable type5:08
Learn how constants require immediate assignment and how immutable variables are set in the constructor and cannot be changed, then compare gas costs and ownership enforcement using require.
Bytes13:08
Data types

Mapping1:51
Mapping3:39
Arrays1:38
Working with Arrays1:24
Arrays6:00
Explore fixed-length solidity arrays, declare ten elements, and index from zero to nine. Learn reading and writing values, default zeros, and nested arrays with outer length three and inner ten.
Enums (Enumeration types)0:54
Enum2:24
Struct2:03
Struct4:55
Define a solidity struct with sender address and amount, and store it in a dynamic public array called payments. Access fields with dot notation to read values.
Reference types13:37
Composite data type

Functions, transactions and calls1:40
Functions6:05
Visibility4:58
Examine the four visibility scopes, public, private, internal, and external. Public functions are callable externally; private functions stay internal; internal supports inheritance; external functions are callable only from outside.
Data Storage4:45
Functions: View, Pure and Payable1:30
View, Pure and Payable14:58
Explore view, pure, and payable modifiers in Solidity, distinguishing read-only calls from state-changing transactions, understanding gas costs, return behavior, and how payable functions receive funds.

Description

Welcome to the ultimate Solidity programming course, meticulously designed for beginners eager to embark on a transformative journey into the world of blockchain and smart contract development. With 104 professionally produced videos, this course takes you from the very basics to advanced Solidity concepts, ensuring you become proficient in writing, deploying, and managing smart contracts on platforms like Ethereum and Polygon.

Learn how to write smart contracts in the latest version of Solidity, use the OpenZeppelin library and Hardhat tools, optimize gas, and grok EVM bytecode. We'll get you placed in a global crypto project upon successful completion, unless you're headhunted midway.

One of the unique facets of this course is its emphasis on hands-on experience. You'll be immersed in a series of practical projects, allowing you to develop real-world DApps, including e-shops and digital wallets. These projects not only fortify your understanding of Solidity but also provide a solid portfolio foundation, showcasing your skills to future employers or clients.

To ensure a comprehensive grasp of the subject, we've incorporated a series of quiz assignments. These quizzes test your knowledge, reinforce your learning, and highlight areas that might need further attention.

Smart contract security is paramount. Hence, a significant portion of the course delves into testing and vulnerability assessment of smart contracts. You'll be trained to identify, mitigate, and prevent potential threats, ensuring the contracts you write are not just functional but also secure.

Lastly, to enhance your development environment, we will explore powerful tools and plugins such as Hardhat and Alchemy. These tools streamline the development process, offering features like local blockchain emulation, advanced debugging, and more.

By the end of this course, you'll be well-equipped with the knowledge and tools necessary to confidently navigate the dynamic world of smart contracts and DApp development. Join us on this exciting journey and unlock the vast potentials of blockchain technology.
