In the rapidly evolving world of blockchain technology, mastering Solidity is crucial for developing secure and efficient smart contracts. This advanced course takes you beyond the basics, guiding you through complex Solidity concepts and the intricacies of secure contract development. Each module is meticulously designed to deepen your understanding of Solidity, from recognizing common vulnerabilities to implementing robust security measures. The course begins with essential advice on approaching new Solidity concepts, gradually leading you through advanced topics such as looping and transactions, points of failure in contracts, and the significance of safe contract design. You'll explore critical issues like whether contracts should be allowed to receive funds and how to protect them from common exploits. Through a combination of theoretical insights and practical exercises, you will learn to recognize, analyze, and mitigate security risks in smart contracts. As you progress, you’ll engage with hands-on coding exercises that solidify your learning, including creating and securing smart contracts, understanding complex patterns like the "Only After" modifier, and mastering advanced concepts such as inheritance and abstract contracts. By the end of this course, you’ll not only be proficient in Solidity but also equipped with the skills to develop secure, high-performing blockchain applications. This course is tailored for experienced developers familiar with basic Solidity concepts who are looking to advance their skills in secure smart contract development. Prerequisites include a solid understanding of fundamental Solidity, blockchain principles, and some experience with writing and deploying smart contracts.

Syllabus

Solidity Patterns I - Cybersecurity

In this module, we will dive deep into the cybersecurity aspects of Solidity smart contract development. You will learn about common vulnerabilities, how they can be exploited, and the best practices to secure your contracts. We will also explore advanced Solidity patterns and challenge your knowledge through quizzes and exercises.

Solidity Patterns II - Restricted Access

In this module, we will dive deeper into the Restricted Access pattern in Solidity, focusing on how to control access to smart contract functions. We'll cover key modifiers, such as onlyOwner and time-based restrictions, and provide hands-on exercises to reinforce these concepts.

Learn Advanced Solidity I (Inheritance and Abstractions)

In this module, we will dive deep into advanced Solidity concepts, including contract visibility, inheritance, and abstraction. Through a series of explanations and hands-on exercises, you’ll explore how to structure and organize contracts effectively, work with visibility modifiers, and implement inheritance to improve the scalability and efficiency of your decentralized applications.

Learn Advanced Solidity II

In this module, we will explore advanced concepts of Solidity, including interfaces, libraries, and low-level programming with Assembly. You'll also dive deep into error handling and security best practices, while building complex decentralized applications like an auction DApp. The section emphasizes practical exercises to ensure you master the topics thoroughly.
