Smart Contract Auditor Roadmap 2023 - Start a Smart Contract Auditing Career

Introduction

Becoming a proficient smart contract auditor requires a deep understanding of blockchain technology, web3, decentralized finance (DeFi), and programming languages like Solidity.

In this article, I will provide a complete roadmap for aspiring smart contract auditors in 2023. We will explore key areas of knowledge and suggest valuable resources to guide you through the learning process.

I have also prepared a comprehensive YouTube video that covers the same content in this article:

Smart Contract Auditing Fundamentals

To begin your journey as a smart contract auditor, it is essential to grasp the fundamentals of blockchain technology. Start by exploring the?Bitcoin Whitepaper, which outlines the core principles of blockchain and decentralized money.

Next, delve into the?Ethereum Whitepaper?to understand Ethereum’s role in enabling smart contracts and the web3 ecosystem. Additionally, familiarize yourself with the?concepts of web3 and its distinctions from web2, as well as the significance of?decentralized finance (DeFi)?in the smart contract space.

Several YouTube channels provide valuable insights and tutorials in this field. Consider exploring channels such as?JohnnyTime?(my own),?Finematics,?Whiteboard Crypto, and?Coin Bureau. These channels offer a wealth of knowledge to assist you in your learning journey.

Programming Foundations

Establishing a strong programming foundation is crucial before delving into smart contract auditing. Begin by learning?JavaScript, a widely-used language in web development. Online platforms like?Codecademy?and?FreeCodeCamp?offer interactive tutorials to help you grasp JavaScript effectively. Once you feel comfortable with JavaScript, you can transition to learning?Solidity, the programming language used for writing smart contracts.

Solidity — Mastering the Language

Solidity serves as the primary language for developing smart contracts on the Ethereum blockchain and other EVM chains. To master Solidity, consider utilizing resources such as?CryptoZombies. CryptoZombies provides an interactive game-based learning experience, guiding you through the intricacies of Solidity.

Begin by familiarizing yourself with the basic syntax, data types, and control structures of Solidity. Understand how to declare variables, define functions, and implement conditionals and loops. Online resources like the?Solidity documentation?and tutorials on platforms such as?Solidity by Example?can provide comprehensive guidance as well.

Smart Contract Development Frameworks

Familiarize yourself with popular frameworks like?Foundry,?Hardhat, and?Truffle, as they simplify smart contract development.

Learning Foundry

Foundry?is a powerful framework for smart contract development and auditing that deserves your attention as a smart contract auditor.

By familiarizing yourself with Foundry, you gain access to a range of features and tools that streamline the auditing process. Foundry offers comprehensive contract testing capabilities, allowing you to write and execute test cases to ensure the integrity and functionality of the contracts you’re auditing in Solidity language (unlike Hardhat, where you have to write tests in javascript).

To master Foundry, start by setting up a Foundry project and understanding its project structure. Learn how to compile, deploy, and interact with smart contracts using Foundry’s intuitive command-line interface. Dive into its?documentation?and explore practical examples and tutorials to gain hands-on experience.

By incorporating Foundry into your skill set, you expand your toolkit as a smart contract auditor.

Learning Hardhat

By mastering Hardhat, you will be well-equipped to audit smart contracts effectively.

Hardhat is a popular development environment and testing framework for Ethereum smart contracts. It provides a comprehensive set of tools and functionalities that streamline the development, testing, and deployment of smart contracts. Understanding Hardhat is essential because most of the code you’ll audit will be written in Solidity and deployed using the Hardhat framework.

Hardhat also offers a wide range of plugins that extend its capabilities. These plugins enable you to integrate additional tools, libraries, and services into your auditing workflow. For example, plugins like Etherscan, Solidity Coverage, and Gas Reporter can assist you in analyzing contract code, monitoring gas usage, and generating test coverage reports.

Exploring the?Hardhat documentation, tutorials, and practical examples will deepen your understanding of the framework.

Another great resource to master hardhat deepen you Solidity skills is the free 32 hours course by Patrick Collins:

By dedicating time and effort to mastering Solidity and becoming proficient in frameworks like Hardhat and Foundry, you establish a solid foundation for successful smart contract auditing. These skills enable you to comprehensively review and analyze Solidity code, effectively identify vulnerabilities, and provide valuable insights to enhance the security of smart contracts.

Smart Contract Hacking and Auditing

Now that you got the basics and the fundementals, it’s time to deep dive into smart contract hacking.?Practical experience?is crucial in becoming a competent smart contract auditor.

Completing a?comprehensive course in smart contract hacking?and auditing equips you with invaluable skills and positions you for auditing opportunities. Consider following a structured approach to learning that encompasses vulnerability exploits, proof-of-concepts, and secure coding practices.

The?Smart Contract Hacking course?offers over 30 chapters and 50 hands-on exercises, meticulously designed based on real-world scenarios, providing you with a systematic approach to learning and mastering the art of smart contract hacking.

Taught by industry-leading auditors, the course covers a wide range of concepts and practices, catering to both beginners and advanced learners. You’ll delve into topics such as flash loans, DAO and governance attacks, and Oracle manipulation. By completing the course, you’ll gain proficiency in identifying and creating proof-of-concepts (PoCs) for critical security flaws in smart contracts. This expertise will make you an invaluable asset to any blockchain project and will help you succeed in?Smart Contract Auditing Contests.

Beyond knowledge acquisition, the Smart Contract Hacking Course opens doors to potential auditor positions. Many students view this course as an opportunity not only to expand their skills but also to unlock the chance to secure an auditor role. Additionally, you’ll join a vibrant Discord community of like-minded specialists, fostering an environment for professional growth and collaboration.

Whether you’re looking to enhance your existing skills or embark on a journey toward becoming a proficient smart contract auditor, the Smart Contract Hacking Course provides the guidance, knowledge, and community support you need to excel in this evolving field.
