Cairo Security Unlocked: A Guide to the Modules
This article will walk you through the key modules designed to help you secure your Cairo and Starknet projects. Whether you're a developer, auditor, or just curious about zero-knowledge (ZK) systems, this guide is for you.
You can find all of the modules on our foundation.extropy.io site.
Module 1: Introduction to Cairo Security
In this module, we kick off with an introduction to the security challenges and best practices for ZK protocols. You'll learn about common vulnerabilities and how to effectively audit ZK systems.
Module 2: Exploring the Cairo Language
Here, we dive into the Cairo language, covering key features like Ownership, Structs, Traits, and Matching. We also compare Cairo with Solidity to help you transition smoothly between these two languages.
Module 3: Starknet Architecture
This module breaks down the architecture of Starknet, Ethereum’s Layer 2 solution. We cover Starknet’s essential components and how they interact with Ethereum’s Layer 1, which is crucial for building scalable dApps.
Module 4: Cairo Contract Structure
Learn the foundational structure of Cairo contracts, including storage management and advanced features with OpenZeppelin. We also cover best practices for interacting with other contracts and essential build tools.
Module 5: Auditing Cairo Smart Contracts
In this module, we focus on the auditing process for Cairo contracts, identifying and mitigating vulnerabilities. We also explore the critical aspects of Layer 1 to Layer 2 interoperability to ensure your contracts are secure across different blockchain layers.

Module 6: Essential Tools for Cairo Development
We provide an overview of the essential tools for Cairo development and auditing. From development environments to specialized auditing tools, this module equips you with the resources necessary to enhance your Starknet applications' security.
Module 7: Critical Testing Techniques
This module covers the key testing techniques every Cairo auditor should master, including unit tests, fuzz testing, and fork testing. You’ll learn how to thoroughly test your contracts before deployment.
Module 8: Smart Contract Auditing Principles
Here, we expand our focus to cover the general principles and methodologies of smart contract auditing. You’ll gain insights into the audit process, categorizing vulnerabilities, and estimating audit costs.
Module 9: Real-World Audit Reports & Vulnerabilities
In the final module, we analyze real-world audit reports to uncover common vulnerabilities, such as lack of access control, inconsistent storage updates, reentrancy, and sandwich attacks. Learn how to mitigate these effectively.
