Smart Contract Security 201
Learn skills needed to audit smart contract code

Security Course 201

This is the second course in our Smart Contract Security curriculum.

One of the most pressing problems for smart contract deployment is security and as such it is paramount we understand how to develop a smart contract in the safest way possible. But going one step further, this is not enough. We need to be able to audit our own smart contract code using various automated tools and also manual revisions.

Since the large percentage of the contracts represent real money, we, as developers need to be on top of everything and should always be up-to-date on the most known vulnerabilities and know how old hacks worked so as not to repeat those same errors within our own smart contracts.

There are both pros and cons to using the automated analysis tools and/or auditing the code manually for any vulnerabilities. It is good practice to also optimize for gas so users don’t end up paying too much when interacting with our smart contracts.

Lastly, the course goes through the various stages of a professional audit and what it entails and by the end of it will make you an expert on how to apply the same knowledge in evaluating your own smart contract code.

In this course, you will learn:

• Introduction to Audits
• Understanding security in a Blockchain Application
• How does an attack on a Smart Contract work?
• Best practices and security patterns
• Manual Audits and using tests to audit the code
• Automated Analysis Tools vs Manual revisions
• Gas Optimization and tools to measure gas costs
• Review of Public Audits
• Stages of a Professional Audit

We will use:

• Hardhat
• Solidity
• Slither

Prerequisites:

• Solidity Basics:
  Solidity Types
  Function Declarations
  Modifiers
  How Inheritance works
• Blockchain Basics:
  Gas fees, Gas limits
  EOA vs Contracts
  Transactions vs Calls
• Hardhat Basics:
  How to deploy and interact with a smart contract
  Basic Testing
  Hardhat Configuration
