Course Description

This is the second course in our Smart Contract Security curriculum. You can check out the first course at https://pro.eattheblocks.com/p/smart-contract-security-101 which covered different vulnerabilities such as overflow and underflow, reentrancy and denial of service attacks while this second course is designed to go one step further by focusing on the aftermath of smart contract development, most specifically with regards to audits.

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.
