Security Course 101

The course’s objective is to. Understand how to make a smart contract. . We need to keep in mind not only what we want to create in the contract, but how to generate security-focused code.

Since the contracts in a large percentage represent real money, we need to be updated as developers on the most. There are known vulnerabilities. And know. How old hacks worked. Don’t repeat those same errors.

The most known vulnerabilities are the focus of this course. Good practices and explanations of problems. Conflicts can arise when using upgradeable contracts or how to get random numbers.

Not only will this knowledge help to develop smart contracts, it will also help to audit them. It is a core knowledge of smart contracts.

What will you learn in this course?

In this course you will learn:

Understanding security in a Blockchain Application.
How does an attack on a Smart Contract work?
Known attacks and how to fix them (Reentrancy, Overflow, Replay Attack, DoS, weak randomness, and much more).
