Smart Contract Weakness Classification and Test Cases

A blog about blockchains and smart contracts development

Hey I'm Mark Muskardin, blockchain developer for Notional.Finance - a new DeFi application on Ethereum. I know how challenging it can be to learn Smart Contract programming with Solidity. Luckily, we have Ethernaut. A series of challenges that teach you Smart Contract security as you master Solidity. Get instant access to the private member's area of my FREE course "Smart Contract Security Fundamentals" by clicking here: https://security.6figureblockchaindeveloper.com/smart-contract-security-fundamentals You'll get step-by-step guidance on how to complete all of the Ethernaut challenges. And more importantly, you'll learn the top Smart Contract security hacks and attacks that you must know in order to become one of the world's first blockchain developers! Are you ready for the financial revolution? Let's go!

I’ve recently swapped out playing CTFs in my free time to trying to catch bugs in my free time, usually for a bounty. Since bug bounty platforms are usually focused on web or mobile applications, I thought it might be interesting to introduce an emerging branch of bug bounty, focusing on smart contracts.

This guide focuses on showcasing the architecture, roles and subtleties of most popular price oracles in Ethereum, ways to safely integrate them with defensive programming practices.

Price oracles are one of the most critical pieces of infrastructure in DeFi. They come in different flavors, and inevitably carry associated security risks. In this session we’ll cover the most popular price oracles available in Ethereum, along with the security considerations you must bear in mind when integrating them into your project. In this workshop, we will cover: The need for price oracles in DeFi. Architecture of popular price oracles in space. Security risks associated with each price oracle. Must-have and nice-to-have safe guards when integrating price oracles. Led by Martin Abbatemarco, Security Researcher, OpenZeppelin Read the guidelines here: https://blog.openzeppelin.com/secure-smart-contract-guidelines-the-dangers-of-price-oracles/
