Security

This is an excerpt from the upcoming Assembly, Opcodes, and Formal Verification course. We go over the following in this video: - How to write a smart contract in Opcodes (with Huff!) - How to disassemble a smart contract - How to read the bytecode of a smart contact (without it even being verified on Etherscan!) - How to write Yul/Inline assembly in Solidity - How to truly become a gas optimization professional using low-level programming languages - How the Opcodes in the EVM work GitHub repo associated with this video: https://github.com/Cyfrin/1-horse-store-s23 GitHub Repo for the coming course: https://github.com/Cyfrin/assembly-evm-opcodes-and-formal-verification-course Security Course on Updraft: https://updraft.cyfrin.io/courses/security Register for Cyfrin Updraft: https://updraft.cyfrin.io/ ⏰ Timestamps ⏰ 0:00:00 | Introduction 0:02:57 | Horse Store - Huff & Opcodes 2:07:39 | Breaking down solidity compiled opcodes 3:24:47 | Yul 3:48:40 | HorseStoreV2 - Huff 4:28:30 | Gas Comparisons & Summary 😸😸Follow Patrick!😸😸 Cyfrin: https://www.cyfrin.io/ YouTube: https://www.youtube.com/@PatrickAlphaC/videos Twitter: https://twitter.com/patrickalphac Medium: https://medium.com/@patrickalphac TikTok: https://www.tiktok.com/@patrickalphac 🛡️ More Cyfrin CodeHawks: https://codehawks.com/ Solodit: https://solodit.xyz/ Updraft: https://updraft.cyfrin.io/ All thoughts and opinions are my own.

On the 30th of July, 2023, multiple Curve.Fi liquidity pools were exploited as a result of a latent vulnerability in the Vyper compiler, specifically in versions 0.2.15, 0.2.16, and 0.3.0. While bug was identified and patched by the v0.3.1 release, the impact to protocols using the vulnerable compilers was not realized at the time and they were not explicitly notified. The vulnerability itself was an improperly implemented re-entrancy guard that could be bypassed under certain conditions which we will delve into in this report.

“Watchdog analyses operate on the actual bytecode of contracts (via decompilation as seen here) As a result, compiler bugs can also be caught by these analyses Yesterday's @CurveFinance hack could have been prevented had a cross-reentrancy analysis on this codebase been run”
