![]() ![]() The hardhat config in where we define our hardhat network:.It’s easy to understand for newcomers because it’s just JavaScript - or TypeScript in our case. We will be using hardhat because it has nice features, is fast, and allows forking the Ethereum mainnet right before the hack occurred. All future posts in this series can be found on my blog in the replaying-eth category.įor the remainder of this introductory post, let’s set up our environment. I’ll try to keep a balance between analyzing interesting historical hacks and fresh exploits. Information on hacks is usually scattered among many different blog posts and tweets, and creating a list of exploits in a more or less standard format (description, block number, exploit code) of this piece of decentralized internet history is oddly satisfying. I’ll try to give the intuition first, followed by a technical deep-dive into the vulnerable protocol code, closing with writing code to replay the exploit on a local network. There are still many hacks that I don’t correctly understand even after reading the post mortems. (I’m not blaming the project parties for this, usually, these reports are written under time pressure because the users and investors want updates as fast as possible, but thoroughly researching the hack takes time.) Truth is, they often don’t convey any intuition on what the heart of the issue was and how to prevent it. They simply rehash the transaction call stack in a human-readable form: “Attacker takes a $X flash loan, swaps $X for $Y, deposits $Y into protocol Z, …“. Many existing post mortems are very vague and pseudo-technical.In addition, I found that practically solving a problem (instead of just reading about it) is the best way to make information stick. Deconstructing the attacks to be able to implement them from scratch makes sure that we really understand what’s going on.Looking at real-world exploits is the best way to learn about attack vectors that are actually used and therefore it’s also a great way to learn how to protect against them in the future.To learn about smart contract security.This is a valid objection, but I still think it’s very valuable for these reasons: One might ask themselves what the benefits of doing this might be - especially as the hacks are already documented through post mortems.
