We retrieved every contract on Ethereum. Along the way, we found the exact date when 16,000 unique contracts were deployed (the most in one day), the EOA with the most deployed contracts (2.9M), and much more. This is how we did it.🧵 (Spoiler: It’s 69,788,231 contracts!)

After days and eventually weeks after discovering the contract and having it remain unexploited, I just kind of hoped that since it hadn't been exploited today, it wouldn't be exploited tomorrow. 🧵(14/15)

The lesson learnt here is to move fast on the blockchain - otherwise someone is bound to move faster, and take the pot for themselves. 🧵(15/15) END
