We had a great time at @CODEGATE_KR CTF finals this year as 🤬🇫🇷🛹🐻! Thanks to the organisers for the challenges, we had a great time. Hope to see everyone next year 🇰🇷
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!)

Zellic proudly announces the EVM trackooor, a modular tool for monitoring arbitrary actions on chain. With the amount of data that blockchains contain, it’s difficult to query and process anything that isn’t indexed event fields. This is why we built EVM trackooor 🧵👇
