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!)

2023 - 3rd place 🥉 2024 - 2nd place 🥈 and finally, 2025 - 1st place 🥇!! by a VERY small margin of just 50 points! (please consult the graph) this is the closest amount ive ever experienced, and it was even more nerve wracking as the scoreboard was frozen for the last hour.

The curse has been broken! 🏆We finally won BSides Canberra CTF 2025!🥇 Congratulations to our close competition @FrenchRoomba and SoberOstrich. Thanks to @BSidesCbr for the outstanding conference, and of course @sk8boardingdog 🛹🐶 for the amazing CTF this year.

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 🧵👇
