I love how AI also imports pandas, but then says "screw it, we'll do it with built-ins"

A brief thread on a novel MEV searching strategy, where we chase the trail of a mysterious bot backrunning private flow and reveal how they do it.

@andokura @SheaKetsdever 10 is all of the flags

@epheph @SheaKetsdever 10 is max? Or I can catch as many as I can?

@SheaKetsdever I’m hunting for CREATE2 flags for fun and captured 5-6 times, but didn’t see myself at leaderboard :( Maybe my submission are too hacky? :) goerli.etherscan.io/address/0xaAC2…

@andokura @SheaKetsdever After CTF, we will go over some of the solutions!

@epheph @SheaKetsdever Feeling I'm so late for that, so focused on CREATE2 salt/addr activates. So, no more time for magic number range :( Maybe share some code after that event / made an article?

@_harriscole That doesn’t seem like a realistic explanation, ok dm details

@epheph hey scott, a bad swap on uniswap's protocol resulted in a loss of funds and was hoping you may be able to offer guidance or insight on what happened or if i have any ways of recovering

@_harriscole So there was an error in the UI? How did it happen ?

@epheph a legitimate swap on the correct protocol resulted in a direct transfer to the universal router (calldata was somehow omitted from the transaction) - can send over full breakdown of the events in details with txns over DM

@MevRefund @Uniswap Checking the 3000 vs 500 fee pools?

@epheph @Uniswap Don't think so, checked top of block and a few before that, the ETH->USDC->ETH leg was never profitable ¯\_(ツ)_/¯

@Uniswap what you doing here? Poor man just wants to plow 0.36 Eth into some shitcoin. Router seems to have added some pointless trades, taking 0.36 -> 0.359 before finally allowing the man his poor life choices. Gotta help out those LPers, I guess? etherscan.io/tx/0xd930fea64…

I’ve been beating this drum ever since this feature was rolled out — it is structurally unsafe to sign an opaque hash representing arbitrary listings The @blur_io marketplace is upgradeable — it is imperative that they move to signing readable, typed data like Seaport does ASAP
