So you're upset you didn't sell the top? Don't worry, you won't sell the next one either. Or the one after that.

[Quit @0xQuit]

@yuge69 @nix_eth @RJFieldsofGold user says "I want to buy token for X"

price is lower than X.

jared buys token, sells it to user for X.

Jared makes a small profit, user pays the price they specified. They weren't robbed, just as they wouldn't have been stealing if the price moved in their favor.

I may be alone in this but jared did nothing wrong

[Quit @0xQuit]

@thatVEXEDguy mostly not an issue anymore since most wallets default to private transactions, not to mention protocols like cowswap and matcha are sandwich-free.

[Quit @0xQuit]

@nix_eth @RJFieldsofGold I think there's a big difference between skimming slippage (which users can just set lower btw) and engineering a trap to wipe out somebody's entire wallet.

[Quit @0xQuit]

@RealEnormous yes that I can agree with

[Quit @0xQuit]

@medicmatt203 two very different games

[Quit @0xQuit]

yes imo.

sandwich works because a person says "I'm willing to trade X of A for at least Y of B", and there's room to move the price to give them a worse (but still acceptable, as specified by the user) fill.

exploiting Jared used an elaborate scheme to commit theft.

not at all the same.

[Quit @0xQuit]

it's become abundantly clear that I need to specify which Jared

[Quit @0xQuit]

I may be alone in this but jared did nothing wrong

[Quit @0xQuit]

@adamsmoot nah that Jared can burn in hell

[Quit @0xQuit]

@thatVEXEDguy most people don't even notice they were sandwiched

[Quit @0xQuit]

@SH13LDS7 kind of...people are agreeing to a minimum output and if there's wiggle room between their minimum and the quote then Jared steps in to take advantage

[Quit @0xQuit]

@SH13LDS7 IANAL but imo grey area, illegal in traffic but in crypto it's acting on public info which seems fair to me

[Quit @0xQuit]

@jpgflippa yes to be clear Jared the pedo did LOTS wrong

[Quit @0xQuit]

@jpgflippa fuck 😭

[Quit @0xQuit]

@VonMaketh yup

[Quit @0xQuit]

@coffeedev we made cowswap, and private rpcs, and matcha, and FCFS L2s

[Quit @0xQuit]

@dumbnamenumbers @sterlingcrispin just a path Jared never thought of. Simple in retrospect but it's a very clever trap when you put the pieces together

[Quit @0xQuit]

If you've been in this space long enough, you have probably been sandwiched by jaredfromsubway.

No doubt you've heard of him.

Today, he was beaten at his own game to the tune of ~$14M.

@ethresearchbot HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA

....

HAHAHAHAHAHAHA.

fuck off.

@effereum_eth it may want the optionality to trade through uniswap forks, if the liquidity is there. I think the more appropriate check would be ensuring that approvals set during the bundle are cleared by the end.

[Quit @0xQuit]

4/ The attacker used this to their advantage, deploying over a hundred fake Uniswap V2-style pairs and fake ERC20 tokens. The pairs implemented the normal Uniswap pair interface and appeared to have deep liquidity, but the liquidity was in attacker-controlled fake wrapper tokens.

[Quit @0xQuit]

@effereum_eth they have to:
- look like a real pool
- offer Jared real profits on backruns
- not consume Jared's approvals in the process

it was just a really good bait and Jared took it
