Wallets tied to Jaredfromsubway.eth, one of Ethereum's most active MEV bots, bought 2,063 ETH for about $3.94 million at $1,912 per token four days ago, then sold 2,167 ETH for roughly $4.05 million at $1,872 per token today — buying higher and selling lower, according to on-chain tracking by Lookonchain.
The irony is notable given the bot's reputation. Jaredfromsubway.eth is a sandwich bot that scans pending Ethereum transactions and inserts trades before and after them to capture price movement, and research has tied it to roughly 70% of tracked sandwich attacks on Ethereum between November 2024 and October 2025, generating an estimated $60 million a year in extracted value from other traders — even sandwich-attacking Ethereum co-founder Vitalik Buterin in a swap earlier this year.
Still Recovering From Its Own Exploit
The bot's recent trading also comes roughly seven weeks after it was on the losing end of a much larger hit. In June, security firm Blockaid documented how an attacker built a counter-MEV honeypot — fake token contracts and rigged liquidity pools designed to look like profitable opportunities — that tricked the bot into granting token approvals to attacker-controlled contracts. Those approvals were later used to sweep roughly $7.5 million in WETH, USDC and USDT from the bot in a single transaction, detailed in Blockaid's writeup of the incident.
A Predator That's Also Prey
Whether this week's buy-high-sell-low pattern reflects treasury rebalancing after the hack or simply routine trading volatility isn't clear from on-chain data alone. But for a system built specifically to extract value from other traders' bad timing, losing money on its own directional bets stands out — a reminder that MEV extraction and profitable trading are two different skills, and being good at one doesn't guarantee the other.

What It Signals for MEV Bot Risk
The pattern also reinforces a broader point security researchers made after the June exploit: automated systems that grant standing token approvals to unvetted contracts carry risk that applies well beyond MEV bots specifically, extending to market makers and trading firms running similar automated strategies on-chain.
