MEV giant Jaredfromsubway.eth lost $7.5 million in a sophisticated smart contract attack.
One of the most famous MEV bots on the Ethereum network — Jaredfromsubway.eth — has suffered catastrophic losses exceeding $7.5 million. The incident occurred as a result of a complex attack that does not fall under classic phishing schemes or standard smart contract vulnerabilities.
How the Attack Was Carried Out
According to data from the analytical platform Blockaid, the attacker deployed dozens of fake token contracts disguised as popular assets: WETH, USDC, and USDT. These contracts were linked to fake liquidity pools that visually mimicked profitable trades. MEV bots typically respond to such operations to execute sandwich attacks.
The scheme was designed in such a way that the bot's automated execution system granted the attacker's auxiliary contracts permissions to spend real assets. After that, the attacker activated all backdoors in a single transaction and withdrew the funds. Part of the stolen coins has already been transferred to Tornado Cash, as confirmed by data from Arkham.
Scale of the Problem and Context
This incident highlights the vulnerability of even the most advanced MEV strategies. By my estimates, annual trader losses in Ethereum from sandwich attacks amount to approximately $60 million. From November 2024 to October 2025, the network recorded between 60,000 and 90,000 such operations monthly. Notably, about 70% of them were linked specifically to Jaredfromsubway.eth.
Recall that in June 2024, this MEV bot became the largest consumer of gas in Ethereum, demonstrating its dominant position in the ecosystem. However, the current attack shows that even such giants are not immune to targeted manipulations.
Analytical Commentary: This case is a vivid example of how MEV bots, created to extract profit from market inefficiencies, themselves become victims of more sophisticated schemes. This raises questions about the security of automated trading systems and the need to implement more reliable transaction verification mechanisms. In the long term, such incidents may stimulate the development of more transparent and secure protocols for MEV operations.
