JaredfromSubway.eth sandwich attack bot has accumulated $295 million, with $7.5 million stolen in June

The sandwich attack bot operated by JaredfromSubway.eth has extracted a total of 117,007 ETH since March 2023, amounting to approximately $295 million at current prices. In June 2026, an anonymous attacker deployed 66 counterfeit token contracts, using the bot's automated trading logic to steal at least $7.5 million in ETH and stablecoins, transferring the funds to Tornado Cash; the related assets have not yet been recovered.

Sandwich attacks are a form of Maximum Extractable Value (MEV): the bot monitors large transactions in the Ethereum public mempool, buys before the target transaction, and sells after the transaction drives up the price, extracting profits from the price difference. As of August 28, the main contract of the bot has received a total of 117,007 ETH.

MEV-Boost block construction is concentrated among a few participants, with relay.ultrasound.money, Titan Relay, and bloXroute relays forwarding approximately 85% to 88% of the relevant blocks within a 24-hour window; Titan's builders independently assemble 50.3% of the blocks. The monthly extraction amount from sandwich attacks has decreased from about $10 million at the end of 2024 to about $2.5 million in October 2025.
