A single Ethereum address is responsible for 7% of the gas spent on the network in the last 24 hours.

According to data from EigenPhi, MEV bots executing sandwich attacks made $1.12 million on April 19, most of which came from one bot controlled by the user “jaredfromsubway.eth.”

The user spent 455 ETH worth around $950,000 in the process, and close to $7 million in gas fee over the course of the last two months in executing this strategy.

“After closing the day of yesterday with a profit close to $1M, jaredfromsubway.eth MEV bot is already profiting close to $400K today,” wrote on-chain researcher “” on Twitter.

MEV sandwich attacks are a type of front-running, where the bot profits from an artificial increase in price by placing a so-called “sandwich trade” before and after a large-pending transaction. The attacker essentially buys the asset from the victim lower than the market value, and then sells it, making a profit from the difference between the sale and gas fee.

Unsuspecting users often fall victim to this type of attack, without necessarily being aware that they have been front-run by a transaction.

(Ethereum Foundation researcher Justin Drake and bloXroute Labs CEO Uri Klarman discuss why MEV will always be controversial in this episode of Unchained.)

The plethora of MEV-related front running prompted a consortium of Ethereum developers to launch a solution dubbed MEV Blocker for everyday users to protect themselves.

Most of jaredfromsubway.eth’s trades were executed on PEPE trades. PEPE, a memecoin launched on April 14, has sparked a trading frenzy and amassed a market cap of close to $120 million just a few days after its launch.

“Sandwich bots are eating so good because there’s a ton of new people buying coins that don’t know how to minimize slippage. If you don’t want to get rekt, consider using a private relay (e.g. flashbots) or make sure your slippage is tuned just above fees with high gas,” wrote crypto trader “wave” on Twitter.
