Unlucky MEV Bot Suffers Loss in Sandwich Attack

不幸的 MEV 機器人在三明治攻擊中遭受損失

An unfortunate Maximum Extractable Value (MEV) bot incurred a hefty $11.9 million flash loan for a sandwich attack, only to barely break even.

不幸的是，最大可提取價值 (MEV) 機器人因三明治攻擊而獲得了 1,190 萬美元的巨額快速貸款，但勉強收支平衡。

On September 5th, Arkham Intelligence disclosed that the MEV bot utilized $11.97 million in Wrapped Ether (WETH) to surround a user attempting to swap $5,000 worth of Shuffle (SHFL) tokens. Despite the significant loan amount, the bot netted a mere $20 after deducting gas fees.

9 月 5 日，Arkham Intelligence 披露，MEV 機器人利用 1,197 萬美元的 Wrapped Ether (WETH) 包圍了一名試圖交換價值 5,000 美元的 Shuffle (SHFL) 代幣的用戶。儘管貸款金額很大，但扣除汽油費後，機器人僅淨賺 20 美元。

The bot involved in this incident is said to have made 14 transactions, transferring over $700,000 in USDC and WETH across DeFi platforms such as Aave and Uniswap. Remarkably, these transactions were processed within a single block, indicating the bot's swift execution within 12 seconds.

據稱，參與本次事件的機器人已進行 14 筆交易，在 Aave 和 Uniswap 等 DeFi 平台上轉移了超過 70 萬美元的 USDC 和 WETH。值得注意的是，這些交易是在單個區塊內處理的，這表明機器人在 12 秒內快速執行。

Understanding Sandwich Attacks

了解三明治攻擊

Sandwich attacks involve attackers placing two transactions around a victim's trade. They manipulate the price by purchasing assets before the victim and selling them afterward, profiting from the difference. However, in this instance, the MEV bot's profits were underwhelming.

三明治攻擊涉及攻擊者圍繞受害者的交易放置兩筆交易。他們透過在受害者之前購買資產並隨後出售來操縱價格，從差價中獲利。然而，在這種情況下，MEV 機器人的利潤卻並不理想。

MEV bots have historically been known to generate substantial returns. In April 2023, a bot operator known as 'jaredfromsubway' earned over $1 million in just one week through sandwich attacks on PEPE and WOJAK tokens. Despite the setback experienced by this particular bot, MEV attacks continue to offer significant profitability for many operators.

MEV 機器人歷來以能產生可觀的回報而聞名。 2023 年 4 月，一位名為「jaredfromsubway」的機器人營運商透過對 PEPE 和 WOJAK 代幣的三明治攻擊，在短短一周內賺取了超過 100 萬美元。儘管這個特定的機器人遭遇了挫折，MEV 攻擊仍然為許多營運商帶來了可觀的利潤。
