本文報導了在加密貨幣交易期間發生的三明治襲擊事件，在交易交易者交換穩定時，交易員損失了21.5萬美元。

A crypto trader had nearly 98% of the value in a $220,764 stablecoin transfer wiped out by an MEV bot performing a sandwich attack.

一個加密交易員在220,764美元的Stablecoin轉移中，由MEV機器人進行了三明治攻擊，將近98％的價值轉移。

The trader lost $215,500 while the bot netted a profit when $220,764 worth of USDC stablecoin was swapped for $5,271 worth of Tether USDT in just eight seconds.

Data from the Ethereum block explorer shows the MEV attack took place in the USDC-USDT liquidity pool on decentralized exchange Uniswap v3, which had assets worth $19.8 million locked.

According to Michael Nadeau, founder of The DeFi Report, the MEV bot front-ran the transaction by pulling all the USDC liquidity out of Uniswap v3's USDC-USDT pool and then returning it after the trade was completed.

根據DEFI報告的創始人邁克爾·納多（Michael Nadeau）的說法，MEV機器人前進的交易是通過將所有USDC流動性從Uniswap V3的UNISDC-USDC-USDT池中拉出，然後在交易完成後將其退回。

The attacker then paid a $200,000 tip to Ethereum block builder “bob-the-builder.eth” out of the $220,764 transaction and made an $8,000 profit.

然後，攻擊者向以太坊建築商“ Bob-the-Builder.eth”支付了200,000美元的小費，從220,764美元的交易中支付了8,000美元的利潤。

DeFi researcher ‘DeFiac’ speculates that the same trader using different wallets may have encountered a total of six sandwich attacks, citing “internal tools” for analysis. They add that all the funds originated from lending protocol Aave before being deposited into Uniswap.

Defi研究人員“ Defiac”推測，使用不同錢包的同一交易員可能遇到了六次三明治攻擊，理由是“內部工具”進行分析。他們補充說，所有資金均來自貸款方案AAVE，然後再將其存入UNISWAP。

Two of the traders fell victim to the MEV bot sandwich attack around 9 AM UTC on March 12. The Ethereum wallet addresses “0xDDe…42a6D” and “0x999…1D215” were sandwich attacked in transactions that occurred three to four minutes earlier, losing $138,838 and $128,038, respectively.

3月12日上午9點左右，兩名交易者成為MEV Bot三明治襲擊的受害者。以太坊錢包介紹了“​​ 0xdde…42A6D”和“ 0x999…1d215”，在三到四分鐘之前發生了三到四分鐘的交易，遭受了三到四分鐘的攻擊，損失了138,838 $ 138,838和$ 128,038和128,038美元。

Both of these traders carried out the same trade in the Uniswap v3 liquidity pool when they executed a large portion of the USDC-USDT liquidity.

這兩個交易員在執行USDC-USDT流動性的大部分時間時，在Unistwap V3流動性池中進行了相同的貿易。

There is speculation that these transactions may be related to money laundering.

猜測這些交易可能與洗錢有關。

0xngmi, founder of the crypto data dashboard DefiLlama, said: "If you have NK illegal funds, you can construct a trade that is very easily susceptible to MEV attacks, then privately send it to an MEV bot and let them arbitrage it in a bundle. This way, named you can wash all the money with almost zero loss."

Crypto Data Dashboard Defillama的創始人0xngmi說：“如果您擁有NK非法資金，您可以構建一種非常容易受到MEV攻擊易受的交易，然後將其私下發送給MEV機器人，並讓他們以捆綁措施索要它。這樣，您可以將所有的錢洗淨而所有的錢。”
