加密貨幣交易員在uniswap v3上進行了220,764美元的Stablecoin轉移，成為了三明治襲擊的受害者

MEV機器人前部運行交易，通過將所有USDC流動性從UNISWAP v3 USDC-USDT池中匯總出來，然後將其放回原處

A crypto trader fell victim to a sandwich attack while making a $220,764 stablecoin transfer on March 12, losing almost 98% of its value to a Maximum Extractable Value (MEV) bot.

一名加密貨幣交易員在3月12日進行了220,764美元的Stablecoin轉會，造成了三明治攻擊的受害者，其價值的近98％損失為最大可提取價值（MEV）機器人。

The trader lost $215,494 after attempting to swap the $220,764 to another stablecoin, Tether (USDT), on decentralized exchange Uniswap v3. The stablecoin was part of a larger sum borrowed from borrowing and lending protocol Aave.

交易者在嘗試將$ 220,764交換給另一個穩定的交易所UNISWAP V3後，損失了215,494美元。穩定幣是從借款和貸款方案AAVE中藉來的較大款項的一部分。

The transaction was swiftly canceled three to four minutes earlier by an MEV bot, which used the opportunity to swap out all the USD Coin (USDC) liquidity on Uniswap v3 and put it back in after the transaction was executed.

MEV機器人在三到四分鐘之前迅速取消了該交易，該機器人藉此機會在UNISWAP V3上交換了所有美元硬幣（USDC）流動性，並在執行交易後將其放回原處。

The attacker, who tipped Ethereum block builder “bob-the-builder.eth” $200,000 from the $220,764 swap, managed to profit $8,000 from the transaction, according to founder of The DeFi Report Michael Nadeau.

根據DEFI報告的創始人Michael Nadeau的創始人，攻擊者向以太坊建築商“ Bob-the-builder.eth”提出了20萬美元的交換，從220,764美元的交易中付出了200,000美元，該交易已從交易中獲利8,000美元。

DeFi researcher “DeFiac” speculates the same trader using different wallets has fallen victim to a total of six sandwich attacks, citing “internal tools.” They pointed out that all funds traveled from Aave before being deposited on Uniswap.

Defi研究人員“ Difiac”推測使用不同錢包的同一交易員因“內部工具”為六次三明治襲擊而成為了受害者。他們指出，所有資金都從AAVE返回，然後才存入UNISWAP。

Two of the wallets fell victim to an MEV bot sandwich attack on March 12 at around 9:00 am UTC. Ethereum wallet addresses “0xDDe…42a6D” and “0x999…1D215” were sandwich attacked for $138,838 and $128,003 in transactions that occurred three to four minutes earlier.

其中兩個錢包在3月12日上午9:00左右撞到了MEV機器人三明治襲擊的受害者。以太坊錢包以“ 0xdde…42a6d”和“ 0x999…1d215”介紹了三明治，以138,838美元的價格攻擊，而交易的128,003美元發生在三到四分鐘之前。

Both transactors made the same swap in the Uniswap v3 liquidity quickly and had the same interesting routing on Aave.

這兩個交易儀都在Uniswap V3流動性中迅速互換，並在AAVE上具有相同的有趣路由。

“If you have NK illicit funds you could construct a very mev-able tx, then privately send it to a mev bot and have them arb it in a bundle,” said founder of crypto data dashboard DefiLlama, 0xngmi.

“如果您有NK非法資金，您可以構建非常可MEV的TX，然後將其私人發送給MEV機器人，並將其捆綁在一起，” Crypto Data Dashboard Defillama（0xngmi）的創始人說。

“That way you wash all the money with close to 0 losses.”

“這樣，您就以接近0的損失洗了所有錢。”

While initially criticizing Uniswap, Nadeau later acknowledged that the transactions didn't come from Uniswap's front end, which has MEV protection and default slippage settings.

儘管最初批評Uniswap，但納多後來承認，交易並非來自Uniswap的前端，該前端具有MEV保護和默認的打滑設置。

Nadeau backtracked on those criticisms after Uniswap CEO Hayden Adams and others clarified the protections Uniswap has in place to fight against sandwich attacks.

在Uniswap首席執行官海登·亞當斯（Hayden Adams）和其他人澄清了Uniswap對抗三明治襲擊的保護方面，納多（Nadeau）回溯了這些批評。
