加密货币交易员在uniswap v3上进行了220,764美元的Stablecoin转移，成为了三明治袭击的受害者

MEV机器人前部运行交易，通过将所有USDC流动性从UNISWAP v3 USDC-USDT池中汇总出来，然后将其放回原处

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.

一名加密货币交易员在3月12日进行了220,764美元的Stablecoin转会，造成了三明治攻击的受害者，其价值的近98％损失为最大可提取价值（MEV）机器人。

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.

交易者在尝试将$ 220,764交换给另一个稳定的交易所UNISWAP V3后，损失了215,494美元。稳定币是从借款和贷款方案AAVE中借来的较大款项的一部分。

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机器人在三到四分钟之前迅速取消了该交易，该机器人借此机会在UNISWAP V3上交换了所有美元硬币（USDC）流动性，并在执行交易后将其放回原处。

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.

根据DEFI报告的创始人Michael Nadeau的创始人，攻击者向以太坊建筑商“ Bob-the-builder.eth”提出了20万美元的交换，从220,764美元的交易中付出了200,000美元，该交易已从交易中获利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研究人员“ Difiac”推测使用不同钱包的同一交易员因“内部工具”为六次三明治袭击而成为了受害者。他们指出，所有资金都从AAVE返回，然后才存入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.

其中两个钱包在3月12日上午9:00左右撞到了MEV机器人三明治袭击的受害者。以太坊钱包以“ 0xdde…42a6d”和“ 0x999…1d215”介绍了三明治，以138,838美元的价格攻击，而交易的128,003美元发生在三到四分钟之前。

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

这两个交易仪都在Uniswap V3流动性中迅速互换，并在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非法资金，您可以构建非常可MEV的TX，然后将其私人发送给MEV机器人，并将其捆绑在一起，” Crypto Data Dashboard Defillama（0xngmi）的创始人说。

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

“这样，您就以接近0的损失洗了所有钱。”

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.

尽管最初批评Uniswap，但纳多后来承认，交易并非来自Uniswap的前端，该前端具有MEV保护和默认的打滑设置。

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首席执行官海登·亚当斯（Hayden Adams）和其他人澄清了Uniswap对抗三明治袭击的保护方面，纳多（Nadeau）回溯了这些批评。
