对稳定股份交换的三明治攻击额定为加密货币交易者$ 215,500，突出了该领域的风险。

该事件突出了许多重大问题：安全性与透明度：即使区块链透明度确保了无信任度，但它仍将商人暴露于诸如三明治攻击之类的潜在弱点。

A cryptocurrency trader suffered significant losses after becoming a victim of a sandwich attack on Uniswap, a popular decentralized exchange (DEX), aiming to swap USD Coin (USDC) for Tether (USDT). The trader, who had expressed gratitude for the event, initially attempted to exchange USDC, valued at $220,764, for USDT on Uniswap.

加密货币交易员在成为对uniswap的三明治攻击的受害者（dex）的受害者，旨在将USD Coin（USDC）换成Tether（USDT）。对这项活动表示感谢的交易者最初试图兑换USDC，价值220,764美元，在UNISWAP上为USDT提供了220,764美元。

However, the trader ended up with only $5,271 USD from the sandwich assault, resulting in a substantial loss. According to Michael Nadeau, founder of the DeFi Report, data from the Ethereum block reveals that the MEV attack occurred on Uniswap v3’s USDC-USDT liquidity pool.

但是，交易者最终仅获得了三明治袭击的5,271美元，造成了巨大的损失。根据DEFI报告的创始人迈克尔·纳多（Michael Nadeau）的说法，以太坊块的数据表明，MEV攻击发生在Uniswap V3的USDC-USDC-USDT流动性池中。

A sandwich attack, also known as a MEV attack, is a type of front-running where a malicious actor discovers a pending transaction and submits two orders: a purchase order immediately before the target transaction and a sell order immediately after.

三明治攻击，也称为MEV攻击，是一种前进的类型，恶意演员发现了待处理的交易并提交了两个订单：立即在目标交易前的采购订单和后立即提交卖出订单。

In this case, the attacker's purchase order increased the token's price, while the subsequent sell order, after the victim's transaction was executed, decreased the token's price. This manipulation forced the victim to purchase the token at a higher price and sell it at a lower price.

在这种情况下，攻击者的采购订单提高了令牌的价格，而后续的卖出订单在执行受害者交易后，降低了令牌的价格。这种操纵迫使受害者以较高的价格购买令牌，并以较低的价格出售它。

Furthermore, DeFiac, a renowned DeFi researcher, noted that the same trader, using different wallets, fell victim to a total of six sandwich attacks. Internal tools revealed that all funds traveled from Aave before being deposited on Uniswap.

此外，著名的Defi研究人员Defiac指出，使用不同钱包的同一位交易员总共遭受了六次三明治袭击的受害者。内部工具显示，所有资金都从AAVE返回，然后再存入UNISWAP。

The attacker searched for large, unprocessed transactions, typically over $100,000, to maximize their potential gains. Upon locating a target, the attacker would increase the item's price by filing a buy order for the same item.

攻击者搜索了大型未经处理的交易，通常超过100,000美元，以最大程度地提高其潜在收益。找到目标后，攻击者将通过向同一商品提交买入订单来提高项目的价格。

For instance, if the victim planned to exchange 100,000 USDC for USDT at a price of 1.01, the attacker would submit a limit order to buy 50,000 USDC at 1.01. This action would raise the price of USDC, and the best price at which the victim could sell his 100,000 USDC would become 1.01.

例如，如果受害人计划以1.01的价格将100,000美元的USDT交换为USDT，则攻击者将提交限额订单，以1.01的价格购买50,000 USDC。这项行动将提高USDC的价格，受害者可以出售100,000美元的最优惠价格将成为1.01。

As a result, the victim's trade would be executed at this inflated price, and he would receive fewer USDT than anticipated. To capitalize on this discrepancy, the attacker would then place a sell order for 50,000 USDC at the new, higher price, which was 1.01 in this case.

结果，受害者的贸易将以这个高昂的价格执行，他的USDT将比预期的少。为了利用这一差异，攻击者将以新的价格更高的价格下达50,000美元的卖出订单，在这种情况下为1.01。

This attack method is applicable to any token on Uniswap v3, and traders can take precautions to mitigate the risk.

这种攻击方法适用于Unistwap V3上的任何令牌，交易者可以采取预防措施来减轻风险。
