一名加密货币交易员在3月12日遭受了昂贵的三明治袭击的受害者，在试图交换stablecoins时损失了超过215,000美元。

A crypto trader fell victim to a costly sandwich attack on March 12, losing more than $215,000 while trying to swap stablecoins.

一名加密货币交易员在3月12日遭受了昂贵的三明治袭击的受害者，在试图交换稳定的同时损失了21.5万美元。

The attack happened on Uniswap v3’s USDC-USDT liquidity pool and highlighted the dangers of Maximum Extractable Value (MEV) bots in decentralized finance.

袭击发生在Uniswap V3的USDC-USDT流动性池中，并强调了分散融资中最大可提取价值（MEV）机器人的危险。

The trader started with $220,764 in USD Coin (USDC) to swap for Tether (USDT). What should have been a routine swap between stablecoins turned into a disaster. In just eight seconds, the victim was left with only $5,271 in USDT.

该交易员以220,764美元的价格在美元硬币（USDC）开始，以交换Tether（USDT）。应该是稳定币之间的常规交换变成了一场灾难。在短短八秒钟内，受害者在USDT中只剩下5,271美元。

This represents a loss of nearly 98% of the original value. The attack took place on Uniswap v3’s USDC-USDT liquidity pool, which currently holds about $19.8 million in locked value.

这代表了近98％的原始价值损失。这次袭击发生在UNISWAP V3的USDC-USDT流动性池中，目前持有约1980万美元的锁定价值。

The MEV bot carried out what experts call a “sandwich attack.” This involved the bot front-running the victim’s transaction. The attacker first removed all USDC liquidity from the pool before the victim’s swap went through.

MEV机器人进行了专家所说的“三明治攻击”。这涉及机器人前进受害者的交易。攻击者首先在受害者交换之前从游泳池中删除了所有USDC流动性。

After the victim’s transaction executed at a terrible exchange rate, the bot returned the liquidity to the pool. This type of attack is named for how it “sandwiches” the victim’s transaction between two bot transactions.

受害人的交易以可怕的汇率执行后，机器人将流动性返回了游泳池。这种攻击以如何“三明治”在两项机器人交易之间的交易中命名。

Michael Nadeau, founder of The DeFi Report, shared details about how the profits were split. The attacker paid the Ethereum block builder known as “bob-the-builder.eth” a $200,000 tip from the stolen funds. The bot operator kept around $8,000 as their own profit.

DEFI报告的创始人迈克尔·纳多（Michael Nadeau）分享了有关如何分配利润的详细信息。攻击者向以太坊建筑商支付了“ Bob-the-Builder.eth”，这是从被盗的资金中获得的20万美元小费。该机器人运营商将自己的利润保留在8,000美元左右。

Is anyone safe using DeFi?A user on @Uniswap v3 was just sandwiched attacked out of $216k while simply trying to swap $221k USDC to USDT.

有人使用defi安全吗？

Mind you, this was a pool that had over $35m of USDC and USDT it.

请注意，这是一个拥有超过3500万美元的USDC和USDT的游泳池。

This is insane.

这太疯狂了。

This may not be an isolated incident. DeFi researcher "DeFiac" believes the same trader was targeted multiple times on the same day. Using internal tools, the researcher found evidence suggesting the trader was hit by six sandwich attacks in total.

这可能不是孤立的事件。 Defi研究人员“ Defiac”认为同一交易员在同一天被多次瞄准。研究人员使用内部工具发现了证据表明，交易者总共遭受了六次三明治攻击。

Two other wallet addresses linked to the same trader were also attacked earlier that day. The wallets "0xDDe...42a6D" and "0x999...1D215" lost $138,838 and $128,003 in similar attacks. These attacks happened just minutes apart from each other.

当天早些时候，与同一交易员相关的另外两个与同一交易员有关的钱包地址也受到袭击。钱包“ 0xdde ... 42A6D”和“ 0x999 ... 1D215”损失了$ 138,838和$ 128,003的类似攻击。这些攻击彼此相距仅几分钟。

Unknown entity got sandwiched for 714k today on six separate USDC -> USDT swaps. (Traded with 100% slippage allowed.)

未知的实体今天在六个单独的USDC-> USDT交换中将714K夹在714K上。 （允许以100％的滑倒交易。）

They swapped 732583.429405 USDC for 18636.232611 USDT.

他们将732583.429405 USDC交换为18636.232611 USDT。

All the attacked transactions followed the same pattern. The funds first moved from Aave, a popular borrowing and lending protocol. Then they were deposited into the same Uniswap v3 USDC-USDT pool where the attacks took place.

所有攻击交易都遵循相同的模式。资金首先从AAVE（一种流行的借贷和贷款协议）移动。然后，它们被存放到发生袭击发生的同一UNISWAP V3 USDC-USDT池中。

Some experts have raised the possibility that these unusually bad trades might be connected to money laundering. 0xngmi, the founder of crypto data dashboard DefiLlama, suggested this could be a method to wash illicit funds.

一些专家提出了这些异常糟糕的交易可能与洗钱有关的可能性。 Crypto Data Dashboard Defillama的创始人0xngmi建议这可能是洗涤非法资金的一种方法。

This theory involves creating transactions that are easily exploitable by MEV bots. By privately sending these transactions to specific bots, someone could potentially launder money while accepting the losses as a cost of cleaning the funds.

该理论涉及创建可以通过MEV机器人轻松利用的交易。通过将这些交易私下发送给特定的机器人，有人可能会洗钱，同时接受损失作为清理资金的成本。

Uniswap CEOInitially, some critics blamed Uniswap for the incident. However, Uniswap CEO Hayden Adams quickly clarified that these transactions did not come through Uniswap’s official interface.

单税在Ceoination上，一些批评家将事件归咎于UNISWAP。但是，UNISWAP首席执行官海登·亚当斯（Hayden Adams）很快澄清说，这些交易不是通过UNISWAP的官方界面进行的。

The Uniswap front-end includes built-in MEV protection features. It also has default slippage settings that would have prevented such losses. Slippage refers to the difference between expected and actual prices in a trade.

UNISWAP前端包括内置的MEV保护功能。它还具有默认的滑移设置，可以防止这种损失。打滑是指交易中预期价格和实际价格之间的差异。

Users who access Uniswap through its official interface benefit from these protections. However, those who interact with the protocol through other means may remain vulnerable to such attacks.

通过其官方界面访问Uniswap的用户受益于这些保护。但是，那些通过其他方式与协议互动的人可能仍然容易受到此类攻击的影响。

This incident serves as a reminder of the risks in decentralized finance. Even when trading between stablecoins, which should maintain steady values, traders can fall victim to technical exploits.

该事件提醒人们分散金融的风险。即使在应保持稳定价值的稳定币之间进行交易，交易者也可能成为技术利用的受害者。

MEV attacks continue to be a problem in the DeFi ecosystem. They allow sophisticated bots to extract value from regular users’ transactions, often without those users even realizing what happened.

MEV攻击在Defi生态系统中仍然是一个问题。它们允许复杂的机器人从常规用户的交易中提取价值，通常没有这些用户甚至意识到发生了什么。
