UNISWAP V3三明治攻击者从一笔交易中抢购732,000美元（澳元110万美元）

OnChain数据显示，单个加密货币交换中的损失巨大：一名交易员在USDC中以超过732,000美元的价格交换了732,000美元（100万美元），仅在USDT中以大约19k（au $ 30k）的价格交换。

On-chain data has revealed a staggering loss in a single cryptocurrency swap, with a trader exchanging over US$732,000 (AU$1.1M) in USDC for only about US$19K (AU$30K) in USDT.

链上的数据显示，单个加密货币交换中的损失巨大，一家交易员在USDC中以超过732,000美元的价格交换了732,000美元（AU 110万美元），仅在USDT中以19k美元（AU $ 30K）的价格交换。

The transaction was carried out on Uniswap V3’s highly liquid USDC–USDT pool and it appears to have been manipulated by a sandwich attack — a tactic in which an attacker places transactions both before and after a victim’s order to force an unfavorable price movement.

该交易是在Uniswap V3高度液体USDC – USDT池上进行的，并且似乎是通过三明治攻击来操纵的 - 这种策略在这种策略中，攻击者在受害者命令之前和之后都将交易施加了不利的价格移动。

In this case, an MEV bot is believed to have front-run the trader’s transaction by draining liquidity from the pool, creating a massive price discrepancy between two stablecoins that are usually pegged to one US dollar. The bot also tipped a block builder to ensure its transaction was processed ahead of the victim’s.

在这种情况下，据信，MEV机器人通过从游泳池中排出流动性来使交易员的交易领先，从而在两个通常将其固定在一美元的稳定中造成了巨大的价格差异。该机器人还向块建造者倾斜，以确保其交易在受害者的前面处理。

Some observers have speculated that these unusually poor swap outcomes might not be accidental and could be a money laundering mechanism.

一些观察者推测，这些异常差的掉期结果可能不是偶然的，可能是一种洗钱机制。

The DEFiac noted that all wallets follow the same path, which is “unusual”.

Dafiac指出，所有钱包都遵循相同的路径，这是“不寻常的”。

In another instance, a trader appears to have lost over US$400K (AU$630K) in a single swap as they exchanged USDC for a small amount of another token.

在另一种情况下，交易者似乎单次交换损失了超过40万美元（AU $ 630k），因为他们将USDC换成了少量的其他令牌。
