Crypto Trader在一项单务V3交易中不知不觉中损失了200,000美元以上

这项交易记录在以太坊22029771上，显示交易员交换了220,806 USDC，但仅获得了5,272 USDT的回报，这是巨大的损失。

A crypto trader lost over $200,000 in a single swap transaction on Uniswap V3, which was flagged by blockchain analytics platforms as an MEV Transaction.

一家加密交易员在Uniswap V3的一次交易交易中损失了超过20万美元，该交易是由区块链分析平台标记为MEV交易的。

The transaction, which occurred on March 12, 2025, at 09:04 AM UTC on Ethereum block 22029771, involved the trader swapping 220,806 USDC for 5,272 USDT, an enormous loss.

该交易发生于2025年3月12日，在以太坊块22029771上上午09:04，涉及交易者将220,806 USDC换成5,272 USDT，这是巨大的损失。

The transaction hash flagged it as an MEV Transaction, meaning it bypassed the public mempool and was sent directly to block producers, likely exploited by arbitrage bots.

交易哈希标记为MEV交易，这意味着它绕过了公共Mempool，并直接发送给了Block Producer，可能会被套利机器人利用。

The trader was attempting to swap 220,806 USDC for USDT on Uniswap V3, but due to an incorrectly set slippage tolerance or unfavorable routing, the swap executed at a highly unfavorable rate, leaving the trader with only 5,272 USDT instead of the expected amount.

交易者试图将220,806 USDC交换为USDT在UNISWAP V3上，但由于设置了不正确的滑板公差或不利的路由，以非常不利的速度执行掉期，使交易者只有5,272 USDT而不是预期的数量。

However, MEV bots identified the large USDC trade and submitted their own transactions before and after the trader’s swap, manipulating the price.

但是，MEV机器人确定了大型USDC贸易，并在交易者交换之前和之后提交了自己的交易，从而操纵价格。

This caused the trader’s swap to execute at an extremely unfavorable exchange rate, and the bots pocketed the difference, leaving the trader with just a fraction of their funds.

这导致交易者的互换以极为不利的汇率执行，机器人使差额袋装出来，使交易员只有一小部分资金。

The bots used their transactions to interfere with the trader’s trade on Uniswap V3, pivoting the price of USDC/USDT in their favor.

该机器人使用其交易来干扰交易者对Unistwap V3的交易，从而使USDC/USDT的价格转向了他们的利益。

The trader's transaction was broadcast directly to block producers (validators) via priority gas auction, while the bots' transactions were included in the public mempool.

交易者的交易直接通过优先气体拍卖直接广播给Block Prodister（验证者），而机器人的交易则包括在公共Mempool中。

The trader's transaction was then mined in the next block, with the bots' transactions manipulating the exchange rate to their advantage.

然后在下一个区块中开采了交易者的交易，机器人的交易操纵了汇率以发挥其优势。

The trader's transaction was executed at a terrible rate, leaving them with minimal USDT despite investing a large sum in USDC.

交易者的交易是以可怕的速度执行的，尽管在USDC上投资了大量款项，但它们的价格最低。

The optimal exchange rate at the time was around 440, and the trader's transaction executed at approximately 196, indicating a substantial loss due to MEV exploitation.

当时的最佳汇率约为440，交易者的交易约为196，这表明由于MEV剥削而造成了巨大损失。

This incident serves as a stark reminder of the importance of exercising caution and setting slippage values appropriately when engaging in cryptocurrency transactions.

这一事件迅速提醒人们在进行加密货币交易时谨慎行事并设定适当的滑移值的重要性。

Unfavorable slippage can lead to significant losses, especially for large trades, as bots may have the opportunity to manipulate prices and extract maximal extractable value (MEV).

不利的打滑可能会导致巨大的损失，尤其是对于大型交易，因为机器人可能有机会操纵价格并提取最大可提取价值（MEV）。

In the case of the crypto trader who lost over $200,000 in a single swap transaction on Uniswap V3, the trader's transaction was mined after two transactions by arbitrage bots, which exploited the trader's transaction to generate substantial gains.

如果加密货币交易员在单次交易中损失了超过200,000美元的uniswap v3交易，则交易者的交易是通过套利机器人进行两项交易后开采的，套利机器人进行了两笔交易，该交易利用了交易者的交易以产生可观的收益。

The trader attempted to swap 220,806 USDC for USDT, but the transaction executed at an appalling exchange rate, leaving them with only 5,272 USDT.

交易者试图将220,806美元的USDC换成USDT，但交易以令人震惊的汇率执行，仅占5,272 USDT。

The trader's transaction was broadcast directly to block producers using priority gas auction, while the bots' transactions were included in the public mempool and mined in the next block.

交易者的交易直接通过优先气体拍卖直接广播，以阻止生产商，而机器人的交易包括在公共Mempool中，并在下一个区块中开采。

The trader's transaction was then mined in the third block, with the bots' transactions manipulating the exchange rate to their advantage.

然后将交易者的交易在第三块区域开采，而机器人的交易操纵了汇率。

The optimal exchange rate at the time was around 440, and the trader's transaction executed at approximately 196, indicating that the trader lost a considerable amount due to MEV exploitation.

当时的最佳汇率约为440，交易者的交易约为196，这表明交易员由于MEV的利用而损失了相当大的金额。

The crypto trader's transaction was detected by blockchain analytics platforms and flagged as an MEV Transaction.

加密交易者的交易由区块链分析平台检测到，并被标记为MEV交易。

The transaction was spotted by crypto researcher and influencer DeFi Inspector.

该交易是由加密研究员和影响者DEFI检查员发现的。

"This is an insane story of how a crypto trader lost $200,000 in a single transaction," DeFi Inspector noted.

Defi Inspector指出：“这是一个疯狂的故事，讲述了一个加密货币交易员如何在一次交易中损失200,000美元。”

"The transaction was mined after 2 transactions by arbitrage bots, who exploited the trader’s transaction to generate a $190,000+ gain."

“交易是在两笔交易后通过套利机器人开采的，套利机器人利用交易者的交易产生了190,000美元以上的收益。”

“交易者的交易是直接广播的，以使用优先气体拍卖来阻止生产商，而机器人的交易被包括在公共孟买的公共场所中，并在下一个街区开采。”

“当时的最佳汇率约为440，交易员的交易约为196，这表明该交易员因MEV剥削而损失了相当大的金额。”

The researcher added that the trader's transaction was mined in the third block with a minimal gas fee, while the arbitrage bots paid a high gas fee to ensure their transactions were mined quickly and included in the next block.

研究人员补充说，交易员的交易是在第三块街区开采的，以最少的汽油费，而套利机器人则支付了高汽油费，以确保迅速开采其交易并将其包括在下一个区块中。
