Title: What happened with the UNI/USDT trading pair on Uniswap? Post by: JeromeTash on January 21, 2023, 11:09:57 AM Since I am not a user of Uniswap, I am a little unfamiliar with this situation.
The UNI/USDT price was weird at some point, costing roughly $644 per token according to dextools. What is going on? Is it a case of market manipulation, accidental buying and selling, or some sort of scam? https://www.dextools.io/app/en/ether/pair-explorer/0x5ac13261c181a9c3938bfe1b649e65d10f98566b https://talkimg.com/images/2023/05/14/blob8bc73e5b7a0b7edf.png https://talkimg.com/images/2023/05/14/bloba34fdb5f0f792f38.png Title: Re: What happened with the UNI/USDT trading pair on Uniswap?

The victim is transaction #2, that trx paid $63k/UNI and lost about $50 USDT. Here's how it works:

From this sandwich attack, the attacker gained 28 USDT and paid around $25 in ETH for gas, making only $3 net profit. Yeah these MEV bots are crazy.

I will look it up, it will be worth readingI noticed that it happened again a few hours ago and one striking thing is the middle transaction, the one we think is the victim, always has the same values (the price in USD, Amount in UNI, Total USDT etc) just like the previous incident. Something is definitely up :D https://talkimg.com/images/2023/05/14/blob78264deabb09f16d.png |
