A crypto trader was the victim of a sandwich attack while carrying out a stablecoin transfer of $ 220,764 on March 12 – losing almost 98% of its value to a boot with maximum extractable value (MEV).
$ 220,764 of the Part of the Part USD (USDC) part was exchanged at $ 5,271 from TETH (USDT) in eight seconds while the BOT MEV managed to be forward the transaction, depending on more than $ 215,500.
Ethereum Block Explorer’s data show that the MEV attack occurred on the USDC-USDT liquidity pool for the exchange of the exchange of the Uniswap V3 exchange, where $ 19.8 million in value are locked.

The MEV BOT transaction the transaction by exchanging all USDC liquidity of the USDC-USDT POOL USDC V3, then handed it over after the execution of the transaction, according to the founder of the DEFI report Michael Nadeau.
The attacker switched Ethereum Block Builder “Bob–builder.eth” $ 200,000 from the $ 220,764 swap and took advantage of $ 8,000 themselves, said Nadeau.
The Defi researcher “Defiac” speculates the same merchant using different portfolios was the victim of a total of six sandwich attacks, citing “internal tools”. They pointed out that all the funds had come from the borrowing and loan protocol before being deposited on Uniswap.
Two of the portfolios were victims of a sandwich attack at the Bot Mev on March 12 around 9:00 am UTC. Ethereum Wallet addresses “0xdde … 42A6D” and “0x999 … 1D215” were attacked in sandwich for $ 138,838 and $ 128,003 in transactions that occurred three to four minutes earlier.
The two transactors made the same exchange in the UNISWAP V3 liquidity pool as the merchant who made the transfer of $ 220,762.
Others speculate that trades could be attempted money laundering.
“If you have NK illicit funds, you could build a very half TX, then send it privately to a Bot Mev and make them ARB in a package,” said the founder of the Crypto Data Defillama dashboard, 0xngmi.
“In this way, you wash all the money with almost 0 losses.”

While criticizing Uniswap initially, Nadeau later recognized that the transactions do not come from the frontal of Uniswap, which has protective and default shift parameters.
Nadeau has made income on these criticisms after the CEO of Uniswap, Hayden Adams and others, has clarified the protections that the UNISWAP has in place to fight against sandwich attacks.
