Uniswap user V3, who appears to have confused one token with another when creating a liquidity pool, lost more than $700,000 on the morning of November 4th due to a MEV-related transaction. It appears that the user accepted the value of the Curve DAO token (CRV) for the US dollar when he added $1.56 million worth of wrapped BTC to the liquidity pool. However, in return the user received 1.56 million CRV. at that time it was worth only $850,000. According to analytical company Arkham, MEV bots rushed to use arbitrage, the most successful of them received a profit of only $260, paying validators $527,000 to get ahead of other bots and complete the transaction first. “Unlucky,” they wrote on the Arkham account.
In the transaction, the so-called "full finger" is not used in the cryptocurrency. Option B allows the user to exchange an amount greater than $1,000 in USDR or USDC in USDC or USDC in USDC.
