This morning, a Uniswap V3 user lost over $700,000 in just 12 seconds due to an MEV-related transaction. The user mistakenly added $1.56 million worth of wrapped BTC to a liquidity pool, thinking it was worth the same as the Curve DAO token (CRV) in USD. However, they received 1.56 million CRV in return, which was only worth around $850,000 at the time. MEV bots took advantage of the situation, but the most successful only made a profit of around $260 after paying a $527,000 bribe to validators. Mistakes like this are not uncommon in the crypto world and are often referred to as "fat finger" errors.
