Trader Loses Over $200,000 in Costly Uniswap Swap

On March 12, 2025, at 09:04 AM UTC, a crypto trader suffered a massive loss of over $200,000 in a single swap on Uniswap V3. The transaction, recorded on Ethereum block 22029771, involved swapping 220,806 USDC but yielding only 5,272 USDT—resulting in a devastating loss.

Blockchain data flagged the transaction as an MEV (Maximal Extractable Value) transaction, meaning it bypassed the public mempool and was sent directly to block producers. This suggests the trader was likely exploited by arbitrage bots, capitalizing on the pricing inefficiencies in the swap.
