CoinVoice has learned that, according to the latest market information, the DeFi protocol YO Protocol experienced an abnormal Swap event on Ethereum, where users exchanged approximately $3.84 million worth of stkGHO for only about $122,000 USDC. Analysis indicates that the incident was caused by a combination of two factors: 1) the initiator submitted an incorrect estimated output value, causing the slippage protection to become ineffective; 2) the transaction path was set abnormally, passing through high-fee, low-liquidity pools, resulting in significant fee extraction and price impact. The team has now purchased GHO and redeposited stkGHO in an attempt to remedy the situation.
