YO Protocol suffers abnormal swap transaction, approximately $3.84 million worth of stkGHO exchanged for only $122,000 USDC

PANews reported on January 13 that, according to BlockSec, the DeFi protocol YO Protocol experienced an abnormal Swap event on Ethereum, where a user exchanged approximately $3.84 million worth of stkGHO for only about $122,000 USDC. Analysis indicates that the incident was caused by two combined factors: 1) The initiator submitted an incorrect estimated output value, rendering slippage protection ineffective; 2) The transaction path was set abnormally, passing through pools with high fees and low liquidity, resulting in significant fee extraction and price impact. Currently, the team has purchased GHO and re-deposited it into stkGHO in an attempt to remedy the situation.
