Team's response as follows: Regarding this transaction, our investigation concludes: The user's exchange path this time was DOGESHIT → USDT, with an inquiry amount equivalent to approximately 3500+ USDT. The quote displayed on the page was 1838.43 USDT (slippage 0.015), while the final on-chain transaction executed at 1915.03 USDT. From the on-chain execution details, this transaction did not encounter a sandwich (MEV) attack. On the contrary, the user actually received about 70 USDT more than the quoted amount. Explanation for "why 3500U ultimately only exchanged for about 1900U": 1. **User manually restricted liquidity sources** In the quote request, the user excluded about 45 protocols, leaving only Uniswap V4, which severely limited the available paths and caused the price to deviate significantly from the market optimal. 2. **System clearly indicated high price impact** The page displayed a quote of 1838.43 USDT and already warned about "significant USD value difference before and after the exchange (Price Impact)." 3. **User proceeded with the transaction despite risk warnings** The final on-chain execution was 1915.03 USDT, which was better than the quoted result on the page. Comparison: • If the user had not manually filtered protocols (default to all protocols), OKX would have automatically selected the optimal path, resulting in a better price. • If only Uniswap V4 is selected, the path is restricted, and the price drops significantly. **Conclusion:** This issue is not due to a system error or attack but rather the user's active restriction of liquidity sources, leading to a lower quote. The system fully warned of the risks, and the final transaction result was better than the quoted amount.
