The TRON myrose.finance DeFi project is not refundable in USDT

According to BBNews, on the evening of September 14, there was an issue where the USDT pool could not be removed from the TRON DeFi myrose.finance project. We use the SafeERC20 library, and after calling the SafeTransfer function library, call the external USDT contract exchange function to determine the return value.

Therefore, when SafeTransfer calls, the return value becomes false, which prevents the user from issuing a good refund. The SlowMist security team believes that when considering trading USDT to TRON, they should pay special attention to the rate of return risk of the exchange, other changes in the USDT contract. , and test everything before the plan begins to prevent a mishap.
