Summary

No form of balance check before token transfer

Vulnerability Details

The absence of this check can cause a sender to initiate a conversion of fees token more than that of his balance

Impact

This can result in function execution failure, loss of fees or incomplete token conversion(which will make the event indicating completion of token conversion to not be emitted )

VS Code Manual Review

Recommendations

Adding "require(LibSilo.balanceOf(msg.sender, fromToken) >= fromAmount, "Insufficient balance for conversion");" will remediate this issue
