| Low | 2 | 0 | 2 |
MediumToken deflationFixed
The recording of `TokenVesting` does not consider the token deflation. It should record the actually transferred amount rather than the parameter amount.
LowImproper Usage of `public` and `external` TypeFixed
`public` functions that are never called by the contract could be declared as `external`. `external` functions are more efficient than `public` functions.
LowNo Upper Limits for FeesFixed
According to the calculation of fees in the function `_transfer()`, the fee rate must be less than 100%. And it's better to set a reasonable upper bound for the fee rates like 10%, 5% etc to be transparent and reliable to users.
