The protocol does not support tokens with precision greater than 18 decimals

Bauer

Summary

Tokens with precision greater than 18 decimals will encounter errors when calling convertTokenAmountToUd60x18() for conversion.

Vulnerability Details

The function convertTokenAmountToUd60x18() is used to convert a token amount to an 18-decimal format. However, if the token has a precision greater than 18 decimals, this conversion can result in an error. This issue arises because the function might not accurately handle the extra decimals, leading to incorrect calculations or potential loss of precision.

function convertTokenAmountToUd60x18(Data storage self, uint256 amount) internal view returns (UD60x18) {
if (Constants.SYSTEM_DECIMALS == self.decimals) {
return ud60x18(amount);
}
return ud60x18(amount * 10 ** (Constants.SYSTEM_DECIMALS - self.decimals));
}

Impact

The protocol will encounter errors.
