Boolean constants can be used directly and do not need to be compared to true or false. ```solidity=652 if (_lpStatus == false) { ```
Open the reportThe linked `public` functions that are never called by the contract could be declared as `external`. `external` functions are more efficient than `public` functions.
Open the reportThe **require** can be used to check for conditions and throw an exception if the condition is not met. It is better to provide a string message containing details about the error that will be passed back to the caller.
Open the reportDuring `OLY` token transfers, a fee is applied to the transfer. This fee structure depends on whether the transaction is buying/selling from a liquidity pool, or a regular token transfer. The three percentage fees taken from any transfer type are `dividend`, `funds` and `invite`. Their percentages are dictated by the `_owner` authorized function `setParams()`. If the percentage sum of these fees exceed 100% (or in other words, if the amount of fees is greater than the amount of tokens being transferred) then the function `_transferFee()` will lead to a revert, and as a consequence the `OLY` token cannot be transferred. ```solidity=695 uint256 _amount1 = amount.mul(_args.dividend).div(100); uint256 _amount2 = amount.mul(_args.funds).div(100); uint256 _amount3 = amount.mul(_args.invite).div(100); uint256 _amount4 = amount.sub(_amount1.add(_amount2).add(_amount3)); //This will revert if amount < (_amount1 + _amount2 + _amount3) ```
Open the reportAddresses should be checked before assignment or external call to make sure they are not zero addresses.
Open the reportThe linked mappings are never used in the codebase. --- Variables `_idoers` and `_shares` in contract `OLY` is never used. ```solidity=429 mapping(address => uint256) internal _idoers; mapping(address => uint256) internal _shares; ```
