Critical`BURNER_ROLE` Can Burn Any AssetOSIS · CertiK · 5 Dec 2022Fixed
This functionality is very dangerous not only can it destroy the protocol. It can easily one side the pool if this is on any DEX. For Example: Token A is worth 1000 of token B The pool has 1,000 (token A) and 100,0000 (token B) respectively. The token price can be instantly changed if this function is called to burn either side.
Open the reportMedium`mint()` and `mintAirdrop()` Can Mint More than `OSIS · CertiK · 5 Dec 2022Fixed
When a user sees `maxSupply()` they might think they supply cannot grow larger. However, the token can be minted past the `MAXIMUMSUPPLY` because there is no check on the mint. This is misleading and the design of the system should be rethought to ensure this is intended or not. This is also misleading because in the constructor the `MAXIMUMSUPPLY` is minted, but a team wallet can mint more than this. Moreover, even if this is fixed this can be used in conjunction with the burn function to burn another users tokens to mint more and sell.
Open the reportMediumWithdraw Function Does Not WorkOSIS · CertiK · 5 Dec 2022Fixed
The `withdraw()` function does not have a fallback function to accept funds, so it cannot accept any native token balances. We understand this is to retrieve lost funds, but it is not possible to deposit native assets. For example: Bob tries to send ether to this address. It will fail because it does not have any functionality to receive it.
Open the reportLowContract Name Different from FileOSIS · CertiK · 5 Dec 2022Fixed
We do not expect contract names and file names to be the same or do we want this to happen. We are pointing this out for consistency because the file name is `MGBTokenV1.sol`, and the contract is `MGBTokenV2`.
Open the reportLowMissing Error MessagesOSIS · CertiK · 5 Dec 2022Fixed
The `require()` statements should provide a description of the condition not met.
Open the reportLowMissing OpenZeppelin ImportOSIS · CertiK · 5 Dec 2022Fixed
This needs the `Ownable` import from OpenZeppelin to compile properly.
Open the reportLowOnly Owner Functions are not all togetherOSIS · CertiK · 5 Dec 2022Fixed
If this comment is dictating that all `onlyOwner` functions are below, then the `mint()` function should be included in this section for clarity.
Open the reportLowPotential Redundant Mathematical OperationOSIS · CertiK · 5 Dec 2022Fixed
The linked statement redundantly divides by 100. This could be avoided by setting rewards to single digits.
Open the reportLowRedundant VariableOSIS · CertiK · 5 Dec 2022Fixed
The following variables are doing the same thing and one can be used instead. ```Solidity uint256 public maxSupply = 10000; uint256 public maxMintAmount = 10000; ```
Open the reportLowRedundant Variable InitializationOSIS · CertiK · 5 Dec 2022Fixed
The variable `paused` is already set to false by default in Solidity.
