All **MC** tokens are sent to the following addresses when deploying the contract: * [0x67a98cc897396e6f51cac5e875f144151598af47: teamAddress_](https://polygonscan.com/address/0x67a98cc897396e6f51cac5e875f144151598af47) * [0x30895f7bacb90e4c421bc8b269e50b37fc00f8c0: foundationAddress_](https://polygonscan.com/address/0x30895f7bacb90e4c421bc8b269e50b37fc00f8c0) * [0xe928340806524e5055d0b73ff52d470acdee2392: ecoAddress_](https://polygonscan.com/address/0xe928340806524e5055d0b73ff52d470acdee2392) * [0xbbdd0e06578259316f1e4fd00aa4f5db7294c632: mineAddress_](https://polygonscan.com/address/0xbbdd0e06578259316f1e4fd00aa4f5db7294c632) This is a potential centralization risk as the aforementioned addresses can distribute **MC** tokens without the consensus of the community. Additionally, these addresses are unknown EOAs, therefore their ownership is uncertain.
Open the reportState variables that never change should be declared as `constant` to save gas. ```solidity=597 address mintAdderss; ``` - `mintAdderss` should be declared `constant`.
Open the reportThe address variable `mintAdderss` is misspelled and should be changed to `mintAddress`.
Open the reportThe `SafeMath` library is used unnecessarily. With Solidity compiler versions 0.8.0 or newer, arithmetic operations will automatically revert in case of integer overflow or underflow. ```solidity=4 library SafeMath { ``` - An implementation of `SafeMath` library is found. --- ```solidity=596 using SafeMath for uint256; ``` - `SafeMath` library is used for `uint256` type in `MC` contract.
Open the report```solidity=596 using SafeMath for uint256; ``` - The library `SafeMath` is declared on a using-for directive in `MC`, but its functionalities are never used.
Open the reportOne or more state variables are never used in the codebase. Variable `mintAdderss` in `MC` is never used. ```solidity=597 address mintAdderss; ```
