It is the intent of Certicos to conduct a full 3rd party audit of our Solidity Smart Contract after Beta Testing. In lieu of that audit we have conducted a https://www.chaingpt.org Solidity Audit. The following is the date and those results.

 

 

July 5, 2023

Here is the security audit of this smart contract:

1. **Correctness**: The contract does not seem to have any logical errors. The contract has been well-written and follows the standard BEP20 interface.

2. **Structure**: The smart contract uses a modular approach, which is a good practice. The contract uses OpenZeppelin’s Context and Ownable contracts, which are well-audited and trusted in the community.

3. **Access Control**: The contract uses the `onlyOwner` modifier for sensitive functions such as `transferOwnership` and `renounceOwnership`. This is a good practice. It also uses a MinterRole contract to control who can mint tokens, which is also a good practice.

4. **Reentrancy**: The contract does not seem to have any reentrancy issues. The contract does not make any external calls in the middle of a function execution.

5. **Integer Overflow and Underflow**: The contract does not directly handle any arithmetic operations so it is not vulnerable to overflow and underflow attacks.

6. **Unchecked External Calls**: The contract does not make any external calls, so it is not vulnerable to unchecked external call attacks.

7. **Denial of Service**: The contract does not seem to have any potential for Denial of Service attacks.

8. **Timestamp Dependence**: The contract does not rely on timestamps or block numbers, so it is not vulnerable to timestamp manipulation.

9. **Race Conditions**: The contract does not seem to have any potential for race conditions or frontrunning attacks.

Recommendations:

1. **Code Documentation**: The contract could benefit from more inline comments explaining what each function does. This would make the contract easier to read and understand.

2. **Function Visibility**: Ensure that all functions have the appropriate visibility level. For example, helper functions that are not meant to be used externally should be marked as `internal` or `private`.

3. **Test Coverage**: Ensure that the contract has a comprehensive test suite that covers all possible edge cases.

4. **Gas Optimization**: Constantly review the contract for any potential gas optimizations. For example, packing multiple `uint8` or `bool` variables into a single `uint256` can save gas.

5. **Auditing**: Regularly audit the contract for any potential security vulnerabilities. This can be done manually or by using automated tools.

Please note that this audit does not guarantee the absolute security of the contract. It is always recommended to get the contract audited by multiple auditors and to create a comprehensive test suite.
