Summary and Final Words
No crucial issues found
The contract does not contain issues of high or medium criticality. This means that no known vulnerabilities were found in the source code.
Contract owner cannot mint
It is not possible to mint new tokens.
Contract owner cannot blacklist addresses.
It is not possible to lock user funds by blacklisting addresses.
Contract owner cannot set high fees
The fees, if applicable, can be a maximum of 25% or lower. The contract can therefore not be locked. Please take a look in the comment section for more details.
Contract cannot be locked

Scope of Work
This audit encompasses the evaluation of the files listed below, each verified with a SHA-1 Hash. The team referenced above has provided the necessary files for assessment.
The auditing process consists of the following systematic steps:
- Specification Review: Analyze the provided specifications, source code, and instructions to fully understand the smart contract's size, scope, and functionality.
- Manual Code Examination: Conduct a thorough line-by-line review of the source code to identify potential vulnerabilities and areas for improvement.
- Specification Alignment: Ensure that the code accurately implements the provided specifications and intended functionalities.
- Test Coverage Assessment: Evaluate the extent and effectiveness of test cases in covering the codebase, identifying any gaps in testing.
- Symbolic Execution: Analyze the smart contract to determine how various inputs affect execution paths, identifying potential edge cases and vulnerabilities.
- Best Practices Evaluation: Assess the smart contracts against established industry and academic best practices to enhance efficiency, maintainability, and security.
- Actionable Recommendations: Provide detailed, specific, and actionable steps to secure and optimize the smart contracts.
A file with a different Hash has been intentionally or otherwise modified after the security review. A different Hash may indicate a changed condition or potential vulnerability that was not within the scope of this review.
Final Words
The following provides a concise summary of the audit report, accompanied by insightful comments from the auditor. This overview captures the key findings and observations, offering valuable context and clarity.
Ownership Privileges
- There are no ownership privileges in the contract.
Note - This Audit report consists of a security analysis of the Catbee Token smart contract. This analysis did not include functional testing (or unit testing) of the contract’s logic. Moreover, we only audited one token contract for the Catbee team. Other contracts associated with the project were not audited by our team. We recommend investors do their own research before investing.

Findings and Audit result
medium Issues | 2 findings
Resolved
#1 medium Issue
The owner can mint tokens.
The _mint function allows the owner to mint unlimited tokens, which can devalue the token and harm user trust. This centralizes control, posing a significant security risk. To mitigate this, impose a hard cap on the total supply, limiting the number of tokens that can be minted. Additionally, introduce minting limits or governance approval to prevent unchecked minting. Transparency can be enhanced by emitting events for every minting operation. For example, setting a MAX_SUPPLY ensures the total supply doesn’t exceed a set limit. This improves token stability, protects users, and reduces the risk of inflation and abuse.
Resolved
#2 medium Issue
The owner can pause the token transfer
The contract contains functionality in which the contract owner can lock the token transfer for an indefinite period of time, which is not recommended as this can lock the user's functions, and the user will not be able to transfer any tokens. There should be a check so that the token transfer should not be locked for an indefinite period of time.

#1 low Issue
Floating pragma solidity version.
Adding the constant version of solidity is recommended, as this prevents the unintentional deployment of a contract with an outdated compiler that contains unresolved bugs.
Pending
#2 low Issue
Remove safemath library
The compiler version above 0.8.0 has the ability to control arithmetic overflow/underflow. It is recommended to remove the unwanted code in order to avoid high gas fees.
Pending
#3 low Issue
Local variable shadowing
Rename the local variables that shadow another component.

Function that are not used (Dead code).
It is recommended to remove the unused code from the contract.
