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
Owner cannot lock any user funds.
Token cannot be burned
There is no burning within the contract without any allowances
Ownership is not renounced
The owner retains significant control, which could potentially be used to modify key contract parameters.
Contract is not upgradeable
The contract does not use proxy patterns or other mechanisms to allow future upgrades. Its behavior is locked in its current state.
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
- The owner can remove limits from the contract.
- The owner can enable trading only once.
- The tax wallet address can swap tokens to ETH manually.
- Any arbitrary address can reduce tax.
Note - This Audit report consists of a security analysis of the Cyrix 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 Cyrix 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
high Issues | 2 findings

#1 high Issue
Unsafe use of tx.origin
Avoid using TX.origin for authorization, another contract can have a method that will call your contract (where the user has some funds for instance) and your contract will authorize that transaction as your address is in tx.origin. It is recommended that use msg.sender for authorization (if another contract calls your contract msg.sender will be the address of the contract and not the address of the user who called the contract.
Pending
#2 high Issue
Missing access control.
The reduceTax function lacks access control, allowing anyone to call it and reduce tax rates arbitrarily, risking economic disruption. Minimal protections, like the _buyCount check and fee limits, are insufficient to prevent misuse. To secure the function, implement access control, such as using Ownable or AccessControl, to restrict changes to authorized users only. Add safeguards like minimum and maximum tax limits and ensure _buyCount is tamper-proof. Emit events for transparency when tax rates are updated. These measures protect the contract’s integrity and ensure tax adjustments align with the intended economic model.

#1 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.
