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 burn function within the contract.

Ownership is renounced

Contract cannot be manipulated by owner functions.

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:

  1. Specification Review: Analyze the provided specifications, source code, and instructions to fully understand the smart contract's size, scope, and functionality.
  2. Manual Code Examination: Conduct a thorough line-by-line review of the source code to identify potential vulnerabilities and areas for improvement.
  3. Specification Alignment: Ensure that the code accurately implements the provided specifications and intended functionalities.
  4. Test Coverage Assessment: Evaluate the extent and effectiveness of test cases in covering the codebase, identifying any gaps in testing.
  5. Symbolic Execution: Analyze the smart contract to determine how various inputs affect execution paths, identifying potential edge cases and vulnerabilities.
  6. Best Practices Evaluation: Assess the smart contracts against established industry and academic best practices to enhance efficiency, maintainability, and security.
  7. 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.


The following _taxWallet is currently set and cannot be renounced: 0x746b95fFe1BD7080169125F12e7d96BC09076E32


Owner privileges

  • The owner can set the fees but only reducing. The _finalBuy and _finalSellTax are set to 4 by default.
  • The owner can remove the limits

TaxWallet privileges

  • The taxWallet can call the manualSwap function

The added liquidity during the opening trade is locked for 12 Months. After it the "_taxWallet" owner can get out the liquidity. Locked: https://app.uncx.network/amm/uni-v2/pair/0x4de01f8b87683d22216f412359c29de634a77367

Information for taxes during the transfer:

  • If the buyCount is below 25%, the "_initialBuyTax" (30%) will be set as fee; otherwise, the "_finalBuyTax" (4%) will be used
  • If the sellCount is below 25%, the "_initialSellTax" (30%) will be set as fee; otherwise, the "_finalSellTax" (4%) will be used

The "onlyOwner" function cannot be called because the owner is renounced (https://etherscan.io/tx/0x544315f727eee0552c31a284a83f2f2133ef03e076b19756a6fedb91c818765d), but the EOA "_taxWallet" can call the "manualSwap" function. In the "manualSwap" function, the "swapAndLiquify" will be called. However, the "_taxWallet" will get the marketing part as ETH, and the liquidity will also be added to the "_taxWallet". Since the "_lpFee" is set to 0, the "addLiquidity" function will never be called.
