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.

Unnecessary safemath library
Since the pragma version is 0.8.19, the overflow/underflow issue is handled by default. Replacing the SafeMath operations with raw mathematical operations is recommended.
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:
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.
