Privileged Functions / Owner Capabilities

1️⃣ The contract contains the following privileged functions that are restricted by onlyOwner modifier:

excludeFromFee(address account)
includeInFee(address account)

2️⃣️⃣ The owner can set maxTxAmount which is the number of % of the total supply that can be swapped in one transaction.

function setMaxTxPercent(uint256 maxTxPercent, uint256 maxTxDecimals) external onlyOwner()


Issue #1 | 🔍 Location setMaxTxPercent |Owner Capabilities| 🔴 High Severity | Status: Fixed ✅


The owner of the contract can make the token untradable. By calling setMaxTxPercent(0) or by setting _taxFee variable of _liquidityFee variable to 1000.


Our recommendation is to have a minimum or at least maximum limit for the setLiquidityFeePercent, and setTaxFeePercent setter function. Add a require statement that would restrict setting _maxTxAmount to 0.

The team fixed this issue in their new contract:

function setMaxTxPercent(uint256 maxTxPercent) external onlyOwner() {
require(maxTxPercent!=0, "can't set to zero");
_maxTxAmount = _tTotal.mul(maxTxPercent).div(
