TetherBlack is a revolutionary bsc project run by a team of dedicated and honest individuals. At TetherBlack we strive for safety, reliability and security which we plan on bringing into the bsc space. This will be the first of many projects of our ecosystem and will be heavily funded by taxes of the other projects. Determined project owners can purchase franchises of our ecosystem with ease and in a secure way in which they will carry our name to success.

TetherBlack.addLiquidity(uint256,uint256) (#797-810) sends eth to arbitrary user
Dangerous calls:
- dexRouter.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,burnAddress,block.timestamp) (#802-809)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.
TetherBlack.setLpPair(address,bool) (#550-560) compares to a boolean constant:
-enabled == false (#551)
Remove the equality to the boolean constant.
Additional information: link
Context._msgData() (#9-12) is never used and should be removed
Remove unused functions.
Additional information: link
TetherBlack.swapAmount (#391) is set pre-construction with a non-constant function or state variable:
- (_tTotal * 5) / 1000
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

solc-0.8.9 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Variable TetherBlack._hasLiqBeenAdded (#394) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#10)" inContext (#4-13)
Remove redundant statements if they congest code but offer no value.

TetherBlack.swapAndLiquify(uint256) (#747-777) performs a multiplication on the result of a division:
-toEcosystem = (contractTokenBalance * _ecosystemRatio) / (totalFee) (#753)
-_ecosystemWallet.transfer((fromSwap * toEcosystem) / toSwapForEth) (#775)
Consider ordering multiplication before division.

TetherBlack.addLiquidity(uint256,uint256) (#797-810) ignores return value by dexRouter.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,burnAddress,block.timestamp) (#802-809)
Ensure that all the return values of the function calls are used.
Additional information: link
TetherBlack.setSwapSettings(uint256,uint256,uint256,uint256) (#629-632) should emit an event for:
- swapThreshold = (_tTotal * thresholdPercent) / thresholdDivisor (#630)
- swapAmount = (_tTotal * amountPercent) / amountDivisor (#631)
Emit an event for critical parameter changes.

TetherBlack.setWallets(address,address).newEcosystemWallet (#634) lacks a zero-check on :
- _ecosystemWallet = address(newEcosystemWallet) (#636)
Check that the address is not zero.

TetherBlack.setLpPair(address,bool) (#550-560) uses timestamp for comparisons
Dangerous comparisons:

Avoid relying on block.timestamp.
