Reentrancy in SafeNFTGems._transfer(address,address,uint256) (#985-1043):
External calls:
- swapAndLiquify(contractTokenBalance) (#1024)

- pcsV2Router.swapExactTokensForETHSupportingFeeOnTransferTokens(tokenAmount,0,path,address(this),block.timestamp) (#1208-1214)
External calls sending eth:
- swapAndLiquify(contractTokenBalance) (#1024)
- pcsV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1222-1229)
State variables written after the call(s):
- _transferStandard(sender,recipient,amount) (#1040)
- _rOwned[address(this)] = _rOwned[address(this)].add(rLiquidity) (#1173)
- _rOwned[sender] = _rOwned[sender].sub(rAmount) (#1058)

- _transferStandard(sender,recipient,amount) (#1040)
- _rTotal = _rTotal.sub(rFee) (#1066)
Apply the check-effects-interactions pattern.

SafeNFTGems._excluded (#752) is never initialized. It is used in:
- SafeNFTGems._getCurrentSupply() (#1155-1168)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

SafeNFTGems._getTValues(uint256) (#1112-1127) performs a multiplication on the result of a division:
-tLiquidity = tAmount.div(10 ** 2).mul(_liquidityFee).mul(multiplier) (#1123-1124)
Consider ordering multiplication before division.

SafeNFTGems.addLiquidity(uint256,uint256) (#1217-1230) ignores return value by pcsV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#1222-1229)
Ensure that all the return values of the function calls are used.

SafeNFTGems._approve(address,address,uint256).owner (#959) shadows:
- Ownable.owner() (#341-343) (function)
Rename the local variables that shadow another component.

SafeNFTGems.setLiquidityFeePercent(uint256) (#856-858) should emit an event for:
- _liquidityFee = liquidityFee (#857)
Emit an event for critical parameter changes.

SafeNFTGems._getAntiDumpMultiplier() (#1096-1110) uses timestamp for comparisons
Dangerous comparisons:
- time_since_start < 146 * hour (#1099)
- time_since_start < 218 * hour (#1101)
- time_since_start < 362 * hour (#1103)
- time_since_start < 650 * hour (#1105)
Avoid relying on block.timestamp.

Different versions of Solidity is used:
- Version used: ['>=0.5.0', '>=0.6.2', '^0.6.12']
- ^0.6.12 (#20)
- >=0.6.2 (#386)
- >=0.6.2 (#549)
- >=0.5.0 (#598)
- >=0.5.0 (#632)
Use one Solidity version.

Additional information: link

SafeMath.mod(uint256,uint256,string) (#299-306) is never used and should be removed
Remove unused functions.

Additional information: link

SafeNFTGems._previousLiquidityFee (#762) is set pre-construction with a non-constant function or state variable:
- _liquidityFee
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.

Additional information: link

Pragma version>=0.5.0 (#632) allows old versions
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.

Additional information: link

Variable SafeNFTGems._start_timestamp (#773) is not in mixedCase
Follow the Solidity naming convention.

Additional information: link

Redundant expression "this (#143)" inContext (#133-146)
Remove redundant statements if they congest code but offer no value.

Additional information: link

Variable SafeNFTGems._getValues(uint256).rTransferAmount (#1084) is too similar to SafeNFTGems._getValues(uint256).tTransferAmount (#1082)
Prevent variables from having similar names.

Additional information: link

SafeNFTGems._symbol (#771) should be constant
Add the constant attributes to state variables that never change.

Additional information: link

reflectionFromToken(uint256,bool) should be declared external:
- SafeNFTGems.reflectionFromToken(uint256,bool) (#930-943)
Use the external attribute for functions never called from the contract.
