PhoenixChain, Is a next-gen unique chain, bringing the real value with real utility on cryptocurrency. Providing for the other token that would join on our unique and next-gen Ecosystem The main idea behind PhoenixChain is to provide Decentralized Finance network, which operates on the Binance Smart Chain (BEP-20). The path forward for PCN is not just a token but we evolve into a coin, Building our independent own ecosystems.

Reentrancy in PhoenixChain.claimBNBReward() (#1158-1179):
External calls:
- (success) = address(charityAddress).call{value: charityamount}() (#1167)
State variables written after the call(s):
- nextAvailableClaimDate[msg.sender] = block.timestamp + getRewardCycleBlock() (#1174)
Apply the check-effects-interactions pattern.

PhoenixChain.claimBNBReward() (#1158-1179) contains a tautology or contradiction:
- require(bool,string)(balanceOf(msg.sender) >= 0,Error: must own PhoenixChain to claim reward) (#1160)
Fix the incorrect comparison by changing the value type or the comparison.

PhoenixChain.migrateBnb(address,uint256)._newadd (#1301) lacks a zero-check on :
- (success) = address(_newadd).call{value: amount}() (#1302)
Check that the address is not zero.

- pancakeRouter.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner,block.timestamp + 360) (#1381-1388)
State variables written after the call(s):
- _approve(sender,_msgSender(),_allowances[sender][_msgSender()].sub(amount,BEP20: transfer amount exceeds allowance)) (#832)
- _allowances[owner][spender] = amount (#1028)
Apply the check-effects-interactions pattern.

PhoenixChain._addLiquidity(address,uint256,uint256) (#1375-1389) ignores return value by pancakeRouter.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner,block.timestamp + 360) (#1381-1388)
Ensure that all the return values of the function calls are used.

PhoenixChain._addLiquidity(address,uint256,uint256).owner (#1376) shadows:
- Ownable.owner() (#387-389) (function)
Rename the local variables that shadow another component.

PhoenixChain.changethreshHoldTopUpRate(uint256) (#1306-1308) should emit an event for:

PhoenixChain.ensureMaxTxAmount(address,address,uint256,uint256) (#1196-1210) uses timestamp for comparisons
Dangerous comparisons:
- value < disruptiveCoverageFee && block.timestamp >= disruptiveTransferEnabledFrom (#1206)
Avoid relying on block.timestamp.

Address._functionCallWithValue(address,bytes,uint256,string) (#344-365) uses assembly
- INLINE ASM (#357-360)
Do not use evm assembly.
Additional information: link
PhoenixChain.ensureMaxTxAmount(address,address,uint256,uint256) (#1196-1210) compares to a boolean constant:
-_isExcludedFromMaxTx[from] == false && _isExcludedFromMaxTx[to] == false (#1203-1204)
Remove the equality to the boolean constant.

SafeMath.mod(uint256,uint256,string) (#215-218) is never used and should be removed
Remove unused functions.
Additional information: link
PhoenixChain.minTokenNumberToSell (#1132) is set pre-construction with a non-constant function or state variable:
- _tTotal.mul(1).div(10000).div(10)
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-0.6.8 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.

Low level call in PhoenixChain.migrateBnb(address,uint256) (#1301-1304):
- (success) = address(_newadd).call{value: amount}() (#1302)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Variable PhoenixChain._liquidityFee (#1128) is not in mixedCase
Follow the Solidity naming convention.

Redundant expression "this (#227)" inContext (#221-231)
Remove redundant statements if they congest code but offer no value.

Variable PhoenixChain._transferBothExcluded(address,address,uint256).rTransferAmount (#904) is too similar to PhoenixChain._transferFromExcluded(address,address,uint256).tTransferAmount (#1103)
Prevent variables from having similar names.

PhoenixChain.slitherConstructorVariables() (#722-1391) uses literals with too many digits:
- _tTotal = 1000000000000 * 10 ** 9 (#739)
Use: Ether suffix, Time suffix, or The scientific notation
Additional information: link
PhoenixChain.rewardThreshold (#1130) should be constant
Add the constant attributes to state variables that never change.
Additional information: link
_swapETHForTokens(address,uint256) should be declared external:
- PhoenixChain._swapETHForTokens(address,uint256) (#1357-1373)
Use the external attribute for functions never called from the contract.
