PYXIS Network is a decentralized finance staking platform on Binance Smart Chain.
PYX Token is used for:
Staking. People can lock the tokens for an amount of time and earn when the stake is matured.
DApp charting tool. To unlock features on the dexchart.com for portfolio management and token price charting.
PYXIS Network includes:
BNB Staking People can use BNB to stake and earn.
PYX Staking People can use PYX to stake and earn.
Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)
Contract name (PYXIS (pyxis.network)) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.
Reentrancy in PYXToken._transfer(address,address,uint256) (contracts/PYXToken.sol#206-259):
External calls:
- PYX_STAKING.contractAddPYXToPool(feesAmount.div(2)) (contracts/PYXToken.sol#242)
State variables written after the call(s):
- balanceOf[recipient] = balanceOf[recipient].add(transferAmount) (contracts/PYXToken.sol#244)
Apply the check-effects-interactions pattern.

PYXToken.removeSenderContractAddress(address) (contracts/PYXToken.sol#185-191) ignores return value by senderContractAddresses.remove(account) (contracts/PYXToken.sol#189)
Ensure that all the return values of the function calls are used.

SafeMath.mod(uint256,uint256,string) (@openzeppelin/contracts/math/SafeMath.sol#155-158) is never used and should be removed
Remove unused functions.
Additional information: link
Pragma version^0.6.0 (contracts/interfaces/IPYXToken.sol#3) 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.

Low level call in Address.functionStaticCall(address,bytes,string) (@openzeppelin/contracts/utils/Address.sol#139-145):
- (success,returndata) = target.staticcall(data) (@openzeppelin/contracts/utils/Address.sol#143)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Redundant expression "this (@openzeppelin/contracts/GSN/Context.sol#21)" inContext (@openzeppelin/contracts/GSN/Context.sol#15-24)
Remove redundant statements if they congest code but offer no value.

Variable PYXToken.PYX_STAKING (contracts/PYXToken.sol#51) is too similar to PYXToken.init(uint256,uint256,address,address,address[])._pyxStaking (contracts/PYXToken.sol#98)
Prevent variables from having similar names.

decreaseAllowance(address,uint256) should be declared external:
- PYXToken.decreaseAllowance(address,uint256) (contracts/PYXToken.sol#313-327)
Use the external attribute for functions never called from the contract.
