PYX [PYXIS (pyxis.network)] Token

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.
