Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)


Contract ownership is not renounced (belongs to a wallet)

CoinToken.allowance(address,address).owner (#675) shadows:
- Ownable.owner() (#381-383) (function)
CoinToken._approve(address,address,uint256).owner (#871) shadows:
- Ownable.owner() (#381-383) (function)
Rename the local variables that shadow another component.

Token is deployed only at one blockchain

Contract has 6% buy tax and 5% sell tax.
Taxes are low but contract ownership is not renounced. Token has a high risk of becoming a honeypot.
