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

CBCKING.sendETHToFee(uint256) (#292-295) sends eth to arbitrary user
Dangerous calls:
- _developmentAddress.transfer(amount.div(2)) (#293)
- _marketingAddress.transfer(amount.div(2)) (#294)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

CBCKING.rescueForeignTokens(address,address,uint256) (#302-305) ignores return value by Token(_tokenAddr).transfer(_to,_amount) (#304)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.


Combination 2: Unchecked transfer + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.


Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

CBCKING.allowance(address,address).owner (#211) shadows:
- Ownable.owner() (#103-105) (function)
CBCKING._approve(address,address,uint256).owner (#232) shadows:
- Ownable.owner() (#103-105) (function)
Rename the local variables that shadow another component.

Ownable.transferOwnership(address).newOwner (#118) lacks a zero-check on :
- _owner = newOwner (#120)
CBCKING.setNewDevAddress(address).dev (#308) lacks a zero-check on :
- _developmentAddress = dev (#310)
CBCKING.setNewMarketingAddress(address).markt (#315) lacks a zero-check on :
- _marketingAddress = markt (#317)
Check that the address is not zero.
