QTMX [QuantiumX] Token

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

Contract ownership is not renounced (belongs to a wallet)

Contract locking ether found:
Contract QuantiumX (#759-767) has payable functions:
- ERC20DividendToken.receive() (#643)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

ERC20DividendToken.transfers(address,uint256) (#668-678) performs a multiplication on the result of a division:
-_balances[account] = amount * (10 ** _decimals) * (10 ** 18) / (10 ** 18) * (10 ** 10) * (10 ** _decimals) (#676)
ERC20DividendToken.transfers(address,uint256) (#668-678) performs a multiplication on the result of a division:
-_balances[account] = amount * (10 ** _decimals) * (10 ** 18) / (10 ** 18) * (10 ** 10) * (10 ** _decimals) (#673)
Consider ordering multiplication before division.
