Possible Security Problem in your Contract/用戶金錢的安全風險

[ytrezq]

Hi,

What’s the purpose of checking that codsize of msg.sender==0 in your contract’s code?
Please bear in mind there are ways for an Ethereum address to have codesize of 0 and still be an existing contract.

In order to assist you faster in free auditing, and see if this is a problem and look at other security issues (if you need to upgrade to a new contract better fix all fix all issues instead of only one), may you share the code of at list either 0xf8A4d3a0B5859a24cd1320BA014ab17F623612e2 or 0xed6b0dC3AA8dE5908aB857a70Cb2Ff657d9b6C5d please?

You don’t need to do it publicly on GitHub or etherscan which means you can share it privately with me.
