The contract owner address is msg.sender. msg.sender is as secure as elliptic curve cryptography. Ethereum uses the same curve and key size as Bitcoin. Everyone knows msg.sender but only possession of the private key will allow someone to sign a transaction as that msg.sender. So, in short even if someone knows the address, they won't have the private key.

if you are transferring the msg.value without storing it,even if if a hacker tries to call the payable function the moment they received the ether, they will receive the ether they sent to the payable function and won't receive any new ether.

I once even saw it happen live, hackers printing tokens and selling them on the GATE.io exchange. I would assume there were lawsuits there. As the developers were accused of faking the ...

In your case, I would research multi-sing wallets. (Wallets that require a multitude of private keys). Therefore if one is stolen, it is still not possible to access the wallet on your own.
Using a single private key in such a case is simply asking for trouble. A single point of failure is never a good thing in a design.

This official Metamask page explains that you need to press "create account" as if you were creating a new account 2, and the resulting account will actually be your existing account 2. Weird, but that's how it is. Also, there seems to be no way to automatically import all the tokens that were there in your old wallet install. So, unless you ...

An example of Flash minting ether is WETH10...Their contract hasn't been audicted, but there are many logic in your background with prevent attack like burning and reverse all transaction if the same ammount of WETH10 don't return to the contract.
