Question

As a contract owner, how do I remove the ethers from the contract address automatically to my wallet?Can I have a function that when the contract receives the ethers from the costumer, it automatically sends the ethers to the owner wallet address?

Answer 1

It is possible to forward ether from receive function to a wallet of your choice.

address owner;
receive() external payable {
    payable(owner).transfer(msg.amount);
}

Just be aware that

• When invoked from another contract receive function has a maximum gas stipend of 2300 gas so transfer will fail. It will work without issues if ether is sent from a non-contract account.
• A contract can receive ether without invoking its receive function, for example by being the recipient of self destructing contract.
• If owner is a contract it has to have a payable receive or fallback function.

The alternative is to have a withdraw function

function withdraw() onlyOwner {
    payable(owner).transfer(address(this).balance);
}
