Externally Owned Account use Contrast account to transfer ether

Question

can I use a Externally Owned Account to call contract account function to transfer ether to other Externally Owned Accounts, and the ether is from contract account.

Answer 1

Yes you can and it's very simple to do.

Something like this:

pragma solidity ^0.5.1;

contract MyContr {
    function transfer(address payable receiver, uint amount) public {
        require(address(this).balance >= amount);
        receiver.transfer(amount);
    }
}

Then you deploy the contract, get its ABI and address, input those into a wallet software of your choice and send a transaction to the transfer function of the contract with the required parameters.

You should of course add all sort of security checks (not everyone should be allowed to do the transfer).
