Donation

A candidate you don’t like is accepting campaign contributions via the smart contract below.

To complete this challenge, steal the candidate’s ether.

pragma solidity ^0.4.21;

contract Donation {
    struct DonationInfo {
        uint256 timestamp;
        uint256 etherAmount;
    }
    DonationInfo[] public donations;

    address public owner;

    function Donation() public payable {
        require(msg.value == 1000000000);
        owner = msg.sender;
    }

    function isComplete() public view returns (bool) {
        return address(this).balance == 0;
    }

    function donate(uint256 etherAmount) public payable {
        // amount is in ether, but msg.value is in wei
        uint256 scale = 10**18 * 1 ether;
        require(msg.value == etherAmount / scale);

        DonationInfo donation;
        donation.timestamp = now;
        donation.etherAmount = etherAmount;

        donations.push(donation);
    }

    function withdraw() public {
        require(msg.sender == owner);
        
        msg.sender.transfer(address(this).balance);
    }
}
