首先你需要在智能合约中定义这个函数 function () payable public {}，这时这个合约地址就可以接收ETH了。
测试方法，向合约地址发送ETH即可。
pragma solidity ^0.4.24;
contract NetkillerCashier {
function () payable public {}
function claim() public {
selfdestruct(msg.sender);
}
}

Contract 0x0896827f5e3d2683763321bdf780bde1824f6137 TRANSFER 0.03 Ether from 0x0896827f5e3d2683763321bdf780bde1824f6137 to 0x22c57f0537414fd95b9f0f08f1e51d8b96f14029 SELF-DESTRUCT Contract 0x0896827f5e3d2683763321bdf780bde1824f6137

本合约只收取 1 ETH 多余 ETH 将退给用户
pragma solidity ^0.4.24;
// Author: netkiller@msn.com
// Website: http://www.netkiller.cn
contract Refund {
address owner = 0x0;
uint256 ticket = 1 ether;
constructor() public payable {
owner = msg.sender;
}
function () public payable {
require(msg.value >= ticket);
if (msg.value > ticket) {
uint refundFee = msg.value - ticket;
msg.sender.transfer(refundFee);
}
}
}
合约收到ETH后自动转到 owner 账号中。
pragma solidity ^0.4.24;
contract NetkillerCashier {
address public owner;
constructor() public payable {
owner = msg.sender;
}
function () payable public {
owner.transfer(msg.value);
}
}
pragma solidity ^0.4.24;
contract NetkillerCashier {
address public owner;
uint public amount;
modifier onlyOwner {
require(msg.sender == owner);
_;
}
constructor() public {
owner = msg.sender;
}
function () public payable {
amount += msg.value;
}
function transferOwnership(address newOwner) onlyOwner public {
if (newOwner != address(0)) {
owner = newOwner;
}
}
function withdraw() onlyOwner public {
msg.sender.transfer(amount);
amount = 0;
}
}
function transferOwnership(address newOwner) 可以修改指定账号提取 ETH function withdraw() 提取 ETH 的函数
