solidity selfdestruct合约销毁

solidity selfdestruct合约销毁

1、部署合约，附带value

2、获取合约地址的eth余额，余额为第一步附带的value

3、调用方法killSelf，进行合约的销毁，并把剩余的ETH转给receiver

contract Destroy {

    constructor() payable {
        owner = msg.sender;
    }

    event Receive(address indexed sender, uint256 amount, string data);

    receive() external payable {
        emit Receive(msg.sender, msg.value, "Receive Success");
    }

    function killSelf(address receiver) public {
        require(msg.sender == owner, "Only owner can call this function");

        // // 调用selfdestruct销毁合约，并把剩余的ETH转给receiver
        selfdestruct(payable(receiver));
    }

    // 获取合约地址的eth余额
    function getBalance() public view returns (uint256) {
        return address(this).balance;
    }
}
