contract PiggyBank { function() public payable { } }
but nobody can crack it
contract PiggyBank { function() public payable { } function Crack () public { selfdestruct(msg.sender); } }
but anybody can crack it and take the money
contract PiggyBank { address owner; function PiggyBank () { owner = msg.sender; } function() public payable { } function Crack () public { selfdestruct(owner); } }
but anybody can crack it
contract PiggyBank { address owner; function PiggyBank () { owner = msg.sender; } function() public payable { } function Crack () public { require(msg.sender == owner); selfdestruct(owner); } }
only the owner can crack it
