address(this) casts escrow contract to address (simply it gets address of escrow contract). _beneficiary.transfer(address(this).balance) transfers all ethers from escrow to beneficiary

here is documentation ethdocs.org/en/latest/contracts-and-transactions/… it can be helpful to read it. contract account is not controlled by private key, it is controlled by code. contract can be created from another contract, the code _escrow = new RefundEscrow(wallet()); does it. you shouldn't have key-pair to do it from code.

| Oct 27, 2018 at 20:09 | comment | added | iappmaker | In RefundEscrow constructor, I am unable to see the place where the escrow account is generated with a key pair. In the constructor, I see that they are checking require(beneficiary != address(0)); and saving the beneficiary. Where the escrow account comes into picture (I mean the key pair generation). Also as per the logic of blockchain I understand that the transactions in a address is possible only when we know the private key. Where it is generated and stored. The Question may me very basic but I would be happy if you could throw some light on it. Thanks in Advance ! | |

1. In a constructor of RefundableCrowdsale contract -> _escrow = new RefundEscrow(wallet()); 2. Contract account doesn't have private key 3. take a look source code of RefundEscrow github.com/OpenZeppelin/openzeppelin-solidity/blob/master/… beneficiary (your wallet) can withdraw funds, when the escrow stopped
