I'm reviewing the crowdsale example and I have a small question. When the crowdsale is open, somehow the contract "holds" ether, right? As it is receiving ether using the () function and not sending it anywhere

hey, guys, I'm trying to use the code example of crowdsale and get an error: Unused local variable
contract token { function transfer(address receiver, uint amount){ } }

What can be a problem?

Hi, new to the forum and not sure if this is the place to ask related question, if not please point me to right direction.

Is this possible that we write a smart contract which does a transaction? Like one party selling something and other is buying, now there is a bit trust issue as who will transfer first. Is this possible that smart contract acts a middle man and once both transfer money and goods/ services to etehreum than there transfer them to respective parties?

If yes will I need to pay some fee like transaction fee to ethereum?
If I want to develop a mobile app which speaks to smart contracts how can I do that? do we have some apis or sdks for that?
Thanks
