title: Smart contract in blockchain ethereum
body: <p>I'm trying to deploy a smart contract using testrpc &amp; truffle. My smart contract is as simple as HelloWorld. Contract is successfully deployed with 0xfd52dd6fd4002b86ccbd3ae7c7a3e1a9d16c3648 this address. The only point that I don't understand is, a contract should involve two parties. When I run this command <code>HelloWorld.deployed()</code>, I'm only getting <strong>from</strong> address. I want to have both parameters i.e <strong>FROM &amp; TO</strong>. My question is how to include <strong>TO</strong>  parameter while signing a contract in ethereum?</p>
