Deployed Contract Address – How to Get Deployed Contract Address Using Truffle 3.x Console

The easiest way would be to store the owner/creator of the contract in a state variable on deployment.

pragma solidity ^0.4.8;
contract myContract  {

    address public owner;

    function myContract() {
        owner = msg.sender;
    }
}

You could manually modify the contract file in the build directory to include the address, but it will get overwritten eventually, so it's not a good way to do this.

Moreover deployed() is meant to be used in the sense of a singleton. If your contract is not a singleton then you shouldn't query it via deployed().

If you have the following constellation: contract A (singleton) instantiates contract B then you can store the reference(s) to B in A and query it from JavaScript.

Example

contract A {
    B[] public arrayOfBs;
    function create() returns (B) {
        B b = new B();
        arrayOfBs.push(b);
        return b;
    }
}

deployer.deploy(A);
...
A.deployed()
    .then(a => {return a.arrayOfBs(idx)})
    .then(bAddr => {return B.at(b)})
    .then(b => {b.showMeTheMoney()})

If B should be a singleton, then you need to change your migration script and deploy it like this.

deployer.deploy(A); 
deployer.deploy(B);

Then you'll be able to query it via B.deployed().
