@sierra1bravo Hey Sierra, in general, you don't want to use "transfer" to move tokens around. Try using the approve+transferfrom combo, see why transfer opens you to security issues here: https://medium.com/coinmonks/ethernaut-lvl-15-naught-coin-walkthrough-how-to-abuse-erc20-tokens-and-bad-icos-6668b856a176. Transfer() was how a lot of ICOs got tokens permanently locked.

Try pasting your code into RemixIDE to get started with the least setup time: http://remix.ethereum.org/

Hi! I'm on Mac, trying to deploy test contract. Found this tut. but it's outdated: https://ethereum.org/token#the-code

using this code, but the "deploy" button doesn't do anything..

contract MyToken {
    /* This creates an array with all balances */
    mapping (address => uint256) public balanceOf;

    /* Initializes contract with initial supply tokens to the creator of the contract */
    constructor (
        uint256 initialSupply
        ) public {
        balanceOf[msg.sender] = initialSupply;              // Give the creator all initial token
    }

}
