Project Phases

Phase 1
  Implement the ERC20 smart contract in Remix browser IDE https://remix.ethereum.org
  Test the contract functions

Phase 2
  - Clone the starter project
    git clone https://github.com/zastrin/boston_token
    npm install
  - Copy the token contract code in to the starter project contracts/ERC20Token.sol
  - Compile by running "truffle compile" - If it just hangs, ctrl+c to kill it.
  - Get some Ropsten test Ether from faucet: faucet.metamask.io
  - Deploy to ropsten test network
    In truffle.js, update the mnemonic to use your metamask seed
    truffle migrate --network ropsten

Phase 3
  - Check your token balance from command line
    In your starter project, run truffle console --network ropsten, it gives you a Javascript environment injected with other tools required to interact with blockchain
    > ERC20Token.deployed().then(function(f) {f.balanceOf.call('your address').then(function(f) {console.log(f)})})
  - Run: "npm run dev", it will start the frontend server at localhost:8080
  - Update the frontend to display token name, symbol, price and balance
    You have to make changes in app/javascript/app.js

Phase 4
  - Register your token with the TokenMaster Contract. If successfully registered, your token address will be visible on the projector
    You can get your token address in truffle console by running this: ERC20Token.deployed().then(function(f) {console.log(f.address)})
    We have already deployed the TokenMaster Contract. You just have to trigger a call. Hint: TokenMaster.deployed().then(....). You can refer to the TokenMaster contract register function here: https://github.com/levelkdev/training-contracts/blob/master/contracts/TokenMaster.sol

Phase 5
  - TAs will purchase your token and in return send Class Tokens.
  - Check your class token balance in truffle console
    Hint: ERC20Token.at('0x5ac140c32dd3c32dc78c57f75262c2210bfb6d58') gives you an instance of class token

Phase 6
  - Tip the TAs using class token. Again refer to TokenMaster contract file for tip function details. To tip, you have to first approve say 100 tokens to transfer to address '0x1efeca31b7a122fc5a3a822885f5d00c39b6cd01'. Then call the tip function
  - Display in your frontend your Class Tokens balance

Phase 7
  - Bonus 1: Implement a function in your token contract for anyone to purchase your tokens
  - Bonus 2: Implement the frontend to send your tokens to any address
