Your “Token Address” on the Ropsten Network

Per the response found on the Udacity Knowledgebase, I have deployed to the Ropsten Network because I can't get enough ETH on the Rinkeby network.

ND1309 C2 Ethereum Smart Contracts, Tokens and Dapps - Project Starter

PROJECT: Decentralized Star Notary Service Project - For this project, you will create a DApp by adding functionality with your smart contract and deploy it on the public testnet.

ToDo

This Starter Code has already implemented the functionalities you implemented in the StarNotary (Version 2) exercise, and have comments in all the files you need to implement your tasks.

Dependencies

For this project, you will need to have:

Node and NPM installed - NPM is distributed with Node.js

# Check Node version
node -v
# Check NPM version
npm -v

Truffle v5.X.X - A development framework for Ethereum.

# Unsinstall any previous version
npm uninstall -g truffle
# Install
npm install -g truffle
# Specify a particular version
npm install -g truffle@5.0.2
# Verify the version
truffle version

Metamask: 5.3.1 - If you need to update Metamask just delete your Metamask extension and install it again.
Ganache - Make sure that your Ganache and Truffle configuration file have the same port.
Other mandatory packages:

cd app
# install packages
npm install --save  openzeppelin-solidity@2.3
npm install --save  truffle-hdwallet-provider@1.0.17
npm install webpack-dev-server -g
npm install web3

Run the application

Clean the frontend

cd app
# Remove the node_modules
# remove packages
rm -rf node_modules
# clean cache
npm cache clean
rm package-lock.json
# initialize npm (you can accept defaults)
npm init
# install all modules listed as dependencies in package.json
npm install

Start Truffle by running

# For starting the development console
truffle develop
# truffle console

# For compiling the contract, inside the development console, run:
compile

# For migrating the contract to the locally running Ethereum network, inside the development console
migrate --reset

# For running unit tests the contract, inside the development console, run:
test

Frontend - Once you are ready to start your frontend, run the following from the app folder:

cd app
npm run dev

Important

When you will add a new Rinkeyby Test Network in your Metamask client, you will have to provide:

Network Name	New RPC URL	Chain ID
Private Network 1	`http://127.0.0.1:9545/`	1337

The chain ID above can be fetched by:

cd app
node index.js

Troubleshoot

Error 1

'webpack-dev-server' is not recognized as an internal or external command

Solution:

Delete the node_modules folder, the one within the /app folder
Execute npm install command from the /app folder

After a long install, everything will work just fine!

Error 2

ParserError: Source file requires different compiler version.
Error: Truffle is currently using solc 0.5.16, but one or more of your contracts specify "pragma solidity >=0.X.X <0.X.X".

Solution: In such a case, ensure the following in truffle-config.js:

// Configure your compilers
compilers: {
  solc: {
    version: "0.5.16", // <- Use this
    // docker: true,
    // ...
