Basic Truffle Ropsten Project

Try running some of the following tasks:

1. Set up Truffle

   npm install -g truffle
   npm install --save truffle-hdwallet-provider

2. Create your contract in ./contracts

3. Deploy your contract

In ./migrations, create a deployment script specifically named 2_deploy_contracts.js

4. Configure Ropsten network and the provider in truffle.js

Make sure to replace mnemonic and API_KEY with your own.

truffle deploy --network ropsten

5. Access your deployed contract

   truffle console --network ropsten

HelloWorld.deployed().then(function(instance){return instance });

6. Finally, invoke contract function and say hello!

   HelloWorld.deployed().then(function(instance){return instance.sayHello()});
