Setup

Global dependencies

• Ethereumjs-Testrpc Ethereum testing node

$ npm install -g truffle ethereumjs-testrpc

Local dependencies

In same the directory with package.json install project dependencies

$ npm install

Edit configuration

There two configuration files

• config.js: Contains general configuration parameters like ethereum node, port

• local_config.json: Used to store values that cannot be commited like wallet seeds.

  For each one two parameters: seed, and address.

  {
    "submitter": {
      "seed": "...",
      "address": "..."
    }
  }

  There's a local_config.json.example that can be used as template.

  New wallet seeds can be generated with node src/tools/manageAccounts.js generate.
