Prerequisites

Installation

Following installation, npm run build should be executed once.

Test Deployment

Deploys a set of contracts for testing purpose; can be used on both private and public networks:

node test_deployment.js
    Configuration file name
    Ethereum node address
    Account private key

The configuration file is updated during the process, in order to allow resuming a prematurely-terminated execution.

Here is an example of the initial configuration file which should be provided to the process:
