Prerequisites

Installation

Following installation, yarn build should be executed once.

Test Deployment

Deploys a set of contracts for testing purposes and can be used on both private and public networks.

For example:

node test_deployment.js deploy --provider http://127.0.0.1:8545 --configPath ./local_config.json --key [TEST_KEY]

node test_deployment.js deploy --provider https://ropsten.infura.io/v3/[PROJECT_ID] --configPath ./ropsten_config.json --ledger

For more info, please run:

node test_deployment.js --help

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:
