MintableToken

Prerequesites

To be able to download the required packages you need to have node.js installed. If you haven't installed it already go to https://nodejs.org/en/download/ to download the newest version for your os.

Init npm if it's not already initialized

npm init -y

Install truffle globally if it's not already installed

npm install -g truffle

Verify that truffle is installed

D:\Git\MintableToken>truffle v

...
Truffle v5.1.45 (core: 5.1.45)
Solidity v0.5.16 (solc-js)
Node v10.16.3
Web3.js v1.2.1

To resolve the openzeppelin dependencies we'll need to install the dependencies using

npm install @openzeppelin/[email protected]

As we will use truffle hardware wallet to deploy to public networks we will also need to install this dependency using

npm install @truffle/hdwallet-provider

For the deployment we will use then openzeppelin-cli. To install it run

npm install @openzeppelin/cli

Finally run npm update within the workdir

npm update

Deployment

Deploying to local (Ganache) Network

For testing local deployments we are using Ganache. To install it run

npm install -g ganache-cli

Start Ganache process

ganache-cli

Identify that the process is running by seeing the automatically created wallets and private keys and having the "Listening on Listening on 127.0.0.1:8545" line at the end

Once the ganache process is up and running, open up a new console and deploy the contract

npx oz deploy

The contracts will be automatically compiled

Deploying to public Networks

In order to be able to deploy to one of the public networks we will need to sign all transactions locally. @truffle/hdwallet-provider is embedded to do this,but we will need to create a file "secrets.json"

{
  "mnemonic": "pioneer tent curve wild ...",
  "projectId": "305c13705054a8d918ad77549e402c72"
}

This file inherits your mnemonic and and the infura projectid which is required to deploy the contracts the desired public network. So you will need to register an account at https://infura.io/register and create a new project. Afterwards you will find your projectid within the projects settings page.

After you've created the secrets.json run npx oz deploy and follow the wizard through the setup steps and choose your desired network

PS D:\Git\MintableToken> npx oz deploy
