Deploying a Contract Using Truffle

Introduction

Truffle is a widely used development environment and testing framework for Ethereum smart contracts. In this tutorial, we will show by example how to use Truffle with the Aurora Testnet.

This tutorial assumes that you are familiar with Truffle and the non-fungible tokens (NFT) concept. For more details about the non-fungible token standard, please refer to the ERC-721 Non-Fungible Token Standard specification.

Installing Prerequisites

This tutorial assumes that you have Node.js 12+ and Yarn. Please refer to the Yarn installation how-to if you don't yet have the yarn command installed locally.

To install the prerequisite packages, clone the examples repository and then run yarn:

Install Truffle

npm install -g truffle 

Install dependencies

git clone https://github.com/faisalramdan17/flutter-aurorafactory.git

cd flutter-aurorafactory

yarn 

Connecting Truffle to Aurora

Export your MNEMONIC as follows:

export MNEMONIC='YOUR MNEMONIC HERE'

Now in truffle-config.js, you will need to change the from address as shown below in the aurora network section:

...
aurora: {
    provider: () => setupWallet('https://testnet.aurora.dev'),
    network_id: 0x4e454153,
    gas: 10000000,
    from: process.env.OWNER_ADDRESS // ADD YOURS AT .ENV BY RENAMING .ENV-EXAMPLE FILE
},

The truffle-config.js configuration will pick up your MNEMONIC environment variable and recover the address that will be used for sending and signing transactions on the Aurora network.

Deploying the Contract

To deploy the ERC20Factory contract, you can run the yarn command as follows:

yarn deploy:aurora
