NFTChallenge Introduction

NFTChallenge(NFTC) is an interactive platform where any NFT Project (referred to as third NFTP in the following context) can depoly its contract. On NFTC, any user can join to have fun with any NFTP and eligible users can easily mint.

On NFTC, all NFTPs are integrated with their own NFTs and can be shared with each other. NFTP can also build projects with the help of other existing NFTP. The user's NFTs in each item are not isolated. NFTC encourages user to use the NFTs of other NFTPs to complete the tasks required under a current project.

NFTC makes NFTs truly have circulation value. Besides, it will play a vital role in the metaverse.

Installing Prerequisites

Node.js 12+ and Yarn are required to use this repo. 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 repository and then run yarn:

Install Truffle

npm install -g truffle 

Install dependencies

git clone https://github.com/mircial/NFTChallenge.git

cd NFTChallenge

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: '0x256807C23d5085ad22CC124c00852eE60989fC3E' // CHANGE THIS ADDRESS

},

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

Deploying Contracts

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

yarn deploy:aurora

Interface

A mature front-end (webpack, grunt, etc.) was not used so as to get from scratch as easy as possible.

Open ternminal and Run liteserver development server (outside the development console) for front-end hot reloading. Smart contract changes must be manually recompiled and migrated. Open http://localhost:3000 for the web contents.

yarn dev

note: By far, we just finished a simple work to show how NFTC runs. For more details, go to examples.

Summary

Above all, NFTC is an awesome platform for both developers and players. Anyone can depoly their contracts and anyone can have fun with it. For more details, please kindly refer to our slides.
