This backend has been built with the game Planet-Giant for the Cronos & Moralis Hackathon - August-September 2022.

The entire project is divided in 3 parts. Here are the links to all the different github repos:

• Unity Game: https://github.com/shamrockstudios/Planet-Giant_Game
• React Webapp: https://github.com/shamrockstudios/Planet-Giant_Webapp
• Backend contracts: https://github.com/shamrockstudios/Planet-Giant_Contracts

Description

This backend cover 2 parts:

• Batch mint: node.js code to allow the NFT's images and attributes to be generated and stored on IPFS.
• Smart-contracts: NFTs and Marketplace smart-contract to mint NFTs and sell/buy them on the dedicated marketplace.

Installation

Make sure you have the following ready:

• node.js installed (developped on LTS v16.16.0)
• typescript installed (developped on v4.7.4)
• yarn installed
• MetaMask (or any web3 compatible wallet) installed in your browser

Once your config is ready, create a new repo, open your favorite code editor, and clone the repo with the following cmd:

git clone https://github.com/shamrockstudios/Planet-Giant_Contracts.git .

Install all package dependancies by running:

yarn install

Generate the NFT attributes & save them on IPFS:

1. Navigate in:

cd src

2. Then edit the file image.js to match your content, then run:

node image.js

3. Finally edit the file metadata.js (don't forget to edit the IPFS image path with the newly generated one), and run:

node matadata.js

Deploy your smart-contract

Go back to the root folder by typing:

cd ..

Now you'll have to edit a few file:

• The deployment script in scripts\deploy.ts with your data (or even better create a .env file);
• The NFT_minter contract in contract\NFT_minter.sol with your own IPFS path;
• The hardhat.config.ts file depending on which network you want to deploy your NFT collection. Once you're ready, simply run:

yarn deploy

And let the magic do its thing!

A BIG THANKS TO MORALIS, CRONOS AND THEIR RESPECTIVE TEAMS !!!
