StarChain DAPP

In this project I deployed a unfungible token contract (ERC721) on the Ethereum Rinkeby network.
I also develop a minimalist Front End to interact with the main functions of the contract:
The user can then register a new stars that will be stored as an ERC721 token on the blockchain, or look up for existing ones..

Getting started

Prerequesites: You will need Metamask and an Infura account.

1. Clone or download this repository
2. Install dependencies

cd starChainV2
npm install # will install truffle-hdwallet-provider
cd app
npm install # will install all other dependencies (web3, openzeppelin...)
cd ..

3. Run tests:

truffle develop
truffle(develop)> test

1. Metamask:

• Connect to the Rinkeby network.
• Look for your mnemonic passphrase in "settings"

1. Write your Metamask mnemonic in a .secret file and save it in starChainV2/
2. Infura: write your Infura Project ID key in a .infuraKey file and save it in starChainV2/
3. Serve Front End:

cd app
npm run dev

5. Access Front End at http://localhost:8080
