Harmony Protocol NFT Store Sample Dapp

This example will help you deploy an HRC-721 (ERC-721 compatible) NFT Store on the Harmony Protocol.

Server

The dashboard, "minter" for setting the inventory and primary issuance of NFTs.

Client

A sample Dapp where users can buy NFTs from the "minter" or "store" through a primary issuance sale.

Users can also sell items on the "market" peer to peer.

Getting Started

1. Install packages npm install
2. (OPTIONAL) Set up your harmony localnet
3. Run npm run deploy <target_network> to deploy the contracts, where <target_network> can be:
   • local: for a local running instance of the Harmony blockchain
   • testnet: for our current long running testnet (current URL: https://api.s0.b.hmny.io/)
   • mainnet0: for our Mainnet (current URL: https://api.s0.t.hmny.io/)
4. In the .env file located in the same directory as this Readme, set ENV=<target_network> where <target_network> is the network you deployed the smart contract to.
5. Use npm start to run the dapp

Note: restarting the dapp IS necessary after re-deploying the contracts

npm start

Making Changes

If you want to point the dapp to a contract that is already deployed on testnet or mainnet, modify the following entries in the .env file:

//HRC721 Contract Addresses
TESTNET_HRC721CROWDSALE='<testnet_HRC721Crowdsale_address>'
TESTNET_HARMONYMINTABLE='<testnet_HRC721_address>'
TESTNET_MIGRATIONS='<testnet_Migrations_address>'

//MAINNET
MAINNET_HRC721CROWDSALE='<mainnet_HRC721Crowdsale_address>'
MAINNET_HARMONYMINTABLE='<mainnet_HRC721_address>'
MAINNET_MIGRATIONS='<mainnet_Migrations_address>'

Replace the address fields with the hexadecimal address pointing to the contract on your network of choice.
