Usage

Requires an Etherem based wallet like MetaMask
You'll need some test BNB on the BSC (testnet) network. Visit a faucet to get some free test BNB. Make sure you've set your wallet network to BSC Testnet.
Visit the New York Cat Game website.
Make sure your wallet is on the BSC test network. Press the "Connect" button. This will connect the wallet to the app so it can query the blockchain for your kitties.
Head over to the Marketplace to get some kitties! Once you have 2 kitties you can breed them and have kittens.

Academy Kitties DNA

The DNA structure is a 16 digit number with the following breakdown. The Kitten DNA is a random combination of the parent DNA with a chance for a completely random value.

Running the project locally

Have node 12.x installed
Install the Truffle suite globally via npm install -g truffle
npm install to install the project dependencies
You'll need a local ETH blockchain like Ganache. Can use either the graphical interface or the CLI (npm install -g ganache-cli). If using the graphical app create a new workspace and link the truffle config file /truffle-config.js to the workspace.
Deploy the contracts
1. truffle console
2. migrate
Copy the KittyContract and KittyMarketPlace contract deployed addresses into /src/components/js/service.js into the static chainIdToAddress variable with ID 0x539 (this is the chain ID for Ganache)
Run the app with npm start and open a browser to http://localhost:3000
