-
Requires an Etherem wallet like MetaMask
-
You'll need some test ETH on the Ropsten network. Visit a faucet to get some free test ETH. Make sure you've set your wallet network to
Ropsten. -
Visit the Academy Kitties website.
-
Make sure your wallet is on the
Ropstentest 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.
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.
| DNA Digits | Cattribute | Values |
|---|---|---|
| 00-01 | Body Color | 10-99 |
| 02-03 | Accent Color | 10-99 |
| 04-05 | Eye Color | 10-99 |
| 06-07 | Ear Color | 10-99 |
| 08 | Eye Shape | 0-7 |
| 09 | Pattern | 0-3 |
| 10-11 | Pattern Color | 10-99 |
| 12-13 | Pattern Accent Color | 10-99 |
| 14 | Animation | 0-4 |
| 15 | Mysterious | 0-7 |
When parent kitties breed they need time to rest before breeding again. Breed cooldowns are defined below.

- Have node
12.xinstalled - Install the Truffle suite globally via
npm install -g truffle npm installto 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.jsto the workspace. - Deploy the contracts
truffle consolemigrate
- Copy the
KittyContractandKittyMarketPlacecontract deployed addresses into/src/components/js/service.jsinto thestatic chainIdToAddressvariable with ID0x539(this is the chain ID for Ganache) - Run the app with
npm startand open a browser tohttp://localhost:3000
Deploying the project contracts to a test net requires a .env config file which expects the following entries. You can get a free Infura API key by creating an account at their website here.
# 12 word seed phrase for the test net HD wallet provider
MNEMONIC=
# Infura project ID for the hosted ETH node
INFURA_PROJECT_ID=
Follow the local deployment instructions above except use truffle console --network ropsten (or your test network of choice).
