*Notes: The project running on Kovan testnet.

The first things you need to do are cloning this repository and installing its dependencies:

git clone https://github.com/anhnt4288/pokeNFT.git
cd pokeNFT
npm install

Before deploying your contract you have to copy the .env_example to .env and set the credentials in your .env file

Then, on a new terminal, go to the repository's root folder and run this to deploy PokeToken contract:

npx buidler run scripts/deploy_PokeToken.js --network kovan

Finally, we can run the frontend with:

cd frontend
npm install
npm start

Open http://localhost:3000/ to see your Dapp. You will need to have Metamask installed and listening to the Kovan network.

Your environment will have everything you need to build a Dapp powered by Buidler and React.

• Buidler: An Ethereum development task runner and testing network.
• Chainlink: A library to interact with a descentralized oracle network.
• OpenZeppelin: A library of secure smart contracts.
• Mocha: A JavaScript test runner.
• Chai: A JavaScript assertion library.
• ethers.js: A JavaScript library for interacting with Ethereum.
• Waffle: To have Ethereum-specific Chai assertions/mathers.
• A sample frontend/Dapp: A Dapp which uses Create React App.

Additional information about Chainlink and the database for the metadata API is available in the docs section. There is also an article on Medium.

• Invalid nonce errors: if you are seeing this error on the buidler node console, try resetting your Metamask account. This will reset the account's transaction history and also the nonce. Open Metamask, click on your account followed by Settings > Advanced > Reset Account.
