## Built With
[![React][react.js]][react-url] [![solidity]][solidity-url] [![chainlink]][chainlink-url] [![hardhat]][hardhat-url] [![ethers.js]][ethers-url]
## Getting Started
Make sure you have the following ready:
- [node.js](https://nodejs.org/) installed (developed on LTS v20.12.0)
- [yarn](https://yarnpkg.com/) installed
- [hardhat](https://hardhat.org/) installed
- [MetaMask](https://metamask.io/) installed in your browser
Then create a new repo, open your favorite code editor, and clone the repo with the following cmd:
```bash
git clone https://github.com/Devanshi-Bavaria/CoinFlip.git
```
## Smart-Contracts Deployment
In your terminal, make sure you are in the `CoinFlip` repo, then move to the blockchain folder :
```bash
cd blockchain
```
Then run the following command to install the dependencies:
```bash
yarn install
```
To deploy your smart-contracts:
- To deploy on different chains, you will also have to adjust the `COORDINATOR` and `KEY_HASH` values. You can refer to the [Chainlink docs](https://docs.chain.link/vrf/v2-5/supported-networks#configurations) to get the data for the desired network (if supported).
- Also, make sure that the network is configured in `hardhat.config.js` and that you have defined the required variables in the `.env` file.
- Edit the script in `blockchain/package.json` to deploy the contract on the network of your choice.
- Finally, run the command below to deploy to the network of your choice.
```bash
yarn deploy
```
