Local Setup

To set up the project locally, follow these steps:

1. Clone the repository:

   git clone https://github.com/4rjunc/carbon.git
   cd carbon
   

2. Install dependencies:

   npm install
   

3. Create a .env.local file in the root directory and add necessary environment variables:

   NEXT_PUBLIC_POLYGON_RPC_URL=your_polygon_rpc_url
   NEXT_PUBLIC_FILECOIN_API_KEY=your_filecoin_api_key
   

4. Run the development server:

   npm run dev
   

5. Open http://localhost:3000 in your browser to see the application.

Smart Contract Deployment

1. Install Hardhat (if not already included in project dependencies):

   npm install --save-dev hardhat
   

2. Compile contracts:

   npx hardhat compile
   

3. Deploy to Polygon testnet (Mumbai):

   npx hardhat run scripts/deploy.js --network mumbai
   

Remember to update the deployed contract address in your .env.local file.
