• pnpm (recommended) or npm
• A .env file in the smart-contracts directory with:

  PRIVATE_KEY=your_private_key
  POLYGON_AMOY_RPC_URL=your_polygon_amoy_rpc_url

1. Install dependencies:

   cd smart-contracts
   pnpm install

2. Compile contracts:

   npx hardhat compile

3. Deploy to Polygon Amoy testnet:

   # Deploy NECTR Token
   npx hardhat ignition deploy NectrModule --network polygonAmoy
   
   # After token deployment, update .env with the token address:
   # NECTR_TOKEN_ADDRESS=deployed_token_address
   
   # Deploy Staking contract
   npx hardhat ignition deploy NectrStakingModule --network polygonAmoy

4. After deployment, copy the contract addresses and update the frontend .env file.

Copy these addresses to your frontend .env file:

# Frontend .env
