  In order to deploy contract you will need:

1. Ensure you have the following prerequisites:

   • $ETH on ETH Sepolia Testnet.
   • ETH Sepolia Testnet RPC endpoint.

2. Create a .env file with the following content in smartContract:

   ALCHEMY_RPC_KEY="Alchemy RPC"
   PK="Deployer private key"

3. Create a .env file with the following content in frontend:

   NEXT_PUBLIC_CHAIN_ID = "11155111"
   NEXT_PUBLIC_PROJECT_ID = ""
   NEXT_PUBLIC_RPC = "https://ethereum-sepolia-rpc.publicnode.com"
   NEXT_PUBLIC_SIGNATURE_WEBHOOK = ""
   DATABASE_URL=""
   UPLOADTHING_TOKEN=""

Set-up

1. Deploy all contracts to Sepolia

   Run the Hardhat deployment script:

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

2. Move ABI files to the frontend After deployment, ABI files will be generated in the deployments folder. Copy them to your frontend project:

   frontend/ticket-app/smartContracts/abis

3. Generate Prisma Client

   npx prisma generate

4. Run the website From the frontend directory, start the Next.js app:

   npm run dev

Chainlink Integration Files

1. Data feed

• contracts/market/TicketLaunchpad.sol - Fetch the price from a data feed and ensure the received amount corresponds to the fetched price.

2. Chainlink Function contracts/secondaryMarket/SecondaryMarketCore.sol - Retrieve ticket usage data via a Chainlink Function and, upon listing, check whether the ticket has been used to prevent fraudulent listings.
