A decentralized event ticketing platform that leverages blockchain technology to issue NFT-based tickets, ensuring transparency, security, and ownership.

This project is currently a work in progress. Features and functionality may change as development continues.

• Next.js – For building the UI and handling server-side rendering.
• Tailwind CSS – For styling the application.
• Ethers.js – For interacting with the Ethereum blockchain.
• Wagmi – Simplifies Ethereum wallet integration.

• Smart Contracts – Written in Solidity for ticket issuance and transactions.
• Hardhat – For smart contract development, deployment, and testing.
• OpenZeppelin – Secure contract development library.
• Pinata IPFS – For storing event metadata (name, description, image, etc.).
• The Graph – For querying blockchain data efficiently.

• Ethereum / Sepolia Testnet – Smart contracts deployed on Ethereum for scalability and security.

• MetaMask – For users to connect their wallets and manage NFT tickets.

1. NFT-Based Tickets – Each ticket is minted as an NFT, ensuring ownership and uniqueness.
2. Event Creation – Organizers can create events, set ticket prices, and ticket supply.
3. Ticket Purchase – Users can buy tickets using ETH, and NFTs are transferred to their wallets.
4. Resale Marketplace – Users can resell tickets in a decentralized manner.
5. Ticket Verification – Organizers can verify ticket ownership at event entry.

• EventFactory: Manages event creation, cancellation, and tracking.
• TicketNFT: Mints and manages NFT tickets tied to events.
• TicketSale: Handles ticket purchases and refunds, integrating with EventFactory and TicketNFT.
• TicketVerification: Verifies ownership of NFT tickets.
• TicketMarketplace: Allows secondary market trading of NFT tickets.

git clone https://github.com/gazamba/nft-ticketing-dapp.git
cd nft-ticketing-dapp

cd frontend
npm install  # or yarn install

cd backend
npm install  # or yarn install

Create a .env file inside backend/ and frontend/ with the following variables:

INFURA_RPC_URL=https://sepolia.infura.io/v3/YOUR_INFURA_API_KEY
INFURA_PRIVATE_KEY=YOUR_WALLET_PRIVATE_KEY
ETHERSCAN_API_KEY=YOUR_ETHERSCAN_API_KEY

PINATA_PUBLIC_GATEWAY_URL=<Pinata-gateway>
PINATA_JWT_TOKEN=<JWT-FROM-Pinata>
INFURA_RPC_URL=https://sepolia.infura.io/v3/YOUR_INFURA_API_KEY

cd backend
npx hardhat compile

Local blockchain with hardhat node
npx hardhat ignition deploy ignition/modules/<contract-module>.ts --network localhost

cd frontend
npm run dev  # or yarn dev

The application will be available at: http://localhost:3000

To run unit tests for your smart contracts:

cd backend
npx hardhat test

Once tested, deploy the smart contracts on Ethereum Sepolia:

npx hardhat ignition deploy ./ignition/modules/FullDeployment.ts --network sepolia

• Use OpenZeppelin libraries to prevent vulnerabilities.
• Audit contracts before deploying
• Keep private keys secure and never expose them in code.
