NFTickets

Please note - NFTickets is currently in early development - some features are not yet included in this release.

NFTickets allows users to authenticate with their blockchain wallets and generate ERC1155 tokens for their events, allowing them to create tickets that can be sold on the NFTickets Marketplace to other users. Event organisers are charged a 20% deposit fee (This is used as a stake to discouracge bad behaviour = good actors will be reimbursed 19% depostit, resulting in a final 1% fee). Buyers are able to purchase one or multiple tickets on the marketplace.

All purchases are tied to USD and utilise Chainlink pricefeed to charge realtime dolar equivalents in the chain's native asset.

Ticket buyers can then use the all to generate a privately signed message that generates a QR code on their phone.

Event organisers are able to scan QR codes for their events to ensure that attendees own tickets to their event, and are in possession of the wallet that owns the ticket, and are not impoersonating a public address that has purchased a ticket.

Staking, complaints, refunds, and slashing mechanics are not included in this release.

This project is using:

• ethereum-react-native-boilerplate for most of the core functions.
• WalletConnect v1 react-native integration for authenthication (we use a slightly modiefied version, located in ./src/WalletConnect to allow to modify the enable function of Moralis).
• react-moralis for react hooks
• react-native-qrcode-generator for QR code generation
• react-native-image-picker for content upload
• react-native-qrcode-scanner for QR code scanning and verification of ticket ownership
• Formik and yup for form iupload and validation

Smart contract

The solidity contract is located in artifacts > contracts

Chainlink Pricefeed is integrated into the marketplace contract (lines 90-193 for relevant sections), and calls the AVAX/USD pricefeed on the Avalanche testnet.

IPFS is accessed via a Moralis gateway.
