Use-cases

Using the word resource is intentionally abstract because it can represent anything from:

  • Waitlists for events and product launches
  • Event tickets for concert, cinema, online events...
  • Limited Editions
  • Drop-in businesses (Fitness centers, beauty salons, laundry, health clinics, body workers, mind workers, etc.)
  • Reservations for restaurant tables
  • Buzzer system for restaurants and cafés

How does it work?

Service owner creates a queue

  • ERC721 (NFT) smart contract is created with configuration.

Customers enter the queue

  • A unique NFT (ERC721) token is minted that represents the queue ticket.
  • Being an NFT it can be traded on marketplaces.

Queue is pushed forward

  • Owners and conductors can push the queue forward to handle the next ticket in line
  • Ticket owner is notified via the emitted Next event.

Ticket is signed by customer

  • An EAS attestation is created proving the person is in fact holding the ticket

Ticket is verified by owner

  • QR code is scanned and linked to view the EAS attestation
