The Project
An NFT ticketing platform that turns a Stripe payment into an on-chain ERC-1155 ticket, with retry-safe delivery, resale and wallet-signature scanning at the door.
- 10,000+ ticket transactions processed at 98% first-attempt success rate
- Stripe-to-NFT delivery with zero double-mint incidents across all events
- ERC-1155 contract supporting both GA and VIP ticket classes
- Real-time door scanning via wallet signature — no app download required for attendees
- Resale marketplace with configurable royalty splits for event organizers
What We Solved
INSID3RS.IO wanted to replace traditional paper and QR-code event tickets with NFTs — giving attendees verifiable, tradeable digital passes. The core challenge was bridging fiat payment (Stripe) with on-chain NFT delivery reliably: a failed webhook or a slow blockchain confirmation could leave a paying customer without their ticket. The platform also needed to handle ticket resale, transfer restrictions, and real-time door-scanning validation at events.
How We Built It
We engineered a Stripe webhook pipeline with idempotent event processing to prevent double-minting on retries. ERC-1155 smart contracts handle both fungible (general admission) and non-fungible (VIP) ticket types in a single contract. IPFS stores ticket metadata and artwork. Post-payment, NFT delivery is queued and retried with exponential backoff until confirmed on-chain. A separate venue scanning module validates ticket ownership via wallet signature at the door.
