A real ticketing business.
Fully on Cardano.
Two phases. One production system. Phase 1 built the foundation — on-chain event creation, ticket minting, transfers, and attendance. Phase 2 brings the marketplace, royalties, anti-scalping, and wallet onboarding for 200,000+ users. Already building. Already live.
What’s built. What this funds.
Foundation (Already Built)
- On-chain event creation with master manifest NFTs
- CIP-68 ticket NFTs minted for each sale
- Custodial wallet flows — users get wallets without crypto UX
- Ticket transfer flows with CIP-68 metadata updates
- Attendance verification with batched updates and closing manifests
Marketplace (What This Funds)
- Cardano-native secondary marketplace for ticket resale
- Royalty enforcement — artists get paid on every resale automatically
- Anti-scalping controls with price ceilings and fair resale rules
- Wallet creation for 200,000+ existing Sellout users
- Organizer tools for resale configuration and data visualization
Every step on-chain.
From event creation to check-in, every interaction becomes a Cardano transaction.
Event created with on-chain manifest and policy
CIP-68 NFT ticket issued for each sale
Primary sale through Sellout’s existing platform
Peer-to-peer with on-chain metadata update
Marketplace listing with royalty and price rules enforced
Check-in recorded as CIP-68 metadata write
The only chain that can do this at scale.
Cardano’s eUTxO model gives every ticket deterministic ownership — you know exactly what you hold and what it can do. Native multi-asset support means tickets exist as first-class assets without a smart contract just to hold them. CIP-68 updatable metadata means a ticket’s state can change — from valid to transferred to attended — while the asset stays with the owner.
Low, predictable fees are critical when you’re minting thousands of tickets per event. Security and decentralization matter when enterprise clients need to trust the chain. And the UX can feel like Web2 while being truly Web3 — which is exactly what Sellout’s 200,000 users need.
Every ticket a real asset. Every resale fair. Every check-in on-chain. Cardano is the only chain that can deliver Web2-grade reliability with Web3-grade guarantees.
