Summary
Paxr is a decentralized event ticketing marketplace on Arbitrum Orbit. The architecture can be optimized for the L2 environment.
Recommended Changes
1. Layer-2 Native Architecture
- Leverage Arbitrum Orbit's native features:
- Low-cost transactions for high-volume ticket minting
- Custom gas token for marketplace fee abstraction
- AnyTrust mode for data availability vs. cost tradeoff
2. State Channels for High-Volume Events
- For events with 1000+ tickets, implement state channels:
- Minting happens off-chain, settled in batches
- Reduces L2 gas costs by 10-100x
- Implement challenge period for dispute resolution
3. Anti-Scalping Mechanisms
- Implement on-chain identity (gitcoin passport or similar) for verified attendees
- Add ticket transfer cooldown periods
- Implement price floors for secondary market resales
- Royalty enforcement via ERC-2981 (already in tech stack pattern)
4. Event Discovery & Indexing
- Add off-chain indexer for event discovery (The Graph or custom)
- Implement full-text search for events (location, date, category)
- Add calendar integration (ICS export, Google Calendar API)
5. Analytics Dashboard
- Event organizers dashboard with:
- Ticket sales velocity, attendance rate, revenue charts
- Demographic breakdown of attendees
- Secondary market activity monitoring
6. Testing & Quality
- Foundry fuzz testing for smart contracts
- E2E tests for: create event → mint ticket → transfer → resell → check-in
- Load testing for high-volume ticket drops
