Tizzle is a refundable staking-based event ticketing protocol built on Solana. Instead of purchasing tickets traditionally, users stake tokens to reserve attendance. If they attend the event, their stake is refunded, reducing no-shows while removing payment friction.
Tizzle is a Solana-based event ticketing protocol that replaces traditional ticket purchases with a refundable staking mechanism. Users lock tokens when registering for events and receive refunds after verified attendance, creating a commitment-based system that dramatically reduces no-show rates while eliminating payment friction.
The protocol introduces a Pay-per-Slot business model where organizers pay a flat platform fee for every attendee slot created, while attendees stake tokens that are held in escrow and returned after attendance verification. This creates aligned incentives for both organizers and attendees without charging attendees directly.
To become the standard infrastructure for on-chain event management, enabling a future where attendance verification, reputation systems, and token utility are seamlessly integrated into everyday event experiences.
Traditional event ticketing systems face several critical challenges:
Free events often experience 30–50% no-show rates, wasting organizer resources.
Traditional payment methods create barriers, especially for international attendees.
Most crypto tokens lack real-world use cases beyond speculation.
Lack of transparent, on-chain attendance verification.
Tizzle addresses these issues by building entirely on Solana, using stake-based commitment mechanics, deterministic smart contracts, and a fee-backed sustainable model.
Tizzle introduces a five-step process that ensures commitment without upfront payment:
Tizzle never charges attendees directly. Platform revenue comes exclusively from organizer fees, while attendee stakes are held in escrow and returned after attendance verification.
Tizzle implements a Pay-per-Slot model that charges event organizers a flat fee for every attendee slot created, regardless of whether the slot is filled.
Total Platform Fee = Event Capacity × Fee Per Slot Example: capacity = 100 attendees fee_per_slot = 0.0005 SOL Total Fee = 100 × 0.0005 SOL = 0.05 SOL
| Property | Description |
|---|---|
| Fee Model | Linear Pay-per-Slot |
| Charged To | Event Organizer |
| Payment Time | During event creation |
| Destination | Platform Treasury PDA |
| Attendee Cost | Zero platform fee |
Platform Revenue (Protocol)
Source: Organizer platform fees (paid in SOL) Formula: platform_fee = capacity × fee_per_slot Destination: Platform Treasury PDA Use: Protocol development and maintenance
Organizer Revenue
Sources: 1. Host Fee (optional) - Percentage deducted from attendee refunds - In same token as stake - Example: 5% of 10 SOL = 0.5 SOL 2. No-Show Penalty - Full stake from non-attending users - In same token as stake - Compensates for lost event capacity
| Flow Type | From | To | Token |
|---|---|---|---|
| Platform Fee | Organizer Wallet | Platform Treasury | SOL (always) |
| Stake Deposit | Attendee Wallet | Escrow Vault | Any supported token |
| Refund (Attended) | Escrow Vault | Attendee Wallet | Same as stake |
| Host Fee | Escrow Vault | Org Treasury | Same as stake |
| No-Show Penalty | Escrow Vault | Org Treasury | Same as stake |
Tizzle consists of three integrated layers:
The protocol uses Program Derived Addresses (PDAs) for deterministic account management:
| Account | Purpose | Seeds |
|---|---|---|
| Protocol Config | Global protocol settings | ["config"] |
| Organization | Organizer profile and treasury | ["organization", organizer] |
| Event | Event configuration and metrics | ["event", org, event_id] |
| Registration | Attendee ticket record | ["registration", event, user] |
| Escrow Vault | Holds staked tokens | ["escrow", event] |
| Platform Treasury | Collects platform fees | ["treasury"] |
Direct lamport transfers via System Program. Most gas-efficient option.
Standard fungible tokens using Token Program. Backward compatible.
Next-gen tokens with transfer fees, hooks, and metadata support.
Platform fees are always paid in native SOL, regardless of the stake token type. This ensures consistent protocol revenue while allowing flexibility in stake token selection.
Events progress through deterministic states based on timestamps, ensuring predictable behavior without requiring manual updates.
| Status | Condition | Actions Allowed |
|---|---|---|
| Available | now < start_time | Registration open |
| Ongoing | start_time ≤ now < end_time | Check-in active |
| Ended | end_time ≤ now < unlock_time | No actions |
| Settlement | now ≥ unlock_time | Refunds claimable |
| Closed | All refunds processed | Event finalized |
Once created, events cannot be deleted. This ensures historical transparency, prevents organizer manipulation, and maintains reliable on-chain attendance records. Critical fields like stake_amount, capacity, and organizer cannot be modified after creation.
All accounts use Program Derived Addresses, ensuring only the program can authorize critical operations.
Registration accounts track refund status, preventing users from claiming refunds multiple times.
All token transfers use transfer_checked with mint and decimal validation.
Strict time-based checks prevent premature refunds and ensure proper event progression.
Wallet-Based Authentication
1. Client requests nonce from server 2. Client signs message with wallet private key 3. Server verifies signature using Ed25519 4. JWT token issued for authenticated sessions 5. All protected endpoints require valid JWT
On-Chain Verification
All POST and PUT operations verify on-chain state before database updates. The blockchain is the source of truth. The backend database serves as a cache and metadata store, but all critical operations are verified against on-chain state.
Transaction costs average $0.00025, making micro-transactions economically viable for event ticketing.
65,000 TPS capacity enables simultaneous registrations during high-demand events without congestion.
Native mobile wallet adapters provide seamless on-site check-in experiences via QR codes.
400ms block times enable real-time attendance verification and instant refund processing.
Risk: Bugs or vulnerabilities in smart contract code could lead to loss of funds.
Mitigation:
Risk: Users may be unfamiliar with crypto wallets and staking mechanisms.
Mitigation:
Risk: Solana network congestion or downtime could affect event operations.
Mitigation:
Tizzle represents a paradigm shift in event ticketing, replacing traditional payment models with a commitment-based staking mechanism that aligns incentives for all participants. By leveraging Solana's high-performance blockchain, Tizzle delivers zero platform fees for attendees, instant refunds, and transparent on-chain attendance records.
The protocol's design prioritizes security, transparency, and user experience while maintaining the flexibility to evolve through community governance. As blockchain technology continues to mature, Tizzle demonstrates how decentralized systems can solve real-world problems more effectively than traditional alternatives.
Tizzle aims to become the standard infrastructure for on-chain event management, enabling a future where attendance verification, reputation systems, and token utility are seamlessly integrated into everyday event experiences.
