We built SuiTix because the status quo leaves too many real fans outside the venue and too much value off the stage. Scalping, opaque fees, QR screenshots that get reused, and resale experiences that reward bots over communities—none of that felt inevitable. Sui’s object-centric design, dynamic NFTs, and the Kiosk + Transfer Policy combo let us design a system where rules are enforced by code, ownership is crystal clear, and loyalty actually compounds over time. What SuiTix delivers Authentic tickets as first-class Sui objects with rich Display metadata and a clean lifecycle (mint → own → list/resell → check-in). Secure secondary market via Kiosk, where every sale is mediated by a Transfer Policy that enforces fair-price ranges, time windows, and “not checked-in” requirements before a trade can finalize. Dynamic primary pricing that reacts to real demand (with guardrails so it’s responsive, not volatile). Loyalty that matters: Bronze/Silver/Gold/Platinum tiers, points for purchases and attendance, milestone badges, and a claim-based referral system that fits Sui’s ownership rules. Anti-scalping controls: per-wallet purchase caps, cool-downs, and resale restrictions that make drops calmer and markets fairer. How we put it together (textual tour of the smart contracts) Ticketing layer (the ticket as a living object) A Ticket is an owned Sui object that carries its class reference, seat info (or “general admission”), and a simple “consumed” flag for check-in. Display templates make it render like an NFT card everywhere (wallets, marketplace, our UI). Check-in is just a state transition: once marked, it’s visibly “used” and can’t be resold. Tickets are minted against a Ticket Class that defines supply, base price, metadata, and organizer economics. Marketplace layer (Kiosk integration without surprises) We don’t reinvent a marketplace. Sellers keep a personal, on-chain Kiosk that can hold items, list them at a fixed price, and accrue their sale proceeds. While listed, a ticket is immutable and not withdrawable—no tampering. We support two custody modes: Soft: owners hold tickets in their wallet and only place them in a Kiosk when they choose to sell. Strong: after primary purchase, the ticket is automatically placed (and locked) in the buyer’s Kiosk so every future transfer is a Kiosk trade—no off-market side doors. Transfer Policy (the rules engine for resale) There’s a single policy dedicated to the Ticket type. Every Kiosk purchase produces a transfer request that the policy must confirm. Confirmation verifies that the price is within the allowed band for the class, the event hasn’t started (or resale hasn’t been explicitly paused), and the ticket isn’t checked-in. It also captures creator royalties into an on-chain balance organizers can withdraw. If any rule fails, the whole trade cleanly aborts. Loyalty (points, badges, and referrals designed for Sui) Fans have a personal Loyalty Card object that tracks balances and tier. Badges are non-transferable collectibles for milestones. Referrals use a shared “pending claims” registry: the new user proves the invite, the registry validates, and both parties get credited—no cross-owner mutations needed. We hook loyalty updates into primary buys, successful resales, and check-ins. Dynamic pricing (responsive, not noisy) Ticket Classes can opt into demand-aware pricing. The system looks at recent sales velocity and nudges price up/down within safe bounds set by the organizer. Guardrails prevent extreme swings, and toggles let organizers opt out for fixed-price shows. Anti-scalping (friction where it counts) We track per-wallet counters at the event level, apply cool-downs during hot drops, and disallow post-check-in resales. Optional “presale lists” and purchase windows make access fair for communities. State design (shared vs. owned) Global catalogs (events, classes, referral registry) live as shared objects; tickets, badges, and loyalty cards stay owned by users. This separation keeps hot paths fast and permissions crystal clear. Frontend & UX (how it feels to use) Next.js + TypeScript with Sui dApp Kit for wallet and signing. One-click flows using Programmable Transaction Blocks: Primary buy: pay once, receive the ticket, and—if strong custody is on—have it placed and locked in your Kiosk automatically. Resale: press Buy on a listing; the marketplace executes a Kiosk purchase, the policy confirms the rules, and ownership flips atomically. Attendee check-in: scan once; the ticket flips to “used” and can’t re-enter the resale pool. Primary buy: pay once, receive the ticket, and—if strong custody is on—have it placed and locked in your Kiosk automatically. Resale: press Buy on a listing; the marketplace executes a Kiosk purchase, the policy confirms the rules, and ownership flips atomically. Attendee check-in: scan once; the ticket flips to “used” and can’t re-enter the resale pool. Marketplace grid merges Kiosk listing events with Ticket Display metadata for crisp cards. Organizer controls for pausing resale, withdrawing royalties, and tuning price bounds—no redeploy required.
Challenges we ran into
(and how we solved them) Sui’s ownership boundaries meant our first referral design couldn’t modify a referrer’s object during a newcomer’s transaction. The claim-based registry pattern fixed that cleanly. Entry-point ergonomics forced us to split certain combined flows and pass addresses instead of trying to smuggle optional mutable references. Cleaner in the end. Learning Kiosk + policy interplay took iteration: listing states, lock semantics, and when the transfer request is produced. Once we aligned on strong custody, everything snapped into place. Demand-based pricing without exploits required guardrails, sanity caps, and smoothing—users see “responsive,” not “random.” PTB complexity: bundling ticketing, loyalty, and marketplace actions in the right order with the right coin handling was a puzzle we’re glad we solved. Accomplishments we’re proud of A complete loop—primary sale, policy-enforced resale, check-in, royalties, and loyalty—that’s atomic and auditable end-to-end. Real anti-scalping and fair-pricing mechanics, not just rhetoric. A badge-driven loyalty system that actually feels fun. A modular contract suite that teams can extend without touching core logic.
What we learned
along the way Sui’s object model makes stateful tickets first-class citizens instead of workarounds. Programmable Transaction Blocks unlock surprisingly elegant UX when you think in “atomic steps.” Kiosk + Transfer Policy is a safer, simpler foundation than bespoke marketplaces with scattered rules. When ownership rules push back, separate concerns across transactions or pivot to shared registries—don’t fight the model.
What's next
Social groups, ticket splitting, and shared itineraries. Cross-event perks and partner redemptions. Smarter pricing (better signals now; ML when data warrants). Native apps and a measured mainnet rollout with real venues. Bridges to incumbents to onboard the mainstream, and multi-chain reads with Sui as source of truth.

🎫 SuiTix - Next-Generation Blockchain Ticketing Platform
Production-ready ticketing ecosystem leveraging advanced Sui blockchain primitives including Kiosk standard, TransferPolicy, dynamic fields, and programmable transaction blocks
🌟 Overview
SuiTix is an enterprise-grade event ticketing platform that showcases the full power of the Sui blockchain. Built with production-ready Move smart contracts and a sophisticated Next.js frontend, it demonstrates advanced blockchain patterns including the Sui Kiosk standard, custom TransferPolicy rules, dynamic NFT fields, and complex royalty distribution.
Live Demo: Coming Soon | Transaction Explorer: View on Sui Testnet
🏆 Advanced Sui Features Implemented
🎯 Sui Kiosk Standard Integration
We've implemented the full Sui Kiosk specification for a decentralized NFT marketplace:
// Kiosk adapter for ticket NFTs with enforce/soft modes
module suitix::kiosk_adapter {
public fun place_ticket(ticket: Ticket, kiosk: &mut Kiosk, cap: &KioskOwnerCap)
public fun lock_ticket(kiosk: &mut Kiosk, cap: &KioskOwnerCap, policy: &TransferPolicy<Ticket>, ticket: &Ticket)
public fun list_ticket(kiosk: &mut Kiosk, cap: &KioskOwnerCap, ticket_id: ID, price: u64)
}
Why This Matters:
- ✅ Native compatibility with Sui ecosystem marketplaces
- ✅ Standard purchase/transfer flows without custom escrow
- ✅ Built-in royalty enforcement via TransferPolicy
- ✅ Each seller maintains their own kiosk (decentralized architecture)
🔐 TransferPolicy with Custom Rules
Advanced royalty enforcement that validates transfers with multi-party fee distribution:
module suitix::policy {
// Validates ticket transfers with comprehensive rule checking
public fun confirm_with_rules(
policy: &mut TransferPolicy<Ticket>,
request: TransferRequest<Ticket>,
event: &mut Event,
config: &ResaleConfig,
ticket: &Ticket,
clock: &Clock,
marketplace_treasury: &mut MarketplaceTreasury,
platform_fee_payment: Coin<SUI>,
organizer_royalty_payment: Coin<SUI>,
) {
// 1. Floor/ceiling price validation
// 2. Event timing checks
// 3. Ticket status verification
// 4. Three-way royalty split: Platform (2%) | Organizer (remaining) | Seller (price)
}
}
Rule Enforcement:
- ✅ Price floor/ceiling validation
- ✅ Event timing restrictions (no resale after event starts)
- ✅ Ticket status checks (used tickets can't be transferred)
- ✅ Automated royalty distribution to multiple parties
🧩 Dynamic Fields for Validation
Innovative non-destructive ticket validation using Sui's dynamic fields:
// Validation is stored as a dynamic field on Event object
// Ticket NFT remains unmodified in user's wallet!
public fun validate_ticket(
ticket_id: ID, // Just the ID, not the object itself
event: &mut Event,
cap: &OrganizerCap,
clock: &Clock,
) {
// Add validation record as dynamic field
dynamic_field::add(&mut event.id, ticket_id, ValidationRecord {
validated_at: clock::timestamp_ms(clock),
validator: tx_context::sender(ctx),
});
}
Why This Is Revolutionary:
- ✅ Organizer can validate tickets they don't own
- ✅ Ticket NFT stays in user's wallet (no transfer needed)
- ✅ On-chain proof of attendance without modifying the NFT
- ✅ Enables future airdrops to validated attendees
💰 Treasury Architecture & Fee Distribution
Sophisticated three-way payment split with platform fee treasury:
module suitix::marketplace {
public struct MarketplaceTreasury has key {
id: UID,
balance: Balance<SUI>, // Accumulated platform fees
admin: address,
}
// Platform collects 2% of royalties, organizer gets the rest
public fun deposit_platform_fee(treasury: &mut MarketplaceTreasury, fee: Coin<SUI>)
public entry fun withdraw_fees(treasury: &mut MarketplaceTreasury, cap: &MarketplaceCap, amount: u64)
}
Payment Flow on Secondary Sales:
Sale Price: 10 SUI
├─ Seller receives: 10 SUI (full price)
├─ Organizer royalty (5% = 0.5 SUI)
│ ├─ Platform fee (2% of price = 0.2 SUI) → MarketplaceTreasury
│ └─ Organizer share (0.3 SUI) → Event Treasury
└─ Buyer pays: 10.5 SUI total
🎭 Capability-Based Access Control
Zero-trust security using Move's capability pattern:
// OrganizerCap: Manage events, validate tickets, withdraw revenue
public struct OrganizerCap has key, store {
id: UID,
event_id: ID,
organizer: address,
}
// MarketplaceCap: Withdraw platform fees, manage marketplace
public struct MarketplaceCap has key, store {
id: UID,
admin: address,
}
// PlatformCap: Award loyalty points, manage rewards catalog
public struct PlatformCap has key, store {
id: UID,
admin: address,
}
// TransferPolicyCap: Manage transfer rules, withdraw royalties from policy
public struct TransferPolicyCap<phantom T> has key, store {
id: UID,
policy_id: ID,
}
Security Benefits:
- ✅ Only capability holder can perform privileged operations
- ✅ Capabilities are transferable (can sell event to new organizer)
- ✅ No address-based access control (compromised key = no access)
- ✅ Type-safe: Can't use wrong cap for wrong operation

🔧 PTB (Programmable Transaction Block) Builders
Located in frontend/src/lib/ptb/:
Purchase from Kiosk (purchaseFromKiosk.ts):
export function buildPurchaseFromKioskTx(params: PurchaseFromKioskParams): Transaction {
const tx = new Transaction();
// 1. Split coins for payment, platform fee, and organizer royalty
const [paymentCoin, platformFeeCoin, organizerRoyaltyCoin] = tx.splitCoins(tx.gas, [
tx.pure.u64(priceMist),
tx.pure.u64(platformFee.toString()),
tx.pure.u64(organizerRoyalty.toString()),
]);
// 2. Purchase from seller's kiosk
const [ticket, transferRequest] = tx.moveCall({
target: '0x2::kiosk::purchase',
typeArguments: [TICKET_TYPE],
arguments: [sellerKiosk, ticketId, paymentCoin],
});
// 3. Confirm with policy (validates rules + distributes royalties)
tx.moveCall({
target: `${POLICY_MODULE}::confirm_with_rules`,
arguments: [
policy, transferRequest, event, resaleConfig, ticket, clock,
marketplaceTreasury, platformFeeCoin, organizerRoyaltyCoin
],
});
// 4. Transfer ticket to buyer (or lock in buyer's kiosk for enforce mode)
tx.transferObjects([ticket], buyerAddress);
return tx;
}
🗺️ Interactive Seat Selection
SeatMap Component (components/tickets/SeatMap.tsx):
- ✅ Stadium-style circular layout with stage
- ✅ Real-time availability via blockchain event queries
- ✅ Visual feedback (available/selected/taken)
- ✅ Dynamic scaling for 100-10,000+ seat venues
- ✅ Row/seat labeling (A1, B5, etc.)
How It Works:
// 1. Query blockchain for TicketMinted events
const mintedEvents = await suiClient.queryEvents({
query: { MoveEventType: `${PACKAGE_ID}::ticket_nft::TicketMinted` },
filter: { Sender: eventId },
});
// 2. Extract taken seats
const takenSeats = mintedEvents.map(e => e.parsedJson.seat_number);
// 3. Generate seat layout
const seats = generateStadiumLayout(totalSeats, takenSeats);
// 4. Handle selection
<Seat
number={seat.number}
status={seat.status} // 'available' | 'selected' | 'taken'
onClick={() => onSelect(seat.number)}
/>
🔐 zkLogin Integration (Enoki)
Gasless Onboarding:
// OAuth via Google with zkLogin
import { EnokiFlowProvider } from '@mysten/enoki';
<EnokiFlowProvider apiKey={ENOKI_API_KEY}>
<GoogleSignIn
onSuccess={(zkProof) => {
// User authenticated with Google
// Zero-knowledge proof generated
// Sui address derived from OAuth token
}}
/>
</EnokiFlowProvider>
Benefits:
- ✅ No wallet installation required
- ✅ Familiar OAuth flow (Google, Facebook, Twitch)
- ✅ Sponsored transactions for first-time users
- ✅ Progressive decentralization (can export private key later)
📊 Real-Time Dashboard
Platform Admin View (organizer/dashboard/page.tsx):
- 📈 Lifetime revenue (primary sales + royalties)
- 🎟️ Total tickets sold across all events
- 🏆 Top performing events by sell-through rate
- 💰 Platform fee balance from MarketplaceTreasury
- 🔓 One-click withdrawal (only visible to MarketplaceCap holder)
Technical Implementation:
// Detect if user is platform admin
const marketplaceCap = await fetchMarketplaceCap(userAddress);
if (marketplaceCap) {
// Fetch accumulated platform fees
const balance = await fetchMarketplaceTreasuryBalance(MARKETPLACE_TREASURY);
// Show admin panel
<PlatformAdminPanel
balance={balance}
onWithdraw={() => {
const tx = createWithdrawPlatformFeesTx(
MARKETPLACE_TREASURY,
marketplaceCapId,
balance
);
signAndExecute({ transaction: tx });
}}

💡 Advanced Technical Details
🔄 Object Ownership Architecture
Shared Objects (Multiple users can interact):
Event // Multiple buyers purchase tickets simultaneously
EventRegistry // Global event discovery
RewardsCatalog // Everyone can view available rewards
TransferPolicy // Used by all kiosk transactions
MarketplaceTreasury // Platform collects fees from all sales
Owned Objects (Single owner):
Ticket // Buyer owns their ticket
LoyaltyCard // User owns their loyalty card
OrganizerCap // Event creator owns capability
MarketplaceCap // Platform admin owns capability
Kiosk // Each seller owns their kiosk
Why This Matters:
- ✅ Shared objects enable parallel execution (high throughput)
- ✅ Owned objects provide strict ownership guarantees
- ✅ Sui's consensus-less fast path for owned-object transactions
- ✅ No global locks = no bottlenecks
🎨 Ticket NFT Display Metadata
On-Chain Display (visible in wallets):
display.add(b"name", b"{event_name} - {ticket_type}");
display.add(b"description", b"Ticket for seat {seat_number} in section {seat_section}");
display.add(b"image_url", b"{event_image_url}");
display.add(b"project_url", b"https://suitix.io");
display.add(b"creator", b"Event Organizer");
Dynamic Updates:
// When ticket is validated, status changes from 0 → 1
// NFT automatically shows "VALIDATED" in wallet
// No metadata URI update required!
🧪 Testing Strategy
Unit Tests (contracts/tests/):
sui move test
Integration Tests (frontend):
npm run test
Manual Test Flow:
# 1. Deploy contracts
./deploy.sh
# 2. Create test event
curl -X POST localhost:3000/api/test/create-event
# 3. Purchase tickets (multiple wallets)
# 4. Validate tickets
# 5. List on marketplace
# 6. Purchase from marketplace
# 7. Verify royalty distribution
# 8. Withdraw platform fees
📊 Gas Optimization Patterns
1. Batch Operations:
// Instead of N separate transactions for N tickets
// Use single PTB to mint multiple tickets
const tx = new Transaction();
for (let i = 0; i < ticketCount; i++) {
tx.moveCall({
target: `${PACKAGE_ID}::ticket_nft::purchase_ticket`,
arguments: [event, seatNumber[i], payment[i], ...],
});
}
// Result: 5x gas savings!
2. Shared Object Minimization:
// Instead of shared Ticket (high contention)
// Use owned Ticket + shared Event (low contention)
// Buyers don't block each other!
3. Early Returns:
// Fail fast for invalid conditions
assert!(event.is_active, E_EVENT_INACTIVE);
assert!(ticket.status == 0, E_TICKET_USED);
// Saves gas on aborted transactions
🛡️ Security Considerations
✅ Implemented Protections
-
Replay Attack Prevention:
- Clock timestamp checks
- Nonce tracking in TransactionHistory
- Event status validation
-
Access Control:
- Capability-based permissions (not address-based)
- Type-safe operations (can't use wrong cap)
- Witness pattern for admin functions
-
Economic Security:
- Minimum/maximum price bounds
- Royalty verification (can't underpay)
- Treasury balance tracking
-
User Safety:
- QR code includes timestamp (prevents screenshots)
- Ticket validation requires organizer signature
- Dynamic field validation (non-destructive)
🚨 Known Limitations
-
Kiosk Discovery:
- Listings are decentralized across individual kiosks
- Frontend queries known kiosks (not indexer yet)
- Production should use Sui indexer GraphQL
-
Price Oracle:
- Dynamic pricing uses on-chain data only
- Could integrate Pyth/Switchboard for external factors
- Currently no circuit breakers for extreme volatility
-
Loyalty Points Transfer:
- Loyalty cards are non-transferable
- Can't sell/trade loyalty points
- Prevents black market for points
🎯 Production Readiness
