Describe your established collaborations.
This proposal is a deep collaboration between:
Anvil is a Cardano-native development agency with 4+ years of full-time chain experience and hundreds of completed on-chain projects, including DeFi, NFTs, staking, and custom infrastructure. We are a commercial partnerof the Cardano Foundation in the United States, and pride ourselves in producing professional quality products, dApps, and tooling.
Examples include:
For Sellout, Anvil has designed and implemented the full Cardano ticketing backbone: event policies, royalty tokens, master manifest NFTs, ticket NFTs, transfer flows, and attendance reconciliation logic. Anvil is responsible for architecture, smart contracts, and all Cardano infrastructure integration.
Sellout is a Web2 ticketing and event management platform founded in 2017 with a mission to “elevate the organizer, protect the fan, support the artist.”
To date, Sellout has:
Sellout brings:
Sellout already powers ticketing for venues such as Live From The Divide and Yellowstone Club. These existing relationships will be among the first adopters of Cardano-native NFT ticketing.
The first major activation of this stack is the Yellowstone Club 2026 concert series, where several thousand high-value tickets (priced between ~$400 and ~$8,000) for headline artists including Tiësto and Dave Matthews Band are planned to be issued using the new Cardano infrastructure. Based on current projections, this single collaboration alone is expected to represent $6M+ in ticket revenue moving on-chain.
Together, Anvil and Sellout combine:
to deliver one of the first enterprise-grade NFT ticketing systems on Cardano backed by an existing, profitable Web2 business.
Describe funding commitments.
By December 1st, the Phase 1 stack will be live in production, and Sellout will be demoing real events, tickets, and attendance flows on Cardano.
This means:
What Catalyst is funding
This proposal does not seek retroactive funding. Catalyst funds will be used exclusively for Phase 2, which builds on the completed MVP:
Sellout and Anvil are committed to delivering Phase 2 regardless of Catalyst; however, without Catalyst, development would be significantly slower and narrower in scope, and the Cardano community would lose the opportunity to:
Catalyst funding amplifies and accelerates a transition that Sellout is already funding and executing with its own resources.
Describe your key performance metrics.
Our KPIs are centered on verifiable on-chain activity, real-world adoption, and ecosystem growth. Final figures will be validated with Sellout prior to review, but the structure of the metrics will remain as follows.
We will track the following transaction-level metrics on Cardano:
User & Wallet KPIs
At launch, we will begin to migrate Sellout's 200,000+ existing users, on-chain. This will continue over the broader rollout as Sellout migrates its ticketing flows. This proposal’s initial 6-12 month window will include a defined subset of that base, with explicit targets agreed with Sellout.
Adoption KPIs (Organizers, Venues, Artists)
Indicative Targets - To Be Confirmed with Sellout
These will be refined with Sellout leadership and published before Community Review, but indicative targets are:
Q1 2026
Within 12 months of Phase 2 completion
These KPIs are:
Please describe your proposed solution and how it addresses the problem
Despite billions flowing through the ticketing industry each year, the system still fails the people who matter most - fans, artists, and organizers. The problems are structural, not cosmetic:
Phase 1: The Foundation (Already Built)
Sellout and Anvil built the entire on-chain ticket creation + event infrastructure in Phase 1, fully funded by Sellout with zero Catalyst support.
This includes:
This foundation is already powering real events. Sellout is debuting the system at the Yellowstone Club 2026 concert series, featuring major artists including Tiësto and Dave Matthews Band, with several thousand tickets priced between $400 and $8,000.
This alone represents ~$6M in ticket revenue going fully on-chain.
Phase 2: Building the System That Changes Ticketing Forever
This proposal focuses on Phase 2, which brings the marketplace and Web3-native functionality to life:
Secondary Marketplace
Royalty enforcement for artists & venues
Fan-to-fan transfers without scalping
Transparent, verifiable attendance data
Wallet creation for every Sellout user (200k+)
True digital ownership of every ticket
Resale controls & anti-fraud validity checks
Cross-platform portability and third-party integrations
Where Phase 1 built the foundation, Phase 2 frames the rest of the building. The marketplace, the rules, the protections, the transparency, and the user experience that finally fixes everything people hate about tickets.
Every concert, every venue, every fan.
Every ticket becomes a real asset, backed by Cardano.
Why This Approach Works:
Because it solves the root problems - not the symptoms - by rebuilding ticketing as a verifiable, ownable, transferable digital asset rather than a glorified barcode.
Our approach:
Why Cardano Is the Right Chain
The strengths of the eUTXO model directly support fair, trustable ticketing:
Cardano is the only chain that can deliver Web2-grade reliability with Web3-grade guarantees. This is what Sellout has been looking for since the founding of the company.
Please define the positive impact your project will have on the wider Cardano community
This project turns Sellout’s existing ticketing business into sustained Cardano activity:
Net effect: Cardano becomes the chain behind real concerts, festivals, and live events-not just DeFi and NFTs. The ticketing market is a race that has not been won yet, and we are confident in our ability to win it.
Impact on fans
Impact on artists & organizers
Impact on developers
What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?
Why this team can deliver
Phase 1 of this system (event creation, ticket minting, transfer, and attendance on Cardano) is already built, integrated into Sellout, and going live on mainnet around Dec 1. Phase 2 extends a working pipeline rather than inventing a new one.

Please provide a cost breakdown of the proposed work and resources
The total requested budget of 700,000 ADA covers the complete development, integration, and launch of Phase 2 of the Sellout x Anvil Cardano ticketing platform. This includes the marketplace, royalty enforcement, resale rules, mobile-first UX, and full mainnet deployment.
The budget is divided into four execution categories:
1. Marketplace Architecture & Resale Design - 150,000 ADA
This includes the high-level blueprint for:
This stage defines the rules and structure that power all Phase 2 functionality.
2. Marketplace Core Development (Testnet + Mainnet) - 320,000 ADA
This represents the majority of the engineering work and delivers the functional marketplace.
3. Organizer Tools, Visualizations & Support Workflows - 150,000 ADA
These tools make the marketplace functional and accessible to real venues and artists.
4. Public Launch, Marketing Amplification & Catalyst Reporting - 80,000 ADA
This funds:
Sellout’s marketing and distribution channels directly amplify Cardano adoption across a mainstream audience.
Total: 700,000 ADA
Duration: 8 Months
USD PEG: $.40
All requested funds are allocated exclusively to Phase 2 development and launch.
No retroactive funding is included.
Sellout has fully funded Phase 1 independently.
How does the cost of the project represent value for the Cardano ecosystem?
This proposal delivers exceptional value to Cardano for three reasons:
1. Real Adoption From a Real Business
Sellout is migrating its entire ticketing platform to Cardano, bringing an existing 200,000+ user base and a mature Web2 revenue engine on-chain. This is immediate, verifiable onboarding-not hypothetical growth.
2. High-Volume, Recurring On-Chain Activity
Every event generates mints, transfers, resales, and attendance updates.
The Yellowstone Club 2026 concert series alone represents $6M+ in ticket volume fully executed on Cardano. This is sustained, compounding transaction flow.
3. Cardano Becomes the Chain That Fixes Ticketing
Phase 2 enables fair resale, royalty enforcement, and anti-scalping rules-problems that affect millions of consumers. Cardano becomes the backbone of a real-world, high-trust ticketing system used by major venues and artists.
Why This Is Worth Funding
Catalyst accelerates a transition Sellout is already committed to making.
For 700,000 ADA, the ecosystem gains:
This is one of the highest-impact, lowest-risk proposals Catalyst can fund-because the system already works, the clients already exist, and Cardano becomes the chain powering live events.
