[Proposal Summary] Problem Statement

What is the problem you want to solve?

Raffles and lotteries are powerful growth and fundraising tools. But without credibly trustless randomness, transparent fund flows, and a smooth UX, creators and charities avoid them.

[Campaign Category] Category Questions

Describe what makes your idea innovative compared to what has been previously funded (whether by you or others).

1. 🤝🏻 Decentralized Trust: RAFFLEIZE uses a commit and reveal scheme as source of randomness in winner selection.
2. 💧 Enhanced Liquidity: Owners can easily trade or sell their stakes or participation rights on various platforms. This increases the assets' marketability and value.
3. 🔁 Recursive Raffle Opportunities: (Raffles of Raffles) Owners can create raffles for their raffle stakes or tickets, adding a recursive layer of engagement. This not only multiplies the opportunities for users to engage with the platform but also introduces a novel concept of raffle chains.

Describe what your prototype or MVP will demonstrate, and where it can be accessed.

The https://www.raffleize.art will include along with the classic raffles:

1. Crowdfounding Raffles: service that aims to enable anyone to raise enough money needed for a project. The project can be a direct donation to a charity, an academic or business plan, or anything else the creator can convince people to contribute. (similar to https://ergoraffle.com/ );
2. Pot lotteries where ticket sales automatically accumulate into a prize pool secured by smart contracts.

Describe realistic measures of success, ideally with on-chain metrics.

Primary KPIs (first 6 months after mainnet launch):

• ≥ 150 raffles created (all types); ≥ 15,000 tickets sold;
• ≥ 2,500 unique participating wallets;
• ≥ 10 verified charities onboarded; ≥ ₳250k total raised for charities;
• 99.5% app uptime;
• less then 1% failed tx rate (excluding wallet/user cancelations).

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

Without a trustworthy, easy raffle tool, Cardano misses out on everyday activities that could bring in new users, raise funds for causes, and generate transactions.

We will upgrade Raffleize (https://raffleize.art) from a working Preview app into a mainnet‑ready platform with:

1. Fair raffles using proven on‑chain randomness;
2. Crowdfunding raffles that raise funds for projects or causes;
3. Pot lotteries where the ticket pot automatically goes to the winner.
4. Improve the raffle builder UX for no-code setup.
5. Analytics dashboards and public campaign pages.

[Your Project and Solution] Impact

Please define the positive impact your project will have on the wider Cardano community

Who benefits:

• Creators and NFT communities seeking transparent raffles.
• Organizers raising funds for projects or events.
• Everyday users engaging in fun, fair, on-chain activities.

Each raffle or lottery creates multiple on-chain transactions, onboarding new wallets and generating adoption momentum.

[Your Project and Solution] Capabilities & Feasibility

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?

Track Record: Live, proven prototype already on Cardano Preview : https://raffleize.art/

I will be building on an existing codebase—reducing risk, cost, and delivery time—while adding high-impact features that boost ecosystem activity.

[Final Pitch] Budget & Costs

Please provide a cost breakdown of the proposed work and resources

This budget reflects only the development costs required to implement the new crowdfunding and pot lottery features, upgrade the frontend, and deploy the platform to mainnet.

Crowdfunding raffles dev: ₳5,500

Pot lottery dev: ₳5,500

Frontend & launch: ₳4,000

[Final Pitch] Value for Money

How does the cost of the project represent value for the Cardano ecosystem?

As Bitcoin liquidity flows into Cardano via cross-chain bridges, security-minded BTC users will seek provably fair dApps. Raffleize’s commit-and-reveal scheme offers Bitcoin-grade transparency, making it a natural gateway for these users to engage with Cardano—boosting adoption and transaction volume.

Raffleize directly drives new on‑chain activity by making it simple for anyone—creators, communities, or charities—to launch raffles and lotteries on Cardano.

Each event generates multiple transactions (creation, ticket purchases, draw, payout) and introduces new users to Cardano wallets and dApps.

Crowdfunding raffles help projects raise funds transparently, showcasing Cardano’s capabilities for secure, open fundraising.

Pot lotteries add an engaging, gamified use case that encourages recurring participation.

By being fully open source, Raffleize also becomes a reusable building block for other developers, multiplying its adoption impact across the ecosystem.
