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

We are democratizing OTC trades in key sectors like real-estate, hospitality, and aviation by decentalizing access. Our Cardano mirgation will bring momentum, market validation, and global reach to the ecosystem:

• Cardano-native wallet and onboarding, bring merchants to Cardano

• Trustless OTC desk & swaps with ADA: new DeFi model

• Cardano Pay API for merchants with auto FX: 10K+ transactions monthly

• Smart Treasury with Cardano DeFi yield: increasing TVL

• On-chain affiliate portal with ADA rewards: customer adoption & reach

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

The MVP will launch a swap engine on mainnet and a OTC desk on Cardano mainnet. It will be accessible via the WTC Pay website and as a Web3 payment solution.

• The MVP will demonstrate how the Cardano Blockchain can be a go -to hub for decentralized OTC trading and swaps in exciting new sectors
• Our MVP will strengthen Cardano's value to key sectors

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

• ADA transaction volume within the 10,000s p/month (minimum, based on current rates) from real-world merchant and OTC flows
• New onchain data from real world sectors: overview of onchain transactions (as part of Milestone reports) broken down by country
• Will bring 4 new blue-chip enterprise clients that we are currently in negotiations with into the Cardano ecosystem.
• Four new innvative DeFi suite products developed and launched on Cardano
• Decentralized DAO governance model to be explored on Cardano

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

High-value industries require compliant, fast, trustless payment solutions, yet current providers are slow, centralized, and lack Cardano-level scalability. Migrate WCT Pay’s proven, revenue-generating Web3 payments infrastructure onto Cardano to unlock true decentralization, enterprise-grade DeFi integration, and ADA adoption.

WCT Pay is a live, revenue-generating payments business serving high-value global clients and processing substantial transaction flows. We are ready to take this Web3 - this is why we are now seeking funding from the Cardano ecosystem to move this business fully on-chain — migrating operations to the Cardano network and transitioning WCT Pay into a Web3-native payments solution.

Our current client portfolio includes some very well respected international brands such as Cebuana Lhuillier (Philippines) and Marriott Hotels via their Travel & Leisure division for timeshare real estate — each representing significant transaction volumes and industry influence. By moving WCT Pay’s existing infrastructure onto Cardano, we will not only secure these flows for the Cardano network, but also deliver strong brand association with household names.

We are offering Cardano an established operation with momentum, market validation, and global reach.

Funding will accelerate our technical migration, smart contract integration, and product evolution into a fully Web3-enabled platform. The result will be higher transaction throughput for the Cardano network, increased adoption from mainstream sectors like travel, leisure, and remittances, and valuable exposure through these marquee partnerships.

We will develop:

Cardano-native wallet and onboarding, Trustless OTC desk & swaps with ADA, Cardano Pay API for merchants with auto FX, Smart Treasury with Cardano DeFi yield, On-chain affiliate portal with ADA rewards.

[Final Pitch] Value for Money

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

WCT Pay delivers immediate and measurable value to Cardano by:

• Anchoring real-world commerce to ADA transactions.
• Leveraging proven adoption to accelerate Cardano enterprise penetration.
• Providing a replicable model for future Cardano-native payment platforms.

WCT Pay’s migration to Cardano creates both immediate and long-term benefits for the ecosystem:

1. Real-World ADA Utility – High-value OTC trades, merchant payments, and treasury operations settled directly on Cardano will significantly increase on-chain ADA transaction volume and visibility.
2. Enterprise Adoption of Cardano – Blue-chip Client #1 (industry vertical #1), Bluechip Client #2 (industry vertical #2), and others will actively transact on Cardano, demonstrating blockchain’s readiness for regulated, enterprise-grade commerce.
3. Expansion of Cardano’s DeFi Ecosystem – Smart Treasury integration will bring new liquidity pools, staking opportunities, and yield strategies to Cardano-native DeFi protocols.
4. On-Chain Governance & DAO Engagement – The DAO structure will engage the Cardano community in platform decision-making, tokenomics design, and revenue-sharing models.
5. Integration with Cardano Identity Solutions – Potential use of Atala PRISM for merchant and partner KYC, showcasing Cardano’s identity tech in real-world payments.
6. Developer Ecosystem Growth – The open-source Pay API and merchant integration kits will enable third-party developers to build payment apps and extensions on top of Cardano.
7. Catalyst Project Showcase – WCT Pay will serve as a flagship example of how Catalyst-funded projects achieve commercial adoption, attracting new proposals and funding to the ecosystem.
8. Cross-Industry Cardano Presence – From aviation and luxury goods to gaming and maritime trade, Cardano will gain visibility in industries not currently associated with blockchain adoption.

WCT Pay offers exceptional value for the Cardano ecosystem by delivering:

1. Proven Market Traction – Migration builds on $20M OTC volume, 48 active onboarding clients, and 10,000+ completed transactions — ensuring funds are invested in a solution with established demand.
2. High-Impact Use Cases – Direct integration into industries such as aviation, luxury real estate, gaming, and maritime trade ensures Cardano gains visibility in multi-billion-dollar sectors.
3. Catalyst Leverage Effect – Funding will accelerate migration, unlocking multiple revenue streams (merchant fees, OTC desk, treasury yields) that will sustain the platform beyond the funded period.
4. ADA Demand Creation – Merchant payments, OTC settlements, and staking pools will drive direct ADA usage, increasing liquidity and transaction volume on Cardano.
5. Global Enterprise Showcase – Serves as a reference project for Cardano’s ability to support regulated, enterprise-grade payments infrastructure.
6. Developer Enablement – Open-source APIs and integration kits will invite third-party innovation, creating secondary value in new apps, tools, and services.
7. Brand Positioning – Positions Cardano as a leader in decentralized, compliant, enterprise-ready payment rails, helping attract future partnerships, developers, and investors to the ecosystem.
8. Sustainable ROI – By targeting high-value clients and offering scalable infrastructure, the project delivers outsized impact relative to the requested funding.
