[Campaign Category] Category Questions

Describe what makes your idea innovative compared to what has been previously launched in the market (whether by you or others).

This platform is innovative because it directly integrates invoice issuance with on-chain payments on the Cardano blockchain, supporting ADA and native tokens.

Unlike other projects, it combines user-friendly interfaces, automatic payment confirmations through smart contracts, and full auditability, making cryptocurrency payments accessible to businesses and freelancers without technical knowledge.

It also offers integration with platforms, creating a practical and real-world use case that drives adoption and utility of the Cardano ecosystem.

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

The platform's MVP will demonstrate end-to-end invoice issuance and management on Cardano, including PDF and on-chain formats, payments with ADA and native tokens, automatic smart contract confirmations, and transaction statements.

It will be accessible through a web interface, with a limited beta available to select freelancers for testing and feedback before public launch.

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

Success will be measured by concrete adoption and on-chain transactional activity. Key metrics include:

• Number of invoices issued by the platform
• Total volume of ADA transacted
• Number of active freelancers
• Number of hits to the website
• Number of Cardano Wallets conected
• Successful SmartContract confirmations

Additional metrics include on-chain tracking of payment settlement times, transaction auditability, and the use of API integration with ext. platforms.

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

Create a platform for issuing and managing invoices fully integrated with the Cardano blockchain, enabling:

• Invoice generation in PDF and on-chain formats;
• Direct payments in ADA and native Cardano tokens;
• Automatic payment confirmation via smart contracts;
• Immutable and auditable transaction history;
• API for integration with ERPs, CRMs, and marketplaces.

Differentiators

• Professional invoicing solution focused on Cardano;
• Native support for Cardano tokens and stablecoins;
• Extremely low transaction costs;
• Intuitive interface for businesses without blockchain experience.

[Your Project and Solution] Impact

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

The platform drives real-world adoption of ADA as a payment method while increasing the utility of native Cardano tokens. It strengthens Cardano’s presence in the digital business and freelancer market and fosters integrations with DeFi projects and Cardano stablecoins.

[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?

I have experience in blockchain development, project management, and SaaS platform delivery, ensuring high levels of trust and accountability. The project team will follow agile development practices, maintain transparent progress reporting, and use secure smart contract protocols.

Our team has previously been approved in 9 projects on Catalyst and all projects were successfully completed and with a project closure report containing all proof of delivery and 1 project under in development in Fund 11.

Feasibility will be validated through incremental milestones, including prototype testing, beta releases with selected users, and on-chain payment trials, ensuring the platform functions reliably before full public launch.

Our team is composed of developers, UX / UI, Marketing, SEO, Marketing, Business and we developed the largest media coverage platform Cardanofeed.com, with more than 1,000,000 monthly visits and also the largest & Cardano Ecosystem project directory (approximately 1,200+ projects) and the Governance Space platform.
