[SOLUTION] Please describe your proposed solution

The problem we’re addressing is that current Cardano libraries don’t offer an easy way for developers to use Hydra’s Layer 2 scaling, which makes it harder to build DApps that can handle high transaction volumes. As the team behind the Kuber Library, we see an opportunity to solve this by adding Hydra transaction support directly into Kuber. This will make it much easier for developers to tap into Hydra’s capabilities.

Our approach is simple: by integrating Hydra directly into Kuber, we lower the technical barriers for developers. They won’t need to learn new tools or complex protocols to use Hydra for scaling their DApps. This way, developers can focus on building scalable applications without worrying about the technical complexities of Hydra.

Our project is aimed at developers in the Cardano ecosystem who need better scalability for their DApps. While Kuber isn’t widely used yet, adding Hydra support could make it much more appealing and useful, driving greater adoption.

We’ll prove our impact by tracking how many developers use Kuber for Hydra-related projects and gathering feedback from them. Since Kuber is open-source, the community will be able to see and contribute to the project, ensuring transparency and collaboration.

What’s unique about our solution is that it keeps things simple for developers. Instead of learning something entirely new, they’ll be able to use Hydra through Kuber, which they may already be familiar with. This makes it easier to build scalable DApps, which in turn helps the entire Cardano ecosystem grow and handle larger user bases effectively.

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

Impact on the Cardano Community

Our project will have a significant positive impact by making it easier for developers to integrate Hydra’s Layer 2 scaling solution into their DApps. This will lead to the development of more scalable applications that can handle higher transaction volumes, ultimately benefiting users and expanding Cardano’s capacity for growth.

Measuring Impact:

• Quantitative Metrics: We will track the adoption of the Kuber Library with Hydra support by monitoring downloads, usage statistics, and the number of DApps utilizing the library for Hydra-related scaling.
• Qualitative Metrics: We will gather feedback from developers through community channels, GitHub issues, and surveys to understand their experience and any improvements they need.

Value to the Cardano Community: The success of this project will provide developers with an accessible, user-friendly tool to build scalable DApps, reducing friction in development and fostering innovation. This will enhance Cardano’s ability to support a growing user base and diverse applications, making the ecosystem more robust and efficient.

Sharing Outputs:

• We will release the Hydra-integrated Kuber Library as an open-source project on GitHub, allowing developers to freely use, modify, and contribute to it.
• We will engage with the community through Cardano forums, social media, and workshops to demonstrate the tool, collect feedback, and encourage collaboration.
• All updates, improvements, and learnings from the project will be shared publicly to maximize transparency and community involvement.

In summary, by simplifying Hydra integration, this project empowers developers, strengthens the Cardano network, and promotes scalable DApp development, contributing to the long-term growth and success of the ecosystem.

[CAPABILITY & 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?

Capability & Feasibility

We believe we are well-equipped to deliver this project with high levels of trust and accountability due to our extensive experience and proven track record in Cardano development. As the developers of the Kuber Library, we have a deep understanding of its architecture and are uniquely positioned to integrate Hydra support effectively.

Our team has previously worked on several significant projects:

• KuberIDE: A browser-based Plutus Integrated Development Environment (IDE) that simplifies smart contract development on Cardano.
• Cardano Mempool Explorer: A tool for exploring Cardano's mempool, successfully completed under a previous Catalyst proposal.
• GovTool: An application designed to facilitate governance processes within the Cardano ecosystem.
• Chang Hard Fork Testing: We conducted extensive testing during the Chang hard fork, ensuring network stability and performance.

We have also been awarded two Catalyst proposals in the past:

1. Mempool Explorer: Successfully completed and delivered to the community.
2. Cardano Autonomous Testing: Currently nearing completion, demonstrating our ongoing commitment and reliability.

Our extensive knowledge in Cardano development and Plutus smart contract programming makes us confident in our ability to deliver this project effectively. We understand the challenges involved in integrating Hydra support and are prepared to address them.
