Please describe your proposed solution

Every DeFi application relies on a set of critical parameters that determine its efficiency and safety.

For example, lending protocols often use simple functions to calculate interest on borrowed assets. However, these simplistic approaches can lead to capital inefficiency or high-risk environments that endanger user funds. A common issue is the over-collateralization requirement, where borrowers must deposit 200% of the loan value. While this reduces risk, it is inefficient—some assets may only need 150% collateral, while others might need more, depending on market conditions.

Similarly, mispricing the cost of capital, such as setting interest rates too high or too low, can result in reduced revenues for the protocol.

Building accurate simulations to model these dynamics is complex, as it involves sophisticated market analysis. This is where Xerberus Risk Ratings come in—they provide a solid foundation for building precise simulations.

We propose an open-source software solution that enables developers to input their DeFi applications and simulate their protocols under various market scenarios. By doing so, they can determine the optimal parameters for their specific use case based on current market conditions.

This tool will enhance the development of DeFi protocols on Cardano, helping builders to optimize capital efficiency and security by leveraging Xerberus Risk Ratings. It will ultimately lead to more robust and reliable DeFi applications within the Cardano ecosystem.

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

Cardano was built with the vision of becoming the global financial system, and we've made significant strides toward realizing that goal.

Now, it's time to professionalize our ecosystem to the point where our applications surpass even the most advanced ones in the crypto space in terms of risk management and capital efficiency.

By developing applications that are highly resilient to stress and optimized for revenue generation, we can create a more attractive environment for both investors and builders. This, in turn, will drive sustainable growth for the ecosystem.

Our decision to open-source this simulation tool is central to this vision. By doing so, we lower the barrier for builders to create capital-efficient dApps, adding fertile ground for innovation across the ecosystem.

Developers will be able to fork the project from our GitHub repository and utilize educational videos that guide them on how to use the application to simulate their own dApps effectively.

Creating a simulation tool can be complex, so an intuitive and user-friendly interface is crucial to make it easier for developers to navigate and use the simulation. As part of this milestone, we will design wireframes, which will be submitted as a Figma file, showcasing the fully designed simulation engine. These wireframes will allow Catalyst reviewers to understand how end users will interact with the simulation tool. Additionally, we will provide a video explanation of the engine to offer context and clarity, as some aspects of the simulation may be challenging to grasp without guidance.

Milestone 4: Milestone 4: Prototype

In this milestone, we will integrate all components to deliver the first version of the simulation in a production environment. Reviewers will have access to the development environment and be able to run an initial simulation. While the prototype may have some limitations and bugs, these will be clearly identified when submitting the milestone. This early version will demonstrate the core functionality of the simulation, marking a significant step toward the final product.

Milestone 5: Milestone 5: Production

In this final major milestone, we will deploy the simulation engine into a full production environment, accessible via a Xerberus URL. This will allow anyone to simulate a DeFi protocol without the need to fork the GitHub repository or access a development environment. The production environment will be a user-friendly platform, easily accessible without login requirements, ensuring open access to the simulation engine for the broader Cardano ecosystem.

Final Milestone: As part of this final milestone, we will submit a comprehensive Catalyst Project Report. This will include a fully cleaned-up and organized GitHub repository, ready for developers to fork and use. Additionally, we will provide a link to a YouTube playlist with detailed tutorial videos explaining how to use the protocol risk simulation engine. These resources will ensure that developers have everything they need to effectively leverage the simulation tool.

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

Cardano is designed to be the future of global finance, and achieving widespread adoption requires enabling builders to create the most advanced protocols in the crypto industry. Xerberus has a proven track record of building for the community, and by developing an open-source model that enhances capital-efficient DeFi, we believe this project will have ripple effects throughout the entire Cardano ecosystem.

Regarding our costs, we pay standard wages that reflect the cost of living in cities like London, where our operation is based. The rates we have set are aligned with typical freelance and professional rates in our industry, ensuring that we provide the highest quality of quantitative expertise to the Cardano community while operating on a cost basis.

We have assumed ADA to be priced at $0.50, which is conservative compared to its current value at the time of writing. While ADA's price may rise during a bull run, we need to plan conservatively as we are hiring real people with families and ongoing commitments. Should ADA's value exceed our price assumption, we will reinvest any additional funds into improving the application by enhancing design quality and user experience through additional development hours.
