Please describe your proposed solution

Our proposed solution is to develop a comprehensive, open-source multi-sig wallet management tool for Cardano, built using Vue.js. This tool addresses the shortcomings of existing solutions like RoundTable and SummonDAO by providing a more flexible, cost-effective, and feature-rich alternative. Key features include:

1. Multi-Sig Wallet Management: Users can easily import and manage multi-sig wallets from RoundTable and SummonDAO. This allows for seamless transition and consolidation of wallets in a single platform.
2. Cost-Effective Deployment: We will make the tool affordable by allowing users to choose their backend infrastructure. Rather than relying on an expensive Cardano GraphQL instance, the tool will be designed to work with Blockfrost and/or Ogmios+Kupo, both of which offer free or low-cost options. This reduces hosting costs and makes the tool accessible to a wider audience.
3. Open-Source and Community Driven: The project will be fully open-source, allowing the Cardano developer community to contribute and improve the tool over time. The codebase, documentation, and setup guides will be made available on GitHub, ensuring transparency and ease of access.

By delivering a versatile, open-source multi-sig wallet management tool, we aim to empower the Cardano ecosystem with a cost-effective solution for secure and flexible transaction management and governance.

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

Our project will have several positive impacts on the wider Cardano community:

1. Increased Accessibility to Multi-Sig Wallets: By providing an open-source and cost-effective tool, we lower the barrier to entry for users and projects needing multi-sig functionality. Users won’t need to rely on costly infrastructure, such as hosting a Cardano GraphQL instance, to manage their wallets, making it easier for small projects, DAOs, and individuals to leverage multi-sig security.
2. Revitalization of Under-Maintained Tools: Existing tools like RoundTable are no longer actively maintained, leaving a gap in the ecosystem. By enabling users to import and manage their RoundTable and SummonDAO wallets, we offer a unified and up-to-date platform, breathing new life into under-maintained services.
3. Lower Hosting and Maintenance Costs: Our solution is designed to be lightweight and scalable, utilizing free or low-cost backends like Blockfrost and Ogmios+Kupo. This significantly reduces the technical and financial burden on users and developers hosting multi-sig wallets, making decentralized security more accessible to a wider audience.
4. Open-Source Contribution and Innovation: By being fully open-source, we foster collaboration within the Cardano developer community. Our project will serve as a foundation for other developers to build on, innovate, and contribute to the ecosystem’s growth. This will also drive continuous improvement of the tool as new features and updates are integrated by the community.

Overall, this project strengthens Cardano’s decentralized infrastructure, improves wallet security, and supports the network’s governance, all while providing affordable, scalable solutions to a wider range of users.

The key dependencies for this project include:

1. Blockfrost or Ogmios+Kupo Stack: These provide essential blockchain data access for managing multi-sig wallets without the need for a costly Cardano GraphQL instance. Blockfrost is a widely used API service that abstracts Cardano node interactions, while Ogmios+Kupo is an efficient, lightweight alternative for those looking for a more customizable backend setup. This makes it vital for ensuring cost-effective, scalable access to Cardano data for wallet management.
2. <https://blockfrost.io/>
3. <https://github.com/CardanoSolutions/ogmios>
4. <https://github.com/CardanoSolutions/kupo>

These dependencies are vital as they provide cost-effective, reliable, and scalable infrastructure that makes multi-sig wallet management feasible and affordable for the broader Cardano community.

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

The cost of the project represents significant value for money for the Cardano ecosystem due to several key factors:

1. Filling a Critical Gap:

This project addresses a pressing need for a comprehensive, cost-effective multi-sig wallet management tool. Current solutions either lack ongoing maintenance (RoundTable) or charge fees for usage (SummonDAO). By offering an open-source, low-cost alternative that integrates both existing and enhanced multi-sig features, this tool will serve a large portion of the Cardano community, especially smaller DAOs, developers, and users seeking affordable multi-sig solutions.

2. Long-Term Use and Sustainability:

The tool will be fully open-source, meaning it can be freely used, modified, and maintained by the community long after the initial project is completed. This ensures that the cost of development benefits the entire ecosystem over the long term without additional recurring costs for users.

3. Cost-Effective Hosting:

By leveraging free or low-cost infrastructure options such as Blockfrost and Ogmios+Kupo, the tool drastically reduces the cost of hosting compared to alternatives requiring expensive infrastructure like Cardano GraphQL. This makes multi-sig wallet management affordable for a wider audience, providing value by reducing overhead for users and DAOs.

4. Boosting Cardano’s Decentralization:

By making multi-sig wallet creation and management more accessible, the project enhances the security and decentralization of governance within the Cardano ecosystem. This encourages more projects and DAOs to adopt secure multi-sig solutions without high costs, contributing to the overall growth and stability of the network.

5. One-Year Hosting and Maintenance:

The budget also includes one year of hosting, bug fixes, and maintenance, ensuring that users have a fully operational tool with ongoing support at no extra cost. This upfront maintenance guarantees the tool remains stable and functional as more users adopt it.

In summary, the 200,000 ₳ budget is a strong investment in the long-term health of the Cardano ecosystem, providing essential infrastructure that supports decentralization, governance, and user security at minimal ongoing cost.
