No dependencies

[GENERAL] Will your project’s output/s be fully open source?

No

[GENERAL] Please provide here more information on the open source status of your project outputs

The backend of Klaatoo wallet is non-public. The integration with Cardano will be merged into the backend, thus the output of the project is private. The SDKs for Swift, Kotlin and JS could be published, but that has limited use since those SDK support only address generation, transaction construction and signing.

[SOLUTION] Please describe your proposed solution.

Klaatoo is a multi-currency wallet that allows users to store, receive and send multiple cryptocurrencies from a single wallet rather than needing a separate wallet for each currency. Some of the key features of Klaatoo are:

1. Support for Major Cryptocurrencies - Klaatoo provides access to Bitcoin (WIP), Ethereum (WIP), Ripple (WIP), DOGE (WIP), Atom, iNAE as well as ERC-20 and other tokens under one wallet. Adding Cardano support is the target of the current proposal.
2. Private Keys Management - Klaatoo provides a unified interface to manage the private keys securely for the different currencies instead of having to handle keys individually per currency wallet. 
3. Exchange Services - Klaatoo provides seamless integration with Bitforex exchange allowing users to easily swap between cryptocurrencies within the wallet itself (WIP).
4. Variety of Addresses - Klaatoo generates and maintains receiving addresses for all supported coins and makes them accessible to users all accessible from the same wallet account. 
5. Transaction Histories - Users can view past transaction details across currencies in the same window rather than switch between currency-specific histories.
6. Accessibility - Multi-currency wallets are available across devices as mobile, desktop and web apps providing ubiquitous access and easy use.

By supporting multiple major cryptocurrencies in one place, Klaatoo enhances the overall user experience and convenience for both storing as well as transacting with digital currencies.

Klaatoo wallet is available to test and play with. The current version of Klaatoo is up and running. You can find it on both Google Play and the App Store:

• Google Play: Klaatoo on Google Play
• App Store: Klaatoo on App Store

Status of currencies support:

• Available:
• iNAE coin (iNAE blockchain) - available,
• Atom coin (Cosmos blockchain) - available,
• Work in Progress:
• BTC (Bitcoin blockchain)
• ETH (Ethereum blockchain)
• DOGE (Doge blockchain)
• TRON (Tron blockchain)
• XRP (Ripple blockchain)

After completing this proposed project Klaatoo will support ADA, the native coin of Cardano.

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

In what way will the success of your project bring value to the Cardano Community?

The availability of multicurrency Klaatoo wallet can bring significant value to the Cardano community in several ways:

1. Convenience and Accessibility: Klaatoo allows users to manage various cryptocurrencies, including ADA and Cardano's native tokens, alongside other popular tokens and coins. This consolidated approach offers convenience by enabling users to store, send, receive, and manage multiple digital assets within a single platform. This streamlines the user experience and removes the hassle of juggling multiple wallets for different currencies.
2. Enhanced Adoption: By supporting multiple currencies, Klaatoo can attract users from diverse crypto communities. For Cardano, this means becoming more accessible to individuals who hold different cryptocurrencies. It broadens the user base and introduces Cardano to those who might not have considered it before, potentially leading to increased adoption and usage of the ADA token.
3. Interoperability: Klaatoo encourages interoperability among different blockchain ecosystems. Users can seamlessly interact with various tokens and coins, fostering a more interconnected crypto landscape. This aligns with Cardano's vision of interoperability and cross-chain communication, potentially facilitating collaborations and integrations between Cardano and other blockchain projects.
4. Diversification and Investment: Offering multicurrency support allows Cardano community members to diversify their investment portfolios within the same wallet. Users can easily diversify their holdings, managing different assets in one place. This flexibility encourages investors to explore and hold ADA alongside other cryptocurrencies, potentially strengthening Cardano's position in the broader market.
5. User Preference and Flexibility: Many users prefer having a single application to manage all their digital assets. Klaatoo caters to this preference, offering a familiar and comprehensive interface for users to monitor and control their various holdings, including ADA, thereby enhancing user satisfaction and engagement within the Cardano ecosystem.

Overall, the availability of Klaatoo not only simplifies the user experience but also promotes inclusivity, interoperability, and broader acceptance of Cardano within the larger cryptocurrency community.

How will you measure this impact?

Measuring the impact of Klaatoo on the Cardano ecosystem involves assessing various metrics and indicators that demonstrate changes or advancements attributable to their presence.

1. User Adoption and Growth: Analyze the increase in the number of users utilizing Klaatoo within the Cardano ecosystem. This could involve tracking wallet downloads, active users, or the percentage of ADA holders using Klaatoo compared to single-currency ones.
2. Transaction Volume and Activity: Evaluate the transaction volume of ADA within Klaatoo compared to dedicated ADA-only wallets. Monitor the frequency and volume of ADA transactions occurring within these wallets to understand their usage patterns.
3. Token Diversity: Measure the variety of tokens being held within Klaatoo. Analyze the types and quantities of other cryptocurrencies stored alongside ADA. An increase in diverse tokens held in these wallets might indicate a broader acceptance of Cardano among users who hold multiple assets.
4. Community Engagement: Assess community sentiment and engagement regarding the introduction of Klaatoo. Gather feedback through surveys, forums, or social media platforms to understand user experiences, preferences, and suggestions related to using these wallets within the Cardano ecosystem.

By combining these measurements, it becomes possible to gauge the tangible effects of Klaatoo on the Cardano ecosystem, helping to determine their effectiveness in driving adoption, diversification, user engagement, and ecosystem expansion.

How will you share the outputs and opportunities that result from your project?

Once the project is completed, users can download the Klaatoo wallet with Cardano integration via the Google Play Store and Apple AppStore. For existing users, updating Klaatoo will unlock access to the latest Cardano developments and integration.

Moreover, we intend to disseminate these advancements and integrations extensively through our social media channels, in-wallet notifications, subscriber newsletters, forthcoming blog posts, and by crafting a dedicated webpage tailored specifically for Cardano on our website. Our commitment extends to forging lasting partnerships, collaborating on ongoing integrations of Cardano native tokens within Klaatoo, and executing cross-platform announcements and marketing initiatives.
