[SOLUTION] Please describe your proposed solution

We created TyphonJs, the first open-source pure js wallet library for Cardano, with funding from Fund 6 of the Catalyst. TyphonJs provides features for implementing Cardano address, transaction serialization, signature, and transaction construction capabilities. The use cases for it are effectively unlimited because it is also compatible with browsers. It is useful for creating wallets, DApps, and many other things. Notably, the TyphonJs library has been adopted by Ledger Live to provide support for Cardano.

TyphonJs is written in typescript, making it easier and faster to upgrade to the forthcoming hard fork and any future important modifications.

The Cardano network will see significant upgrades as a result of the Chang hard fork, including dRep reg, dRep delegation, Governance action etc. We will upgrade TyphonJs to accommodate the changes in the hard fork so that developers can use TyphonJs to extend Conway support in their projects.

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

TyphonJs, as a TypeScript-based, browser-compatible low-level implementation of the Cardano wallet library, addresses several aims and challenges within the Cardano ecosystem.

1. Increased Developer Adoption and Productivity: Upgrading TyphonJs will result in increased developer adoption and productivity. TyphonJs enables developers to smoothly integrate Cardano functionality into their projects by providing a lightweight, developer-friendly library. This will bring more developers to the Cardano ecosystem and encourage innovation.
2. Enterprise-level and Commercial Projects: TyphonJs's developed features make it appealing for enterprise-level and commercial projects. TyphonJs provides a solid foundation for organisations looking to harness Cardano's capabilities in their solutions by providing a dependable and feature-rich wallet library. This creates opportunities for partnerships and collaborations, propelling Cardano's growth and adoption in the business world.
3. Major Project Integration: TyphonJs has already been utilised in high-profile projects such as Ledger Live and Minswap. This integration demonstrates the importance and trust that these projects have in TyphonJs, confirming its status as a trusted and extensively used library within the Cardano ecosystem. This not only demonstrates TyphonJs' potential but also invites additional users and developers to the Cardano community.

The enhanced TyphonJs library is expected to result in increased developer participation and a stronger ecosystem. It will attract more developers, drive innovation, and broaden the breadth of Cardano-based applications. Furthermore, TyphonJs addresses the difficulty of offering a user-friendly and dependable wallet library, facilitating the integration of Cardano capabilities and lowering entry barriers for new projects.

[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?

We have a proven track record of delivering projects with high levels of trust and accountability, making us well-suited to successfully complete the proposed project. Our team's experience and expertise in the Cardano ecosystem demonstrate our capability to deliver with confidence and without risk. We have a strong reputation for managing funds properly, ensuring transparency and adhering to responsible financial practices throughout the project.

Our previous projects, such as Cardanoscan and Typhon Wallet, showcase our commitment to innovation and providing valuable solutions to the Cardano community. Cardanoscan, a widely used Cardano explorer, has been successfully constructed and maintained by our team. Typhon Wallet, a highly recognized and user-friendly wallet, has received widespread acclaim for its features and usability. Our involvement in the Catalyst program highlights our dedication to driving community solutions and pushing the boundaries of innovation.

In addition, we have successfully delivered the integration of Cardano ADA and native tokens within Ledger Live, bringing the extensive user base of Ledger to Cardano. This integration not only expands the reach of Cardano but also provides a safe and secure custodial wallet solution for the community. These accomplishments demonstrate our ability to handle complex technical integrations and deliver user-centric solutions.

Furthermore, our contributions to the Cardano ecosystem through open-source libraries on our GitHub repository (https://github.com/StricaHQ) reflect our commitment to providing dependable tools and resources for developers. These libraries have been developed with a focus on high-quality standards and transparency, ensuring that developers have access to reliable resources for their projects.

Overall, our experience, knowledge, and favourable feedback from the community establish our capacity to deliver projects with integrity and responsibility. We are confident that our capabilities, coupled with our commitment to the Cardano ecosystem, will enable us to successfully complete the Cardanoscan Maintenance project and continue to contribute to the growth and development of the Cardano community.
