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.

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.
