[IMPACT]
Development of a community cross-browser light wallet with a popup format that supports switching networks and unifying all of them within the same tool from the same account, in addition, being able to choose your own trusted endpoints.
The light wallet type, the user-friendly 'popup' format, and the quick installation will make it easy for users to adopt the wallet.
The capacity to easily add new use cases/plugins and the ability to customize endpoints will attract more experienced users.
The testnet support and dapps connector integration will appeal for developers. Improving the user experience, gains versatility and, besides being able to mine NFTs, we can add new capabilities by adapting to the advances and new functionalities brought by the Alonzo era and future ones.

[FEASIBILITY]
The extension wallet is the MVP and core of the project, we want to offer an intuitive extension wallet experience to interact all capabilities in the Cardano ecosystem.
Initially, we will analyze and explore existing tools and libraries, then choose the ones that best suit our needs, for the wallet side.
The wallet development will be led by a full stack developer, who will provide public progress reports.
This developer will be in charge of implementing frontend views, crypto libraries, types, data persistence, language management, among others, see bellow tentative timeline.
By achieving the proposed objectives, we will be able to offer a light wallet with full capabilities to everyone as browser extension.
- Create/restore accounts.
- Send payments, use metadata.
- Hold assets, native tokens, NFTs.
- Mint NFTs, native tokens.
- Get rewards while staking.

<u>About C64:</u>
The C64 project started in April 2021 with a fund5 proposal[0] for a purpose-built desktop wallet to mint signed NFTs, stored 100% on the blockchain. Allowing anyone to create, verify and link identities to digital assets, such as works of art with the artists.

Tracking of project progress and KPIs will be publicly reported every two weeks to Catalyst organizers and the rest of the community through our social media channels.
Video demos will be publicly shared to show KPIs achievements.
The proposal is considered completed when all KPIs have been satisfactorily completed, before the time frame of 6 months and the wallet is available for download in the detailed web browsers.
The development started as a cross-desktop wallet[0], with the imminent arrival of smart contracts the project evolved towards the creation of a wallet to be used from the browser to facilitate interaction with websites.
In this way, the wallet improves the user experience, gains versatility and, besides being able to mine NFTs, we can add new capabilities by adapting to the advances and new functionalities brought by the Alonzo era and future ones.
<u>From Minter to Modular Wallet</u>
Thus, we decided to go a step further and expand the vision and capabilities of the wallet, adapting the initial proposal[1] to a modular wallet, where, starting from a basic wallet functionality with a friendly extension user experience, we will establish new functionalities such as support for switching between different networks, the possibility of choosing your trusted endpoints, and being able to add specific use cases in the form of addons, being the 'C64 Minter' the first to be included.
