[GENERAL] Please indicate if your proposal has been auto-translated into English from another language

No

[GENERAL] Summarize your solution to the problem (200-character limit including spaces)

We will integrate Cardano’s Conway governance features into Ledger Live, enabling users to delegate voting power and support updated stake certificates, enhancing their participation in governance.

[GENERAL] Does your project have any dependencies on other organizations, technical or otherwise?

Yes

[GENERAL] If YES, please describe what the dependency is and why you believe it is essential for your project’s delivery. If NO, please write “No dependencies.”

There is logically no dependency, it is good to know that this proposal is for the ledger live wallet integration, and hence the proposal relies on the company Ledger to be in existence and the wallet to be in existence.

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

Yes

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

Our project will be fully open-source, as Ledger Live itself is an existing open-source product. We will contribute by making pull requests (PRs) to Ledger Live’s official repository.

Ledger Live operates under the MIT License, and we will maintain consistency by using the same licensing for all of our contributions.

[SOLUTION] Please describe your proposed solution

Our proposal aims to integrate Conway governance functionalities into the desktop and mobile versions of Ledger Live. Currently, users of Ledger Live are unable to fully participate in Cardano's decentralized governance, limiting the potential of this unique blockchain feature. It is also mandatory to delegate vote in order to spend staking rewards, hence this upgrade is a critical need before the next hard fork.

The Chang hard fork introduced governance features that are crucial for Cardano users to actively engage in decision-making processes. However, without these features in Ledger Live, a significant portion of users cannot leverage them.

We will implement key governance features including:

1. Delegating Voting Power to DReps: Enabling users to delegate voting power to DReps within Ledger Live. Including default Abstain and No Confidence vote.
2. Support for Updated Stake Delegation Certificates: Adapting the staking functionality to include the new stake registration certificates introduced with the Conway era. Must to cross the next hard fork.

We will engage Ledger Live’s large user base, Cardano DReps, and stakeholders interested in governance. Our solution will directly benefit users who want to participate in decentralized governance but currently cannot do so via Ledger Live.

By enabling participation in governance, we enhance both Cardano's ecosystem and the utility of Ledger Live.

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

Our project will significantly enhance the Cardano community's engagement in governance by integrating essential features into Ledger Live. By enabling users to delegate their voting power, automate voting processes, and support the new stake delegation certificates, we will empower a broader segment of the community to participate in governance decisions effectively. This empowerment is crucial as it fosters a more informed and engaged user base, ultimately strengthening the decentralised governance model Cardano is promoting.

We will share the outputs by contributing open-source code via pull requests to Ledger Live’s official repository.

[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 successfully completing projects while maintaining high levels of trust and accountability. Since the beginning of the Shelley period, our team has been actively participating in the Cardano ecosystem, and we have successfully developed and maintained Cardanoscan, a widely used Cardano explorer.

In addition to Cardanoscan, we created Typhon Wallet, a highly recognised and user-friendly wallet that has received widespread acclaim from the Cardano community. This wallet is a direct result of our involvement in the Catalyst programme, which demonstrates our dedication to innovation and providing important community solutions.

We have also worked and delivered the Cardano ADA, Native tokens, and ADA Staking integration within Ledger Live bringing the mass userbase of Ledger to Cardano and providing a safe and secure custodial wallet solution to the community.

Furthermore, we have contributed to the Cardano ecosystem through a number of open-source libraries, which can be found on our GitHub repository (https://github.com/StricaHQ). These libraries represent our commitment to providing developers with dependable tools and resources that conform to high-quality and transparent requirements.

Our experience, knowledge, and positive feedback from the community attest to our ability to deliver projects with a strong emphasis on integrity and responsibility. We intend to uphold these values throughout the course of our implementation.
