Please describe your proposed solution

We will follow the steps below to implement our solution:

1. Ecosystem Analysis and Interviews: Analyze the Cardano validator ecosystem and conduct interviews with select operators to understand their monitoring, reporting and observability requirements.
2. Infrastructure Extension: Extend our infrastructure to include Cardano mainnet and Preview testnet validators, and RPC archive nodes, integrating them into SubVT.
3. Proof-of-Stake and Storage Analysis: Perform a deep analysis of the Cardano proof-of-stake system and storage, and prepare an execution plan for its integration into the SubVT backend.
4. Backend Implementation: Implement the backend extensions into our existing backend.
5. Mobile App Integration: Implement iOS and Android application extensions.

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

SubVT aims to enhance the security of Cardano by offering improved tooling for the validator operators. Additionally, it will contribute to the overall user experience through its well-designed UI and UX.

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?

Our proven track record in the Polkadot ecosystem over the past four years demonstrates our capability, trust, and accountability. We have successfully delivered two Web3 Foundation grants and one Kusama treasury grant. Additionally, we are part of the Infrastructure Builders Program (IBP), providing RPC services to nearly 30 blockchain networks. We operate validators under both Kusama and Polkadot Thousand Validators programs. Most recently, our Submerge project proposal successfully passed the community vote, further validating our commitment.

What are the key milestones you need to achieve in order to complete your project successfully?

Backend Implementation

2 months, 1 FTE = $33,120.00

iOS App Development

3 months, 1 FTE = $49,680.00

Android App Development

3 months, 1 FTE = $49,680.00

TOTAL: $165,600.00

No dependencies.

How does the cost of the project represent value for money for the Cardano ecosystem?

SubVT offers strong value for money, under a modest budget, by leveraging our existing infrastructure, backend and application code base, already proven in the Polkadot ecosystem. We aim to contribute to the overall stability and security of the network by providing improved observability for validator operators. Our solution is fully open-source, ensuring both long-term sustainability and community-driven development.
