[Proposal Summary] Problem Statement

What is the problem you want to solve?

Developers need smart contracts and integrated UI templates designed for scalability and modularity, supported by a framework. These templates will showcase practical, real-world Midnight applications

Mention your open source license and describe your open source license rationale.

All code and templates produced in this project will be released under the MIT License. This permissive license encourages broad adoption and reuse, supports both open-source and commercial use, and aligns with our goal of lowering barriers for developers by allowing contributions, forks, and integrations without legal or operational friction.

How do you make sure your source code is accessible to the public from project start, and people are informed?

We use GitHub to host our repositories from the project start. All development is tracked in public GitHub projects, allowing stakeholders and contributors to monitor progress and access code at all times.

How will you provide high quality documentation?

We will provide a README.md file for each contract and UI module to guide installation and usage. A well-structured documentation site will include tutorials, how-to guides, and educational content to help developers follow and build upon each part of the framework easily.

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

We will create four modular smart contracts with integrated UI, API, and testing:

• Tokenization: Minting, burning, and fractionalizing assets
• Staking: Delegation mechanics and rewards distribution
• Identity: DID flows and provider integration
• Oracles: Secure on-chain data feed consumption

Each will serve as a real application example and be delivered as reusable templates within a framework built to promote interoperability and collaboration. Developers will be able to build on top of these contracts or integrate them with others, fostering a composable ecosystem of privacy-enabled applications on Midnight.

The proposed framework will be structured to streamline the full development lifecycle of Midnight smart contracts. It will consist of three main folders:

• Contracts Folder
  1. Contains smart contract logic and witness code
  2. Logical test framework for smart contracts
  3. Reusable templates for common patterns
• API Folder
  1. Manages instances, providers, and CLI application logic
  2. TUI interface
  3. Test framework that interacts with providers and Midnight blockchain network (standalone and testnet)
• Frontend Folder
  1. APIs for each contract
  2. React glue code for each contract (providers and hooks)
  3. Ready-to-use React components for UI integration

[Your Project and Solution] Impact

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

• Brings immediate value to the Cardano community by making it easier for developers to build privacy-preserving apps with Midnight.
• Lowers the barrier for entry through reusable, modular contract and UI templates.
• Promotes interoperability by allowing integration with existing and future contracts.
• Supports real business use cases: tokenization, staking, identity, and oracles.
• Integrates with MeshJS tooling to align with current Cardano development workflows.
• Encourages collaboration and reuse across the ecosystem.
• Measured through GitHub activity, adoption by developers, and engagement from the community.

[Your Project and Solution] Capabilities & 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?

1. We have participated in more than four Midnight hackathons, earning 1st and 2nd place awards, receiving outstanding feedback from the Midnight engineering and developer relations teams.
2. Our open-source code is part of the official Awesome Midnight repositories.
3. We produce ongoing educational content for developers via Discord, further validating our outreach and technical clarity.
4. We manage development using GitHub Projects and issues, ensuring public accountability, milestone tracking, and responsible fund management.
5. MeshJS has a proven track record of providing developer tooling to the Cardano ecosystem. We have already developed the Mesh Midnight SDK and a fully working Starter Template, including:
   • A smart contract already compiled and tested
   • APIs
   • A reusable UI framework using React
   • A fully operational testing layer
   • A wallet widget

This proposal builds directly on top of this starter template and tooling, making the effort low-risk and highly feasible.

[Final Pitch] Budget & Costs

Please provide a cost breakdown of the proposed work and resources

1. Development – Smart Contracts & Full-Stack (80% = 52,000 ADA)

• Scope: Design, implement, and test four modular smart contracts (Tokenization, Staking, Identity, Oracles) with integrated UI, API, and testing frameworks.
• **Resources: **Smart contract engineer and Full-stack developer.

1. Project Management (10% = 6,500 ADA)

• Scope: Coordination of milestones, resource planning, task tracking, reporting to the community, and ensuring timely delivery.
• Resources: Project manager for milestone tracking and use of GitHub Projects for transparent progress tracking

1. Treasury Management (10% = 6,500 ADA)

• Scope: Fund management, accounting, and financial oversight; maintaining a buffer for ADA price fluctuations during the 10-month delivery period.
• Resources: Treasury oversight team and Accounting support.

Shortfall Coverage:

In the event of additional costs, the MeshJS team will leverage internal resources to absorb the gap without compromising deliverables.

[Final Pitch] Value for Money

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

This 65,000 ADA budget covers 10 months of work by a specialized team delivering four production-ready smart contracts with integrated UI, APIs, and testing frameworks. Costs are proportional to standard blockchain developer and project management rates, ensuring fair compensation while maximizing productivity. Building on the existing Mesh Midnight SDK and Starter Template reduces development risk and accelerates delivery. The resulting open-source, reusable, and interoperable templates will lower the barrier for new developers entering the Cardano and Midnight ecosystems, enabling faster integration of privacy features and fostering the creation of real-world applications.
