Developer Tools
Describe what makes your idea innovative compared to what has been previously launched in the market (whether by you or others).
Astrvo Engine introduces a level of accessibility, modularity, and blockchain-native integration that does not currently exist within the Cardano ecosystem. Its innovation comes from combining Unity, CIP-30 wallet integration, multiplayer networking, avatar system, decentralized storage, and reusable 3D prefabs into a single developer-friendly toolkit.
Why Cardano?
Cardano provides deterministic eUTxO execution, the CIP-30 wallet standard, a native asset model, and verifiable NFT metadata. These composable capabilities enable 3D dApps to securely bind user identity, assets, and interaction events. Unity alone cannot provide verifiable ownership, while other blockchains either lack universal wallet standards or incur excessive fees. Therefore, Astrvo Engine must be built on Cardano.
Core innovation factors:
1. First Modular 3D DApp Creation Kit for Cardano:
While other chains offer metaverse experiences or individual game projects, no blockchain currently provides a standardized, open-source Unity SDK that lets developers assemble 3D DApps like building blocks.
Astrvo Engine’s modular wallet, identity, and multiplayer components drastically reduce complexity and lower the entry barrier for Web2 and Web3 developers alike.
2. One-Click Integration of Cardano Wallet, Identity, and On-Chain Logic:
Typical Web3 3D development requires manual integration of CIP-30, custom authentication, NFT metadata parsing, and token logic.
Astrvo Engine offers:
3. Real-Time Multiplayer + Web3 Wallet Support in a Single SDK:
Multiplayer 3D sync on its own is complex; integrating that with wallet-based identity and blockchain logic is even harder.
Astrvo Engine provides the first Cardano-ready multiplayer 3D engine designed for SocialFi, GameFi, community spaces, exhibitions, and virtual events. Including:
4. Simplifies 3D DApp Development from Months to Days:
Without Astrvo Engine, teams must understand:
Astrvo Engine pre-packages all these into reusable components, and 3D DApps become feasible for small teams, not only large studios.
5. Open-Source Standard Infrastructure for Cardano 3D Applications:
The project is fully open-source under MIT/Apache, enabling Forks, Extensions, Integrations, Community-driven standards.
This positions Astrvo Engine as the first shared foundation for Cardano 3D DApps, similar to what Hardhat did for smart contracts or Unity’s XR Toolkit did for VR. This could be a foundational layer that can become the “default way” to build 3D DApps on Cardano.
6.Designed for Future Expansion: Editors, AI Tools, and Decentralization:
The long-term roadmap includes:
These future capabilities transform Astrvo Engine from a developer toolkit into a full 3D decentralized application platform.
Describe what your prototype or MVP will demonstrate, and where it can be accessed.
This proposal delivers Astrvo Engine SDK v0.1: an open-source toolkit including the core engine, an online space demo, and full documentation.
As an MVP, it will act as foundational infrastructure for SocialFi and GameFi applications, validating the value of “lowering the barrier to 3D DApp development” and injecting new creative energy into the Cardano ecosystem.
Core Features of Astrvo Engine SDK v0.1:
1. Core Engine & Architecture:
A highly modular Unity project structure with clean separation of logic, UI, and networking layers.
2. Prefab-Based SDK Components:
3. Example Project & Documentation:
Describe realistic measures of success, ideally with on-chain metrics.
The success of Astrvo Engine SDK v0.1 can be evaluated through concrete, measurable, and realistic indicators across technology adoption, developer engagement, and on-chain usage.

2. Developer Adoption Metrics:
These ecosystem-level metrics represent early traction:
3. On-Chain Success Metrics:
Astrvo Engine includes CIP-30 wallet login and NFT/Token reading; on-chain measurable activity can be tracked:
4. Community & Education Metrics:
These metrics evaluate user engagement and impact:
Rationale Summary:
These metrics collectively evaluate:
All metrics are realistic because they align directly with the project scope, community size, and the expected traction of a foundational SDK in the Cardano ecosystem.
Please describe your proposed solution and how it addresses the problem
Astrvo Engine reduces the barrier of creating 3D DApps on Cardano by providing a fully open-source, modular Unity SDK that includes all the essential modules needed for Web3 3D applications.

Please provide a cost breakdown of the proposed work and resources
Requested funding: ₳100,000
How does the cost of the project represent value for the Cardano ecosystem?
Astrvo Engine delivers strong value for the Cardano ecosystem by producing open-source infrastructure that can be reused indefinitely by developers, projects, and communities. Instead of funding a single application, this proposal funds a foundational 3D development toolkit that lowers costs for dozens of future Cardano projects. The requested budget (₳100,000) directly supports engineering work, documentation, multiplayer network development, and community onboarding, areas that require specialized expertise but produce long-term ecosystem benefits.
1. High Leverage: One SDK to Many Future Projects
Without the Astrvo Engine, teams must individually build wallet integration, multiplayer systems, character controllers, UI frameworks, on-chain identity, and decentralized storage logic.
This typically costs $80K–$200K per project in Web3 gaming and metaverse development.
Astrvo Engine eliminates that duplication by providing:
Astrvo Engine centralizes all of this into a single MIT-licensed SDK, reducing:
If 10 projects use the SDK, Cardano gains $1M–$2M in saved development cost.
2. A True Infrastructure Investment
Astrvo Engine establishes reusable standards for:
We estimate the SDK can support at least:
This positions Cardano as one of the few chains with a ready-to-use 3D development stack.
3. Open-Source Licensing Maximizes Community Benefit
All SDK code, examples, documentation, and tools will be released under MIT/Apache, enabling:
The community gets permanent access to all deliverables at no ongoing cost.
4. Expert Engineering at a Reasonable Budget
The budget is allocated responsibly:
Building a full 3D engine with wallet login, NFT logic, decentralized storage integration, multiplayer sync, and backend management would cost far more in traditional industry settings. This proposal offers enterprise-level development at a fraction of the typical market cost.
5. Long-Term Ecosystem Growth and Developer Expansion
By enabling any Unity or Web2 developer to build on Cardano in days instead of months, the SDK:
By lowering technical barriers, Astrvo Engine aims to produce measurable adoption:
Each new project built using the Astrvo Engine multiplies the impact of the original funding.
6. Measurable ROI with Transparency
The project provides measurable, verifiable outputs:
These ensure Catalyst funds are used effectively with clear, measurable outcomes.
Future Plan:
Future 1: More Modules & Advanced Features
Future 2: Visual Space Editor
Future 3: Decentralized Networking Integration
In summary:
Astrvo Engine provides exceptional value for money by producing open-source, reusable 3D infrastructure that empowers the entire Cardano ecosystem. The cost of development is small compared to the long-term benefits of enabling many future SocialFi, GameFi, virtual event, and immersive community projects. The SDK significantly lowers development cost, accelerates innovation, and strengthens Cardano’s position in the Web3 3D landscape at a highly efficient budget. With 20-40 projects expected to adopt Astrvo Engine, total ecosystem savings reach $3M–$6M in avoided duplicated development cost.
