Metaverse

[Campaign Category] Category Questions

Describe what makes your idea innovative compared to what has been previously launched in the market (whether by you or others).

Astrvo is innovative in four key ways:

• Cardano-native design for real communities:

Unlike generic metaverse platforms, Astrvo is built specifically for Cardano projects. Our first use case, the Snek Den Taiwan virtual meetup, will shows how Cardano communities can host branded, interactive 3D events directly tied to their tokens, NFTs, and culture.

• Lightweight and accessible in the browser:

Astrvo requires no downloads or VR devices. It runs through WebGL on any browser, with optimization for mobile users. This makes immersive 3D experiences accessible to a much wider audience in the Cardano ecosystem.

• Real-time interaction combined with on-chain actions:

Users can log in with CIP-30 wallets, interact in real time, and display or use their on-chain assets (e.g., NFTs, identity badges). This bridges social presence with blockchain utility in a way not previously available on Cardano.

• Innovative activity formats:

Enable project teams and DAOs to host new forms of events such as virtual AMAs, open spaces, 3D NFT exhibitions, interactive workshops, and GameFi/DeFi-based on-chain activities.

Describe what your prototype or MVP will demonstrate, and where it can be accessed.

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

Astrvo provides a lightweight Web 3D space platform, where Cardano users can build virtual space, meet, interact, and use their on-chain identity. Users log in through the CIP-30 wallet or Google with wallet binding, allowing their address and CNT/NFTs to load directly into the environment.

The 3D hub supports real-time multiplayer interaction and integrates key on-chain actions, including NFT display, token-gated access, and future extensions for GameFi/SocialFi mechanics or merging with Defi smart-contract interactions.

Astrvo is built as a scalable platform infrastructure. Once the MVP is delivered, the same architecture can rapidly deploy dozens of customized 3D spaces for Cardano communities, SPOs, projects, and events, supporting branded experiences, education, social interaction, and gaming.

The MVP is validated through a fully deployed virtual event for the Snek DEN Taiwan, where wallet login, multiplayer sync, NFT rendering, and user engagement metrics demonstrate the feasibility and demand for a 3D social layer in the Cardano ecosystem.

[Your Project and Solution] Impact

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

Astrvo will bring a measurable and meaningful positive impact to the wider Cardano community by creating a new, immersive way for users to connect, participate, and express their on-chain identity.

• Strengthening community engagement across Cardano

By providing a 3D virtual hub accessible directly from the browser, Astrvo allows communities to host immersive meetups, events, and exhibitions that go far beyond the limitations of Discord or Telegram.

Our first deployment—the Snek Den Taiwan Virtual Space—serves as a model for how Cardano-native communities can host branded, interactive events that increase participation and belonging.

• Increasing user activity and retention

With wallet login, NFT visualization, and real-time multiplayer interaction, users spend more time engaging with Cardano projects.

Our targets include:

1,000+ visits for the first community event

10+ minutes average stay time

High wallet connection success (98%)

These metrics demonstrate that immersive experiences can meaningfully increase community touchpoints.

• Expanding the ecosystem through collaboration

Astrvo is designed to be reusable for other Cardano projects, DAOs, NFT communities, and DeFi/GameFi teams.

After the Snek Den deployment, we will collaborate with additional projects to build dedicated spaces for their events, launches, and onboarding sessions—growing Astrvo into a network of interconnected Cardano virtual hubs.

• Enabling new forms of on-chain interaction

By merging real-time 3D environments with wallet connectivity, projects gain new ways to: host NFT-gated events, showcase collections in 3D, run interactive workshops, integrate DeFi/GameFi actions directly into the environment. This expands what is possible for Cardano creators and developers.

[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?

Our team has a strong track record of delivering high-quality immersive environments in Web2, giving us the technical foundation and production experience to deliver Astrvo reliably.

[Final Pitch] Value for Money

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

The requested budget of 60,000 ADA represents strong value for the Cardano ecosystem because the project delivers reusable infrastructure, a real community deployment, and long-term ecosystem impact far beyond the cost.

1. High output for a relatively low cost

For 60,000 ADA, the project delivers:

• A full 3D virtual community hub accessible from any browser
• Multiplayer networking, avatar systems, wallet login, and NFT integration
• A real-world deployment for the Snek Den Taiwan community
• A complete activity and analytics report
• A reusable template that future Cardano projects can use at no additional cost
• Considering that similar Web2/Web3 3D platforms cost 10–50× more to build, the budget is efficient and highly competitive.

2.Reusable open-source SDK reduces future costs for the ecosystem

Key components—wallet integration, smart contract modules, and avatar systems—will be released under the MIT license, allowing any Cardano developer to reuse them freely.

This means the ecosystem receives infrastructure that would normally cost tens of thousands of dollars to recreate.

• Future Cardano projects will be able to:
• Launch their own 3D community spaces quickly
• Reuse wallet and NFT modules without reinventing them
• Build GameFi, SocialFi, and DAO tools on top of Astrvo’s open-source base
• This compounds long-term value at no extra cost to the treasury.

3. Direct impact on Cardano community engagement

The first real use case—Snek Den Taiwan Virtual Meetup—will generate measurable engagement:

• 1,000 visits
• Message-signing interactions: ≥ 500 signed data proofs
• Unique wallet connections: > 1,000
• NFT metadata read count: > 5,000 successful reads
• 10 minutes average session time
• 98%+ wallet login success

These metrics demonstrate high ROI in terms of community activation and visibility.

Success in this event becomes a repeatable model for other Cardano communities, increasing adoption organically.

4. Low operational overhead through lightweight WebGL architecture

Astrvo runs directly in the browser through WebGL and is optimized for mobile devices.

This avoids:

• Expensive native app development
• High server and hosting costs
• Complex VR hardware requirements

The result is maximum reach at minimum cost, ensuring high cost–effectiveness.

5. Long-term ecosystem growth through collaboration

After the Snek Den deployment, Astrvo can be adopted by:

• Other Cardano NFT communities
• DeFi/GameFi projects
• DAOs and governance groups
• Educational or onboarding initiatives

The same core infrastructure can host dozens of future events without requiring new treasury funding.

This makes the initial 60,000 ADA investment multiply in value over time and become a high-engagement experience that strengthens Cardano’s social layer

This represents excellent value for money, benefiting not only one project but the entire Cardano ecosystem.
