Please describe your proposed solution.

Stateful NFTs can be really complex. For example, the image for your NFT could be the result of a complex aggregation of multiple events on chain and heavy computation. This means that building a NFT marketplace that renders all Stateful NFTs perfectly is a hard problem

Instead, our goal will be to create a system so that games and apps can easily and cheaply setup app-specific NFT marketplaces that render their NFTs as desired. To avoid this having a negative impact on the liquidity of the NFT, we will build it in such a way that using this system means your NFT can still appear on other NFT marketplace (albeit maybe without being able to render the information in the NFT in as rich of a way)

We also want to build a browser extension that helps render Stateful NFT information on existing marketplaces so that users can still get the full stateful information without having to resort to hunt down a lot of app-specific marketplaces

How does your proposed solution address the challenge and what benefits will this bring to the Cardano ecosystem?

The benefit is that projects using Stateful NFTs to power their app or game will have better access to liquidity, making their project have a high chance to gain traction and become a successful project in the Cardano ecosystem – all while still having the flexibility to build a comprehensive personalized experience for their collection

How do you intend to measure the success of your project?

• Volume of Stateful NFTs on general NFT Marketplaces that were made possible by this infrastructure
• Number of projects that launch an app-specific marketplace
• Number of downloads for the chrome extension

Please describe your plans to share the outputs and results of your project?

We will release all the code for the cross-market listing system, documentation on how to build your own marketplace as well as the chrome extension

What is your capability to deliver your project with high levels of trust and accountability?

dcSpark and Paima Studios are well renowned companies in the Cardano ecosystem that have a long history of delivering on Catalyst proposals. You can find progress on grants we have previously received at https://dcspark.io/grants

What are the main goals for the project and how will you validate if your approach is feasible?

The main goal is to increase the liquidity for Stateful NFTs which will make gaming and gamification use-cases on Cardano much more appealing

We know this project is technically feasible because Seaport is a library that achieves something similar, although without being fine-tuned for Paima

Please provide a detailed breakdown of your project’s milestones and each of the main tasks or activities to reach the milestone plus the expected timeline for the delivery.

1. Build the library for cross-marketplace listing
2. Build the base UI projects can use to build their app-specific marketplace
3. Build the Chrome extension for rendering stateful NFTs

Please describe the deliverables, outputs and intended outcomes of each milestone.

1. Code
2. Code
3. Code

Please provide a detailed budget breakdown of the proposed work and resources.

1. 50k
2. 50k
3. 40k

Who is in the project team and what are their roles?

• dcSpark (development support)
• Paima Studios (advising on the use-case)

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

This will allow projects using Stateful NFTs in the Cardano ecosystem to a better chance at being successful, increasing the number of successful games and NFT projects in the Cardano ecosystem
