[IMPACT]

The goal of the project is to create two open-source NFT swapping smart contract templates and matching off-chain code and front-end templates.

One for swapping of specific tokens that can be individually listed, with the option to accept or reject swap offers.

One for random swapping from a community pool.

When a swap would be initiated by a user sending a tx with an NFT to the smart contract address, the contract would randomly return a different NFT from those available in the pool to the sender. Depending on the needs and make-up of the project, multiple SC and associated pools could be deployed, for instance, each one corresponding to a specific rarity level.

The contents of the community swapping pool could either be visible to the users or not, depending on the preference and the needs of each project.

The smart contracts will also allow the creators of the project to charge a small fee on each swap, to ensure the sustainability of their swapping service (development, hosting, etc.).

To achieve our goals of creating easy-to-implement open source templates, in addition to the development of the code and the UI templates, we also plan on writing clear and extensive documentation for everything we release.

Besides the immediately visible benefits in providing the Cardano NFT creators community with templates that are easily adaptable to their own projects, the main motivator for us, and what got us working on the swap pools idea in the first place, are the benefits that the NFT space as a whole would get from the encouragement of the idea of swapping.

These include:

• The fun resulting from engaging with the swap pools (particularly the random one)
• Discovering or rediscovering the joy of collecting
• An easier way to complete collections
• A better appreciation of collections by getting to spend more time with them when looking for NFTs to swap
• Social interactions that can occur between collectors while looking for NFTs to swap
• Offering long term value to collections, beyond the initial hype
• And many more

All of these are meant to grow the collectibles NFT ecosystem beyond its main current drivers: profits and social status.

Most importantly, however, we hope that our efforts will bring about a new way of looking at collectible NFTs. One that will combine all the new value propositions that NFTs and the technology behind them offer, with the value layer that traditional collectibles such as Pokemon cards, basketball cards, stamps, coins etc. bring. All of these rely heavily on the experience of swapping between members of their respective communities, either as a means of completing collections or simply for the joy of collecting.

We see Cardano as a natural fit for this type of experience, as this can only happen on a blockchain with small fees and fast transactions. On top of that, through the power of eUTxO, swaps can be done in a single transaction.

We hope that from everything we have described above you will see the value that our project can bring, and the impact it would have on the Cardano NFT space and the Cardano environment as a whole. After all, the Cardano community prides itself in being motivated by factors other than quick profits and short-term hype.

Besides the factors mentioned in the first part of our proposal, our project addresses multiple key questions posed by the challenge:

How can we ensure future efforts benefit from the work that is funded today?

By creating and making the smart contract, backend, and frontend templates available to the Cardano NFT creators community, any project that wishes to implement the swapping service in the future for their specific communities will be able to do so much more easily, significantly faster, and at a much lower cost compared to having to develop their own solutions from scratch.

How can we encourage experts to collaborate and share their knowledge and work?

We will be looking to collaborate with established developers in the Cardano community. By getting them to work on this open-sourced project, we will ensure that the knowledge they have accumulated is recorded and made freely available for all to draw upon and potentially improve.

In time, as projects start to implement the swap pools feature, we foresee the codebase growing with more and more developers contributing, motivated by wanting to adapt it to their own specific needs.

How can we develop a sustainable ecosystem while sharing knowledge and efforts?

By creating the swap pool templates, projects that wish to implement the feature would have much smaller up-front development costs.

Funding the project would contribute to getting developers to work on open-source Cardano-specific code, while being compensated fairly to do so.

Projects implementing one or more swap pools could greatly increase their longevity by keeping the community engaged and motivated to collect, thus increasing their long-term sustainability.

Projects could implement a small royalty on swaps (possibly smaller than the one on marketplaces, or a fixed fee) that would further contribute to their sustainability.

The biggest challenge that we foresee is a lack of qualified and available Haskell/Plutus developers.

We see this risk as being mitigated by two factors:

1. We have adequately budgeted for the smart contract developer position to make it more attractive. This is especially important to consider as the number of ventures launching on Cardano increases every day, we have seen a lot of Catalyst projects not taking this into account and not properly budgeting as a result.
2. Our contacts and connections within the Cardano ecosystem.

[FEASIBILITY]

We plan to structure the development of the project into two stages, each taking approximately 3 months to complete. As such we have taken the decision of also breaking up the scope of the project into two separate proposals. We are submitting the first for consideration in this fund. If approved and funded, we will be submitting the second in Fund 9.

In the following sections, we will describe the scope of the entire project and end with a clear description of what will be included in each phase. For simplicity, we will be dividing the budget into 2 equal parts.

Implementation plan:

1. Assemble a team of developers (smart-contract, backend, frontend); designers (UX & UI); market research and project management.
2. Perform detailed market research to better understand the needs of projects.
3. Together with the development team design the swapping Smart Contract blueprint, diagrams, and preliminary UX.
4. Write a first version of the specific token swapping contract.
5. Implement a randomizer engine in the smart contract code using outside data (potential sources of randomness we are looking at include oracles and exchange prices)
6. Write a first version of the random swap contract
7. Design the detailed version of the swapping UX
8. Design at least two versions of UI templates
9. Write the off-chain code needed for the backend
10. Build the frontend component of the service
11. Write extensive documentation for each component of the service
12. Create marketing materials
13. Promote the swap pools as open-source resources and get the Cardano NFT community interested in the idea
14. Launch the first version of the swap pools

Estimated Launch Date

We expect we would need 5-6 months of development time from the start of the project, so we expect a Q4 2022/ Q1 2023 launch date.

We are the creators of the Trybbles collectible NFT project on Cardano (<https://www.trybbles.com>) and we plan to use this to our advantage in the development of the swap pools initiative.

We have recently launched a manual version of the Swap Pool for the Trybbles community. The 0.5 version of the Swap Pool is a manual service, meant to set the stage for a potential automated smart contract-based solution in the future. We started off by using <https://atomic-swap.io> for the service.

More details about the initiative can be found in the announcement post ( <https://twitter.com/trybbles/status/1495117792651390976> ) or by joining the project’s Discord server ( <https://discord.gg/AwEnRpRdcV> ).

But we want to take things much further, and rather than creating a proprietary solution we aim to create a suite of open source tools and templates implementable with ease by any Cardano NFT project that wishes to do so.

[AUDITABILITY]

Each deliverable, as detailed above in the implementation plan, will be recorded and submitted via the Catalyst Monthly Reporting form.

Monitoring development of the project deliverables will also be possible on the project’s GitHub.

In addition to recording the deliverables we will measure the success of the project by monitoring and reporting on the following KPIs:

• Number of open source GitHub commits.
• Number of bugs identified in the testing phase.
• Achieve a high level of understandability in the code documentation.
• Number of interactions with the project’s repositories by outside developers.
• Numbers of projects that implement the project in the first month after launch

Success after 3 months:

The team needed to successfully complete the project is assembled and work is underway.

Phase 1 is completed.

Success after 6 months:

The project’s open-source deliverables, as described above, are executed according to the timeline, without a deviation of more than 20%.

Phase 2 is completed.

The project is successfully launched.

Success after 12 months:

Between 3-6 different Cardano NFT projects have implemented their own version of the Swap Pools successfully.

Because they can make use of a robust set of tools and templates easily adaptable to the needs of their projects, other developers are motivated to join the wider Cardano open source community and contribute.

As a result of the project, new connections are formed between members of the Cardano open source community, potentially leading to further fruitful collaboration.

This is an entirely new proposal.
