[GENERAL] Summarize your solution to the problem (200-character limit including spaces)

We will open source a TypeScript library enabling projects to autonomously capture and analyze Cardano blockchain data for metadata, asset owners, and asset minters for a wide variety of use cases.

[GENERAL] Does your project have any dependencies on other organizations, technical or otherwise?

No

[GENERAL] If YES, please describe what the dependency is and why you believe it is essential for your project’s delivery. If NO, please write “No dependencies.”

To support unlimited portability, the library will utilize a Cardano API provider, such as BlockFrost, as the source of the raw blockchain data. The library will support any data source with the necessary information and is not dependent on any specific third party. To remove all external dependencies, the data source could also utilize an in-house Cardano node for the more technical projects.

[GENERAL] Will your project’s output/s be fully open source?

Yes

[GENERAL] Please provide here more information on the open source status of your project outputs

Our entire Cardano snapshot solution will be open source and free to use. Our modular, open source design will ensure portability, transparency and community collaboration on all components of the solution ranging from data granularity to wallet analysis and filtration. This will allow our solution to serve as the backbone for a multitude of new, cutting-edge snapshots that can be used to recognize and reward the most loyal and engaged members of project communities.

[SOLUTION] Please describe your proposed solution

While providing a large variety of services on Cardano over the past few years, we have found snapshots to be one of the most critical and common dependencies shared by all services. Whether a project needs to prepare a whitelist, generate an airdrop, set up a staking platform, run minting raffles, support asset-based Discord roles, provide token-gated website, show asset metadata on a website, or provide any other service based on asset metadata or asset holders, snapshots are the foundation. With that said, there are no open-source snapshot tools that are easy to use and robust enough to support all of the use cases described.

Our snapshot solution, a portable TypeScript library that can be utilized in any website or server environment, will have a feature-first design built with project owners in mind. The tool will cover all common use cases out of the box, with the ability to build upon the solution for more advanced situations. This includes, but is not limited to, holder snapshots based on policy IDs, metadata snapshots for policy IDs, snapshots for the original minters of assets based on policy IDs, and stake pool delegator snapshots including the assets held by each wallet.

The snapshots will be efficiently performed by running requests in parallel to the data source. There will be built-in protection for request failures (due to network issues, exceeding allowed request frequency, etc.) that retries the requests at safe intervals. The snapshot will not be disrupted by these issues, but will instead carry on normally as soon as the requests are successful again. There will also be several configurations available for the snapshots, relating to request frequencies, data filtering, and more. When it comes to wallet addresses, there will be advanced detection and filtering of wallet data including era (Byron vs. Shelley), payment part, and delegation part. If the address is a script (smart contract), there will even be the ability to see if the first address with the shared stake key was also a script; in other words, you can see if the wallet was originally created as a normal user payment wallet or if the wallet is only used for scripts. All of this information is essential when it comes to preparing meaningful whitelist and airdrop setups.

Obtaining the data is only one part of the solution. Once we have the data, we need to understand it and make use of it. This tool will come with support for various output granularities (some examples being asset-level, address-level, and wallet-level) to enable usage in every situation. The initial goal is to provide JSON output, however that may be expanded upon based on community feedback.

Demonstrating Impact:

We will track the adoption of our solutions through direct feedback, tool usage metrics, and success stories from project owners who utilize our snapshot solution. This will allow us to continuously refine our offerings and provide tangible evidence of our impact on the ecosystem.

Uniqueness and Benefits:

What sets our solution apart is its proven track record, ease of integration, support for any level of complexity, and robust error handling. By democratizing access to high-quality snapshot tools, we are helping to lay the technical foundation needed for rapid and valuable project growth and accomplishments.

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

Our project will significantly enhance the Cardano ecosystem by democratizing access to snapshot technology, expediting project development, opening the door to new methods of recognizing community members’ loyalty to a project, and reducing dependency on costly service providers. By open-sourcing our advanced airdrop solution, we empower creators across the globe to capture, track, and manage project data independently with a secure, scalable, and free tool. This not only drives innovation within the Cardano community but also attracts new users and developers to the platform, strengthening its position in the competitive blockchain space.

We will measure the impact of our project through several key metrics:

1. Adoption Rate: Tracking the number of projects and users adopting our tool.
2. Community Contributions: Monitoring updates and enhancements made by the community to the open-source code.
3. Innovative applications: Noting success stories from projects on ways they were able to add value to the ecosystem by advancing their snapshot capabilities.

To ensure wide distribution and engagement, our outputs will consist of:

• A GitHub repository hosting the complete source code
• Comprehensive documentation of how to configure and facilitate any type of snapshot using our tool
• Advice, insights, and guides on the best practices surrounding common snapshot use-cases, gained from several years of experience performing them

These efforts will not only showcase the practical benefits of our solution but also reinforce Cardano's reputation as an inclusive and innovative blockchain community.
