[SOLUTION] Please describe your proposed solution

At Yepple, we’ve observed that many project owners in the Cardano ecosystem are eager to distribute rewards to their community but struggle to use the limited resources available to successfully do so. Often, they resort to seeking our help because managing airdrops independently proves too costly, complex, and error-prone. Mistakes are irreversible on the blockchain, so sending the correct quantities of the correct assets to the correct wallets is absolutely critical. While there are a few private development companies (such as ourselves) that can perform these services, the costs for these services take away project funds and therefore reduce the amount of rewards that the community is able to receive. On top of that, using external development companies adds cost and complexity when attempting to integrate these distributions into a project’s own website/application.

Our open-source airdrop solution tackles this problem by enabling developers and project founders to perform airdrops on their own and entirely remove the cost of service providers. By providing an out-of-the-box API & SDK airdrops, project founders can not only perform the airdrops without any assistance – maximizing the funds they have available for the community rewards – but they can also integrate the process in countless ways within their own websites/applications in a fully automated fashion. The full-stack solution will be built as a Fastify API (written in TypeScript) containing the core airdrop operations with a TypeScript SDK (available on NPM) for interfacing with the API from anywhere.

The solution will be robust enough to handle any and all native assets on Cardano, including ADA, NFTs, and fungible tokens (CNTs). It will also provide intuitive support for tokens following any CIPs, including CIP-68 token prefix support. Reliable error handling will prevent improper token distributions with clear and concise feedback for the user of the tool to fix whatever the issue may be. With a test mode that performs intense validation and provides analytics breakdowns, a “dry run” that mimics a true distribution factoring in available UTxOs, and production mode that performs the actual distribution, there will be no shortage of safety and data available prior to the tokens being distributed.

Intelligent UTxO selection will also enable instantaneous distributions to thousands of wallets by taking advantage of parallel transactions, which is perfectly suited for DeFi token distributions after a presale.

The airdrop transactions will be built with cost-optimization in mind, taking advantage of the UTxO model, utilizing transaction size calculations and other fee optimization strategies to reduce the total number of transactions and blockchain fees associated with each transaction. As mentioned, there will be several modes available allowing for analytics on the transactions that are built. These analytics include fee reporting with a breakdown for different types of fees (such as transaction fees and minimum UTxO fees) and enumeration of all required input assets per transaction, as well as similar aggregate data for the full distribution.

Customization will also be available where appropriate for transaction building, such as CIP-20 transaction messages.

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 airdrop API & SDK. 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 airdrop tools, we are providing a direct injection of empowerment, independence, and wealth into projects and into the wallets of their community members.

[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 airdrop technology, reducing dependency on costly service providers, enabling innovative value sharing mechanisms through an integrated SDK, and promoting a culture of transparency and collaboration. By open-sourcing our advanced airdrop solution, we empower creators across the globe to distribute assets 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. Cost Savings: Calculating the average cost savings for projects using our tool compared to traditional service providers, as these cost savings are now going directly back to the community in the form of increased project success and airdrop distributions.

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

• A GitHub repository hosting the complete source code
• Comprehensive documentation of how to launch the out-of-the-box API, integrate the SDK, and configure and facilitate any type of airdrop using our tool
• Advice, insights, and guides on the best practices surrounding common airdrop 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.

[CAPABILITY & 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?

Yepple has a strong track record of delivering high-quality blockchain solutions since February 2021. Having successfully managed over 200 projects on the Cardano platform over the past three years, we have not only mastered the technology relevant to this proposal but also gained countless invaluable insights into the specific needs of creators of NFT projects and fungible tokens (CNTs). Our team is composed of seasoned blockchain developers, project managers, and strategists who are deeply knowledgeable about the Cardano ecosystem. This experience positions us uniquely to deliver this project with high levels of expertise, trust, and accountability. Several of the projects we have worked with, and the work that we performed for them, can be found on the “contributions” link attached to this proposal. We are also registered as a DRep for Cardano, further showcasing our commitment and dedication to this blockchain.

While Yepple has deployed many solutions on Cardano (minting, token generation, metadata updates, staking, NFT customizers, storefronts, custom dApps), airdrops have stood strong both independently and alongside the other products as one of our most utilized services. Because of this, our team has gained countless invaluable insights into the impact of efficient airdrop processes on community engagement and project success. Some examples of this include our token and/or reward distributions that we have performed for the $BANK team, Evolutions, Walkers, House of Titans, Salty Seagulls, Inmates, Hoarders, Stag Alliance, and many others. Our airdrop tools aim to set a new standard for distributing tokens on Cardano by making our battle-tested technology approachable, easily deployed, and well-documented. These tools, fundamental to successful token distribution for any project on Cardano, will be shared with the community as part of this proposal. We are confident in our ability to provide sufficient support and guidance to drive adoption of this solution, making the process of rewarding their community less intimidating and more accessible to all project owners.

[VALUE FOR MONEY] How does the cost of the project represent value for money for the Cardano ecosystem?

Our proposed budget represents exceptional value for money for the Cardano ecosystem, reflecting more than three years of intensive development by our experienced team. The investment of 110k ADA in open-sourcing these airdrop solutions in a highly practical and accessible package is significantly lower than the industry costs of building a similar robust, secure, and fully-functional airdrop platform from scratch. In particular, when it comes to distributing real value across an immutable ledger, it is essential to utilize technology that has been tested relentlessly as our airdrops have been with the hundreds of thousands of wallets that have received rewards via our distributions. US-based (we are a US company) industry costs associated with such extensive software development and testing could reach several hundred thousand dollars, given the specialized nature of blockchain technology. We are not only offering the Cardano community access to our refined, bulletproof technology but also providing comprehensive documentation. This ensures that even those new to the space can quickly leverage our platform to efficiently distribute NFTs and fungible tokens, thereby enhancing innovation and participation within the Cardano ecosystem. In essence, we are equipping the community with a high-caliber toolset that accelerates development timelines, reduces upfront costs, and fosters greater creativity on the blockchain. The solutions we have provided for the $BANK team, Evolutions, Walkers, House of Titans, Salty Seagulls, Inmates, Hoarders, Stag Alliance, and many others have showcased the adoption, engagement, and community morale that can be obtained through airdrops, which directly translates into value for the projects using the technology as well as the ecosystem and community as a whole.
