Please describe your proposed solution

HandlePay Framework is an all-in-one easy-to-use Android and iOS mobile application that utilizes Handles for transacting on the Cardano blockchain.

Our goal is to build an application framework that resembles Venmo/CashApp/Splitwise. In other words, an intuitive application with built-in chat to allow users to efficiently communicate about specific transactions.

We at ADA Handle are already building HandleChat that will enable communications utilizing $handles. HandlePay Framework will integrate HandleChat to enable the communications layer for this new application.

This proposal is for the first portion of the HandlePay solution. It focuses on creating the framework for the applications. A future proposal (Fund14) will create the UI/UX for Android and iOS. In other words, this first phase (framework) will create the software base layer and the next proposal (Fund 14) wil be for the development of the User Interface on Android and iOS.

$handles are the leading naming service on Cardano. We have sold nearly 250,000 Handles. An application framework that creates an open-source solution for $handles to transact with ease is, therefore, something that we believe that will greatly benefit the Cardano community.

Key Features:

• Custom Handle Creation: Users can create personalized handles linked to their blockchain addresses. Handles can be customized to reflect usernames, business names, or any preferred identifier.
• Seamless Transactions: The app allows users to send and receive ADA, Cardano-native tokens, and at some point domestic/foreign currency.
• Handle Marketplace: Users can buy, sell, and trade custom handles within the application, creating an additional economic layer. High-value, rare, or brand-relevant $handles can be monetized directly from HandlePay.
• Integration with Cardano dApps: The app will integrate with DEX’s on Cardano, allowing users to buy and sell digital assets from DeFi platforms, NFT marketplaces(?), and other blockchain services.
• Enhanced Security: Leveraging the Cardano blockchain’s robust proof-of-stake protocol, transactions via $handles remain secure, decentralized, and immutable.
• Cross-platform Availability: The app will be available on both iOS and Android devices, ensuring accessibility for a broad audience.

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

Cardano is rapidly growing, with over 1,000 projects being built on the platform. Our app is positioned to target a user base of both current blockchain users and the broader public seeking easier access to decentralized finance. The global blockchain market is projected to experience substantial growth in the coming years. According to a report published in December 2021, the market size was expected to expand from $4.9 billion in 2021 to $67.4 billion by 2026 (GlobeNewswire). At Kora Labs we are acutely aware that this growth is not linear but instead works in cycles, where we observe a large influx of new users every four-or-so years. We recognize the need for a simple, efficient, and easy-to-understand mobile application that will be positioned to capture that influx of new users. HandlePay is that app.

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 is composed of highly skilled engineers that joined Cardano specifically to build ADA Handle. Our C-level team is composed of BigIrishLion (<https://twitter.com/bigirishlion>), Papa Goose (<https://twitter.com/papagoosecrypto>), Mr. Goose (<https://twitter.com/gooseofcrypto>) and Conrad (<https://twitter.com/conraddit>), in addition to a number of contractors and board members. Combined, we have over 100 years of development experience.

ADA Handle was created from an idea. We did not have any experience building on Cardano. But we got the job done. We started building ADA Handle in June 2021 and by December 2021 we launched our Beta sale. Within 12 hours we sold out the 15,000 beta-sale assignments that we had set as our initial goal. Since then we have launched our public sale and have sold nearly 250,000 Handles. Our minting engines operate 24x7, with an uptime of 99.99%.

In the process of launching ADA Handle, our team learned how to program with Plutus V1, V2 and V3, Helios, Aiken. We built our own multi-sig wallet. Our team has launched a public API, that is available free-of-charge for the entire Cardano community, on the three public blockchains: Preview, PreProd and MainNet. The community can attest to this by accessing their corresponding endpoints:

Preview: <https://preview.api.handle.me/swagger>

PreProd: <https://preprod.api.handle.me/swagger>

MainNet: <https://api.handle.me/swagger>

Our API was developed in an open-source distribution, available for the community to download and run a local copy, should they wish to, instead of running our public endpoints. We understand that some projects might have this need, of running the API within their own systems and infrastructure, and for this reason we also made it open source, including examples of deployments, for all 3 blockchains. The public API is available from this GitHub Repository: <https://github.com/koralabs/handles-public-api>.

In addition to making available to the Cardano community a free and open-source API endpoint, we have also developed clear and concise documentation explaining the resolution process for Handles, utilizing the current and old standards, CIP-68 and CIP-25, in addition to the soon-to-be-delivered subHandle standard. This documentation can be viewed from this link: <https://public.koralabs.io/documentation/HandleResolution.pdf>.

Our minting portal, for all three blockchains, with an uptime of over 99.99%, can also be verified from these links:

Preview: <https://mint.handle.me>

PreProd: <https://preprod.mint.handle.me>

MainNet: <https://mint.handle.me>

We have also concluded the first phase of our Marketplace, as per the Fund10 Handle Marketplace, which can be verified from these links:

Preview: <https://preview.marketplace.handle.me/backgrounds>

PreProd: <https://preprod.marketplace.handle.me/backgrounds>

This was the first Milestone of the Catalyst proposal from Fund 10, and, as per the proposal, only Preview and PreProd would be launched by now, which we delivered on-time and within the stipulated budget. MainNet is also mostly ready as well, and we'll launch it soon.

This document is another evidence of our capabilities to develop and build solutions within Cardano, as it contains all the parameters and settings for the community to utilize our marketplace and background-development tool to create their own backgrounds, matching the requirements to make them compatible with Handles: <https://public.koralabs.io/personalization/Handles+Background+Creator+Defaults.pdf.>

subHandles are now live on all 3 blockchains (Preview, PreProd, MainNet), with the general public minting virtual and NFT-based Handles from: https://handle.me.

We have, therefore, demonstrated our capabilities in building systems, developing Cardano-based technologies, and perhaps most importantly, the ability to engage with the Cardano community and generate traffic to our protocol and solutions.

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

$handles are the leading naming service for the Cardano blockchain with nearly 250,000 Handles minted.

We have been building the $handle protocol since 2021, supporting Cardano and the Cardano Community for over 3 years.

$handles are integrated to all major wallets, multiple dApps and 10s of other services.

There are over 60k independent wallets holding at least one Handle.

Based on these metrics, one could argue that ADA Handle is the most successful project on the Cardano blockchain.

HandlePay is the logical next step to further develop the ADA Handle protocol, building easy-to-use mobile applications for Android and iOS.

Thus, the proposed value-for-money metric is to help Cardano further by delivering fast, seamless, modern UI/UX for the mobile users.
