Please describe your proposed solution.

Our proposed solution is to enable people to log in with their AdaHandle, rather than needing to restore their wallet into the app, or creating a new wallet within their account in the app.

We will implement a simple way for people to input their adahandle, to then be prompted for verification of their address. Adahandles will be used to confirm a users wallet which we can then import assets from.

This will enable users to see their NFTs in their wallet and they will be able to use Ticket and Pass tokens without requiring them to share their wallet security credentials with the app

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

We can help establish a standard for verifying wallet ownership without importing wallets, by integrating the AdaHandle standard already implemented on the Cardano blockchain.

Using existing systems to improve security for users and projects will help improve the general UX of the blockchain ecosystem and releasing this verification mechanism to the public will enable other projects to follow suit when wallet verification can be used instead of importing it into other applications built to use the Cardano blockchain

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

We will measure success for this project by the completion and security testing of this feature, initially.

This will then be integrated into the main application and will undergo real world tests with users at events on Cardano next year.

A key thing we will be looking at is adoption of this verification process over the next year. We expect to see consistant growth to come with each test at Cardano events this year.

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

• Build Backend tools to import wallets into users accounts through their adahandle.
• Implement verification mechanism into the backend
• Create an appropriate representation of this in the UI of the mobile app
• Test verification mechanism
• Roll out the release into the mobile app

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

Our team has already built the alpha version of the NftPass app, from blockchain integration to ui development, we have experience in mobile development, blockchain tools and backend development.

With a strong team of experienced and successful individuals, our combined experience and skills will help us with everything from development to testing and expanding the business outside of crypto

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

The main goal is a simple mechanism for connecting a wallet to a user account without restoring it, mitigating potential security risks.

We will validate our approach is feasible with tests composed on the preview / preprod network where we try to manipulate the mechanism to show the wrong wallet, or display a different users wallet.

These tests will help us find unforeseen security risks in the mechanism and will allow us to address them before anything is deployed to mainnet.

Once these initial securty tests are completed we will role out tests at Cardano events this year to progressively stress test the system.

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.

There are several parts of this proposal that we will split into the following milestones:

M1 - 1 Month:

• Build Backend tools to import wallets into users accounts through their adahandle.
• UI Design work

M2 - 1 Month:

• Implement verification mechanism into the backend
• App development for the implementation of the solution

M3 - 1 Month:

• Test verification mechanism for potential security risks and exploits
• Roll out the release into the mobile app

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

Deliverables include:

• Adahandle connection mechanism to a user's account
• Open source verification tools for other projects to implement the same or similar solution
• Marketing video of the solution
• App demo teaching people how to verify in app

Intended outcome is a secure method for integrating Cardano wallets to our app.

Output is the ability for Cardano users to keep their wallets secure and use NFT tickets for event access and passes.

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

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

Security is one of the most beneficial areas to spend money on, our application will create a novel solution to allow not only our project but others to verify wallet ownership for accounts on their service with absolutely no security risk.

Not all apps and services need you to send tokens, NFTPass is a good example of this; The purpose of this proposal will enable users to verify ownership of wallets for the application to use, without exposing the wallet to the security risks associated with importing it.

Such a standard is necessary for the ecosystem, and the use of the AdaHandle standard is perfect for implementing with this mechanism. This will enable better options for future projects and services that require the same level of ownership verification.
