[SOLUTION] Please describe your proposed solution

Understanding the Problem: The Cardano ecosystem currently lacks a mechanism for recurring payments, a critical functionality for businesses and services looking to offer subscription-based models. This limitation restricts the potential for diverse business models and hinders the broader use of ADA for continuous transactions.

Our Unique Approach - AMPDsub: AMPDsub is designed as a Smart Escrow Wallet (SEW) system, akin to a prepaid credit card, which integrates with Cardano's blockchain. This approach uniquely combines security, flexibility, and user control, addressing the existing gap in the ecosystem.

Key Features of AMPDsub:

• Smart Contract Subscription System: Utilizes AIKEN’s capabilities to create a secure and straightforward subscription mechanism.
• Security and User Control: The SEW doesn’t directly access user wallets, instead, it securely stores subscription details as metadata, ensuring funds are only used as per the user's subscription choices.
• Flexibility in Subscription Management: Users have complete control over their subscriptions, with the ability to initiate, modify, or cancel at any time.
• Frankenaddress Feature: Maintains the staking benefits associated with a user's wallet while using the escrow service, ensuring users don't miss out on staking rewards.

Engagement and Impact:

• Target Audience: Both businesses seeking to offer subscription services and users desiring a more flexible payment option on the Cardano blockchain.
• Demonstrating Impact: By enabling a new stream of revenue models through ADA-based subscriptions, AMPDsub will demonstrate its impact through increased business adoption and user engagement within the Cardano ecosystem.

Why It's Important to Cardano: AMPDsub's introduction of a recurring payment system is pivotal for expanding Cardano’s utility in the digital economy. It opens up opportunities for a variety of subscription-based services and businesses, encouraging innovation and fostering a more dynamic and inclusive financial ecosystem on Cardano.

This solution addresses both the technical challenge and the practical needs of the Cardano community, making it a significant step towards enhancing the blockchain's usability and appeal.

[PROJECT MILESTONES] What are the key milestones you need to achieve in order to complete your project successfully?

Smart Contract Development and Deployment

This milestone focuses solely on the core of project revolving around the contract development, auditing and deployment with supported APIs.

Marked done once the following items are completed:

1. Contract finalized with all necessary requirements
2. Contract audited and deployed on test net
3. APIs for interacting with contract and returning relevant contract data deployed

UI/UX Development and Pre-Production Deployment

This milestone focuses on the overall user portal and the UI/UX for the project.

Marked done once the following items are completed:

1. Design and implement the UI/UX for a proof of concept to demonstrate the smart contract's features with the developed apis from milesonte 1 (this is a ui/ux update)
2. Setup backend infrastructure for contract management for fast retrieval and storing relevant subscription information to limit requests needed from a user perspective.
3. Simple user creation and recurring payment creation with testnet contract

Final Audit and Pre Launch Security Testing

A focus on ensuring the contract is solid and making any more improvements for optimization as well as site management to handle load requirements before pushing to public. (Upgrading servers if need be as well as hosting)

Marked done once the following items are completed:

1. Second audit is approved with a focus not just on the contract but on the site itself for vulnerabilities in APIs or other ways to hack it
2. Site and backend migrated if need be to more robust systems
3. Platform approved for mainnet migration
4. Open source code for contracts and dapp itself. (this will also allow for a better management of bug reporting in the alpha)

Integration into AMPD Ecosystem and Launch

This is the actual soft launch with wallet gated access on mainnet before pushing to public launch.

Marked done once the following items are completed:

1. Migrate users to AMPD wallet for an easier wallet solution management
2. Open an alpha to select wallets and allow access for atleast 1 week - 2 weeks of alpha use and updates as needed.
3. Overall results are as expected, major bugs fixed, and can at best guarantee a stable, secure and smooth user platform.

Next is whatever the future holds, but with these milestones this will guarantee a focus on contract first, then ui/ux, then scalability and robustness and internal testing, then testing on an external solution with valuable feedback, and will ensure a successful and much needed product for the Cardano ecosystem.
