[SOLUTION] Please describe your proposed solution.

The Optim-Account is a natural and ambitious extension of Optim's innovative implementation of transaction chaining combined with other on and off chain optimizations live and in use for Optim's Liquidity Bonds product(live for 1 year with 70 Million ADA successfully transacted)

A prototype of the Optim-Account is seen on our currently deployed Dapp, the Optim Bonds. The application takes advantage of the future state of the blockchain and makes use of it in the present, using a bespoke offchain technology that ensures rollback and fork coherence in the process. We will continue to leverage this technology and in fact have made strives in pushing it to the utmost theoretical limit of scalability. This is what the Optim Account aims to achieve, and this is the core of our scaling improvement plan around the Optim Account. The other features of it center around improving the developer experience and pushing beyond what apps on Cardano can achieve.

The concept of Optim-Account is conceived as a response to inherent limitations within Cardano's existing architecture, particularly addressing issues related to transaction concurrency and composability limitations arising from deterministic processing. Rooted in a comprehensive understanding of blockchain mechanics and user experience, the Optim-Account system introduces a paradigm shift in how transactions are structured and executed within the Cardano ecosystem.

At the core of the Optim-Account system is the concept of intent-based transactions, which diverges from traditional direct blockchain transaction submissions. Users articulate their transactional goals as 'intents', a digital method of conveying desired outcomes without immediately initiating on-chain operations. These intents offer a simpler, more abstract yet precise interaction with the blockchain, easing complexity.

Intent-Based Transactions focus on specifying the "what" rather than the "how" of desired outcomes. Traditional transactions require users to define every parameter, but intents allow users to state their end goals and leave execution to 'solvers'. For example, traditional transactions might demand "do A then B, pay C to get X," while intent-based transactions would simply state "I want X and am willing to pay up to C", letting solvers handle technical details.

The process of conveying user intents in the Optim-Account is akin to sending messages. Users articulate their transactional needs in the form of these messages, which encapsulate the essence of their intended blockchain interactions. This abstraction not only simplifies the user experience but also enhances the system's efficiency.

By decoupling the user's direct engagement with the blockchain's intricacies, the system effectively opens the door to a more intuitive and accessible blockchain experience, even for users who may not possess extensive technical knowledge of blockchain operations.

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

The Optim-Account system marks a significant advancement in the Cardano ecosystem, addressing key challenges like transaction efficiency and composability. By integrating sequencers and intent-based processes, it addresses issues like concurrency and resource contention, offering a practical approach to enhancing Cardano’s capabilities. This system is an important step in evolving blockchain interactions, combining technical improvements with a focus on user needs.

As the system approaches its Mainnet Beta release, it aspires to contribute positively to the Cardano ecosystem. This upcoming release is an important milestone, focusing on functional deployment while emphasizing stability and security in blockchain transactions.

By acting as a virtual ledger layer that integrates relatively easily into Cardano’s existing architecture and infrastructure, dApps and Cardano users can derive value and expect a widespread impact on the ecosystem. Composable dApps and account abstraction are just a few of the user experience improvements that the Cardano community can expect.

We will measure impact in a number of ways

• Number of dApps using the Optim-Account model

• Amount of ADA transacted via Optim-Account dApps

• New use cases and DeFi functions enabled by Optim-Account

• Number of Optim-Accounts created

• Amount of ADA held in Optim-Accounts

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

Deliver the completed design and documentation of all feature extensions that bridge beyond Optim's current tx chaining and offchain systems architecture to what can be considered a more complete and scalable Optim-Account implementation.

Milestone outputs include documented public Gitbook and Github access showing all system components.

>Deliver the basic feature extensions, bridging beyond Optim's current tx chaining and offchain systems architecture to a fuller Optim-Account implementation showcasing the main features of the system.

Milestone outputs include on and off chain proof of a working sequencer, intents, and basic account-based actions such as gas and autonomous transactions working on testnet.

>Complete an audit of the Optim-Account system after a successful testnet of the basic features and first dApp deployment. Also undergo additional code review and audit of any changes and fixes to contracts resulting from initial audit.

Milestone outputs will be two comprehensive public audit reports (initial audit + audit of fixes/ changes)

>Showcase the first dApp using the basics of the Optim-Account architecture during a functioning mainnet Beta.

The milestone will be confirmed by implementing a useable dApp whereby a user can feed tx fee gas into an Optim-Account then have it execute automatic, intermittent airdrop claims autonomously based on eligible Liquidity Bonds confirmed in wallet.

>Extend the Optim-Account model to include capabilities for more complex inter-dApp interactions showcasing advanced composability and settlement with increased transaction speeds from increased sequencer throughput.
