Please describe your proposed solution

Mass adoption of DeFi heavily depends on the liquidity of the ecosystem. High-frequency trading solutions are efficient in bridging the liquidity between investors and traders, improving trading volume within the Cardano ecosystem. Order management fees and order confirmation are the major blockers in the Cardano ecosystem due to the nature of the UTXO model.

Our proposed solution is categorized into two parts:

<u>Off-Chain Order Matching</u>

DeltaDeFi develops a virtual order book. Through the off-chain order matching engine, trade execution can be completed instantly, without sacrificing the decentralization benefits of the blockchain as we are a non-custodial platform. This system allows for high transaction throughput, minimizing latency and reducing the order creation, and cancellation costs.

<u>On-Chain Settlements</u>

While the order matching occurs off-chain, all trade settlements are submitted to the Cardano blockchain, ensuring efficiency and security for all transaction

Besides, our virtual order book system introduces a non-custodial, chain-agnostic architecture that supports any UTxO-compatible blockchain, indicating the consideration of scalability and interoperability.

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

<u>Boosting Cardano’s Appeal to Institutional and Professional Traders</u>

What's Happening: We're aiming to bring High-frequency Trading (HFT) to Cardano.

Big Picture: Targeting a slice of the massive $30 trillion global crypto trading pie (even more when the bull market arrives).

Core Benefit: Attract heavy hitters - think institutional and professional traders. This means more trading on Cardano, more growth, more buzz.

<u>Liquidity Surge, Ecosystem Thrive</u>

What's Happening: HFT players trade big, trade fast.

Big Picture: They're the market's oil - making buying and selling smoother for everyone.

Core Benefit: Reduced bid-ask spreads, healthier market, more money flowing. It’s like opening the floodgates for Cardano's DEXes, boosting their trade volume.

<u>Open Source Contributions</u>

Full documentation will be open-source. SDK will be publicly available.

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 has strongly committed and experienced members, providing all required skill sets and expertise to successfully implement the proposed solution

Trust and accountability:

• Track record on Cardano ecosystem participation
• Team members have a track record of contributing in Cardano open source such as Mesh feature improvement, research Cardano techniques with sharing on Gimbalabs.
