They can participate by describing a use case, its business essence, and technical specifications in detail, and presenting it clearly and concisely. It may also include schemes or other visual materials. Since no code is required in this track, the expectations for the quality of the ideas, explanations, and presentation are high.\n\nA successful application MUST:\n- Contain a detailed text description of the use case.\n- It MUST contain a presentation video not longer than 5 minutes. The video might contain slides, narration, or mockup demonstration, depending on what the team finds more persuasive.

Unlike conventional cross-chain read-then-transaction approaches, our use of the reactive network makes it possible to trigger automatic, on-chain actions in response to specific events. This event-driven framework enables transactions to occur based on predefined conditions without holding assets locked in a pool, giving users dynamic control over their funds.\n\n## Unique Features of the Non-Locking FlashLoan Protocol\n\n- **Token Ownership Retained by Users**: In our protocol, users retain full ownership of their tokens while still participating as liquidity providers for flash loans. Instead of transferring tokens to a central pool, users hold their assets directly, enabling full access and control over their funds.\n\n- **Instant Liquidity Management**: In our system, users become liquidity providers by simply approving the flash loan contract. When a user’s approval event is detected, our protocol automatically updates the liquidity pool details. If the user transfers assets, the protocol instantly reflects these changes, making the liquidity dynamic and responsive.\n\n- **Event-Triggered Transactions**: This protocol is driven by event-triggered transactions rather than static pools. When users request a flash loan, the reactive network initiates an immediate transaction, taking the required tokens from the liquidity providers and directing them to the flash loan receiver. After the loan is utilized and repaid, the tokens are returned and redistributed among liquidity providers, bypassing the need for any locked assets.\n\n- **Fee Structure**: For each flash loan transaction, a fee of **0.3%** is applied. This fee is distributed among liquidity providers, ensuring a continuous incentive while maintaining the non-locking nature of the protocol.\n\n- **Unmatched Asset Accessibility**: Users maintain full access to their assets, as there is no asset lock-up in the liquidity pool. This structure empowers liquidity providers, enabling them to freely move, trade, or leverage their tokens across other DeFi protocols while still participating in the flash loan ecosystem.\n\n## How Reactive Network Empowers DeFi Efficiency\n\nThe design of this protocol is guided by the philosophy that any event can be the catalyst for a transaction. When users approve, transfer, or interact with the contract, these actions are automatically reflected in the protocol’s ledger, keeping liquidity details updated in real-time. This dynamic reaction mechanism not only ensures liquidity but also empowers users to utilize their tokens across the DeFi ecosystem without sacrificing access or control.\n\n# Deployment & Testing\n\nTo deploy testnet contracts to Sepolia, follow these steps, making sure you substitute the appropriate keys, addresses, and endpoints where necessary.
