About

#### **Introduction** RWA Vault is a next-generation DeFi protocol on Mantle, designed to bridge the gap between decentralized finance and real-world assets (RWAs). It leverages the ERC-4626 tokenized vault standard to provide users with a seamless and innovative way to gain exposure to RWAs while maximizing yield potential. #### **Core Features** 1. **Tokenized Vault (RWA Vault)** - Users deposit assets into the RWA Vault and receive ERC-4626-compliant vault shares. - The vault’s underlying asset is a dynamically managed basket of RWAs. - Share prices reflect the performance of the vault’s portfolio, adjusting based on the value of the underlying assets. 2. **Performance Metrics** - **Deposit Rate:** `totalSupply / totalAssets` - **Withdrawal Rate:** `totalAssets / totalSupply` - **totalSupply:** Represents the total circulating shares of the vault. - **totalAssets:** Consists of: - **Cash:** Undeployed capital ensuring continuous liquidity for user withdrawals. - **AUM (Assets Under Management):** The deployed capital value in RWAs, updated by an Oracle Manager. 3. **RWA Leverage Extension** - Allows users to lock their vault shares for a fixed period. - Locked shares can be leveraged to borrow additional funds, subject to vault liquidity. - Users benefit from increased returns but incur penalties for late repayments. - Managed by a **Liquidity Manager** who ensures loan health and liquidates risky positions. #### **Key Roles** - **Oracle Manager:** Regularly updates the vault’s AUM, impacting share price calculations. - **Liquidity Manager:** Monitors and manages active loans, ensuring optimal liquidity usage and risk mitigation. #### **Innovative Aspects** - **Enhanced Liquidity Management:** Continuous liquidity through cash reserves ensures users can withdraw anytime, while planned capital lockups optimize deployment. - **Dynamic Yield Mechanism:** A flexible framework that adjusts based on real-time asset performance. - **Leverage Incentives:** Encourages user participation by offering leveraged positions with structured risk management. #### **Use Cases** - **Institutional and Retail Investors:** Seamless exposure to real-world assets with dynamic risk-return profiles. - **Borrowers:** Access to liquidity backed by locked-up shares. - **DeFi Ecosystem Growth on Mantle:** Demonstrates the potential of combining RWA tokenization with cutting-edge DeFi mechanics.

How it's made

**Framework and Tools** I built the project using the **Hardhat framework**, a versatile development environment for Ethereum-based projects. It provided the foundation for writing, testing, and deploying smart contracts efficiently. **Smart Contract Development** I leveraged **OpenZeppelin’s ERC-4626 tokenized vault implementation** as the core of the project. This standard ensured a robust and secure vault design, simplifying the process of creating yield-bearing tokenized assets while adhering to industry best practices. **Development Process** 1. **Project Setup** I initialized the project using Hardhat, configured the environment, and installed necessary dependencies, including OpenZeppelin’s libraries and testing tools. 2. **Smart Contract Implementation** - Developed the **RWA Vault** contract, utilizing the ERC-4626 standard to manage vault shares and RWAs. - Built the **RWA Leverage** extension, allowing locked shares to be leveraged for additional liquidity. - Integrated roles like the **Oracle Manager** for AUM updates and the **Liquidity Manager** for active loan monitoring. 3. **Writing Test Cases** I wrote comprehensive tests using **Mocha** and **Chai** to ensure the correctness of deposit/withdrawal logic, share price calculations, and leverage mechanisms. This included edge cases to validate the robustness of the Oracle and Liquidity Managers. 4. **Deployment Scripts** I crafted custom deployment scripts to automate the deployment process. These scripts ensured smooth contract deployment on the **Mantle testnet**, verifying that all components were operational and properly configured. 5. **Testnet Deployment and Dry Run** - Deployed the contracts on Mantle’s testnet, simulating real-world interactions. - Conducted a dry run to evaluate system performance under different scenarios, including high withdrawal demand and stress testing of the leverage feature. **Hacky Highlights** - **Dynamic AUM Calculation**: A notable innovation was the integration of a custom Oracle system to regularly update the vault’s AUM, ensuring real-time share price adjustments. - **Flexible Liquidity Management**: By separating cash reserves and deployed capital, I maintained continuous liquidity for withdrawals while maximizing yield potential. - **Optimized Gas Usage**: During testing, I identified and optimized high-gas functions, significantly reducing transaction costs. **Partner Technologies** - **OpenZeppelin**: The ERC-4626 implementation provided a secure and standardized foundation, saving development time and ensuring compatibility with DeFi tools. - **Mantle Network**: Deploying on Mantle allowed me to leverage its scalability and low fees, ensuring an optimal user experience. This approach ensured a well-structured, secure, and efficient project build, aligning with Mantle’s goal of pushing the boundaries of DeFi innovation.
