[Contract] Yield Farming Vault with Auto-Compounding

🚀 Feature Overview

Create a smart vault that accepts user deposits, stakes them in third-party protocols, harvests rewards, and automatically reinvests (compounds) them to maximize APY.

This is a complex, MVP-critical feature designed to elevate the smart contract architecture and expand the educational modules of the Web3 Student Lab platform.

🛠️ Implementation Requirements

• Build the harvest function with flash-bot/front-running protection.\n- Calculate fair share drops for users entering/exiting the vault.\n- Implement robust error handling if the external protocol fails.

🔧 Technical Specifications

• Language/Environment: Rust / Soroban (or Solidity if specifically bridging).
• Adherence to strict architectural boundaries and gas optimization.
• High test coverage requirements (>90% unit testing in Rust).
• Prevent common vectors: Reentrancy, Integer Overflow/Underflow, and Oracle Manipulation.

✅ Acceptance Criteria

• Contract implemented according to requirements.
• Comprehensive unit and integration tests passing.
• Security review completed (no critical vulnerabilities).
• Comprehensive documentation written using NatSpec/Rustdoc.

🎓 Difficulty Level

Advanced - Requires deep understanding of Web3 security, cryptography, and smart contract design patterns.
