Introduce YieldForge: Decentralized Bitcoin Yield Aggregation Contract

[ud-cmd]

Description

This pull request introduces YieldForge, a decentralized yield aggregation smart contract designed to optimize Bitcoin yield generation across multiple DeFi protocols. The contract enables users to deposit Bitcoin, automatically allocates funds to the most efficient yield protocols, and calculates accrued yields over time. It also includes robust risk management features such as protocol deactivation and allocation limits to ensure system integrity and security.

This PR lays the foundation for YieldForge by implementing core functionalities, including protocol management, user deposits, yield calculation, withdrawals, and risk management. It also includes comprehensive input validation and error handling to ensure a secure and user-friendly experience.

Key Features Added

1. Protocol Management

• Added the add-protocol function to register new yield protocols with customizable parameters such as base APY and maximum allocation percentage.
• Implemented the deactivate-protocol function to allow the contract owner to deactivate protocols, ensuring risk management and system stability.

2. User Deposits

• Introduced the deposit function to allow users to deposit Bitcoin into supported protocols.
• Added storage for tracking user deposits and protocol total deposits.

3. Yield Calculation

• Implemented the calculate-yield function to compute accrued yields based on deposit duration and protocol APY.

4. Withdrawals

• Added the withdraw function to enable users to withdraw their deposited Bitcoin along with accrued yields.
• Ensured validation checks for sufficient funds and protocol constraints.

5. Risk Management

• Enforced maximum allocation limits to prevent overexposure to any single protocol.
• Allowed protocol deactivation to manage risk and maintain system integrity.

6. Input Validation

• Added comprehensive validation for protocol IDs, deposit amounts, and user inputs.
• Ensured only the contract owner can add or deactivate protocols.

7. Initialization

• Implemented the initialize-protocols function to set up default protocols with error checking.

Changes Included

1. Error Constants:

   • Defined error constants for various failure scenarios, such as unauthorized access, insufficient funds, and invalid inputs.

2. Storage Structures:

   • Added storage for supported protocols, user deposits, and protocol total deposits.

3. Input Validation Functions:

   • Implemented validation functions for protocol IDs, protocol names, base APY, allocation percentages, and deposit amounts.

4. Core Functions:

   • Added add-protocol, deposit, calculate-yield, withdraw, and deactivate-protocol functions.

5. Initialization:

   • Added the initialize-protocols function to set up initial protocols.

6. Documentation:

   • Included a detailed README explaining the purpose, functionality, and usage of the YieldForge smart contract.
