It allows users to deposit Bitcoin, automatically allocates funds to the most efficient yield protocols, and calculates accrued yields over time. With robust risk management features, including protocol deactivation and allocation limits, YieldForge ensures secure and efficient yield aggregation. Built with clarity and precision, the contract offers users a transparent and trustless way to maximize their Bitcoin returns. + +--- + +## Features + +1. **Protocol Management**: + + - Add new yield protocols with customizable parameters such as base APY and maximum allocation percentage. + - Deactivate protocols to manage risk and ensure system integrity. + +2. **User Deposits**: + + - Deposit Bitcoin into supported yield protocols. + - Track user deposits and calculate accrued yields over time. + +3. **Yield Calculation**: + + - Simplified yield calculation based on protocol APY and deposit duration. + - Real-time yield estimation for user withdrawals. + +4. **Withdrawals**: + + - Withdraw deposited Bitcoin along with accrued yields. + - Ensure sufficient funds and enforce protocol constraints. + +5. **Risk Management**: + + - Deactivate protocols to prevent further deposits. + - Enforce maximum allocation limits to prevent overexposure. + +6. **Input Validation**: + -
