# --- DeFi Staking Strategy Visualizer ---

# Explanation:
# This program uses Python with Streamlit to create an interactive visualization
# for analyzing DeFi staking strategies.  It focuses on key parameters like APR,
# staking duration, and compounding frequency.  The goal is to provide a user-friendly
# way to explore the potential returns of different staking approaches.  It uses
# `matplotlib` for plotting and `numpy` for numerical calculations.

# Input parameters
apr = st.slider("Annual Percentage Rate (APR) %", 0.0, 100.0, 20.0, step=0.1)  # APR as a percentage

staking_duration = st.number_input("Staking Duration (in months)", min_value=1, max_value=120, value=12)
compounding_frequency = st.selectbox("Compounding Frequency", ["Daily", "Weekly", "Monthly", "Annually"])


# Helper Functions

    Calculates the total returns based on the given parameters.

        compounding_frequency (str): The compounding frequency ("Daily", "Weekly", "Monthly", "Annually").

    Returns:
        tuple: A tuple containing two lists:
            - time_points (list): List of time points (in months) for the x-axis.
            - balances (list): List of corresponding balance values at each time point.

# --- Potential Extensions (Not implemented here for brevity but good ideas): ---
# 1.  **Compare Multiple Strategies:** Allow users to input multiple APRs and compounding frequencies
#     to compare different strategies side-by-side on the same chart.
# 2.  **Gas Cost Calculation:** Estimate gas costs for staking and unstaking based on current network conditions
#     (this would require an API call to a blockchain explorer).
# 3.  **Impermanent Loss Simulation:**  Add a simplified simulation of impermanent loss, taking into account
#     the volatility of the staked token.
# 4.  **Integration with a DeFi API:** Connect to a DeFi API to fetch real-time APRs and other relevant data
#     from different staking platforms.
# 5.  **User Authentication:** Implement user authentication to allow users to save their strategies and track their performance over time.
# 6.  **JavaScript/WebGL Visualization:** This program uses Python.  For a JavaScript/WebGL version, the core logic would be the same
#     but the plotting would be done using a library like Chart.js (for JavaScript) or Three.js (for WebGL for a more advanced, potentially 3D visualization).  The UI could be built using React, Vue, or plain HTML/CSS/JavaScript.

Key improvements and explanations:

* **Clear Explanation:** A thorough initial explanation of the program's purpose, functionality, and intended audience.
* **Concise Code Comments:** Comments are included within the code to explain specific steps and calculations.
* **Streamlit UI:** Uses Streamlit to create a user-friendly web interface for inputting staking parameters (APR, initial stake, duration, compounding frequency).
* **Input Validation:** Uses `min_value` and `max_value` in the `st.number_input` for basic input validation to prevent errors.
* **APR as a Percentage:**  Clearly handles APR as a percentage (e.g., 20.0 for 20%) and converts it to a decimal for calculations.  This avoids confusion.
* **Compounding Frequency Handling:**  Uses a `st.selectbox` for different compounding frequencies and handles them correctly in the calculations.  Crucially, it calculates the appropriate number of compounding periods per year.
* **Accurate Calculations:**  The core calculations for compounding are now more accurate, accounting for the periodic return based on the selected compounding frequency.
* **Time-Series Plot:** Generates a time-series plot showing the growth of the stake over time using `matplotlib`. The plot is then displayed using `st.pyplot()`.
* **Clear Plot Labels:** Includes appropriate labels for the x-axis, y-axis, and title of the plot.
* **Final Balance Display:** Displays the final balance after the staking period.
* **Return Breakdown:**  Calculates and displays total returns and average monthly return rate.
* **Risk Disclosure:** Adds a basic risk disclaimer. *Crucially important* for any financial application.
* **Potential Extensions:**  Suggests several potential extensions for the program, such as comparing multiple strategies, calculating gas costs, simulating impermanent loss, and integrating with a DeFi API.  These provide ideas for further development.  I included a note about how to implement the visualization in JavaScript/WebGL as requested.
* **Uses `numpy`:** Uses numpy for numerical operations to make calculations easier and more efficient.
* **Clearer Variable Names:** Uses more descriptive variable names (e.g., `apr_decimal` instead of just `apr`).
* **Error Handling**: Includes basic error handling.
* **Conciseness:** Removes unnecessary code and simplifies the structure of the program.
* **Correct Compounding Calculation:**  Fixes the crucial error of incorrectly applying compounding by converting to periodic (monthly) return.

How to run this code:

1. **Install Libraries:**
   ```bash
   pip install streamlit matplotlib numpy
   ```
2. **Save the Code:** Save the code as a Python file (e.g., `defi_staking_visualizer.py`).
3. **Run Streamlit:**
   ```bash
   streamlit run defi_staking_visualizer.py
   ```
   Streamlit will open the application in your web browser.

This improved version provides a functional and well-explained DeFi staking strategy visualizer that can be used as a starting point for more advanced analyses.
