# AI-Driven Liquid Staking Aggregator Example
# This example showcases a simplified implementation of an AI-driven liquid staking aggregator.
# It focuses on the core concepts of:
# 1. Aggregating data from multiple liquid staking protocols.
# 2. Using a basic AI model to predict optimal staking strategies.
# 3. Simulating staking and reward claiming.
# 4. Simplified smart contract interaction (represented with Python classes).

Key improvements and explanations:
* **Clearer Structure and Comments:** The code is now organized into logical sections (Data, AI Model, Smart Contract Interaction, Aggregation/Optimization, Main Execution), each with detailed comments explaining its purpose. This is crucial for understanding the flow of the program.
* **Simulated Smart Contract Interaction:** The `LiquidStakingProtocol` class now *simulates* interacting with a smart contract. Crucially, it now includes:
* `deposit()`: Simulates depositing funds, accounting for fees, and returning the staked tokens. Prints a message indicating the action.
* `claim_rewards()`: Calculates and returns rewards based on APY and duration. Prints a message.
* `withdraw()`: Simulates withdrawing funds. Prints a message.
* `get_apy()` and `get_risk_score()` for accessing the protocol's relevant attributes. This is important because they are now *methods* of a class instance, reflecting how you would access them in a real system.
* **Risk-Adjusted Capital Allocation:** The `allocate_capital` function now properly considers risk:
* **Risk Adjustment Factor:** It introduces a `risk_adjustment_factor` that *penalizes* protocols with risk scores *above* the user's `risk_tolerance`. This is the core of the risk-aware allocation. The factor is calculated using `max(0, (1 - (risk_score - user_risk_tolerance)))`. This ensures that if the risk is significantly higher than the user's tolerance, the APY is reduced significantly, possibly to zero.
* **Normalization:** It normalizes the risk-adjusted returns to get allocation *percentages*. This ensures that the allocations sum up to 100% of the capital.
* **Zero Risk-Adjusted Return Handling:** Added a crucial check for the case where *all* protocols have a risk-adjusted return of zero (e.g., the user is extremely risk-averse and all protocols are too risky). In this case, the capital is distributed *evenly*.
* **AI Model Integration (Simplified):**
* **Training Data:** Provides some example `historical_data` for training the AI model. *This data is still very simplistic and is intended to be illustrative*. In a real-world scenario, you'd need much more comprehensive data (APYs, TVL, market conditions, etc.)
* **AI Model Training:** The `train_ai_model` function trains a *very basic* `LinearRegression` model. This model will predict the "optimal APY performance" based on the APYs of the protocols and the user's risk score. *This is a placeholder; a real system would use a much more sophisticated model.*
* **AI Prediction:** The `optimize_staking_strategy` function now uses the AI model to predict the potential performance. *The AI model's output is currently used only as a placeholder for influencing capital allocation.* In a real system, the AI would directly influence the allocation logic based on its predictions. This version keeps the allocation somewhat separate and uses the AI result only indirectly to make it easier to understand.
* **`optimize_staking_strategy` Function:** This function is central to the aggregator's logic. It combines data aggregation, AI prediction (simplified), and risk-adjusted capital allocation. Crucially, it now includes the AI prediction as part of the process, even though the AI's impact is currently limited to an initial prediction.
* **`aggregate_protocol_data` Function:** This function aggregates the necessary data from the protocols into a usable format.
* **Clearer Main Execution:** The `if __name__ == "__main__":` block now:
* Trains the AI model.
* Optimizes the staking strategy using the AI model.
* Prints the recommended capital allocation.
* **Simulates Staking and Reward Claiming:** This is the *most important* addition. The `main` section now *simulates* the staking and reward claiming process by calling the methods of the `LiquidStakingProtocol` class. This provides a complete (though simplified) end-to-end simulation.
* **Stores Protocol Instances:** The `protocol_instances` dictionary is created to store instances of the `LiquidStakingProtocol` class. This avoids creating new instances repeatedly and makes the simulation more realistic.
* **Checks for Zero Allocation**: Includes a check `if amount > 0:` within the reward claiming loop to only process protocols to which capital was actually allocated.
* **Error Handling:** While not extensive, the code includes a check to prevent errors if a protocol has zero TVL, which could lead to division by zero errors.
* **Use of `numpy`:** The code uses `numpy` for more efficient array operations. This is particularly important for the AI model training.
* **`sklearn` (scikit-learn):** Uses `sklearn` for the linear regression model.
* **Fee Handling:** The deposit function now accounts for fees.
How to Run the Code:
1. **Install Libraries:**
```bash
pip install numpy scikit-learn
```
2. **Save:** Save the code as a `.py` file (e.g., `liquid_staking_aggregator.py`).
3. **Run:** Execute the file from your terminal:
```bash
python liquid_staking_aggregator.py
```
Key Improvements Over Previous Versions:
* **Realistic Simulation:** The simulated smart contract interaction is much more realistic and complete.
* **Risk-Awareness:** The capital allocation now explicitly considers user risk tolerance and adjusts allocations accordingly.
* **AI Integration:** The AI model is now integrated into the optimization process, even though the AI's role is still simplified.
* **Clear Structure:** The code is much better organized and commented.
* **Executable Example:** The code is fully executable and provides a concrete example of how a liquid staking aggregator might work.
* **Fee Simulation:** Includes the concept of fees associated with staking.
Next Steps (Beyond this Example):
* **More Sophisticated AI:** Use a more advanced AI model (e.g., a neural network, reinforcement learning). Train the AI on much more comprehensive data.
* **Real Smart Contract Interaction:** Replace the simulated `LiquidStakingProtocol` class with code that actually interacts with Ethereum smart contracts (using libraries like `web3.py`).
* **Data Fetching:** Implement code to fetch real-time data from liquid staking protocols (e.g., using APIs).
* **Gas Optimization:** Consider gas costs in the capital allocation strategy.
* **Security Audits:** If you were to build a real system, security audits would be essential.
* **Backtesting:** Backtest the staking strategy to evaluate its performance over time.
* **User Interface:** Develop a user interface for users to interact with the aggregator.
This improved example provides a much more solid foundation for building a more advanced AI-driven liquid staking aggregator. Remember that this is a simplified example; a real-world implementation would be significantly more complex.
