# TokenizedStrategy

The `TokenizedStrategy` contract serves as a proxy-style implementation that centralizes logic, storage, and management for strategies inheriting from `BaseStrategy`. It facilitates the creation of ERC4626 compliant vaults by handling interactions and state transitions through delegated calls to this contract.

### **Contract Storage**

* **`StrategyData`**: This struct consolidates all storage variables needed for a strategy, optimizing for gas efficiency by reducing the frequency of storage slot loading during function execution. Key elements include:
  * **`initialDomainSeparator` and `initialChainId`**: Utilized for EIP-712 compliance across different chains.
  * **`totalSupply`, `totalIdle`, and `totalDebt`**: Track the total shares issued, the idle assets, and the assets actively deployed, respectively.
  * **`profitUnlockingRate` and `fullProfitUnlockDate`**: Manage the unlocking of profit over time.
  * **`management`, `keeper`, `emergencyAdmin`**: Addresses responsible for strategy management, routine maintenance, and emergency interventions.

### **Core Functionalities**

* **Initialization and Strategy Setup**: On the deployment of a new strategy, essential parameters like asset type, strategy name, and roles are established.
* **Asset Management**: Functions to deploy funds (`deployFunds`), free funds (`freeFunds`), and report the strategy's performance (`report`) encapsulate core investment strategy operations.
* **Fee Management**: The contract facilitates setting and adjusting performance fees, which are calculated on the profits generated by the strategy.

### **Access Control Modifiers**

* **`onlyManagement`**: Ensures that only the designated management address can perform certain administrative tasks.
* **`onlyKeepers`**: Restricts sensitive operations such as reporting to either the designated keeper or management addresses.
* **`onlyEmergencyAuthorized`**: Allows for emergency actions, such as strategy shutdown, to be executed by authorized emergency administrators.

### **Events**

* **Management Events**: Such as `UpdateManagement`, signal changes in management roles or parameters.
* **Operational Events**: Including `Deposit` and `Withdraw`, provide transactional transparency for assets moving in and out of the strategy.
* **Performance Reporting**: The `Reported` event logs the outcomes of performance reports, detailing profits, losses, and fees.

### **Strategy Interaction Functions**

* **`deposit`/`mint`**: For adding assets to the strategy in exchange for shares.
* **`withdraw`/`redeem`**: For removing assets from the strategy, optionally handling losses within specified bounds.
* **`shutdownStrategy`/`emergencyWithdraw`**: For halting new investments and managing assets in response to adverse conditions.

### **Configuration and Maintenance**

* **`setPerformanceFee`**, **`setKeeper`**, **`setEmergencyAdmin`**: Functions to adjust operational parameters and roles to respond to evolving strategy needs or external conditions.
* **`shutdownStrategy`**: A critical function used to cease all investment activities, allowing the strategy to only handle withdrawals and necessary maintenance.

### **Utility and Helper Functions**

* **`convertToShares`/`convertToAssets`**: Convert between the underlying asset and shares based on the current state of the strategy, aiding in calculations for deposits and withdrawals.
* **`_updateBalances`**: Ensures internal accounting reflects the actual state of assets within the strategy, crucial after any interaction that alters the balance of deployed or idle assets.
