# Aggregator vs Optimizer

> Understanding the two engines behind DeFi efficiency — and how CrediX merges them.

***

### Aggregator: The Router

An **aggregator** acts like a GPS for your assets.

It doesn’t hold your funds, but it **guides them** to where they’ll earn or cost the least — based on current protocol data.

###  **What It Does:**

* Finds the **best lending yield** or **lowest borrowing rate**
* Routes assets to the most optimal money market (e.g. Aave, Compound, Morpho)
* Avoids manual comparison across platforms

***

### Optimizer: The Strategist

An **optimizer** is more than a GPS — it’s a **smart autopilot** that dynamically adapts.

It not only routes, but also **manages, rebalances, and fine-tunes** your positions based on changing market conditions.

### **What It Does:**

* Monitors yield/borrow rates continuously
* **Auto-rebalances** when better opportunities appear
* Adapts to risk, volatility, protocol liquidity, and gas cost
* Can **implement strategies** (e.g. target yield %, minimum LTV)

### **Key Value:**

* **Reduces user effort**
* **Improves long-term performance**
* Responds in real-time to **market shifts**
