# Delta-Neutral Stability
### **1. What is Delta?**
Delta is a fundamental concept in financial derivatives, representing the rate of change of an option's price relative to the price of its underlying asset. For example, a delta of 0.5 means that if the underlying asset's price changes by $1, the option's price changes by $0.50. Delta is widely used in hedging strategies to manage risk effectively. Learn more about delta in this [Investopedia article](https://www.investopedia.com/terms/d/delta.asp).

### **2. Delta-Neutral Hedging in** USDu
USDu employs a basket of **delta-neutral strategies** to stabilize its collateral base and ensure peg stability. This means the protocol maintains a balance between the value of its collateral assets (e.g., SOL, ETH) and the futures positions held to hedge against price fluctuations. By offsetting potential gains or losses from underlying assets, delta-neutral hedging allows USDu to maintain a consistent 1:1 peg with 1 USD.

### **3. Why Delta-Neutral?**
1. **Removed market exposure**: by using hedging strategies, USDu ensures that collateral value remains stable even during market fluctuations.
2. **Capital Efficiency**: unlike traditional CDP stablecoins, USDu's basket of delta-neutral strategies reduces the amount of locked collateral, enabling scalability without sacrificing security.
3. **Scalability**: with access to both decentralized (DEX) and centralized (CEX) liquidity, USDu can scale into billions without dependence on traditional financial systems or real-world assets.
***
### **4. How it Works**
1. **Collateral Management**: USDu primarily uses SOL as collateral, along with BTC and ETH, to maintain a diverse asset base.
2. **Hedging Mechanism**: The protocol utilizes futures contracts on highly liquid platforms to neutralize price volatility of the collateral assets.
3. **Stability Enforcement**: Smart contracts monitor and adjust positions dynamically, ensuring consistent stability for USDu holders.

```
GET https://docs.unitas.so/solution-overview/delta-neutral-stability.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
