# E-Mode (Efficiency Mode)

E-Mode, or Efficiency Mode, is a feature designed for correlated assets — enabling users to borrow with a higher Loan-to-Value (LTV) while maintaining safe risk parameters.\
This unlocks more capital efficiency for looping strategies and leveraged yield farming.

***

### **How E-Mode Works**

* **Correlated Assets:** E-Mode applies to assets that are highly correlated (e.g. mBTC/RBTC, stables).
* **Higher LTV:** Max LTV is raised (e.g. 70% → 85%) so users can borrow more against their collateral.
* **Lower Liquidation Risk:** Liquidation thresholds (LLTV) are slightly increased, but still maintain a safety buffer.
* **Use Case:** Ideal for looping, stablecoin farming, or delta-neutral strategies where the collateral and borrow asset prices move together.
