# High Efficiency Mode (E-mode)

### Overview

The High Efficiency Mode (E-mode) is designed to maximize capital efficiency by allowing users to leverage assets with correlated prices as collateral. This feature is particularly beneficial when dealing with assets like stablecoins, which maintain a consistent value relative to a specific reference, such as the USD.

### E-mode Asset Categories

Yei Finance supports two primary asset categories under E-mode:

1. **Stablecoins**: Examples include USDC and USDT, which are pegged to the USD and exhibit correlated price movements. Utilizing stablecoin E-mode, users can supply stablecoins and enjoy higher collateralization power when borrowing other stablecoins.
2. **SEI-related Assets**: This category includes assets such as WSEI and SEI. In SEI E-mode, users can supply these assets and benefit from a higher borrowing Loan-to-Value (LTV) ratio of up to 75%, thereby enhancing borrowing capacity.

### Borrowing Rules in E-mode

* **Category Restriction**: Only assets within the same category can be borrowed in E-mode. For instance, if a user supplies stablecoins in E-mode, they can only borrow other stablecoins.
* **Collateral Usage**: E-mode does not restrict the usage of other assets as collateral. Assets outside of the E-mode category can still be supplied as collateral, adhering to normal LTV and liquidation parameters.

### **How to Enter E-mode**

1. **Enable E-mode:** From the dashboard, find “Your borrows” and click “Enable E-mode.”

### How to Switch Asset Category Under E-mode

1. **Switch E-mode Category**: Select the E-mode icon and choose "Switch E-mode Category" to switch between SEI-related E-mode and Stablecoin E-mode.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.yei.finance/products/yeilend/high-efficiency-mode-e-mode.md?ask=<question>&goal=<endgoal>
```

`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.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
