## Description

<figure><img src="/files/GqOHdI4onL0HfgyrBUNY" alt=""><figcaption></figcaption></figure>

This vault optimizes looped wstETH returns by constantly scanning for the lowest ETH borrow rates  across Aave, Compound, & Morpho wstETH:ETH markets.

By repeatedly borrowing WETH against wstETH when the borrow rates are low, the vault is able to multiply the interest differentials (i.e. yield carry). A wstETH:ETH Long position is created with a 2.5% liquidation buffer on the identified market.

Positions are migrated between markets with minimal price impact as only the portion of liquidity relating to the differing max loan-to-value ratios are swapped.

Any earned rewardsa are automatically compounded for more wstETH.

\+ wstETH liquid staking yields

\+ COMP borrow rewards

\- ETH borrow interest

{% tab title="Main strategy" %}

1. Flash loan $WETH up to 16.1x (dependent on market)
2. Swap WETH → wstETH
3. Lend all $wstETH on market with lowest $ETH borrow
4. Borrow $ETH to cover flash loan
   {% endtab %}

{% tab title="Exit Strategy" %}

1. Flash loan $ETH
2. Repay $ETH debt&#x20;
3. Withdraw $wstETH collateral
4. Swap $wstETH → $ETH
   {% endtab %}

{% tab title="Refinance" %}

1. Flash loan $ETH
2. Repay all $ETH debt on current market
3. Withdraw all $wstETH on current market
4. Lend all $wstETH on target market
5. Borrow $ETH to repay flash loan
   {% endtab %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.factor.fi/factor-discover/factor-operated-strategies/yield-type-strategies/base-chainid-8453/wsteth-eth-loop-optimizer-aave-compound-morpho.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.
