<details>

<summary>How can BY strategies provide higher returns than other options?</summary>

The BY algorithm is programmed to analyze the supply rate functions across integrated protocols and total funds in the pool, and it's able to constantly rebalance capital across any number of protocols to **earn the highest interest rate possible** with very high precision.

<summary><strong>How is the BY APY calculated in each pool?</strong></summary>

The displayed APY is the aggregated interest rate of the APYs coming from multiple lending providers, depending on the allocated funds and the governance tokens from the underlying protocols.

</details>

<details>

<summary><strong>When a BY rebalance is triggered?</strong></summary>

Several factors can trigger a rebalance. Factors related to network conditions/congestion, and if a new allocation exceeds the previous one by a significant percentage. Hence, the timing is variable.

In general, a rebalance happens every 3 hours on Ethereum and hourly on Polygon.

<details>

<summary><strong>Can I add more funds if I already deposited assets?</strong></summary>

Yes, any user who has already deposited funds within one or more pools can add additional funds to the current deposited assets.&#x20;

Each addition of new funds always requires a confirmation and signature via smart contract, and therefore require to pay the related network fees.

</details>

<details>

<summary><strong>Are there any protocol fees related to BY?</strong></summary>

The BY strategies charge a performance fee on the yields generated when deposited funds are redeemed.&#x20;

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.idle.finance/products/best-yield/faqs.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
