All rates should be validated with the 3rd party protocol as there may be mistranslations of the rates of return provided by the 3rd party. Additionally, Harvest may "boost" the APY% of a given pool by adding `$FARM` reward emissions to the overall earnings. The breakdown of rewards is specified in each pool and `$FARM` emissions are published weekly [here](https://medium.com/harvest-finance).\ \ \ **Important:** The stated AP\[\[R]/\[Y]] (the 'Rate') is denominated in terms of \[RELEVANT TOKEN], not USD or other fiat currency. The Rate is a forward-looking projection based on good faith belief of how to reasonably project results over the relevant period, but such belief is subject to numerous assumptions, risks and uncertainties (including smart contract security risks and third-party actions) which could result in a materially different (lower or higher) token-denominated AP\[\[R]/\[Y]]. The Rate is not a promise, guarantee or undertaking on the part of any person or group of persons, but depends entirely on the results of the operation of smart contracts and other autonomous systems (including third-party systems) and how third parties interact with those systems after the time of your converting. Even if the Rate is achieved as projected, you may still suffer a financial loss in fiat-denominated terms if the fiat-denominated value of the relevant tokens (your converted tokens and any tokens allocated or distributed to you pursuant to the Rate) declines during the farming period. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.harvest.finance/general-info/what-do-we-do/variable-rates-of-return-apy.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. 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.
