Why is my TVL figure going down? Am I losing money?** Your TVL (Total Value Locked) within Yield Yak is represented in USD and the price is obtained from CoinGecko’s price feed. The TVL is calculated by taking the farmers underlying assets in the farm and converting to the current price in USD. This means that if the price of the underlying assets fluctuates against the US Dollar then the value of your TVL will fluctuate also. Remember, however, that the auto-compounding is still adding LP tokens to your share of the farm. So, whilst your TVL represented in USD may have decreased in value, you are still increasing your LP tokens and getting the benefit of Yield Yak’s auto-compounding. ## Smart Contract Risk Yield Yak interacts with many external smart contracts. Yield Yak users take smart contract risk on Yield Yak contracts themselves, plus any external contracts Yield Yak interacts with. Deposits for each Yield Yak farm are isolated, meaning that assets held in "risky" farms cannot affect assets held in "safe" farms. --- # 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.yieldyak.com/for-farmers/risks/underlying.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.
