Here are some of the errors you might run into! ### Slippage Slippage refers to the difference between the expected price of a trade when an order is placed and the actual price at which it is executed, caused by market fluctuations during transaction processing. On Moonshot, you can adjust your slippage between 0.5% and 20%. If your slippage is set too low and the token is volatile, you may receive an error message indicating that your slippage is too low. You can change your slippage using the button in the top-left corner of the buy/sell screen. ### An error occurred in the cloud You may see this error pop up during an unsuccessful trade. This could mean one of two things: 1. Some of our Internal services may be down. 2. And in some rare cases, an unknown error occurred during the transaction process. ### A problem occurred on the blockchain This uncommon error can result from a few different issues. The two main reasons are: 1. The transaction was invalid before submission. 2. There was a smart contract error during confirmation. #### If you encounter any of these errors at any time, please reach out to our support team! --- # 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://support.moonshot.com/trade/buy-and-sell/troubleshooting.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.
