# Sign a Transaction / Message

Tomo provides a smooth and secure experience when interacting with the dApp. Whenever the dApp creates a transaction according to your request, or you send/swap a token in the social wallet, it triggers Tomo's signing flow. You can look into the details of the transaction. If the transaction is in standard format, like a transfer token or function call, Tomo will parse the transaction so you can confirm whether the details are correct and the transaction fee.

After clicking the sign button, Tomo will trigger the second-factor authentication with your default MFA setting to ensure it's your operation. Then, sign the transaction and send it to the corresponding network. If the wallet has insufficient balance or the transaction is malformed, the procedure will fail with an error message.

## 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.tomo.inc/tomo-sdk/tomo-web-sdk/embedded-wallet-ui-component/sign-a-transaction-message.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.
