# stx\_signTransaction

Requests the connected wallet to sign a pre-built Stacks transaction. Optionally broadcasts the transaction after signing.

***

### Usage

```ts
import { request } from '@stacks/connect';

const result = await request('stx_signTransaction', {
  transaction: '0x0000...raw-transaction-hex',
  broadcast: true,
});

console.log('Transaction ID:', result.txid);
console.log('Signed transaction:', result.transaction);
```

```ts
import { request } from '@stacks/connect';

// Sign without broadcasting (e.g. for sponsored transactions)
const result = await request('stx_signTransaction', {
  transaction: '0x0000...raw-transaction-hex',
  broadcast: false,
});

// The signed raw transaction is returned for manual broadcasting
console.log('Signed transaction hex:', result.transaction);
```

#### Notes

* The `transaction` parameter should be a hex-encoded serialized Stacks transaction.
* This method is useful when you need to construct the transaction yourself (e.g. using `@stacks/transactions`) and only need the wallet for signing.
* When `broadcast` is `false`, the signed transaction hex is returned without broadcasting. This is useful for sponsored transaction workflows.

## 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.stacks.co/reference/stacks.js/stacks-connect/methods/stx_signtransaction.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.
