# Turnkey signer

[Turnkey](https://www.turnkey.com/) is a key infrastructure provider with a powerful developer API and a robust security policy engine, enabling secure and flexible key management for blockchain applications.

#### **Setup**

To use **Turnkey** with **SDK Core**, first create an application that integrates with Turnkey.

* Refer to the [Turnkey documentation site](https://docs.turnkey.com/) for instructions on setting up an application with the Turnkey.
* For a quick start, Turnkey provides examples, available [here](https://docs.turnkey.com/getting-started/examples).

## Integration

After following the Turnkey documentation, you will have access to a `TurnkeyClient` object as shown below that you can pass as an owner to `createSafeSmartAccount`:

```typescript
import { TurnkeyClient } from "@turnkey/http"
import { createAccount } from "@turnkey/viem"


// Param options here will be specific to your project.  See the Turnkey docs for more info.
const turnkeyClient = new TurnkeyClient({ baseUrl: "" }, stamper)
 
const turnkeySigner = await createAccount({
	client: turnkeyClient,
	organizationId: subOrganizationId, // Your subOrganization id
	signWith: signWith, // Your suborganization `signWith` param.
})
  
```

## 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.cometh.io/sdk-core/signers-auth-providers/turnkey-signer.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.
