# Multiple providers

This section is relevant to you, if your dapp wants to support more than one NuFi SDK provider (Snap / NuFiConnect) or wants to use NuFiConnect with more blockchains. Note that currently only Cardano is being supported.

*The takeaway is that before accessing some provider, the last invocation of `initNufiDappCardanoSdk` has to be called with the settings matching this provider.*

### Example: Changing NuFi SDK providers

To showcase the usage please consider the below example:

* User clicks on "Metamask" icon in your dapp
* The dapp calls `initNufiDappCardanoSdk(nufiCoreSdk, 'snap')`
* Dapp can now access `window.cardano.nufiSnap`
* User is finished using the snap, disconnects and clicks on "NuFiConnect" social button
* The dapp calls `initNufiDappCardanoSdk(nufiCoreSdk, 'sso')`
* Dapp can now access `window.cardano.nufiSSO`
* Accessing `window.cardano.nufiSnap` will no longer work correctly!
* If you need to access `window.cardano.nufiSnap` again, you need to call `initNufiDappCardanoSdk(nufiCoreSdk, 'snap')` before that

## 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://nufi.gitbook.io/developer-docs/nuficonnect-single-sign-on-sdk-for-cardano-dapps/instructions/multipleproviders.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.
