# Wallet SDK

The [Wallet SDK](https://github.com/docknetwork/wallet-sdk) enables you to build an identity wallet inside your app and allows your users to receive, store, and manage verifiable credentials.

To use the wallet-sdk, all you need to do is wrap your app in a `WalletSDKProvider` and start building your wallet.

The Truvera Mobile SDK supports:

* Devices that have Android 8.1 or higher and iOS 11 or higher.
* Minimum supported version of Node.js is 20.2.0

## Installation

```js
npm install @docknetwork/wallet-sdk-core
npm install @docknetwork/wallet-sdk-react-native

```

**There are some scripts and additional dependencies required.** Please check our [examples](https://github.com/docknetwork/wallet-sdk/tree/master/examples) folder for detailed steps.

## React Native example

The following example will create a wallet and allow the user to add credentials to it, displaying the count of documents added to the wallet. Notice that all documents are accessible through the `documents` object.

```js
import {Box, Button, NativeBaseProvider, Text} from 'native-base';
import React, {useEffect} from 'react';
import {
  WalletSDKProvider,
  useWallet,
} from '@docknetwork/wallet-sdk-react-native/lib';

const WalletDetails = function () {
  const {wallet, status, documents} = useWallet();

  return (
    <Box>
      <Text>Wallet status: {status}</Text>
      <Text>Wallet docs: {documents.length}</Text>
      <Button onPress={() => wallet.addDocument({
        name: 'my credential',
        type: 'VerifiableCredential',
      })}>
        <Text>Add Credential</Text>
      </Button>
    </Box>
  );
};

const App = () => {
  return (
    <NativeBaseProvider>
      <WalletSDKProvider>
        <Box p={8}>
          <Text>Dock Wallet SDK Demo</Text>
          <Text>Press on `add credential` button to create a new credential</Text>
        </Box>
        <WalletDetails />
      </WalletSDKProvider>
    </NativeBaseProvider>
  );
};

export default App;

```

## 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.truvera.io/credential-wallet/wallet-sdk.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.
