SpruceID Wallet SDK for React Native

Maturity Disclaimer

In its current version, Wallet SDK has not yet undergone a formal security audit to desired levels of confidence for suitable use in production systems. This implementation is currently suitable for exploratory work and experimentation only. We welcome feedback on the usability, architecture, and security of this implementation and are committed to a conducting a formal audit with a reputable security firm before the v1.0 release.

Installation

npm install @spruceid/react-native-wallet-sdk

iOS

Add to the app's info.plist

	<key>NSBluetoothAlwaysUsageDescription</key>
	<string>Secure transmission of mobile DL/ID data</string>

Android

Add to the AndroidManifest.xml

  <uses-permission android:name="android.permission.BLUETOOTH" />
  <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
  <uses-permission android:name="android.permission.BLUETOOTH_ADVERTISE" />
  <uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
  <uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

In addition to the manifest, on newer Android versions your applications will also need to trigger a dialogue prompt. You can refer to this documentation for more information

await PermissionsAndroid.requestMultiple([
  'android.permission.ACCESS_FINE_LOCATION',
  'android.permission.BLUETOOTH_CONNECT',
  'android.permission.BLUETOOTH_SCAN',
  'android.permission.BLUETOOTH_ADVERTISE',
]);

Usage

import { createMdocFromCbor } from '@spruceid/react-native-wallet-sdk';

// ...

const mdoc = await createMdocFromCbor(mdocCborBase64);

Architecture

Our Wallet SDKs use shared code, with most of the logic being written once in Rust, and when not possible, native APIs (e.g. Bluetooth, OS Keychain) are called in native SDKs.
