Installation & usage of React Native SDK

Prerequisites

• Required development environment
• My Cloud Wallet App installed
  • iOS: https://apps.apple.com/us/app/my-cloud-wallet/id6473984457
  • Android: https://play.google.com/store/apps/details?id=com.waxcloudwalletmobile
• Backend requirements (for WebSocket mode)

Getting Started

Install the SDK package using npm:

npm install @waxio/sdk-react-native

or yarn

yarn add @waxio/sdk-react-native

Setup Instructions

1. Configure Deep Linking

First, set up your application to handle deep links across different platforms. Follow the React Navigation deep linking documentation.

2. Configure Platform-Specific Settings

iOS Configuration Add MyCloudWallet to LSApplicationQueriesSchemes in your Info.plist:

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>mycloudwallet</string>
</array>

Android Configuration Add the necessary query intent to your AndroidManifest.xml:

<queries>
  <intent>
    <action android:name="android.intent.action.VIEW" />
    <data android:scheme="mycloudwallet" android:host="*" />
  </intent>
</queries>

3. Implement the Provider

Wrap your application with the WaxDeeplinkProvider:

import { WaxDeeplinkProvider } from "@waxio/sdk-react-native";

const getSingleUseToken = async () => {
  try {
    // Make API call to your auth endpoint to get a token
    const response = await fetch('https://your-auth-endpoint.com/token');
    const data = await response.json();
    return data.token;
  } catch (error) {
    console.error('Failed to get single use token:', error);
    throw error;
  }
};

export default function App() {
  return (
    <WaxDeeplinkProvider
      opts={{ pollingInterval: 2000 }}
      metadata={{
        name: "YourAppName",
        origin: "yourappscheme",
        description: "Description of your application",
        scheme: "yourappscheme",
        icon: "https://yourapp.com/icon.png",
      }}
      getSingleUseToken={getSingleUseToken}
      activationEndpoint="https://your-activation-endpoint.com"
      relayEndpoint="https://queue-relay.mycloudwallet.com/graphql"
      relayRegion="us-east-2"
    >
      {/* Your app components */}
    </WaxDeeplinkProvider>
  );
}

Provider Configuration Parameters

Parameter	Type	Description
opts	Object	Configuration options like polling interval
metadata	Object	Information about your application
getSingleUseToken	Function	Function to retrieve authentication token
activationEndpoint	String	Endpoint for wallet activation
relayEndpoint	String	Endpoint for transaction relay
relayRegion	String	Region for the relay service

Using the SDK

Connecting to WAX Wallet

Use the useWaxSDK hook in your components to interact with the WAX blockchain:

...
import { useWaxSDK } from "@waxio/sdk-react-native";
...
export default function YourComponent() {
  const {
    connect,
    directConnect,
    canDirectConnect,
    user,
    transact,
    directTransact,
    disconnect,
    getQRCode,
  } = useWaxSDK();

  return (
    <View>
      // Your applicaton is here
    </View>
  );
}

SDK Core Functions

Function	Description
connect()	Initiates connection to the WAX wallet in a different device
directConnect()	Initiates connection to the WAX wallet on the same device
disconnect()	Terminates the connection with the WAX wallet
transact(actions)	Sends transaction to the blockchain via different devices
directTransaction(actions)	Sends transaction to the blockchain to the wallet app on the same device
user	Object containing user information when connected

Implementation Steps Summary

1. Install the SDK package
2. Configure deep linking for your application
3. Add necessary platform-specific configurations (Info.plist and AndroidManifest.xml)
4. Implement the WaxDeeplinkProvider in your app
5. Use the useWaxSDK hook in your components to connect and transact with the WAX blockchain

Troubleshooting Tips

1. Ensure you're using React Native v0.71.4 or higher to avoid performance issues on Android
2. Verify that deep linking is properly configured
3. Check that the app scheme is correctly set up in both your provider and platform configurations
4. Confirm that your endpoints for activation and relay are accessible and working correctly
