Overview

This guide will walk you through the steps to setup a new react native expo project with Google sso and auth proxy.

Goals:

• Setup Google sso in React Native Expo
• Setup auth proxy and duo server
• Setup silent-shard-sdk in React Native Expo
• Able to perform MPC operations with silent-shard-sdk

Steps to be followed in order:

1. Setup Google sso in React Native Expo
2. Get serviceAccountKey.json from firebase
3. Setup auth proxy and duo server
4. Install silent-shard-sdk in React Native Expo
5. Setup silent-shard-sdk in React Native Expo

Why Use Auth Proxy?

• Security: Adds an authentication layer to protect access to MPC operations
• Flexible Authentication: Currently supports Firebase Auth with extensible design for other providers
• WebSocket & HTTP Support: Handles both communication patterns seamlessly

Architecture

The Auth Proxy:

1. Authenticates incoming requests using Firebase ID tokens
2. Manages user-to-wallet mappings for access control
3. Establishes Two-way communication between the Duo Server and Client
