Introduction

Welcome to the TUWA SDK documentation — the official server-side SDK for the Quasar Cloud, featuring built-in React authentication bridges.

What is Quasar SDK?

@tuwaio/quasar-sdk is a type-safe Node.js & Edge SDK for interacting with the TUWA Quasar Cloud API. It provides two main ways to interact with the platform:

  1. Quasar Client: A stateful, server-side client for high-level operations like Pulsar transaction syncing.
  2. Utils: A set of stateless, functional utilities for signature verification and security (ideal for both server and browser).

Key Features

  • 🔐 Iron Dome Protocol — every request is authenticated via secret key headers
  • 🛡️ QuasarAuthBridge — built-in React component for unified EVM & Solana authentication
  • 📦 Dual module format — ships as ESM and CJS
  • 🧩 Modular architecture — isolated modules for Pulsar (Transactions) and Utils (Security)
  • 🔒 Server-side only — your secret keys never leak to the browser
  • 📖 Auto-generated API reference — TypeDoc annotations powering this docs site

Quick Start (Core & Utils)

import { Quasar, utils } from '@tuwaio/quasar-sdk';
 
// Initialize the client
const quasar = new Quasar({ secretKey: 'sk_live_...' });
 
// Use domain modules
await quasar.pulsar.syncCreate(transaction);
 
// Or use stateless utilities directly
const isValid = await utils.verifyMiniSession(params);

Quick Start (React)

import { QuasarAuthBridge } from '@tuwaio/quasar-sdk/react';
 
// Mount within your SatelliteConnectProvider tree to handle signatures
<QuasarAuthBridge
  activeConnection={activeConnection}
  store={store}
  wagmiConfig={config}
  session={miniSession}
  setSession={setMiniSession}
/>

Installation

pnpm add @tuwaio/quasar-sdk
