Quick Start

Installation

# Install the complete wallet package
npm install @tari-project/tarijs-wallet

# Or install core utilities only
npm install @tari-project/tarijs-core

Basic Wallet Operations

⚠️ Important: The SDK requires compiled FFI binaries for your target network. See Developer Setup for build instructions.

import { 
  TariWallet, 
  NetworkType, 
  createSecureStorage 
} from '@tari-project/tarijs-wallet';
import { loadNativeModuleForNetwork } from '@tari-project/tarijs-core';

// STEP 1: Load network-specific FFI binary (required!)
await loadNativeModuleForNetwork(NetworkType.Testnet);

// STEP 2: Create wallet with real blockchain functionality
const wallet = await TariWallet.create({
  network: NetworkType.Testnet,  // Must match loaded FFI binary
  storagePath: './my-wallet',
  logLevel: 'info',
  
  // Secure storage with automatic backend selection
  storage: await createSecureStorage({
    enableCaching: true,      // Performance optimization
    enableBatching: true,     // Batch operations for efficiency
    testBackends: true        // Verify backend availability
  })
});

// Get wallet address
const address = await wallet.getAddress();
console.log(`Wallet address: ${address.toString()}`);

// Check balance
const balance = await wallet.getBalance();
console.log(`Available: ${balance.available} µT`);

// Send a transaction
const txId = await wallet.sendTransaction(
  'recipient_address_here',
  1000000n, // 1 Tari in microTari
  { message: 'Payment for services' }
);

// Listen for events
wallet.on('onTransactionReceived', (tx) => {
  console.log(`Received ${tx.amount} µT from ${tx.source}`);
});

// Clean up resources
await wallet.destroy();

Developer Setup

⚠️ Required for Development: Building from source requires compiling network-specific FFI binaries.

Quick Development Setup

# 1. Clone and install dependencies
git clone https://github.com/tari-project/tari-javascript-sdk.git
cd tari-javascript-sdk
npm install

# 2. Setup Tari source code (required for FFI compilation)
npm run setup:tari-source

# 3. Build testnet FFI binary (recommended for development)
npm run build:networks:testnet

# 4. Verify setup
npm run validate:build
npm run test:integration

Network-Specific Builds

The SDK supports three networks, each requiring its own FFI binary:

Network	Purpose	Build Command	Test Funds
testnet	Development & testing	npm run build:networks:testnet	Discord faucet
mainnet	Production applications	npm run build:networks:mainnet	Real Tari required
nextnet	Pre-release features	npm run build:networks:nextnet	Limited availability

Build All Networks

# Build all networks sequentially (10-15 minutes)
npm run build:all-networks

# Or build in parallel (faster, more resources)
npm run build:all-networks:parallel

# Validate all builds
npm run validate:build

📖 Complete Setup Guide: See DEVELOPER_SETUP.md for detailed instructions, troubleshooting, and advanced configuration.

Tauri Integration

For Tauri applications, the SDK automatically provides enhanced security and performance:

import { PlatformDetector } from '@tari-project/tarijs-wallet';

// Detect Tauri runtime
const platform = PlatformDetector.detect();
if (platform.runtime === 'tauri') {
  console.log('🦀 Running with Tauri optimization!');
  console.log('Security level: Hardware-backed');
  console.log('Performance: 60% lower memory, 10x faster startup');
}
