Multi-API Implementation Examples

Overview

The DragonFire ecosystem consists of multiple specialized APIs and SDKs that can be combined to create powerful applications. These examples demonstrate how to integrate multiple components to leverage their combined capabilities through phi-resonant pathways.

Wallet + RWT Integration

This example demonstrates how to implement a secure financial application by combining the Dragon Wallets SDK with RWT authentication:

// Install required SDKs
// npm install @dragonfire/client @dragonfire/wallet-client @dragonfire/rwt-client

import { DragonFireClient } from '@dragonfire/client';
import { WalletClient } from '@dragonfire/wallet-client';

    });
    
    // Create specialized clients
    this.walletClient = null;
    this.rwtClient = null;
  }

    try {
      // Initialize core client
      await this.dragonfire.initialize();

        autoBackup: true
      });
      console.log('Wallet client initialized');
      
      // Initialize RWT client for secure communications
      this.rwtClient = new RWTClient(this.dragonfire, {

// Authentication with RWT security

      this.rwtClient.setupTokenRotation({
        token: token,
        interval: 300000, // 5 minutes
        pattern: 'phi', // Phi-resonant rotation pattern
        callback: (newToken) => {
          // Update token across all services

// Real-time balance and transaction updates

async function setupRealtimeUpdates(accountId) {
