What this diagram shows

This flowchart depicts the high-level integration architecture of three primary services: blockchainService.ts, firebaseService.ts, and qrCodeService.ts. It details their internal dependencies such as Smart Contract ABIs, Web3 Provider, MetaMask Wallet for blockchain; Firestore Database and Authentication for Firebase; and QR Generation/Scanning for QR services.

When to use it

Use this diagram when designing a decentralized application (dApp) or a system that requires secure data storage, user authentication, and physical-digital interaction via QR codes, such as supply chain tracking or digital identity solutions.

How to adapt it for your project

This diagram can be adapted by replacing specific technologies (e.g., Ethereum with Solana, Firebase with AWS Amplify, different QR libraries). It can also be extended to include more services like payment gateways, analytics, or IoT integrations, showing how each service interacts with its components.
