DAB Connect: Integration Layer for Web2 and Game Environments #

Overview
DAB Connect is the middleware for the Decentralized Authentication Bridge (DAB), providing Web2 and game development environments with modular tools to implement blockchain-based identity and authentication. It abstracts the complexities of direct blockchain interactions, enabling applications to verify wallet-based identity, manage token-gated access, and fetch authenticated blockchain data without requiring dedicated Web3 infrastructure.

Functional Scope #

• Wallet-Based Authentication: Enables login and session persistence using blockchain wallets.
• Token-Gated Access Control: Grants or restricts access to resources based on verified token holdings.
• Data Interfacing: Provides secure access to authenticated wallet-linked data.

Architecture and Integration Modules #

1. Connect SDK (QR Code Auth)

• Lightweight SDK for integrating QR-based wallet login into Web2 environments (web/mobile).
• Securely generates authentication sessions with cryptographic verification.

2. Unreal Engine Plugin

• Integrates wallet login, blockchain identity resolution, and NFT utility for games built in Unreal Engine.
• Exposes blueprint and C++ interfaces for session handling and token access.

3. Unity Plugin

• Adds authentication, NFT validation, and token-gated logic to Unity-based environments.
• Supports in-game asset ownership, token-based interactivity, and blockchain session persistence.

Security Model #

• Nonce-Based Verification: Ensures cryptographic integrity for login requests.
• Stateless Session Architecture: Reduces server-side dependencies and enhances horizontal scalability.
• Role-Based Access Support (optional): Enables granular policy definition via smart contracts.

Supported Use Cases #

• Web2 portals requiring wallet-based login without full blockchain stack integration.
• Game engines needing authenticated access to token ownership or NFT metadata.
• Applications implementing dynamic access control via token holdings.

Deployment Targets #

• Web platforms (React, Vue, etc.)
• Mobile frameworks (React Native, native Android/iOS)
• Game engines (Unity 2021+, Unreal Engine 5.x)

Summary #

DAB Connect enables Web2-native systems and game environments to authenticate blockchain identities and enforce token-based access without the need to manage full-node infrastructure or custom smart contracts. Its modular SDKs and engine-specific plugins provide developers with the tooling to integrate blockchain-native capabilities into existing software stacks efficiently.
