# NDK (Nostr Development Kit) Documentation This section contains technical documentation specific to the Nostr Development Kit (NDK) implementation in the POWR app. ## Key Documents - [Comprehensive Guide](./comprehensive_guide.md) - Complete reference for NDK implementation - [Subscription Analysis](./subscription_analysis.md) - Analysis of subscription patterns and solutions - [Encoding and Decoding](./encoding_decoding.md) - NIP-19 encoding and decoding processes ## Key NDK Concepts NDK is the primary library we use for Nostr protocol integration. It provides: - Connection and relay management - Event creation, signing, and publishing - Subscription management for receiving events - User management and profile handling - NIP-19 encoding and decoding utilities ## Implementation in POWR Our implementation of NDK follows these key principles: 1. Singleton state management via Zustand store 2. Proper subscription lifecycle management 3. Centralized relay configuration 4. Clear authentication flow 5. Simplified implementation for MVP needs ## Related Documentation - [Social Implementation](../../features/social/architecture.md) - How NDK is used in social features - [Authentication Design](../../architecture/state_management.md) - Authentication architecture **Last Updated:** 2025-03-25
