Overview SolCipher VR is an immersive, privacy-first decentralized application (dApp) for Meta Quest devices that revolutionizes secure document sharing between Solana wallets in virtual reality. It combines client-side AES-256-GCM encryption, decentralized IPFS storage, and Solana smart contracts for access control, all enhanced with intuitive hand interactions and mixed reality passthrough for a seamless spatial computing experience. Innovation: The first privacy-first secure document sharing dApp in VR using Solana blockchain and IPFS, featuring natural hand interactions and passthrough mixed reality. Competition Alignment:

Track: Lifestyle Categories: Best Implementation of Hand Interactions + Best Experience Built with Spatial SDK

Problem Solved Traditional file sharing requires leaving VR, breaking immersion. SolCipher VR enables users to securely share sensitive documents without removing their headset, using natural hand gestures and spatial UI. Core Features

VR-Native Document Sharing Upload and share encrypted documents entirely within VR Natural hand tracking for file selection and manipulation Spatial UI floating panels for intuitive interaction Voice commands for accessibility

Mixed Reality Integration (Passthrough Camera) View physical documents through passthrough camera Scan QR codes from real-world documents using camera Overlay document metadata in physical space Context-aware AI to detect document types

Hand Interactions (No Controllers Required) Pinch gestures to select files Hand rays for pointing at UI elements Two-handed gestures for document preview/zoom Microgestures for quick actions (revoke, share, decrypt) Direct touch UI for buttons and inputs

Blockchain Integration in VR Solana wallet connection via QR code or deeplink Transaction signing with hand gesture confirmation Visual blockchain transaction feedback Real-time on-chain access control visualization

Immersive 3D Document Visualization 3D holographic document previews Spatial document gallery (floating documents around user) Recipient visualization (avatar representations) Access status indicators with particle effects

Social VR Features Multi-user spaces for collaborative document review Avatar system showing online contacts Real-time document sharing notifications Voice chat for secure communication

Architecture Workflow (VR-Optimized)

User enters VR environment ↓ Connect Solana wallet via QR code scan (passthrough camera) ↓ Navigate to upload zone with hand tracking ↓ Pinch gesture to open file browser OR Enable passthrough to capture physical document with camera ↓ Select recipient from spatial contact list ↓ Hand gesture to confirm encryption ↓ Request wallet signature (visualized in 3D space) ↓ Derive encryption key from signature ↓ Encrypt document with visual progress indicator ↓ Upload to IPFS with animated upload beam ↓ Create on-chain record with particle effect confirmation ↓ Document appears in recipient's VR space with notification

Recipient Workflow

Notification appears as floating hologram ↓ Pinch notification to open document preview ↓ Two-handed gesture to expand preview ↓ Verify on-chain access (visual chain animation) ↓ Request signature to decrypt (hand confirmation gesture) ↓ Document decrypts with particle dissolve effect ↓ View in immersive 3D space or download to device
