> Blockchain-based encrypted file storage with conditional access triggers for long-term file continuity and conditional sharing.

## What Vaulternal Does
- Client-side AES-256-GCM encryption (files encrypted in browser before upload)
- Decentralized storage via blockchain networks (Arweave, IPFS, Polygon)
- Conditional access triggers (time-based, inactivity, gatekeeper verification, manual, blockchain events)
- Multi-recipient encrypted sharing with per-recipient keys
- Long-term continuity planning with grace periods and verification
- Standard storage option for faster access (same client-side encryption)

## Pricing
- Free: 50MB storage, 1 trigger (time-based only)
- Starter ($8.33/mo billed annually): Unlimited storage, 250MB/month upload, 5 triggers
- Pro ($15/mo billed annually): Unlimited storage, 500MB/month upload, 10 triggers

## Technical Architecture
- React 19 + Next.js frontend with server-side rendering
- Client-side cryptography (AES-256-GCM symmetric + secp256k1-ECIES asymmetric)
- All encryption performed in browser Web Workers
- Zero-knowledge architecture: encryption keys derived from user-held recovery phrase
- 3 language support (en, es, ru) with 5 more coming soon (fr, de, pt, ja, zh)

## Trigger Categories
- Inactivity detection (wallet, app login, email, SMS, push)
- Time-based (absolute date, relative time)
- Gatekeeper verification (trusted contacts)
- Manual activation by owner
- Blockchain events (token balance, wallet activity, token price)
