+## ✨ Key Features
+
+### 🎤 Voice-First Interaction
+- **Hold-to-speak** voice commands processed entirely on-device
+- Natural language understanding: *"Send 50 USDT to alice.sol"*
+- AI-generated voice responses via local TTS
+- Real-time waveform visualization during recording
+
+### 🧠 6-Package QVAC AI Integration
+- **LLM**: Llama 3.2 3B Instruct — parses intents, answers questions, validates transactions
+- **Embeddings**: Nomic Embed Text — powers semantic search (RAG) over your transaction history
+- **Speech-to-Text**: Whisper — converts voice to text offline
+- **Text-to-Speech**: Piper TTS — speaks confirmations and responses
+- **Translation**: Neural machine translation — use SolVox in any language
+- **OCR**: Extracts Solana addresses and amounts from images/QR codes
+
+### 💰 Non-Custodial Solana Wallet

+- **PIN + Biometric** authentication (Touch ID on macOS)
+- **Transaction limits** — per-tx max, daily volume, velocity limiting
+- **Address whitelisting** — restrict sends to approved addresses only
+- **AI anomaly detection** — flags unusual amounts, timing, and velocity
+- **Auto-lock** after 5 minutes of inactivity
+- **Zero key exposure** — private keys never cross the IPC boundary
+- **Content Security Policy** — blocks XSS and script injection
+- **Process isolation** — `contextIsolation: true`, `sandbox: true`, `nodeIntegration: false`
+
+### 🔍 RAG-Powered Transaction Intelligence
+- Semantic search over your transaction history: *"When did I last send to Bob?"*
+- Local vector store with cosine similarity search
+- Automatic transaction context enrichment for LLM responses
+- All indexing and search runs offline via `@qvac/embed-llamacpp`

+
+## 🚀 Quick Start
+
+### Prerequisites
+- **Node.js** ≥ 18
+- **npm** ≥ 9
+- ~3 GB disk space for AI models
+- Any GPU with Vulkan support (or CPU fallback)
+
+### 1. Clone & Install
+
+```bash
+git clone https://github.com/muthuk1/solvox.git
+cd solvox
+npm install
+```
+
+### 2. Download AI Models
+
+```bash
+chmod +x scripts/download-models.sh
+./scripts/download-models.sh
+```
+
+This downloads ~2.6 GB of models:
+| Model | Size | Purpose |
+|---|---|---|
+| Llama 3.2 3B Instruct (Q4_K_M GGUF) | ~2.0 GB | Chat, intent parsing |
+| Nomic Embed Text v1.5 (Q4_K_M GGUF) | ~260 MB | Semantic search / RAG |
+| Whisper Base English (GGML) | ~150 MB | Speech recognition |
+| Piper TTS Amy (ONNX) | ~75 MB | Voice synthesis |
+| Translation model (OPUS) | ~50 MB | Multilingual support |
+| PaddleOCR v4 (ONNX) | ~30 MB | Text extraction |
+
+### 3. Run in Development
+
+```bash
+npm run dev        # Starts Electron + Vite dev server
+npm start          # Runs built version
+```
+
+### 4. Build for Distribution
+
+```bash
+npm run build      # Build TypeScript + Vite
+npm run package    # Create installers (dmg/nsis/AppImage)
+```
+
+---
+
+## 🔒 Security Architecture
+
+### Key Protection
+
+```
+User PIN ──→ PBKDF2 (600K iterations, SHA-512)
+                │
+                ▼
+         AES-256-GCM encryption
+                │
+                ▼
+         Electron safeStorage (OS keychain)
+                │
+                ▼
+         Encrypted vault file (0600 permissions)
+```
+
+- **Private keys NEVER leave the main process** — the renderer only receives the public key and signed transaction bytes
+- **In-memory keypair is zeroed on lock** — `secretKey.fill(0)` for best-effort memory clearing
+- **5 failed PIN attempts → 15 minute lockout** — prevents brute force
+- **CSP headers block** `unsafe-eval`, `unsafe-inline` scripts, and external connections
+
+### Transaction Security
+
+| Feature | Description |
+|---|---|
+| **Amount limits** | Configurable per-transaction and daily volume caps |
+| **Velocity limiting** | Max N transactions per hour |
+| **Cooldown** | Configurable delay between transactions |
+| **Whitelist** | Optional — restrict sends to pre-approved addresses only |
+| **Anomaly detection** | AI flags: unusually large amounts (>5x average), odd-hour transactions, rapid sequences, volume spikes |
+| **Confirmation** | Every transaction requires explicit user confirmation |
+| **Audit trail** | Complete log of all transactions and anomaly events |
+
+### IPC Security
+
+```

+    │
+    │  contextBridge — allowlisted channels only
+    │  No require(), no Node.js, no filesystem access
+    │

+    │
+    │  Input validation on EVERY IPC handler
+    │  Address regex: /^[1-9A-HJ-NP-Za-km-z]{32,44}$/

+@qvac/translation-nmtcpp (→ Georgian)
+      │
+      ▼
+@qvac/tts-onnx (speak Georgian response)
+```
+
+### RAG System
+
+The local vector store indexes:
+- Transaction descriptions (amount, recipient, token, timestamp)
+- Contact names and addresses
+- User queries and AI responses
+
+Search uses cosine similarity on embeddings generated by `@qvac/embed-llamacpp`. No data ever leaves the device.

+## 🌍 Why Local AI Matters for Wallets
+
+Cloud-based AI wallets have a fundamental problem: **your financial data passes through someone else's servers.** Every transaction, every balance check, every voice command — all routed through centralized infrastructure that can:
+
+- **Log your data** — your financial history becomes training data
+- **Censor transactions** — refuse to process based on arbitrary rules
+- **Go offline** — if the server goes down, your wallet is useless
+- **Be compromised** — centralized servers are honeypots for attackers
+
+SolVox eliminates all of these risks. QVAC's Vulkan-based engine runs on **any GPU** — NVIDIA, AMD, Intel, even mobile GPUs — without requiring CUDA or cloud credentials. Your voice commands are transcribed locally, intents are parsed locally, and transaction confirmations are generated locally.
+
+**Your AI. Your wallet. Your device. Your rules.**

+# 🛡️ SolVox Security Model
+
+## Threat Model
+
+SolVox operates under the assumption that:
+1. The **renderer process is untrusted** — it could be compromised via XSS
+2. The **main process is the trust boundary** — all key operations happen here
+3. The **local filesystem is semi-trusted** — OS-level encryption protects at-rest data
+4. The **network is adversarial** — only Solana RPC calls leave the device
+
+## Security Controls
+
+### 1. Process Isolation
+
+| Control | Setting | Purpose |
+|---|---|---|
+| `contextIsolation` | `true` | Renderer cannot access Node.js globals |
+| `nodeIntegration` | `false` | No `require()` in renderer |
+| `sandbox` | `true` | OS-level process sandbox (Chromium) |
+| `webSecurity` | `true` | Same-origin policy enforced |
+| `allowRunningInsecureContent` | `false` | No HTTP content in HTTPS context |
+| `navigateOnDragDrop` | `false` | Prevents file drag-and-drop navigation |
+
+### 2. IPC Channel Allowlist
+
+The preload script exposes ONLY these namespaced channels via `contextBridge`:
+
+```
+wallet:create, wallet:import, wallet:getPublicKey, wallet:getBalance,
+wallet:sendSOL, wallet:sendUSDT, wallet:getHistory, wallet:isUnlocked,
+wallet:lock, wallet:exists
+
+auth:biometric, auth:unlock, auth:setPin, auth:biometricAvailable
+
+security:getSettings, security:updateSettings, security:addWhitelist,
+security:removeWhitelist, security:getWhitelist, security:getAnomalies

+```
+
+**No raw `ipcRenderer` is ever exposed.** The renderer cannot invoke arbitrary IPC channels.
+
+### 3. Key Storage
+
+```
+Mnemonic/Private Key
+    │
+    ▼
+PIN-based AES-256-GCM (PBKDF2, 600K iterations, SHA-512)
+    │
+    ▼
+Electron safeStorage (OS keychain: macOS Keychain / Windows DPAPI / Linux libsecret)
+    │
+    ▼
+File on disk (0600 permissions, owner-only)
+```
+
+The mnemonic is **double-encrypted**: first with the user's PIN (AES-256-GCM with PBKDF2-derived key), then with OS-level `safeStorage`. An attacker who obtains the vault file still needs:
+1. The user's OS login credentials (to decrypt safeStorage)
+2. The user's PIN (to decrypt the inner AES layer)
+
+### 4. In-Memory Key Handling
+
+- The `Keypair` object lives exclusively in the main process's `_sessionKeypair` variable
+- On lock: `secretKey.fill(0)` zeroes the key buffer (best-effort; V8 GC is non-deterministic)
+- Auto-lock triggers after 5 minutes of inactivity
+- Key material is NEVER sent over IPC — only the public key (base58 string) and signed transaction bytes
+
+### 5. Transaction Guards
+
+| Guard | Protection |
+|---|---|
+| **Input validation** | Regex-validated addresses, bounds-checked amounts |
+| **Per-tx limits** | Configurable maximum per transaction |
+| **Daily volume** | Cumulative daily spend limit |
+| **Velocity** | Max transactions per hour |
+| **Cooldown** | Minimum time between transactions |
+| **Whitelist** | Optional — only send to pre-approved addresses |
+| **Anomaly detection** | AI-powered pattern analysis (high amounts, odd hours, rapid sequences) |
+| **Confirmation** | Every transaction requires explicit user confirmation |
+
+### 6. Content Security Policy
+
+```
+default-src 'self';
+script-src 'self';
+style-src 'self' 'unsafe-inline';
+img-src 'self' data: https:;
+connect-src 'self' https://api.mainnet-beta.solana.com https://api.devnet.solana.com;
+object-src 'none';
+base-uri 'self';
+form-action 'self';
+frame-ancestors 'none';
+```
+
+- No `unsafe-eval` — prevents `eval()` and `new Function()` attacks
+- No external scripts — blocks CDN-based script injection
+- Limited connect-src — only Solana RPC endpoints allowed
+- No frames — prevents clickjacking
+
+### 7. Navigation Protection
+
+- All navigation to non-local URLs is blocked
+- New window creation is denied (`setWindowOpenHandler(() => ({ action: 'deny' }))`)
+- DevTools are disabled in production builds
+
+## Data Flow
+
+```
+Voice Input ──→ QVAC (local) ──→ Intent ──→ Main Process validates ──→ Wallet signs ──→ Solana RPC
+                                                    │
+                                                    ▼
+                                            TransactionGuard checks:
+                                            ├── Address format valid?
+                                            ├── Amount within limits?
+                                            ├── Daily volume OK?
+                                            ├── Velocity limit OK?
+                                            ├── Address whitelisted?
+                                            ├── Anomaly detected?
+                                            └── User confirmed?
+```
+
+**Only the signed transaction bytes leave the device** — via Solana RPC. All AI processing, intent parsing, and validation happen locally.
+
+## Known Limitations
+
+1. **V8 garbage collection** means `secretKey.fill(0)` doesn't guarantee the key is erased from all memory pages
+2. **Electron renderer** could theoretically be compromised via a 0-day in Chromium — contextIsolation + sandbox mitigate this
+3. **Transaction privacy** is limited by Solana's public blockchain — recipients and amounts are on-chain
+4. **PIN brute-force** is mitigated by PBKDF2 (600K iterations) + lockout, but a sufficiently weak PIN (e.g., `123456`) can still be guessed
+
+## Recommendations for Production
+
+- Use a hardware security module (HSM) or secure enclave for key storage
+- Implement Shamir's Secret Sharing for mnemonic backup
+- Add a dead man's switch (auto-transfer if inactive for N days)
+- Integrate with hardware wallets (Ledger/Trezor) for signing
+- Add transaction simulation (Solana `simulateTransaction`) before signing
