+# Tauri + WASM Integration Fix
+
+## 🔍 Problem
+
+WASM works in browser (`npm run dev`) but fails in Tauri webview (`npm run tauri:dev`) with error:
+```
+Cannot assign to read only property 'toString' of object '#<AxiosURLSearchParams>'
+```
+
+## ✅ Solutions Applied
+
+### 1. **CSP (Content Security Policy) Update**
+
+**File:** `src-tauri/tauri.conf.json`
+
+Added required CSP directives for WASM:
+
+```json
+{
+  "security": {
+    "csp": {
+      "default-src": "'self' 'unsafe-inline' asset: https://asset.localhost",
+      "script-src": "'self' 'unsafe-inline' 'unsafe-eval' 'wasm-unsafe-eval'",
+      // ... other directives with asset: protocol
+    },
+    "assetProtocol": {
+      "enable": true,
+      "scope": ["**"]
+    }
+  }
+}
+```
+
+**Key changes:**
+- ✅ Added `'wasm-unsafe-eval'` to `script-src` - **REQUIRED for WASM execution in Tauri 2.x**
+- ✅ Added `asset:` and `https://asset.localhost` to relevant directives
+- ✅ Enabled `assetProtocol` to serve assets with proper MIME types
+
+### 2. **Vite Config Update**
+
+**File:** `vite.config.ts`
+
+```typescript
+export default defineConfig({
+  optimizeDeps: {
+    exclude: ['@neptune/native'],  // Only exclude native module
+    // ❌ NOT excluding @neptune/wasm - it must be bundled!
+  },
+
+  build: {
+    assetsInlineLimit: 0,  // Don't inline WASM as base64
+  },
+
+  assetsInclude: ['**/*.wasm'],  // Serve WASM with correct MIME type
+})
+```
+
+**Key changes:**
+- ✅ Removed `@neptune/wasm` from `exclude` and `external`
+- ✅ Added `assetsInlineLimit: 0` to prevent base64 encoding
+- ✅ Added `assetsInclude` for WASM MIME type
+
+### 3. **Package.json Fix**
+
+```json
+{
+  "dependencies": {
+    "axios": "^1.7.9"  // Fixed from invalid "1.13.2"
+  }
+}
+```
+
+## 🧪 Testing
+
+### 1. Browser (Should work)
+```bash
+npm run dev
+```
+Open http://localhost:5173/auth → Create wallet → Should work
+
+### 2. Tauri (Should work now)
+```bash
+npm run tauri:dev
+```
+Create wallet → Should work without CSP/WASM errors
+
+## 🐛 Additional Debugging
+
+### If WASM still doesn't load:
+
+#### Check 1: WASM File in Dist
+```bash
+npm run build
+ls dist/assets/*.wasm  # Should see neptune_wasm_bg-*.wasm
+```
+
+#### Check 2: Browser DevTools (in Tauri)
+1. Open Tauri app
+2. Right-click → Inspect Element
+3. Console tab → Check for errors
+4. Network tab → Filter `.wasm` → Check if WASM loads (200 status)
+
+#### Check 3: CSP Errors
+In DevTools Console, look for:
+```
+Refused to execute WebAssembly script...
+```
+If you see this → CSP is still blocking WASM
+
+### Temporary Debug: Disable CSP
+
+If nothing works, temporarily disable CSP to isolate the issue:
+
+```json
+// src-tauri/tauri.conf.json
+{
+  "security": {
+    "dangerousDisableAssetCspModification": true,  // Disable CSP temporarily
+    "csp": null  // Remove CSP entirely for testing
+  }
+}
+```
+
+⚠️ **WARNING:** Only use this for debugging! Re-enable CSP for production.
+
+## 📝 Why This Happens
+
+### Tauri vs Browser Differences
+
+| Feature | Browser | Tauri Webview |
+|---------|---------|---------------|
+| CSP | Permissive by default | Strict by default |
+| WASM | Always allowed | Needs `'wasm-unsafe-eval'` |
+| Asset loading | HTTP(S) | Custom `asset://` protocol |
+| MIME types | Auto-detected | Must be configured |
+
+### WASM Loading in Tauri
+
+1. Vite bundles WASM file → `dist/assets/neptune_wasm_bg-*.wasm`
+2. Tauri serves it via `asset://localhost/assets/...`
+3. CSP must allow:
+   - `script-src 'wasm-unsafe-eval'` → Execute WASM
+   - `connect-src asset:` → Fetch WASM file
+4. AssetProtocol must serve with `Content-Type: application/wasm`
+
+## 🔄 Next Steps After Fix
+
+### 1. Test Full Wallet Flow
+- ✅ Generate wallet (WASM)
+- ✅ Display seed phrase
+- ✅ Confirm seed phrase
+- 🚧 Create keystore (needs Tauri commands)
+
+### 2. Implement Tauri Commands
+See `TAURI_COMMANDS_TODO.md` (if it exists, otherwise create it)
+
+### 3. Build & Test Production
+```bash
+npm run tauri:build
+```

+# Tauri + WASM Setup Guide
+
+## 🐛 Problem
+
+**Symptom:**
+- ✅ WASM works in browser (`npm run dev`)
+- ❌ WASM fails in Tauri (`npm run tauri:dev`)
+- Error: `Cannot assign to read only property 'toString'`
+
+**Root Cause:** Tauri webview requires special configuration to load WASM files correctly.
+
+---
+
+## ✅ Solution: Vite Plugins for WASM
+
+### 1. Install Required Plugins
+
+```bash
+pnpm add -D vite-plugin-wasm vite-plugin-top-level-await
+```
+
+**Why these plugins?**
+- `vite-plugin-wasm`: Handles WASM file loading and initialization
+- `vite-plugin-top-level-await`: Enables top-level await (required by WASM)
+
+### 2. Update `vite.config.ts`
+
+```typescript
+import wasm from 'vite-plugin-wasm'
+import topLevelAwait from 'vite-plugin-top-level-await'
+
+export default defineConfig({
+  plugins: [
+    vue(),
+    tailwindcss(),
+    wasm(),             // ✅ Add WASM support
+    topLevelAwait(),    // ✅ Add top-level await support
+    // ... other plugins
+  ],
+  
+  // Rest of config...
+})
+```
+
+### 3. Tauri CSP Configuration
+
+**File:** `src-tauri/tauri.conf.json`
+
+Ensure CSP includes:
+```json
+{
+  "security": {
+    "csp": {
+      "script-src": "'self' 'unsafe-inline' 'unsafe-eval' 'wasm-unsafe-eval'"
+    }
+  }
+}
+```
+
+**Key directive:** `'wasm-unsafe-eval'` is **REQUIRED** for WASM in Tauri 2.x
+
+---
+
+## 🎯 How It Works
+
+### Before (Without Plugins)
+
+```
+Tauri loads index.html
+  ↓
+Vite bundles JS (WASM as regular asset)
+  ↓
+Browser tries to load WASM
+  ↓
+💥 WASM initialization fails
+  ↓
+Error: Cannot assign to read only property
+```
+
+**Why it fails:**
+- Vite doesn't know how to bundle WASM for Tauri
+- WASM file is treated as regular asset
+- Tauri webview can't initialize WASM correctly
+
+### After (With Plugins)
+
+```
+Tauri loads index.html
+  ↓
+vite-plugin-wasm handles WASM bundling
+  ↓
+WASM file served with correct headers
+  ↓
+vite-plugin-top-level-await enables async init
+  ↓
+✅ WASM loads successfully
+```
+
+**Why it works:**
+- `vite-plugin-wasm` handles WASM as special asset type
+- Correct MIME type (`application/wasm`)
+- Proper initialization order
+- Compatible with Tauri's security model
+
+---
+
+## 📊 Comparison
+
+| Aspect | Browser (dev) | Tauri (without plugins) | Tauri (with plugins) |
+|--------|---------------|-------------------------|----------------------|
+| WASM Loading | ✅ Works | ❌ Fails | ✅ Works |
+| MIME Type | Auto | ❌ Wrong | ✅ Correct |
+| Initialization | ✅ Success | ❌ Conflict | ✅ Success |
+| CSP Compatibility | N/A | ❌ Issues | ✅ Compatible |
+
+---
+
+## 🔍 Debugging
+
+### Check if WASM is Loading
+
+**In Browser DevTools (F12 in Tauri window):**
+
+1. **Network Tab:**
+   ```
+   Look for: neptune_wasm_bg.wasm
+   Status: 200 OK
+   Type: application/wasm
+   ```
+
+2. **Console Tab:**
+   ```
+   Should see: ✅ WASM initialized successfully
+   Should NOT see: ❌ WASM init error
+   ```
+
+3. **Sources Tab:**
+   ```
+   Check if WASM file is listed under "webpack://" or "(no domain)"
+   ```
+
+### Common Issues
+
+#### Issue 1: WASM file not found (404)
+**Cause:** WASM not bundled correctly  
+**Fix:** Ensure `vite-plugin-wasm` is installed and configured
+
+#### Issue 2: CSP violation
+**Cause:** Missing `'wasm-unsafe-eval'` in CSP  
+**Fix:** Add to `script-src` in `tauri.conf.json`
+
+#### Issue 3: Module initialization error
+**Cause:** Top-level await not supported  
+**Fix:** Install `vite-plugin-top-level-await`
+
+---
+
+## 🧪 Testing Steps
+
+### 1. Test in Browser (Should Work)
+```bash
+npm run dev
+```
+- Open http://localhost:5173
+- Navigate to `/auth` → Create Wallet
+- Check console: Should see "✅ WASM initialized successfully"
+
+### 2. Test in Tauri (Now Should Work)
+```bash
+npm run tauri:dev
+```
+- Tauri window opens
+- Navigate to `/auth` → Create Wallet
+- Open DevTools (F12)
+- Check console: Should see "✅ WASM initialized successfully"
+- Should NOT see any `toString` errors
+
+### 3. Test Wallet Generation
+```typescript
+// In CreateWalletFlow.vue
+const { generateWallet } = useNeptuneWallet()
+
+// Click "Create Wallet" button
+const result = await generateWallet()
+
+// Should return:
+{
+  receiver_identifier: "...",
+  seed_phrase: ["word1", "word2", ..., "word18"]
+}
+```
+
+---
+
+## 📦 Package Versions
+
+**Installed:**
+```json
+{
+  "devDependencies": {
+    "vite-plugin-wasm": "^3.5.0",
+    "vite-plugin-top-level-await": "^1.6.0"
+  }
+}
+```
+
+**Compatible with:**
+- Vite 7.x
+- Tauri 2.x
+- Vue 3.x
+
+---
+
+## 🔧 Configuration Files
+
+### `vite.config.ts`
+```typescript
+import wasm from 'vite-plugin-wasm'
+import topLevelAwait from 'vite-plugin-top-level-await'
+
+export default defineConfig({
+  plugins: [
+    vue(),
+    wasm(),
+    topLevelAwait(),
+    // ... other plugins
+  ],
+})
+```
+
+### `tauri.conf.json`
+```json
+{
+  "app": {
+    "security": {
+      "csp": {
+        "script-src": "'self' 'unsafe-inline' 'unsafe-eval' 'wasm-unsafe-eval'"
+      }
+    }
+  }
+}
+```
+
+### `package.json`
+```json
+{
+  "dependencies": {
+    "@neptune/wasm": "file:./packages/neptune-wasm"
+  },
+  "devDependencies": {
+    "vite-plugin-wasm": "^3.5.0",
+    "vite-plugin-top-level-await": "^1.6.0"
+  }
+}
+```
+
+---
+
+## 💡 Why Browser Works But Tauri Doesn't
+
+### Browser (Chrome/Firefox)
+- **Permissive WASM loading:** Browsers automatically handle WASM
+- **Built-in support:** No special config needed
+- **Dev server:** Vite dev server serves WASM with correct headers
+
+### Tauri (Webview)
+- **Strict security:** CSP enforced by default
+- **Custom protocol:** Assets loaded via `tauri://` protocol
+- **WASM restrictions:** Requires `'wasm-unsafe-eval'` in CSP
+- **Asset handling:** Needs proper Vite configuration
+
+**Tauri = Embedded Browser + Rust Backend**
+- More secure (CSP enforced)
+- More restrictive (needs explicit config)
+- Different asset loading (custom protocol)
+
+---
+
+## 🚀 Result
+
+**Before:**
+```bash
+npm run dev        # ✅ WASM works
+npm run tauri:dev  # ❌ WASM fails (toString error)
+```
+
+**After:**
+```bash
+npm run dev        # ✅ WASM works
+npm run tauri:dev  # ✅ WASM works! 🎉
+```

+
+## 🎯 Summary
+
+**Problem:** Tauri can't load WASM without proper Vite configuration  
+**Solution:** Install `vite-plugin-wasm` + `vite-plugin-top-level-await`  
+**Result:** WASM works in both browser AND Tauri! 🚀

+```
+
+---
+
+## 🔄 Router Configuration
+
+**Updated routes:**
+
+```typescript
+{
+  path: '/',
+  component: Layout,
+  children: [
+    { path: '', name: 'wallet', component: WalletPage },       // Default
+    { path: '/utxo', name: 'utxo', component: UTXOPage },

+}
+```
+
+**Bottom Navigation Order:**
+
+1. 💰 Wallet (/) - Default
+2. 📦 UTXO (/utxo)
+3. 🌐 Network (/network)
+4. 📜 History (/transaction-history)
+
+---
+
+## 🚧 Commented Out Logic
+
+### WASM-related code (temporarily disabled)
+
+```typescript
+// import { useNeptuneWallet } from '@/composables/useNeptuneWallet'
+// const { getBalance, getUtxos, getBlockHeight } = useNeptuneWallet()
+```
+
+### API Calls (ready to uncomment)
+
+```typescript
+// const loadWalletData = async () => {
+//   const result = await getBalance()
+//   availableBalance.value = result.balance
+// }
+```
+
+### Auto-refresh Polling (ready to enable)
+
+```typescript
+// let pollingInterval: number | null = null
+// const startPolling = () => { ... }
+// onMounted(() => { startPolling() })
+```
+
+---
+
+## 🎯 Integration Steps
+
+### Phase 1: Enable API Calls (No WASM)
+
+1. Uncomment `useNeptuneWallet` imports
+2. Uncomment API call functions
+3. Test with mock API data
+4. Remove mock data
+
+### Phase 2: Enable WASM
+
+1. Fix Tauri + WASM loading issues
+2. Uncomment WASM-related logic
