+# Configuration Path Update
+
+## Change Summary
+
+Updated the wallet storage location to use `~/.config/svmai/` directory instead of storing directly in the home directory.
+
+## Before
+
+**Storage Location:** `~/.svmai_wallets.json`
+- Wallet data stored directly in home directory
+- Hidden file (prefixed with `.`)
+
+## After
+
+**Storage Location:** `~/.config/svmai/wallets.json`
+- Follows XDG Base Directory specification
+- Organized in dedicated config directory
+- Separate from Solana's config directory (`~/.config/solana/`)
+
+## Changes Made
+
+### File: `src/secure_storage.rs`
+
+1. **Updated Constants:**
+   ```rust
+   // Before
+   pub const CONFIG_FILE_NAME: &str = ".svmai_wallets.json";
+   
+   // After
+   pub const CONFIG_FILE_NAME: &str = "wallets.json";
+   pub const CONFIG_DIR_NAME: &str = "svmai";
+   ```
+
+2. **Updated `get_config_path()` Function:**
+   ```rust
+   // Before
+   dirs::home_dir()
+       .map(|home| home.join(CONFIG_FILE_NAME))
+   
+   // After
+   dirs::config_dir()
+       .map(|config_dir| config_dir.join(CONFIG_DIR_NAME).join(CONFIG_FILE_NAME))
+   ```
+
+## Benefits
+
+1. **No Conflict with Solana:** Ensures svmai doesn't touch `~/.config/solana/` directory
+2. **Better Organization:** Follows standard config directory conventions
+3. **Platform Support:** Uses `dirs::config_dir()` which maps to:
+   - Linux: `~/.config/svmai/`
+   - macOS: `~/Library/Application Support/svmai/`
+   - Windows: `%APPDATA%\svmai\`
+
+## Migration Note
+
+Existing users with wallets in `~/.svmai_wallets.json` will need to manually move their encrypted wallet data to the new location if they want to preserve their wallets. The application will create a fresh wallet store in the new location.
+
+## Verification
+
+Build and test completed successfully:
+- ✅ Application compiles without errors
+- ✅ Config path uses `~/.config/svmai/wallets.json`
+- ✅ No interaction with `~/.config/solana/` directory
+- ✅ Backward compatibility maintained through environment variable override for tests
