Network Indicators - Implementation Complete ✅¶

Note: This page is a point-in-time status snapshot and may be out of date relative to the current source. PRs welcome.

Date: November 25, 2025 Status: ✅ Fully Functional

🎯 What Was Implemented¶

Clear visual indicators throughout the UI to show when the app is running on a testnet (devnet, testnet, or localnet) vs production (mainnet).

📦 Files Created¶

1. Network Configuration¶

File: apps/web/src/config/network.ts Purpose: Centralized network configuration and helpers Key features: - Reads VITE_SOLANA_NETWORK from environment - Supports: mainnet-beta, testnet, devnet, localnet - Color-coded for each network type - Helper functions for network detection

2. Network Indicator Component¶

File: apps/web/src/components/NetworkIndicator.vue Purpose: Badge shown in header on testnets Features: - Warning emoji (⚠️) - Network name (DEVNET, TESTNET, etc.) - Color-coded gradient - Pulsing animation - Only visible on testnets

File: apps/web/src/components/TestnetBanner.vue Purpose: Full-width banner at top of page Features: - Test tube emoji (🧪) - Clear warning message - Network-specific text - Sticky positioning - Only visible on testnets

4. Documentation¶

File: docs/NETWORK-CONFIGURATION.md Purpose: Complete guide for network configuration Contents: - Setup instructions - Configuration options - UI indicators explanation - Testing checklist - Troubleshooting guide

🔧 Files Modified¶

1. AppHeader.vue¶

Changes: - Added NetworkIndicator component to desktop header - Added NetworkIndicator to mobile navigation - Updated styles for mobile layout

2. DefaultLayout.vue¶

Changes: - Added TestnetBanner component above header - Imports TestnetBanner component

3. WalletModal.vue¶

Changes: - Added network badge next to "Connect Wallet" title - Shows testnet name in modal - Color-coded badge matching network

4. useSolana.ts¶

Changes: - Now uses CURRENT_NETWORK.endpoint instead of hardcoded devnet - Respects environment configuration

5. .env.example¶

Changes: - Added VITE_SOLANA_NETWORK configuration - Added VITE_SOLANA_RPC_URL option - Documented all network options

🎨 Visual Indicators¶

On Devnet (Default)¶

Banner (Top of page):

🧪 Devnet Environment: This is a test network. No real funds are used.
   You can get free test SOL from a faucet.

- Color: Orange (#FFA500) - Position: Above header, sticky - Full width

Header Badge:

⚠️ DEVNET

- Color: Orange gradient - Position: Right side of header, before wallet button - Pulsing animation

Wallet Modal Badge:

Connect Wallet [DEVNET]

- Color: Orange - Position: Next to modal title - Small badge format

On Testnet¶

Same as devnet but: - Color: Red (#FF6B6B) - Text: "TESTNET" - More prominent warning

On Localnet¶

Same as devnet but: - Color: Purple (#9B59B6) - Text: "LOCALNET" - Indicates local development

On Mainnet¶

No indicators shown: - No banner - No header badge - No wallet modal badge - Clean production UI

🚀 How It Works¶

Configuration Flow¶

Environment Variable (.env):
```
VITE_SOLANA_NETWORK=devnet
```

Network Config (src/config/network.ts):

export const CURRENT_NETWORK: NetworkConfig =
  AVAILABLE_NETWORKS[VITE_SOLANA_NETWORK];

Components import and use:

import { CURRENT_NETWORK } from '@/config/network';

if (CURRENT_NETWORK.isTestnet) {
  // Show indicators
}

Conditional Rendering¶

All testnet indicators use v-if:

<div v-if="network.isTestnet" class="testnet-banner">
  <!-- Only renders on testnets -->
</div>

Dynamic Styling¶

Network colors are applied via CSS custom properties:

<div :style="{ '--network-color': network.color }">
  <!-- CSS can use var(--network-color) -->
</div>

✅ Testing Results¶

Visual Confirmation¶

✅ Devnet: Orange banner and badges visible at http://localhost:5173
✅ Header: Network indicator showing "⚠️ DEVNET"
✅ Banner: Testnet warning displayed at top
✅ Modal: Network badge in wallet connection modal
✅ Mobile: Responsive design works correctly
✅ HMR: All changes applied via hot module reload

Dev Server Status¶

✅ Running at http://localhost:5173
✅ All HMR updates applied
✅ No compilation errors
✅ No console errors

📱 Responsive Behavior¶

Desktop (> 860px)¶

Banner spans full width at top
Network badge visible in header (right side)
Wallet modal shows network badge

Tablet (481px - 860px)¶

Banner text adjusts sizing
Network badge in mobile menu when opened
Modal badge scales appropriately

Mobile (≤ 480px)¶

Banner uses smaller font
Network badge in mobile nav menu
Full-width wallet button
Compact network badge

🎯 Key Features¶

1. Clear User Communication¶

✅ Users always know which network they're on
✅ No confusion about real vs test funds
✅ Consistent indicators across all pages

2. Production Safe¶

✅ Mainnet shows no testnet indicators
✅ Environment-based configuration
✅ No accidental testnet UI in production

3. Developer Friendly¶

✅ Easy to switch networks (change .env)
✅ Custom RPC support
✅ Well-documented configuration

4. Visually Distinctive¶

✅ Color-coded by network type
✅ Multiple indicator locations
✅ Pulsing animation for attention
✅ Emoji icons for quick recognition

🔄 Network Switching¶

To Switch Networks¶

Stop dev server: Ctrl+C

Edit .env file:

# Change from devnet to testnet
VITE_SOLANA_NETWORK=testnet

Restart dev server:
```
npm run dev
```
Verify in browser:
Check banner color changed to red
Check header badge says "TESTNET"
Check wallet modal badge

Available Options¶

# Development/Testing (testnets)
VITE_SOLANA_NETWORK=devnet      # Orange indicators
VITE_SOLANA_NETWORK=testnet     # Red indicators
VITE_SOLANA_NETWORK=localnet    # Purple indicators

# Production (no indicators)
VITE_SOLANA_NETWORK=mainnet-beta

📊 Network Comparison¶

Network	Color	Use Case	Indicators Shown
Devnet	🟠 Orange	Development & Testing	✅ Yes
Testnet	🔴 Red	Pre-production Testing	✅ Yes
Localnet	🟣 Purple	Local Development	✅ Yes
Mainnet	🟢 (None)	Production	❌ No
