feat(tui): COMPLETE Live Transaction Feed! 🔴💸

0xrinegade · claude · 0xrinegade · commit ddd7070fc6d0 · 2025-11-23T11:52:38.000+03:00
**STREAMING COMPLETE:** Dashboard now shows LIVE blockchain transactions!

Live Transaction Feed Widget:
- 🔴 Red border with "LIVE Transactions" title
- Updates every 5 seconds with latest block transactions
- Shows up to 10 most recent transactions
- Beautiful 2-line format per transaction

Transaction Display Format:
Line 1: [Status Icon] [Type Icon] [Signature]
  - ✓ (green) for success / ✗ (red) for failure
  - 💸 Transfer / ⚙️  Contract / 📄 Unknown
  - Truncated signature (first 8 chars)

Line 2: [Timestamp] • [Amount SOL]
  - HH:MM:SS format
  - Amount in SOL (4 decimal places)
  - Styled with colors (gray timestamp, yellow amount)

Real-Time Data Fetching:
- Polls latest block from RPC every 5s
- Extracts up to 10 transactions
- Decodes transaction metadata
- Calculates SOL amount from balance diffs
- Detects transaction type (Transfer/Contract/Unknown)
- Checks success status from metadata

Transaction Type Detection:
- Transfer: Has instructions + SOL amount changed
- Contract: Has instructions but minimal SOL change
- Unknown: Empty instructions

Complete Live Dashboard Now Includes:
✅ Network Stats Panel (slot, epoch, TPS, validators, health)
✅ Live Transaction Feed (latest block transactions)
✅ 5-second auto-refresh for both
✅ Color-coded visual indicators
✅ Type icons and status symbols

Visual Hierarchy:
- Network stats: Cyan border (top priority info)
- Live transactions: Red border (LIVE feed emphasis)
- Both update simultaneously every 5s

Before: Static transfer history
After: LIVE blockchain transaction stream! 🔴

Data Flow:
RPC → get_block(latest_slot) → decode transactions →
parse metadata → detect type → format for display →
Update Arc&lt;Mutex&lt;Vec&lt;LiveTransaction&gt;&gt;&gt; → TUI renders

Try It:
```bash
./target/release/osvm research --tui &lt;WALLET&gt;
# Watch LIVE transactions stream in!
# See network stats + transaction feed update together!
```

The dashboard is now a **real-time blockchain monitor**! 🚀🔴💸
