# SolaceScanScout Navigation & Sync Status Review

> Historical note: This review records a point-in-time explorer status and remediation outcome. It is useful as troubleshooting history, not as the current operational state. For live explorer deployment status, use the current explorer runbooks, health checks, and endpoint inventory.

**Last Updated:** 2026-01-31  
**Document Version:** 1.0  
**Status:** Active Documentation

**Date:** 2026-01-30  
**Explorer URL:** https://explorer.d-bis.org  
**Status:** ✅ **FIXED: Explorer now syncing in real-time**

## Navigation Bar Review

### Current Navigation Structure

**Live Explorer (HTML/JS version):**
```
SolaceScanScout
The Defi Oracle Meta Explorer

Navigation Links:
├── 🏠 Home
├── 🧱 Blocks
├── 🔄 Transactions
├── 🌉 Bridge (Bridge Monitoring)
└── 🪙 WETH (WETH Utilities)

Search Box: Center (address/tx hash/block number)
```

**Next.js Frontend (layout.tsx - not deployed):**
```
SolaceScanScout
The Defi Oracle Meta Explorer

Navigation Links:
├── Blocks
├── Transactions
├── Search
└── Wallet (NEW - MetaMask integration)
```

### Navigation Features

| Feature | Status | Notes |
|---------|--------|-------|
| **Logo/Branding** | ✅ Good | "SolaceScanScout" + tagline "The Defi Oracle Meta Explorer" |
| **Search** | ✅ Working | Address/tx hash/block number search |
| **Blocks** | ✅ Working | View all blocks |
| **Transactions** | ✅ Working | View all transactions |
| **Bridge Monitoring** | ✅ Unique | CCIP bridge monitoring (differentiator) |
| **WETH Utilities** | ✅ Unique | WETH wrap/unwrap tools (differentiator) |
| **Wallet** | ⏳ Available | New MetaMask integration at `/wallet` |
| **Responsive** | ✅ Good | Sticky navbar, gradient design |

## Block Production & Sync Status

### Current Status (2026-01-30 21:07 UTC) — **FIXED**

| Source | Block Number | Timestamp | Status |
|--------|--------------|-----------|--------|
| **RPC (Chain)** | **1,581,086** | 2026-01-30 21:07 UTC | ✅ **Live** |
| **Explorer** | **1,581,090** | 2026-01-30 21:07:02 UTC | ✅ **SYNCED** |
| **Difference** | **+4 blocks** | **Real-time** | ✅ **SYNCING** |

> **Fixed on 2026-01-30**: Updated RPC endpoint from destroyed VMID 2500 (192.168.11.250) to working VMID 2201 (192.168.11.221).

### Analysis

**Problem:** SolaceScanScout stopped indexing blocks on **January 15, 2026** and has not synced since.

**Impact:**
- Explorer shows data that is **15 days old**
- Missing **532,208 blocks** of data
- Users see stale information (transactions, addresses, stats)
- Bridge monitoring and WETH utilities may show outdated data

**Chain is healthy:**
- RPC nodes are producing blocks normally (block 1,580,967 at 2026-01-30 21:02 UTC)
- Average block time: 2 seconds (per explorer stats API)
- Gas prices: 0.01 Gwei (low, healthy)

**Explorer stats API shows:**
```json
{
  "total_blocks": "1048760",
  "total_transactions": "13156",
  "total_addresses": "94",
  "average_block_time": 2000.0,
  "gas_prices": { "slow": 0.01, "average": 0.01, "fast": 0.01 }
}
```

## Root Cause Investigation

### Blockscout Service Status

```bash
● blockscout.service - Blockscout Explorer
     Active: active (exited) since Sat 2026-01-24 01:00:56 PST; 6 days ago
```

**Service is "active (exited)"** — This means:
- Docker Compose started successfully
- Containers were created
- But the service itself may not be running or indexing

### Last Service Restart

- **Last restart:** January 24, 2026 01:00 PST
- **Last indexed block:** January 15, 2026 16:57 UTC (9 days before restart)
- **Conclusion:** Restart did not resume indexing

### Likely Causes

1. **Blockscout container crashed/stopped** after January 15
2. **Database connection issue** preventing indexer from running
3. **RPC connection issue** (Blockscout can't reach Chain 138 RPC)
4. **Disk space issue** on VMID 5000
5. **Indexer stuck** on a specific block or transaction

---

## Recommendations

### Immediate Actions (Critical)

1. **Check Blockscout container status:**
   ```bash
   ssh root@192.168.11.12 "pct exec 5000 -- docker ps -a | grep blockscout"
   ```

2. **Check Blockscout logs for errors:**
   ```bash
   ssh root@192.168.11.12 "pct exec 5000 -- docker logs blockscout --tail 200"
   ```

3. **Check RPC connectivity from VMID 5000:**
   ```bash
   ssh root@192.168.11.12 "pct exec 5000 -- curl -X POST http://192.168.11.250:8545 \
     -H 'Content-Type: application/json' \
     -d '{\"jsonrpc\":\"2.0\",\"method\":\"eth_blockNumber\",\"params\":[],\"id\":1}'"
   ```

4. **Check disk space:**
   ```bash
   ssh root@192.168.11.12 "pct exec 5000 -- df -h"
   ```

5. **Check PostgreSQL status:**
   ```bash
   ssh root@192.168.11.12 "pct exec 5000 -- docker logs blockscout-postgres --tail 50"
   ```

### Fix Actions

**If container stopped:**
```bash
ssh root@192.168.11.12 "pct exec 5000 -- systemctl restart blockscout"
```

**If RPC connection issue:**
- Update `ETHEREUM_JSONRPC_HTTP_URL` in Blockscout env
- Ensure RPC endpoint is accessible from VMID 5000

**If database issue:**
- Check PostgreSQL logs
- Verify database not corrupted
- May need to re-index from scratch (last resort)

**If indexer stuck:**
- Restart Blockscout with fresh connection
- Check for specific error in logs about a problematic block/tx

## Navigation Improvements (Optional)

### Suggested Additions

1. **Add "Wallet" link** to live explorer navbar (currently only in Next.js version)
   - Link to `/wallet` for MetaMask integration
   - Icon: 🔗 or 🦊

2. **Add sync status indicator** to navbar
   - Show "Syncing..." or "Synced" with latest block number
   - Alert users if explorer is behind

3. **Add network selector** (future)
   - Switch between Chain 138, Ethereum Mainnet, ALL Mainnet
   - Useful when multi-chain support is added

4. **Add dark mode toggle** (UX enhancement)
   - Current design is light mode only

## Summary

| Item | Status | Priority |
|------|--------|----------|
| **Navigation Bar** | ✅ Good | Low (working well) |
| **Block Sync** | 🔴 **CRITICAL** | **HIGH** (15 days behind) |
| **RPC Health** | ✅ Good | - |
| **Blockscout Service** | ⚠️ Needs investigation | **HIGH** |

**Next Step:** Investigate why Blockscout stopped indexing on January 15 and restart/fix the indexer.
