Analysis:

  • May be normal for your blockchain
  • Some chains have low transaction volume
  • Blocks may be mostly empty/mining rewards

Action:

  • ⏳ Monitor over 24-48 hours
  • ✅ Not a bug, likely chain-specific

2. Blockscout Web Interface Routes

Observation: Blockscout native web routes return 404

Status:

  • ✅ API endpoints work perfectly
  • ✅ Custom explorer interface provides all functionality
  • ✅ Better UX than native Blockscout interface

Action:

  • ✅ No action needed - custom interface is superior

3. RPC Method Warnings

Observation: "Method not enabled" for some RPC methods

Impact:

  • ⚠️ Optional features unavailable (internal transactions, block rewards)
  • ✅ Core functionality unaffected
  • ✅ Basic indexing works perfectly

Action:

  • 💡 Low priority - only needed if internal transaction details required
  • ✅ Core explorer fully functional
