Updated Files Summary - Smart Contract Decoding

Overview

Successfully updated all Python and Go files that log transactions to include the latest smart contract parameter decoding capabilities.

Files Updated

1. event_monitor.py ✅

  • Shows full TX ID/Hash (no truncation)
  • Displays decoded smart contract info with human-readable format
  • Converts addresses to base58 (T...)
  • Formats token amounts with decimals
  • Status: Already updated in previous session

2. test_smart_contract_display.py ✅

  • Shows full TX Hash (no truncation)
  • Displays decoded smart contract parameters
  • Status: Updated

3. cmd/mvp/main.go ✅

  • Function: processEvents() (Address Monitor)

    • Verbose mode: Shows decodedMethod, methodSignature, paramAddresses, paramAddressesReadable, decodedAmount
    • Non-verbose mode: Shows decodedMethod

  • Function: storeBlockEvent() (Block Monitor)

    • Verbose mode: Shows complete decoded info for all transactions in block
    • Displays addresses in both hex and base58

4. internal/blockchain/monitor/block_monitor.go ✅

  • Function: extractTransactionData()
    • Now decodes smart contract parameters
    • Stores decoded info in ContractData["smartContract"]
    • Available to all consumers of BlockMonitor

5. internal/blockchain/monitor/address_monitor.go ✅

  • Function: extractEvent()
    • Already had smart contract decoding (from previous session)
    • Stores decoded info in EventData["smartContract"]

Python Monitor Output

🔍 SMART CONTRACT DECODED:
────────────────────────────────────────────────────────────────────────────────
📝 Function:     transfer(address,uint256)
🔑 Signature:    0xa9059cbb

💸 TOKEN TRANSFER:
   To (hex):     41737ab4479361c64983260bad00f3cab5549f125d
   To:           TLVohkv4mQT5yK9RdDFw8q8SJtESQGfVAo
   Amount:       6,710.000000 tokens
   Amount (raw): 6710000000

Decoded Information Included

For every smart contract transaction:

✅ Method Information

  • Method name: transfer(address,uint256)
  • Method signature: 0xa9059cbb

✅ Parameter Addresses

  • Hex format: 41737ab4...
  • Base58 format: TLVoh... (human-readable)
  • All addresses extracted from function parameters

✅ Token Amounts

  • Raw amount: 6710000000
  • Formatted: 6,710.000000 tokens

✅ Transaction Context

  • Block number
  • Transaction hash (full, not truncated)
  • From/To addresses (both hex and base58)
  • Success status

Usage

Python Monitor

source .venv/bin/activate
python event_monitor.py --address YOUR_ADDRESS

MVP Monitor (Go)

# Verbose mode - full decoding details
./bin/mongotron-mvp -address=YOUR_ADDRESS -verbose

# Comprehensive mode - all transactions
./bin/mongotron-mvp -monitor -verbose

Test Script

python test_smart_contract_display.py

Build Status

✅ bin/api-server - Built successfully
✅ bin/mongotron-mvp - Built successfully
✅ Python scripts - No build needed, updated and working

Documentation

  1. SMART_CONTRACT_DECODING_MONITOR.md - Python monitor details
  2. MVP_SMART_CONTRACT_DECODING.md - Go MVP monitor details
  3. ENHANCED_MONITOR_SUMMARY.md - Overall implementation summary
  4. SMART_CONTRACT_QUICK_REF.md - Quick reference guide

Verification

All systems updated and verified:

  • ✅ Event monitor (Python) - Shows decoded info
  • ✅ Test scripts (Python) - Updated to show full TX hash
  • ✅ API server - Stores decoded info in events
  • ✅ MVP monitor - Logs decoded info in verbose mode
  • ✅ Block monitor - Extracts decoded info for all transactions

Result

100% of transaction logging now includes smart contract parameter decoding with:

  • Human-readable function names
  • All addresses in both formats
  • Token amounts properly decoded
  • Complete transparency into smart contract interactions

🎉 All files updated and working!
