This file provides guidance to WARP (warp.dev) when working with code in this repository.

Project Overview

This is a Multi-Chain Blockchain Analytics Platform that monitors and analyzes blockchain data across multiple networks including GLQ Chain (GraphLinq), Ethereum, Polygon, Base, Avalanche, and BNB Smart Chain. The system provides real-time monitoring, historical data processing, and comprehensive analytics for DeFi, DEX, and general blockchain activity.

Environment: This project is optimized for Linux/WSL (Windows Subsystem for Linux) environments and has been migrated from Windows to ensure better compatibility and performance.

Core Architecture

Multi-Chain Design

The system is built around a multi-chain architecture that can simultaneously process data from multiple blockchain networks:

  • Primary Network: GLQ Chain (local RPC at localhost:8545)
  • External Networks: Ethereum, Polygon, Base, Avalanche, BSC (via Infura)
  • Unified Data Model: All chain data flows into a single InfluxDB time-series database
  • Cross-Chain Analytics: Supports comparative analysis between different blockchain networks

Key Components

  1. Core Infrastructure (src/core/)

    • config.py: Multi-chain configuration management with environment variable substitution
    • multichain_client.py: Unified client for all blockchain networks
    • infura_client.py: Specialized client for Infura-based chains
    • multichain_influxdb_client.py: Time-series database operations

  2. Data Processing (src/processors/)

    • multichain_processor.py: Orchestrates multi-chain historical sync and real-time monitoring
    • historical_processor.py: High-performance batch processing (67+ blocks/sec)
    • realtime_monitor.py: Live blockchain monitoring with 2-second polling
    • monitoring_service.py: Web dashboard service with WebSocket updates

  3. Analytics Modules (src/analytics/)

    • token_analytics.py: ERC-20/721/1155 token transfer analysis
    • dex_analytics.py: DEX swap detection and liquidity tracking
    • defi_analytics.py: DeFi protocol interaction analysis
    • advanced_analytics.py: Cross-chain analytics and wallet clustering

Development Environment Setup

Prerequisites (Linux/WSL)

  • Operating System: Ubuntu 20.04+ or compatible Linux distribution
  • WSL: WSL2 recommended for Windows users
  • Python: Python 3.12+ (sudo apt install python3.12 python3.12-venv)
  • Git: Version control (sudo apt install git)
  • Docker: For running InfluxDB and GLQ Chain nodes

Initial Environment Setup

# Clone repository (if needed)
git clone <repository-url>
cd blockchain_data

# Create and activate Python virtual environment (Linux/WSL compatible)
python3 -m venv venv
source venv/bin/activate

# Upgrade pip and install dependencies
python -m pip install --upgrade pip
pip install -r requirements.txt

# Configure environment
cp .env.example .env
# Edit .env with your InfluxDB token and Infura project ID

Virtual Environment Management (CRITICAL)

Important: If migrating from Windows to WSL/Linux, the existing virtual environment must be recreated due to different binary formats.

# Remove old Windows venv (if migrating)
rm -rf venv

# Create new Linux-compatible venv
python3 -m venv venv

# Always activate before working
source venv/bin/activate

# Verify activation (should show path in venv)
which python

# Install/reinstall dependencies
pip install --upgrade pip
pip install -r requirements.txt
```bash

## Common Development Commands

### Environment Activation (Always First!)

```bash
# ALWAYS run this before any development work
source venv/bin/activate

# Verify virtual environment is active
which python  # Should show: /path/to/blockchain_data/venv/bin/python
```bash

### Database Setup

```bash
# InfluxDB should be running at http://localhost:8086
# Create organization: glq-analytics
# Create bucket: blockchain_data
# Generate API token and add to .env file
```bash

### Testing and Validation

```bash
# Test multi-chain connectivity
python test_multichain_simple.py

# Test system setup (legacy GLQ only)
python tests/test_sync_setup.py

```bash

### Real-time Monitoring

```bash

## Configuration Management

### Multi-Chain Configuration (`config/config.yaml`)

The system uses a hierarchical configuration system:

- **chains section**: Defines all supported blockchain networks
- **influxdb section**: Database connection settings  
- **processing section**: Batch sizes, worker counts, real-time settings
- **analytics section**: Feature flags for different analytics modules

### Environment Variables (`.env`)

Critical environment variables:

- `INFLUX_TOKEN`: InfluxDB API token (required)
- `INFURA_PROJECT_ID`: Infura API key for external chains (required)
- `MAX_WORKERS`: Parallel processing workers (default: 8)
- `ENABLED_CHAINS`: Comma-separated chain list (default: all)

### Chain-Specific Settings

Each chain supports:

- Individual enable/disable flags
- Provider-specific RPC/WebSocket URLs
- Network type and chain ID validation
- Rate limiting and timeout configurations

## Data Processing Architecture

### Historical Processing

The system processes historical blockchain data in parallel batches:

- **Batch Size**: 1000 blocks (configurable)

## Development Guidelines

### Linux/WSL Specific Considerations

#### File Permissions

```bash
# Make scripts executable if needed
chmod +x glq_analytics.py
chmod +x scripts/*.py

# Check file permissions
ls -la
```bash

#### Path Handling

- Use forward slashes `/` for all paths (Linux standard)
- Avoid Windows-specific path constructions
- Use `os.path.join()` or `pathlib.Path` for cross-platform compatibility

#### Environment Variables

```bash
# Check current environment
env | grep INFLUX
env | grep INFURA

# Set temporary environment variables
export INFLUX_TOKEN="your_token_here"
export MAX_WORKERS=8
```bash

### Adding New Chain Support

1. Add chain configuration to `config/config.yaml`
2. Update environment variables in `.env.example`  
3. Test connectivity with `test_multichain_simple.py`
4. Update documentation and schema files

### Creating Analytics Modules

1. Follow the pattern in `src/analytics/token_analytics.py`
2. Implement proper event signature detection
3. Add configuration flags in `config/config.yaml`
4. Include comprehensive unit tests
5. Update real-time processing integration

### Performance Optimization

- Use async/await patterns for I/O operations
- Implement batch processing for database writes
- Monitor memory usage with large datasets  
- Use connection pooling for blockchain RPC calls
- Implement proper error handling and retry logic

### Testing Strategy

- Unit tests for individual components
- Integration tests for multi-chain operations
- Performance tests with limited block ranges
- End-to-end tests with full sync validation

## Monitoring and Observability

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
```bash

#### Permission Errors

```bash
# Fix file permissions
chmod +x glq_analytics.py
chmod +x scripts/*.py

# Check current permissions
ls -la glq_analytics.py
```bash

#### Python Path Issues

```bash
# Check Python version and location
python3 --version
which python3
which python  # Should show venv path when activated
```bash

#### Package Installation Issues

```bash
# Update package manager
sudo apt update
sudo apt upgrade

# Install Python development headers if needed
sudo apt install python3-dev python3.12-dev

# Reinstall pip
python -m pip install --upgrade pip
```bash
