Introducing EVM Crawler - The Ultimate Multi-Network Blockchain Monitoring Tool
We're thrilled to announce the official release of EVM Crawler - EasyLayer's most advanced blockchain monitoring solution yet! Building on the success of our Bitcoin Crawler, EVM Crawler brings enterprise-grade blockchain data processing to the entire Ethereum Virtual Machine ecosystem, supporting Ethereum, BSC, Polygon, Arbitrum, and dozens of other EVM-compatible networks.
The Evolution of Blockchain Monitoring
After the successful beta launch of Bitcoin Crawler, we received overwhelming feedback from developers who needed similar capabilities for EVM networks. The challenge was clear: while Bitcoin has a relatively straightforward transaction model, EVM networks involve complex smart contracts, multiple transaction types, and rapidly evolving standards like EIP-1559 and EIP-4844.
EVM Crawler addresses these complexities head-on, providing a unified interface for monitoring diverse EVM networks while respecting each network's unique characteristics.
What Makes EVM Crawler Special
🌐 Universal Multi-Network Support: Monitor Ethereum mainnet, BSC, Polygon, Arbitrum, Optimism, Avalanche, and any EVM-compatible network from a single codebase. Each network's specific features - from BSC's faster blocks to Polygon's EIP-1559 implementation - are handled automatically.
🔄 Advanced Transaction Processing: Full support for all transaction types including Legacy (Type 0), EIP-2930 (Type 1), EIP-1559 (Type 2), and cutting-edge EIP-4844 Blob transactions. Automatically extract gas prices, priority fees, and access lists across different network implementations.
📊 Smart Contract Interaction Tracking: Monitor contract deployments, function calls, event emissions, and state changes. Built-in ABI decoding support makes it easy to track specific contract interactions.
⚡ Real-Time Gas Analytics: Built-in gas price analysis with percentile-based recommendations. Perfect for building dynamic fee estimation systems that adapt to current network conditions.
🏗 Domain-Driven Architecture: Leveraging CQRS and Event Sourcing patterns, EVM Crawler provides a clean separation between data ingestion and business logic. Build maintainable applications that scale with your needs.

Binance Smart Chain (BSC)
- Optimized for faster block times (3 seconds)
- Legacy transaction focus with efficient gas price analysis
- BEP-20 token transfer monitoring
- Validator set change tracking
Polygon
- EIP-1559 implementation with unique base fee mechanics
- Checkpoint and state sync event processing
- MATIC token economics tracking
- Bridge transaction monitoring
Layer 2 Networks (Arbitrum, Optimism)
- L1 to L2 message tracking
- Sequencer batch processing
- Rollup-specific transaction costs
- Cross-layer state synchronization
Real-World Use Cases We've Seen
Our early adopters are already building incredible applications:
DeFi Analytics Platforms: Track liquidity pools, yield farming rewards, and arbitrage opportunities across multiple networks simultaneously.
Portfolio Management Tools: Monitor user wallets across all major EVM networks with unified transaction categorization and tax reporting.
MEV Research: Analyze MEV opportunities, bot behavior, and transaction ordering across different networks and time periods.
Cross-Chain Bridge Monitoring: Track asset movements between networks and detect potential security issues in real-time.
Getting Started with EVM Crawler
Installation is straightforward:
npm install @easylayer/evm-crawler
Here's a simple example that monitors gas prices across multiple networks:
import { bootstrap } from '@easylayer/evm-crawler';
import Model from './model';
bootstrap({
Models: [Model],
rpc: true,
});
Event-Driven Architecture: Built on proven event sourcing patterns, making it easy to replay data, add new features, and maintain audit trails.
Flexible Data Storage: Choose between SQLite for development, PostgreSQL for production, or implement custom storage adapters for your specific needs.
Multiple Access Patterns: Query your processed data via HTTP APIs, WebSocket subscriptions, or direct database access. Perfect for building responsive user interfaces.
Performance That Scales
EVM Crawler is engineered for high-throughput environments:
- Parallel Processing: Process multiple networks simultaneously without performance degradation
- Efficient State Management: Optimized memory usage even when processing large historical ranges
- Blockchain Reorganization Handling: Automatic reorg detection and state correction across all supported networks
- Rate Limiting & Error Recovery: Built-in retry mechanisms and rate limiting for reliable long-running operations
Production-Ready from Day One
Unlike many blockchain tools that require extensive customization for production use, EVM Crawler is designed with production environments in mind:
🔒 Security First: No private keys or sensitive data storage. Connect to your own nodes or trusted RPC providers.
📈 Monitoring & Observability: Built-in metrics, logging, and health checks make it easy to monitor your crawler instances.
🔄 High Availability: Stateless design enables easy horizontal scaling and zero-downtime deployments.
⚙️ Configuration Management: Environment-based configuration with validation ensures reliable deployments across different environments.
The future of blockchain development is multi-network, real-time, and data-driven. EVM Crawler makes that future accessible today.
Start building the next generation of blockchain applications. Your users will thank you. 🚀
