REAL-TIME THREAT IDENTIFICATION
Core Detection Capabilities
Our detection engine analyzes mempool and blockchain data to identify and alert on transaction-level threats before they impact your users or operations.
04
Custom Rule Engine
Define and deploy your own detection logic for specific transaction attributes, gas prices, or wallet behaviors. Tailor alerts to your application's unique risk profile.
05
Multi-Chain Coverage
Real-time detection across Ethereum, Polygon, Arbitrum, Optimism, and Base. Consistent threat modeling and alerting regardless of the underlying L1/L2 architecture.
06
Low-Latency Alerting
Receive webhook or API alerts within 500ms of a threat being identified in the mempool. Integrate directly with your trading systems, dashboards, or incident response workflows.

Frequently Asked Questions
Get clear answers on how our real-time detection service protects your DeFi protocol from front-running and transaction manipulation.
Our service is delivered as a high-availability API endpoint. Integration typically involves adding a pre-transaction validation call to our API from your mempool listener or transaction relayer. We provide client libraries for Node.js, Python, and Go, and full API documentation. Most teams complete integration in 1-2 development sprints.
