MULTI-LAYER DEFENSE
How Our Hybrid Detection System Works
Our system combines on-chain monitoring with off-chain intelligence to detect and prevent fraud before it impacts your users or treasury. This layered approach delivers proactive security with minimal false positives.
01
Real-Time On-Chain Monitoring
Continuously scans transaction mempools and live blocks across 30+ EVM and non-EVM chains for suspicious patterns like flash loan attacks, sandwich trading, and wash trading.

02
Off-Chain Threat Intelligence
Correlates on-chain events with our proprietary database of known malicious addresses, phishing domains, and mixer activity to identify coordinated attacks and sophisticated social engineering.

03
Anomaly & Behavioral Scoring
Applies machine learning models to user transaction history and wallet interactions, generating a real-time risk score for every address and transaction to flag deviations from normal behavior.
