DeFiMon includes a high perfomance transaction analysis engine with the rule syntax allows to precisely describe custom rules to alert about the project-specific events and many different types of attacks.

Notifications
DeFiMon is equipped with the API and different notification types including web hooks and Telegram.

Dashboard
The dashboard contains statistics about the suspicious and bridged funds, real-time exploits, and vulnerabilities detected in code. We constantly monitor various chains to detect hacks and new exploitable issues.




Why Decurity?
We are a team of veteran hackers who dived into the blockchain and smart contract security in the early days. Under our supervision, an audit is not just a filing of the checklist but rather a full-fledged research.
