Getting started
Pick the path that matches your role:
I’m launching a protocol, operate an L2, develop a crypto wallet and need a security audit → Start with Security Audits
I need real-time hack detection & blocking → Start with Phalcon Security
I need AML/CFT screening & monitoring → Start with Phalcon Compliance (add MetaSleuth for tracing)
I’m analyzing an exploit or suspicious transaction → Use Phalcon Explorer + Security Incidents Library
I operate an L2 and want infrastructure-grade protection → Explore STOP
I manage a treasury and want to protect our Safe → Use Safe{Wallet} Monitor
I’m building transaction insights into my product → Integrate Transaction Simulation API
I want MEV protection for my swaps → Configure Anti‑MEV RPC
