;; title: token-screener
;; version:
;; SecureToken Guardian - Decentralized Token Risk Assessment Platform Smart Contract
;;
;; An advanced blockchain security platform that provides comprehensive risk assessment
;; and threat intelligence for cryptocurrency tokens. The platform combines automated
;; analysis algorithms with community-driven intelligence to identify malicious tokens,
;; honeypots, rug pulls, and other security threats in real-time.
;;
;; Core Capabilities:
;; - Multi-dimensional token risk scoring with machine learning patterns
;; - Real-time honeypot and rug pull detection algorithms
;; - Community-powered threat intelligence and reputation systems
;; - Professional security auditor certification and tracking
;; - Automated transaction pattern analysis and fraud detection
;; - Comprehensive whitelist management for verified secure tokens
;; - Forensic analysis tools for suspicious wallet activities
