2. Blockchain Analysis
   • Trace flow through mixers (Wasabi, Tornado Cash)
   • Identify CEX deposit patterns
3. Exchange Engagement
   • Submit preservation requests via CryptoISAC
   • Leverage Virtual Asset Service Provider (VASP) alliances
4. Asset Recovery
   • Monitor for off-ramping attempts
   • File seizure warrants under 18 U.S.C. § 983

2. Critical Investigative Tools

Investigative Challenges

1. Technical Barriers

• Privacy Coins: Monero (XMR), Zcash (ZEC) obfuscation
• Cross-Chain Bridges: Asset hopping between networks
• Decentralized Mixers: CoinJoin implementations

2. Legal Complexities

• Jurisdictional Conflicts: VASP registration disparities
• Mutual Legal Assistance delays (avg. 11 months)
• Asset Seizure limitations for DEX transactions
