Introduction
Recent incidents highlight a growing trend where cryptocurrency exchanges require users to prove the legality of their fund sources. This shift reflects heightened regulatory scrutiny and the industry's push toward greater compliance.
Why Proof of Fund Sources Matters
Exchanges implement these measures to:
- Combat money laundering and illicit activities
- Comply with international sanctions and regulations
- Protect both platforms and legitimate users from financial risks
Common Triggers for Verification Requests
Sanctioned Address Connections
- Example: Funds originating from TornadoCash
- Platforms like OKX automatically flag these transactions
- Requires user documentation to prove unawareness of illicit origins
Case-Related Funds
- Stolen funds moving through exchange accounts
- Immediate freezing prevents further criminal activity
- Protects victims from additional losses
