How to request an exchange to freeze stolen crypto?

Yes — a user can contact a cryptocurrency exchange directly and request a temporary freeze of stolen assets if they were transferred to a deposit address associated with that platform.

However, it’s important to understand the following:
🟡 An exchange will not freeze assets based solely on a user’s incident description.
The exchange must be able to see that the destination address has already been flagged via a markup — a classification in AML analytics systems that links the address to illicit activity.
If the exchange does not use the AML provider where the markup was created, it simply won’t detect the risk.
That’s why it’s more effective to initiate markup through Match Systems — we maintain integrations with dozens of cryptocurrency exchanges, OTC desks, payment services, blockchain explorers, and analytics platforms. Learn more about markup here.

To ensure that an exchange promptly reacts and freezes stolen assets, it is crucial to craft your request correctly. Your message should include the following details:

• Exchange contact information
  Each exchange has designated contact points for such requests. You can download a list of contact addresses here:

• Incident details:
   – Wallet address of the perpetrator
   – Transaction hash
   – Date and time of the transfer (UTC)
  

• Brief summary of the incident and a formal request to temporarily freeze the associated funds
