Why exchanges and OTC desks may freeze crypto assets

What compliance teams may request and how to prepare transaction evidence.

Compliance triggers

Platforms can initiate reviews based on source-of-funds questions, transaction history, external risk signals or internal monitoring.

What evidence matters

A coherent transaction chronology, wallet ownership evidence where applicable and supporting documents can make a request easier to review.

What not to assume

A risk label is not the same as proof of wrongdoing. Technical analysis should distinguish blockchain facts from third-party classifications.

Platform decision

Only the platform can decide whether and when an account or transfer is released. Technical materials support the process but do not guarantee an outcome.
