An automated compliance flag can lock up your savings overnight. The exchange isn't wrong to ask questions — but there's a real process to get a real answer, not an indefinite silence.
Why This Happens
Preventive balance freezes triggered by automated AML monitoring at large centralized exchanges are a genuinely widespread problem — an internal algorithm flags a deposit or withdrawal pattern, and the account is restricted pending a Source of Funds (SoF) review that can drag on with no clear timeline. This isn't unique to any one platform; it's a structural feature of how large exchanges manage regulatory risk at scale, and it can affect entirely legitimate account holders alongside genuinely suspicious activity.
Step 1: Identify and Isolate the Triggering Transaction
Determine which specific deposit or withdrawal triggered the review. Copy the exact transaction hash (TXID) from the blockchain, and download your full account transaction history for at least the past year in CSV format before you lose easy access to it.
Step 2: Build a Genuine Audit Trail
Gather concrete evidence tracing the legitimate origin of the funds in question:
- If the funds came from employment income: recent payslips or tax documents.
- If the funds came from prior trading gains on another platform: exported trading history from that platform, or blockchain explorer screenshots showing the tokens originated from a wallet you controlled.
- If the funds came from mining, staking, an inheritance, or an asset sale: the corresponding documentation for that specific category (see our Source of Funds Explanation Letter for the full structured breakdown by category).
Step 3: Submit a Complete, Formal Package
Open a higher-tier support ticket specifically for the compliance review (not general customer service), and submit your complete documentation proactively rather than waiting to be asked for each piece individually. Write an objective, factual cover explanation of the funds' origin and their intended use, with all supporting documents attached in a single organized PDF package. Avoid vague or evasive responses — a complete, well-organized submission is genuinely the fastest path through this process.
Step 4: Escalate If There's No Reasonable Response
If the exchange's compliance team hasn't provided a substantive response within roughly 15 business days, or continues holding your assets without articulating any specific concern, identify the licensed national entity operating the platform in your jurisdiction and file a formal administrative complaint with the relevant regulator — FinCEN (US), the FCA (UK), the CNMV (Spain), or AUSTRAC (Australia), depending on where the platform is actually licensed to serve you.
What This Means for You
Treat this as a documentation exercise, not an argument — a complete, well-organized submission moves faster than repeated complaints without new evidence. Generate a full compliance package rather than a single letter if your situation involves multiple income sources or a longer timeline, and escalate to the correct regulator only after giving the exchange's own process a genuine, documented chance to work.
