Sanctions screening is the reason a withdrawal that cleared fine last month can sit in review for a day. Every regulated venue runs your name, your address and sometimes the destination wallet through a screening list before it releases funds, and a partial match — a common surname, a transliteration with three spellings, a wallet that once touched a flagged address — is enough to stop the transfer while a human looks at it.
Understanding how sanctions screening works changes what you do about it. It explains why the hold happens, why support cannot speed it up, and why the same withdrawal succeeds on one venue and fails on another. Sanctions screening is not a judgement about you; it is a list-matching process with known failure modes.
- Two systems, one hold. Name screening happens at onboarding; wallet and counterparty screening happens at every transfer.
- A match is not a finding. Most hits are false positives from transliteration and common names, and they clear on review.
- Support cannot override it. Compliance decisions sit outside the support queue, so escalating usually only adds delay.
- Clean history helps. Receiving from identifiable sources and avoiding mixer-adjacent flows reduces the chance your address scores badly.
What sanctions screening actually checks
Two separate processes share the same name, and mixing them up is why people expect the wrong thing. Name screening runs against designated-persons lists. Wallet screening runs against blockchain analytics labels that cluster addresses into entities and attach risk scores.
Name screening at onboarding
Your legal name, date of birth and sometimes address are compared against published lists. Lists differ by jurisdiction, and a name that clears in one country can match in another because the transliteration conventions are not standardised. Common surnames and short names produce the most false positives.
Wallet screening at every transfer
When you withdraw, the destination address is scored. The score is built from what the analytics provider has seen that address do — whether it interacted with a sanctioned service, a darknet market, a mixer, or simply a cluster the provider considers high risk. Some venues screen the immediate counterparty only; others look several hops back.
Why the same withdrawal passes on one venue and fails on another
Three variables decide it, and none of them are under your control at the moment of withdrawal.
| Variable | What it changes | Practical effect |
|---|---|---|
| Screening provider | Different vendors label addresses differently | A wallet that scores low on one venue can be blocked on another |
| Hop depth | How far back the venue looks | A distant counterparty can taint an otherwise clean address |
| Risk appetite | Where the venue sets its own threshold | Conservative venues hold more transfers, for longer |
| Jurisdiction | Which lists apply to the venue | The same person can be clear in one country and flagged in another |
A compliance hold is not an accusation and it is not a customer service problem. It is a queue with a legal reason behind it, and the queue does not move faster because you are frustrated.
What to do when a withdrawal is held
- Read the notice carefully. A request for source-of-funds documentation is different from a sanctions match, and they need different responses.
- Answer exactly what is asked. Send the specific document requested; a folder of screenshots slows the review rather than helping it.
- Do not resubmit the same withdrawal repeatedly. Each attempt creates a new case and pushes you to the back of the queue.
- Ask which entity is holding the funds. If the venue operates through several licensed entities, knowing which one is reviewing tells you which rules apply.
- Keep the correspondence. If the hold becomes a dispute, a dated record of what was requested and what you supplied is the only thing that matters.
- Plan around it next time. Withdraw to an address with a clean, simple history rather than the one you have been reusing for years.
Reducing the chance of a hold
You cannot control the lists, but you can control what your addresses look like to a screening tool.
Keep receipts for large inflows
If a large balance arrives from somewhere a reviewer will ask about, keep the invoice, the sale record or the transfer trail. Producing it on day one turns a week-long review into a day-long one.
Avoid reusing addresses that have touched high-risk services
Address scoring is cumulative. An address that once received from a service the provider classifies as high risk carries that history forward, even if everything since then was ordinary.
