Crypto Exchange Account Frozen — AML Hold Lawyers

Of the ways crypto stops moving, an exchange restriction is the one that comes with the least explanation. The balance is visible, withdrawals are disabled, the reply is a template — “your account is under review” — and the only channel that answers is the one that cannot decide anything.

Our lawyers work on anti-money-laundering matters and on crypto sanctions, which means the first thing we do is separate the two. They look identical to the customer and are resolved in entirely different places.

Why a crypto exchange froze your account

A licensed exchange operates under anti-money-laundering obligations in whichever jurisdiction issued its licence. It is required to monitor transactions on a risk-sensitive basis and to screen counterparties against sanctions lists. In practice, platforms discharge that duty with blockchain analytics tools, and it is an analytics alert that usually triggers the restriction — which is what “acting” looks like from the outside while a compliance officer decides whether to release the account, keep the hold, or report it to the financial intelligence unit (a SAR in the US, an STR in most other regimes).

The triggers that generate those alerts are fairly consistent:

• a deposit that analytics software traces back to a mixer, a sanctioned cluster, a darknet marketplace, a high-risk gambling service, or a known hack;
• turnover, counterparties or geography that no longer match the profile declared at onboarding;
• a fraud report or chargeback complaint filed by someone who sent you funds;
• P2P trading patterns that look like third-party payment processing;
• a periodic KYC refresh that was started and never completed, or documents that do not reconcile with each other.

Two structural facts explain the silence. First, the decision is not made by the agent answering chat — it is made by a compliance function that does not deal with customers at all. Second, where the platform has filed a suspicious activity report, tipping-off rules in the regimes that license it — the EU anti-money-laundering directives, the UK Proceeds of Crime Act, the US Bank Secrecy Act — bar it from disclosing that a report was made. The bar is on disclosing the report, not on explaining anything at all.

A refusal to explain is therefore not necessarily obstruction; it may be the only lawful answer available. It also means silence cannot be read as a diagnosis — every category of hold looks the same from the customer side, which is why the classification has to be done from the notice and the on-chain facts instead.

Binance, Bybit, Coinbase: AML hold or sanctions block?

The pattern is the same whether the account sits at Binance, Coinbase, Kraken, Bybit, OKX or a smaller regional platform: the licence determines the escalation route, not the brand. What changes everything is which of five categories the freeze belongs to — because the wrong route costs time that the right one would not.

• AML compliance hold. The exchange is exercising its own discretion under its own rules. It can release the funds once it is satisfied. This page covers that situation.
• Sanctions block. The funds are blocked because a designation reaches you, your counterparty or the address. The platform is legally barred from releasing them, so the application goes to the regulator — see frozen assets under sanctions and release of blocked funds.
• Stablecoin issuer blacklist. The tokens themselves are immobilised in the smart contract by the company that issued them. No exchange can move them; see our page on stablecoin freezes.
• Exposure to a designated platform. If the funds passed through an exchange that has itself been sanctioned, the question is your own exposure, not the hold — see sanctioned crypto exchange.
• Law enforcement restraint. An order from an authority or a court. The exchange has no discretion and the case is argued where the order was made.

The wording of the notice, whether the restriction covers the whole account or one asset, and whether the platform asks for documents or stops responding altogether is usually enough to place the case at the first review, before any document is drafted.

If the institution holding the funds is a bank rather than a crypto platform, the screening stack and the complaint route are different — see our page on bank account compliance reviews. If the underlying question is a business’s own AML programme rather than a personal account, that is covered by our anti-money-laundering practice.

The AML check on your crypto: what compliance actually needs from you

A compliance officer is not deciding whether to believe you. They are deciding whether the file on their desk would survive an inspection by their supervisor. That changes what a useful response looks like.

A documented chain, not an explanation

Every claim about where the money came from should be attached to something a third party issued: employment contracts and payroll records, company accounts, a sale agreement for the asset that was liquidated, statements from the bank or exchange the funds left, tax filings where they exist. Screenshots and assurances carry no weight because they cannot be verified.

An answer to the specific flag

Generic disclosure does not close an alert about one particular deposit. If a transfer touched a counterparty the analytics report treats as high risk, the submission has to address that transfer directly — who the counterparty was, what the commercial relationship was, and why the chain of hops is what it is. Answering around the flag reads as evasion.

Consistency with everything you have already said

The initial explanation you gave in chat stays on file and is compared against everything that follows. Corrections that arrive later are not read as clarifications; they are read as a changing story, and they are one of the most reliable ways to turn a reviewable hold into a closed account.

Certified translations where they are required

Documents issued in a language the reviewing team does not work in are frequently set aside without comment. Where the platform’s licensing jurisdiction expects a certified or sworn translation, and occasionally notarisation of the underlying document, supplying it up front removes a round trip of correspondence.

When the crypto account freeze does not end: escalation

Where a properly evidenced submission produces no decision, the case moves out of the platform’s customer channel. What is realistically available depends entirely on where the exchange is licensed.

• A formal letter from counsel to the compliance or legal function, setting out the facts, attaching the evidence, identifying the contractual and regulatory provision relied on, and fixing a date for a response. Everything that follows is built on that record.
• A complaint to the licensing authority. Most supervisors will not order your funds released — that is not what they do. What a complaint does is create a supervisory record against the platform and, in regimes with a statutory complaints-handling duty, force a documented answer within a defined period. Whether that route exists at all depends on where the platform is licensed, and for some offshore platforms it does not exist.
• A data subject access request, where the platform falls under the GDPR or an equivalent regime. Expect the AML exemption to be applied to the analytics and reporting material: a request of this kind reliably recovers the KYC and account record, rarely the reason for the hold. Its value is evidential — the response fixes what the platform admits to holding.
• Civil proceedings against the custodian, where the balance justifies it. Read the terms first: most platform agreements impose arbitration in a named seat, an exclusive foreign forum and a class-action waiver, and those clauses decide the cost of the claim before its merits do.

Some accounts are not worth litigating and we will say so.

How our crypto lawyers work your case

• Read the notice, the account correspondence and the transaction history on-chain, and classify the freeze — including telling you when the prospects are poor.
• Trace the flagged transactions independently, so the submission answers the analytics report rather than contradicting it.
• Assemble and, where needed, translate and certify the source-of-funds and source-of-wealth pack.
• Make the written submission to compliance or legal, and run the correspondence to deadlines.
• Where the cause turns out to be sanctions, move the case to the correct filing — a specific licence application or a challenge to the designation. Where we hold the sanctions mandate ourselves, the file does not change hands.
• Escalate through whatever route the platform’s licence actually provides, or advise on civil proceedings, when a hold outlives its justification.

What no crypto lawyer can promise you

Nobody can guarantee that a frozen exchange balance will be released. The outcome depends on facts that exist before anyone is instructed: where the funds came from, who the counterparty was, what the platform’s analytics actually show, and whether a report has already gone to a financial intelligence unit. Some holds clear once the documents arrive. Some do not, and the honest advice is to stop spending on them.

Anyone who quotes a success rate, a fixed timeline, or a guaranteed release before seeing your notice is not describing a legal process.

Crypto recovery services are not law firms

Firms that advertise crypto recovery for a frozen or stolen balance cannot correspond with a regulator on your behalf, cannot file in court, and have no route to a token issuer. Several of the tactics they sell — moving the remaining balance, opening a replacement account, submitting a “corrected” statement of origin — actively damage the file they claim to be fixing.

The question that separates the two categories quickly is who the admitted lawyer on the file is, and against which bar or chamber you can check their registration. Ask it here, and ask it of anyone else you are considering.

Frozen crypto account: what to prepare before you contact us

Three things make the first consultation useful: the exact wording of every notice the platform has sent you, the transaction hashes or deposit IDs of whatever triggered the review, and the documents you already hold showing where the money came from. Do not open a second account, do not move the remaining balance, and do not send a revised version of an explanation you have already given. Each of those makes the file worse.

Send us those three things and one line about the origin of the funds, and we will tell you which of the five categories your freeze belongs to and whether it is worth instructing anyone.
