Frozen Crypto Account Lawyer

A frozen crypto account is not one problem with one answer. The funds may be held by the exchange under its own anti-money-laundering rules; blacklisted at contract level by the company that issued the token; blocked because a U.S. sanctions program reaches you, your counterparty or the address; or restrained on the instruction of an investigating authority or a court. From the customer side all four look the same — the balance is visible, withdrawal is disabled, and support keeps sending the same template reply.

They are not the same, and the wrong route costs time that the right one would not. A compliance hold is cleared with an evidenced source-of-funds file addressed to the right department. A sanctions block is not cleared that way at all: an exchange within reach of the sanctions regime is legally barred from releasing blocked property, so the application goes to the regulator rather than to the platform. Our practice covers OFAC crypto sanctions, AML defense and financial investigations, and every frozen-funds case starts with establishing which of the four situations you are in.

1. The exchange froze the account after a compliance review

Licensed exchanges are required to monitor transactions and to investigate the alerts their systems raise; in practice those alerts come from blockchain-analytics tools. The usual triggers are a deposit that traces back to a mixer, a sanctioned cluster, a darknet marketplace or a gambling service; turnover that jumps out of line with the declared profile; a fraud or chargeback complaint from a counterparty; or a re-verification request that was never completed. The account is restricted while a compliance officer decides whether to release it, hold it, or file a report.

Most people misread who the decision is for. The compliance officer is not weighing your inconvenience against the platform’s — they are building a file that has to stand up in front of their own regulator. A response that gives them that file moves the case; an angry ticket does not.

2. USDT frozen by the issuer: what a stablecoin blacklist actually does

USDT and USDC are issued by centralized companies, and on the chains where their contracts implement a blacklist the issuer can flag an address. When that happens the tokens stay in the wallet and remain visible on the blockchain, but any attempt to move them fails at the contract — the transaction does not go through at all. Completed past transfers are not undone; the balance is simply immobilized.

No exchange, wallet provider or third-party “recovery” service can move a blacklisted stablecoin balance. Only the issuer can lift the flag, and issuers generally state that they act on requests from law enforcement or on a sanctions listing — which means the real question is not how to move the tokens, but who asked for the freeze and on what basis. That is also why paid recovery offers are thickest here and make the least sense: if the block sits in the contract, the only counterparties that matter are the issuer and whoever instructed it.

3. A sanctions designation blocks the funds

The U.S. Office of Foreign Assets Control publishes digital currency addresses on the SDN List as identifiers of designated persons, alongside names and company details. If you or your counterparty are designated — or the address is published as an identifier of a designated person — a U.S. person, and in practice any exchange with U.S. exposure, must act on it rather than simply return the funds.

Whether the property is blocked or the transfer is instead rejected depends on the program involved. The difference decides whether the funds sit in a blocked account or go back to the sender, and it is the first thing to establish from the notice. Either way the platform cannot resolve it for you: the route runs through OFAC, and it is set out on our pages on OFAC blocked assets and OFAC licensing.

4. Law enforcement or a court ordered the freeze

Funds can be restrained as part of a criminal investigation, under a court order, or at the request of a foreign authority through mutual legal assistance. Here the exchange is a custodian complying with an instruction and has no discretion at all — correspondence with its support desk changes nothing. The case is argued where the order was made: with the investigating authority, before the court, or through the procedure that allows a third party to assert an interest in restrained property.

Four questions usually identify the case:

• Do the tokens still move on-chain? A balance in your own wallet whose transfers fail points to the issuer. A balance inside an exchange account points to the platform.
• Is it the whole account or one asset? One stablecoin immobilized while everything else moves is an issuer or address-level match. A full account lock is a compliance review.
• What does the notice say? A document request is a compliance hold. Wording about blocked property or a designated person is sanctions. A case number or a named authority is a court or law-enforcement order.
• Is the subject you or your counterparty? And it is not only about who is on the list: property of an entity owned 50 per cent or more by designated persons is blocked even though the entity itself never appears on it.

You can ask the platform in writing for the legal basis of the restriction and, where one exists, the authority behind it. Some providers answer; many do not, and the absence of an answer is not by itself evidence of anything — where a suspicious activity report has been filed, disclosure rules in most jurisdictions bar the provider from saying so, and a routine compliance review may equally go unexplained. The classification is therefore usually built from the wording of the notice, the on-chain position, and the pattern of what was and was not restricted.

A source-of-funds file built for the compliance officer, not for you

Not screenshots and assurances: a documented chain from the origin of the money to the deposit in question. Employment or business income with supporting statements, sale agreements, exchange records, tax filings where they exist, and an explanation of every hop the analytics report flagged. Where a deposit passed through a counterparty the platform treats as high risk, the file has to meet that point head-on rather than talk around it.

A formal written response instead of a support ticket

Compliance decisions are not made by the agents who answer chat. A letter from counsel, sent to the compliance or legal function, setting out the facts, attaching the evidence and identifying the provision the platform is relying on, reaches a different desk and creates a record. Any later escalation is built on that record.

An unblocking application where the match was mistaken

Where the block came from a mistaken match rather than a real nexus — a shared name, a partial identifier, an address wrongly attributed to you — the route is an application to unblock under 31 CFR § 501.806, not a license. This is the most common favorable outcome in sanctions-driven freezes, and it turns on documentary proof of identity rather than on argument.

An OFAC specific license where the nexus is real

Blocked property is released by authorization, not by negotiation. A specific license application explains who the parties are, how the property came to be blocked, and why releasing it is consistent with the sanctions program — for example where a general license or statutory exemption already covers the transaction. See our page on how these applications are structured.

A delisting petition when you are the designated party

If your own name or company is designated, the balance will not come free until the designation is challenged — a reconsideration request under 31 CFR § 501.807, which is the subject of our page on SDN List removal.

Regulator and ombudsman complaints against the platform

Exchanges hold licenses in specific jurisdictions, and most of those regimes provide a supervisory complaint route — to a financial regulator, or to an ombudsman scheme — that sits outside the platform’s own process. It is rarely the jurisdiction the customer lives in, and it is almost never the one named in the app. Where a properly evidenced submission has produced no decision, this is the channel that obliges someone other than the exchange to look at the file.

Civil proceedings and interim relief

Where the balance justifies it, a claim against the custodian is available: for return of the property, for disclosure of the basis on which it was retained, and in some jurisdictions for interim relief preserving the position while the claim runs. Viability turns on the contract, the governing law and forum clauses, and the sum at stake — which is why this is assessed rather than assumed. Some accounts are not worth litigating, and we say so.

Representation before the authority that ordered the freeze

Where funds are restrained in an investigation, the route is to establish on the record that the property is yours and that its origin is lawful — and, where the restraint is disproportionate or has outlived its basis, to put that to the body that can lift it. This is criminal and asset-recovery work, done in the jurisdiction that issued the order.

The exact wording of every notice or in-app message the platform has sent you, the transaction hash or deposit ID of whatever triggered the review, and the date the balance stopped moving. That is enough to place the case in one of the four categories and to say whether it is worth pursuing — before you engage anyone.

1. Classify the freeze. We read the notice, the account correspondence and the on-chain position, and tell you which of the four situations applies — including when the honest answer is that the prospects are poor.
2. Trace the transactions. An independent look at where the flagged funds came from, so that the file answers the analytics report rather than contradicting it.
3. Build the evidence pack. Source of funds and source of wealth, ownership of the address, the commercial reason for the transfers, translated and certified where the recipient requires it.
4. Correspond with the platform or the issuer where correspondence can still change the outcome — that is, in compliance holds and issuer blacklists, not where a court order is in force.
5. File with OFAC where sanctions are involved. Unblocking applications for mistaken matches, specific license applications, reconsideration requests where a designation is the cause, and — where we act for the institution holding the property — the blocked-property reporting it owes OFAC.
6. Act before the authority or the court where the freeze comes from an investigation, including third-party claims to restrained property.
7. Escalate to the supervisory or ombudsman route in the platform’s licensing jurisdiction, or advise on a civil claim, when a hold outlives its justification.

The sanctions side of this work is jurisdiction-specific. We handle U.S. measures administered by OFAC, together with UK restrictive measures and OFSI licensing and EU sanctions, and we work with local counsel where a freeze is anchored in a court order abroad. Exchange and AML matters are handled against the rules of the jurisdiction where the platform holds its license, which is often not the country the customer lives in.

Clients come to this practice from banking, trading and crypto businesses as well as from private individuals holding their own assets; the underlying compliance questions are the same ones covered in our work on AML/CFT systems and due diligence.

• Sending an incomplete story first and correcting it later. The initial explanation is kept on file and compared with everything that follows. Inconsistencies are treated as a red flag in their own right.
• Opening a second account or moving the remaining balance out. Both are readily read as evasion, and can turn a temporary review into a closed account and a filed report.
• Ignoring the sanctions question. If the cause is a designation or a blocked-property match, time spent arguing with support is time not spent on the filing that could actually work.
• Letting deadlines pass. Document requests from the platform and challenges to restraint orders run to time limits, and missing them narrows the options that remain — even where the sanctions filings themselves have no statutory deadline.
• Talking to investigators without counsel when the freeze is part of a criminal case, on the assumption that explaining once will end it.

No lawyer can guarantee that frozen funds will be released, and any offer that does should be treated as a warning sign. Whether a freeze can be lifted depends on facts that exist before anyone is instructed: where the funds came from, who the counterparty was, whether a designation is involved, and what the deciding body is required to do with the evidence available. Some cases are strong, some are slow, and some should not be pursued at all.

Services that advertise crypto recovery are not law firms: they cannot correspond with OFAC on your behalf, cannot file in court, and have no route to a token issuer. The lawyer who will run your file is named in the engagement letter, together with the bar or chamber they are admitted to and their registration number — check it before you pay anything, here or anywhere else.
