Your Binance withdrawals stopped overnight. The notice says risk control, or source of funds, or just “under review”. Support sends a template. The appeal comes back rejected, and now you are drafting a second appeal without knowing what Binance actually flagged.

Some freezes trace back to arbitrage patterns that automated monitoring reads as unusual activity. Others follow a law enforcement request, which no consultant can lift. Scammers circle both groups, promising a guaranteed unfreeze in exchange for a password or a 2FA code. We compared five firms on scope, honesty about the odds, fee transparency and what each one asks you to hand over.

A quick orientation before the detail.

How We Cut the Shortlist

We read service pages, practice descriptions, team bios and fee structures for the firms that mention frozen exchange accounts. This assessment rests on public information only. Nothing here comes from engaging the firms ourselves.

First we looked for a described process. A firm had to state what it does after the first call: document preparation, a demand letter, a legal position, a dialogue with case managers. We also looked for plain language about what the client is asked to hand over, and for candour about the odds of a result.

Then we looked at who each firm says it serves. Individuals, traders and businesses need different things. A company with an ownership structure to explain is a different case from a holder with one flagged transfer.

We also read practitioner discussions and weighed independent recognition where a firm stated it. Fee model counted too, because vague pricing is a bad sign in a stressful purchase.

The List

1. Unblock Exchange

Unblock Exchange is a Dubai-based independent adviser that prepares cases for users locked out by Binance and other exchanges, with no tie to any of them. The start is light: a short form with screenshots of the notice or email, a first response within 4 hours on average, and no request for passwords or 2FA codes at any point. Step one is diagnosis, sorting a security cooldown, a risk-control hold, a withdrawal flagged against a fraud pattern, a failed identity check or a Terms of Use deactivation.

Unblock Exchange sits among the compliance companies for frozen Binance account cases that open with an honest assessment, including advice to wait, and it never promises a guaranteed unfreeze. It is not a law firm, so court-ordered or law enforcement freezes go to a licensed lawyer. The team reads the transfers, counterparties and time windows to infer what Binance is probably reviewing. Then it drafts the source-of-funds explanation as a reply built for the exact channel Binance named.

Ideal for: individual holders, arbitrage traders and crypto businesses facing a Binance risk-control or source-of-funds review.

2. AML Zone

AML Zone names crypto businesses as its audience. It is a Dubai regulatory consulting and compliance project management firm founded by Natali Muravynets, who has worked in virtual asset compliance since 2016. Albert Voronkov is head of compliance.

Core work is licensing and AML programmes for virtual asset businesses across the UAE, Europe and offshore jurisdictions. Frozen accounts at Binance, Bybit, Kraken, WhiteBIT and OKX come on top of that.

For those cases the firm runs root-cause analysis, updates KYC and AML documents, clarifies the ownership structure and talks to exchange case managers, with legal support if required.

Fixed project-based fees keep scope defined, and work runs in English, Russian and Arabic. The stated audience is companies rather than individual holders, so a solo trader may find the framing built for someone else.

Ideal for: crypto projects and businesses needing KYC, AML and ownership documents refreshed after a freeze.

3. Prikhodko & Partners

A fintech practice headed by Taras Miroshnychenko sits inside this Kyiv law firm of 70+ specialists across many practice areas. The frozen-account work covers Binance, Coinbase, Kraken, Bybit and others, plus custodial wallets and corporate treasury crypto.

The process runs in three parts. Analyse the reason for the freeze and the exchange’s terms. Build a structured legal position. Assemble source-of-funds and source-of-wealth evidence.

After a rejected first appeal, that kind of written position gives a second appeal something the first lacked. Clients include individuals, founders and corporate teams across Eastern Europe and worldwide.

The same team handles VASP/CASP licensing and crypto fraud cases. That helps when a freeze overlaps with a fraud complaint.

Ideal for: founders and holders who want a lawyer-built position and wealth evidence for a Binance review.

4. Terms.Law

Terms.Law is the Law Office of Sergei Tokmakov, a California and Washington attorney practicing since 2011. The day job is contracts and legal documents for software companies. Intake is automated and the work is remote, under attorney supervision. The firm won the Law Firm category at the 2026 American Legal Technology Awards.

For frozen exchange accounts it offers attorney-drafted demand letters. They escalate past front-line support to the exchange’s legal and compliance teams and put the user’s cooperation on record. The firm says plainly that OFAC and law enforcement holds cannot be overridden by a letter.

Fees are fixed and agreed in writing. Filing and court appearances are not part of the package.

Ideal for: users stuck at front-line support who want a lawyer’s letter on record without litigation.

5. Dynamis LLP

Cases with a subpoena, a seizure or a regulator in the background belong with a litigation firm, and Dynamis LLP is built for that. Former federal prosecutor Eric Rosen and civil litigator Constantine Economides founded the US firm in 2023. It now has 20 lawyers in Boston, New York, Miami, Los Angeles and New Jersey, and Chambers USA ranks it.

Five of those lawyers are former federal prosecutors. The crypto practice covers criminal and regulatory defense before the SEC, DOJ and CFTC, civil crypto litigation, and asset recovery for fraud victims.

The firm also publishes guidance for account holders whose exchange account was frozen, subpoenaed or seized. When a freeze follows a law enforcement request, this is the kind of firm that matters.

Ideal for: holders whose Binance freeze involves law enforcement, a subpoena, a regulator or active litigation.

Questions to Settle Before You Pay Anyone

Which restriction is it? A cooldown, a risk-control hold and a Terms of Use deactivation need different replies, so ask any firm to name the one your account has.

Is any authority involved? A court order or law enforcement request puts the case with a litigator such as Dynamis LLP. Terms.Law says outright that a letter cannot override those holds.

Are you a company or an individual? AML Zone is organised around crypto businesses and their ownership documents. A holder with one flagged transfer may need less.

Do you need a legal position or an evidence pack? Prikhodko & Partners offers both, built by lawyers. A consultant’s source-of-funds report may be enough when no legal dispute exists.

What will they ask you for? A password, a 2FA code or a promised unfreeze is the clearest scam warning sign. Walk away from it.

Who sets the timeline? Binance does. No firm can speed up its review, so treat any promised date as a red flag.

Before paying anyone, write down what Binance actually asked for and in which channel. A firm that cannot work from that has not read your case.
