Cryptocurrency Preliminary Injunctions | Court-Ordered Protection for Digital Assets During Litigation
Written by Liam Murphy, Esq. | Last reviewed July 2026
Crypto litigation can take a year or more to reach judgment. Digital assets can vanish in an afternoon. A preliminary injunction closes that gap: it is a court order that preserves the status quo for the duration of the case, so that whatever you win at the end still exists to be collected. In cryptocurrency disputes, where the assets at stake are liquid, borderless, and easy to conceal, injunctive relief is often the backbone of the entire litigation strategy.

What is a cryptocurrency preliminary injunction? A cryptocurrency preliminary injunction is a court order, issued after notice and a hearing, that prohibits a party from transferring, dissipating, or concealing digital assets, or requires other conduct, while a lawsuit proceeds. Unlike a temporary restraining order, it can remain in effect through trial.
Murphy’s Law builds injunction applications the way courts want to see them: precise claims, sworn evidence, and blockchain tracing that connects the disputed assets to specific wallets and accounts. Request a confidential consultation to discuss whether injunctive relief fits your dispute.
Preliminary Injunction vs. Temporary Restraining Order
| Temporary restraining order | Preliminary injunction | |
|---|---|---|
| Purpose | Emergency stopgap | Preserves the status quo for the life of the case |
| Timing | Obtainable within days | After notice and a hearing |
| Notice to the other side | Sometimes none (ex parte) | Always required |
| Evidentiary record | Verified complaint and declarations | Fuller record, possible live testimony |
| Duration | Generally 14 days unless extended | Until final judgment unless modified |
| Appealable | Generally not | Yes, immediately in federal court |
Both are forms of injunctive relief under Rule 65 of the Federal Rules of Civil Procedure, and courts evaluate them using essentially the same factors. The difference is timing and durability. A temporary restraining order is the emergency stopgap: obtainable within days, sometimes without notice to the other side, and generally expiring within 14 days. A preliminary injunction is the main event. It issues only after the defendant has notice and an opportunity to be heard, it rests on a fuller evidentiary record, and it can stay in force until final judgment. In crypto cases the two typically work in sequence: the TRO holds the assets in place, and the preliminary injunction hearing decides whether they stay held for the life of the case.
When to Seek Preliminary Injunctive Relief
Injunctions appear across the full range of digital asset disputes:
Fraud and theft
Continue restraining traced assets after a TRO
Ownership disputes
Wallets, tokens, or accounts that one side may liquidate
Corporate control
Partnership, joint venture, and corporate control fights involving treasury assets
Platform disputes
Disputes with platforms or projects over locked, frozen, or misdirected funds
Confidential information
Misappropriation of confidential information, code, or trade secrets by insiders
Dissipation risk
Preventing dissipation of funds by defendants facing large claims on equitable theories
The Four Factors Courts Consider
Under the standard articulated by the Supreme Court in Winter v. Natural Resources Defense Council, a plaintiff seeking a preliminary injunction in federal court must generally establish four things. The precise formulation varies by circuit and by state court, so treat this as the general framework rather than the rule of any particular courtroom.
1. Likelihood of Success on the Merits
The court previews the strength of your claims. In crypto cases this is where blockchain evidence earns its keep: a tracing record showing your assets moving into the defendant’s wallets can make fraud, conversion, and unjust enrichment claims concrete rather than conjectural.
2. Irreparable Harm
You must show injury that money damages at the end of the case cannot fix. Courts do not treat crypto as automatically irreparable; the volatility or transferability of digital assets, standing alone, has been held insufficient. What moves courts is evidence of actual dissipation risk: assets already moving through mixers or bridges, defendants who are anonymous or offshore, or a judgment that would plainly be uncollectible. Building that record is a core part of our preparation.
3. Balance of Equities
The court weighs the harm to you if relief is denied against the harm to the defendant if it is granted. Narrowly tailored orders that restrain only the traced, disputed assets fare far better than requests to freeze everything a defendant owns.
4. Public Interest
Courts consider whether the order serves broader interests. Preventing fraud and preserving the ability of courts to grant effective relief generally weigh in favor of properly supported applications.

A Crypto-Specific Wrinkle: The Type of Claim Matters
Federal courts generally cannot freeze a defendant’s assets merely to secure a potential money judgment. But when a plaintiff asserts equitable claims to specific, traceable property, such as a constructive trust, conversion, or unjust enrichment over identified crypto, courts have far more latitude to restrain those particular assets. Because cryptocurrency is traceable on-chain in a way cash is not, well-pleaded crypto cases are often strong candidates for this kind of targeted relief. Pleading the case correctly from day one is therefore not a formality. It can determine whether a freeze is legally available at all.
Evidence and the Injunction Hearing
A preliminary injunction motion is decided on evidence, not argument. The record typically includes sworn declarations from the client and investigators, complete transaction histories and tracing exhibits, exchange and bank records obtained through expedited discovery, communications with the defendant, and, where useful, expert analysis explaining the on-chain evidence to the court. Courts may hold an evidentiary hearing with live testimony, particularly where key facts are disputed. Because the defendant appears and contests the motion, expect the tracing methodology and the irreparable harm showing to be attacked. Applications prepared for that fight succeed; applications prepared as paperwork do not.
- Sworn declarations from the client and investigators
- Complete transaction histories and tracing exhibits
- Exchange and bank records obtained through expedited discovery
- Communications with the defendant
- Expert analysis explaining the on-chain evidence
Bond, Duration, Enforcement, and Appeal
Rule 65(c) requires security in an amount the court considers proper to protect a wrongfully enjoined defendant, and the amount is within the court’s discretion. Once issued, a preliminary injunction generally remains in effect until final judgment unless modified or dissolved, and it binds the parties and those acting in concert with them who receive notice, which is how orders reach exchanges holding restrained accounts. Violations are punishable as contempt. Preliminary injunction rulings are also immediately appealable in federal court, so both sides should expect the possibility of appellate review, and either party may later move to modify or dissolve the order as circumstances change.

The Hard Cases: Decentralization, Anonymity, and Offshore Defendants
Injunctions bind people, not protocols. A smart contract will not obey a court order, a decentralized exchange has no compliance desk to serve, and a pseudonymous defendant holding keys in self-custody may simply defy the court from abroad. These limits are real, and any lawyer who does not acknowledge them is not being straight with you. The practical response is target selection: direct relief at the reachable points, such as centralized exchanges, stablecoin issuers capable of freezing tokens at the contract level, domestic defendants, and identifiable intermediaries, while using the litigation to convert anonymous defendants into named ones. Courts have shown continued willingness to apply traditional equitable tools to digital assets when applications respect these realities.
Where relief is most effective
- Centralized exchanges
- Stablecoin issuers able to freeze tokens at the contract level
- Domestic defendants
- Identifiable intermediaries
Where it is not
- Smart contracts and decentralized protocols
- Pseudonymous self-custody wallets held abroad

Frequently Asked Questions
What is the difference between a TRO and a preliminary injunction?
A TRO is emergency relief: fast, short-lived, and sometimes granted without notice to the other side. A preliminary injunction issues only after the defendant has notice and a chance to oppose, rests on a fuller evidentiary record, and can remain in effect through final judgment. In most crypto asset cases, the TRO preserves the assets long enough for the court to decide the preliminary injunction motion.
How long does a preliminary injunction last?
Generally until the case ends, whether by judgment, settlement, or dismissal, unless the court modifies or dissolves it earlier. That durability is what makes it so valuable in crypto disputes: it keeps the assets in place through discovery, motions, and trial, which can take a year or longer.
Is a hearing always required?
The defendant must receive notice and an opportunity to be heard before a preliminary injunction issues. Whether the court holds a live evidentiary hearing with testimony, as opposed to deciding on written declarations and argument, depends on the court and on whether material facts are genuinely disputed. Crypto cases with contested tracing often warrant evidentiary hearings.
Do I have to post a bond?
Federal Rule 65(c) requires security in an amount the court considers proper, and many state courts have similar requirements. The amount is discretionary and depends on the potential harm to the enjoined party. Courts sometimes set modest bonds where the restrained assets are alleged to be the plaintiff’s own stolen property, but this varies by judge and jurisdiction.
Can a preliminary injunction reach assets held overseas?
Sometimes. An injunction binds parties over whom the court has jurisdiction, wherever their assets sit, and a defendant who moves restrained assets abroad risks contempt. As a practical matter, enforcement against foreign platforms and anonymous actors is harder, and relief is most effective against defendants and institutions with U.S. presence or exposure. Jurisdictional reach is assessed case by case.
What happens if the defendant violates the injunction?
Violations are punishable as contempt of court, which can mean fines, adverse rulings in the case, and, for serious defiance, arrest. Violations also tend to devastate a defendant’s credibility with the court. Where assets were moved in violation of an order, the tracing continues and the order can be enforced against recipients acting in concert with the defendant who had notice of it.
Can an injunction be appealed or changed?
Yes. Orders granting or denying preliminary injunctions are immediately appealable in federal court, and either party can move to modify or dissolve an injunction as facts develop. Well-supported, narrowly tailored orders are the ones that survive this scrutiny, which is why we build the record carefully from the start.
