Lawsuit filedCrypto Theft and Exchange Hack Lawsuits: Coinbase, Bybit, FTX, and Your Options
Filed: Coinbase breach suits, the FTX MDL, and arbitration awards show paths to recover stolen crypto. See who may qualify after an exchange hack or theft.

You may be able to recover stolen crypto by suing or arbitrating against the exchange that held it, if the exchange's security failures made the theft possible. As of September 2026, proposed class actions over Coinbase's May 2025 data breach are pending, the FTX collapse litigation continues in federal court in Miami, and some individual account takeover victims have won arbitration awards.
Results depend heavily on your user agreement and your evidence. Save every transaction ID and support ticket, report the theft, and get a free case review.
Key takeaways.
- Crypto theft lawsuits usually allege the exchange failed to protect accounts or data, not that it stole the funds itself.
- Coinbase told investors in May 2025 that a breach involving bribed overseas support staff could cost it between $180 million and $400 million, and said it would reimburse customers tricked into sending funds to the attackers.
- Most exchange user agreements require individual arbitration, and some victims have won there, including a $618,000 award against Coinbase reported in December 2025.
- FTX customers recover mainly through the bankruptcy distributions, while MDL No. 3076 pursues outside firms and promoters.
- Hackers behind state-sponsored thefts like the $1.5 billion Bybit hack are rarely reachable in U.S. court, so claims focus on the platform.
You may qualify if.
- Crypto was taken from your exchange account through an account takeover, SIM swap, or support-staff compromise.
- You were a Coinbase customer notified that your data was exposed in the May 2025 breach, especially if you were later targeted by impostor scams.
- You held assets on FTX when it collapsed in November 2022, or were harmed by others alleged to have helped FTX.
- The exchange ignored your reports, froze your account while funds drained, or refused to reimburse you despite its own security promises.
- Your loss happened recently enough to fit your state's deadline and any deadline in the exchange's user agreement.
What to gather.
- 1Transaction IDs and wallet addresses showing where your crypto went, with timestamps.
- 2Screenshots of your account history, security alerts, and login notifications.
- 3Every email, chat, and ticket with the exchange's support team, including breach notices.
- 4Phone carrier records if a SIM swap was involved, and any police or FBI IC3 report numbers.
- 5Your exchange user agreement version and records of the account's value on the date of the theft.
What crypto theft and exchange hack lawsuits are about
Crypto theft cases come in three main types:
- Account takeovers. Someone gets into your exchange account through a stolen password, a SIM swap that hijacks your text codes, or a fake support call, and moves your crypto out. Claims argue the exchange's security, alerts, or response fell short.
- Exchange data breaches. Customer data leaks, and criminals use it to run convincing impostor scams. Claims argue the exchange failed to protect data it promised to guard.
- Exchange failures and hacks. The platform itself is hacked or collapses, and customers cannot withdraw.
Coinbase
In May 2025, Coinbase disclosed that criminals had paid contractors and employees working in support roles outside the U.S. to pull customer information from internal systems. The stolen data included names, addresses, phone numbers, and emails, and Coinbase said login credentials and passwords were not taken. Coinbase refused a $20 million ransom demand and said it would reimburse customers who were tricked into sending funds to the attackers. In its filing with regulators, it estimated remediation and reimbursement costs of $180 million to $400 million.
Proposed class actions followed quickly. One law firm filed a complaint in the U.S. District Court for the Northern District of California on the day of the disclosure, alleging Coinbase failed to protect customers' personal information. Coinbase disputes these claims, and none has been proven.
Coinbase customers have also brought individual claims. In December 2025, an American Arbitration Association panel awarded a Coinbase customer $618,000 in damages and costs after a 2024 account takeover, according to InvestmentNews.
SIM swaps and phone carriers
Many account takeovers start not at the exchange but at the phone company. In a SIM swap, a criminal convinces or bribes a carrier employee to move your phone number to a SIM card they control, then uses the text message codes to reset your exchange password. Victims have sued carriers as well as exchanges, arguing that the carrier failed to verify the person requesting the change. If your phone suddenly lost service shortly before your crypto disappeared, ask your carrier for the account change records right away; they are often the most important evidence in the case.
Bybit
On February 26, 2025, the FBI announced that North Korea was responsible for the theft of about $1.5 billion in virtual assets from the Bybit exchange on or about February 21, 2025, activity the FBI calls "TraderTraitor." State-sponsored hackers are effectively beyond the reach of U.S. civil courts, so claims arising from hacks like this focus on the platform's responsibilities to its customers and on freezing and tracing stolen assets.
FTX
After FTX collapsed in November 2022, customer lawsuits against insiders, promoters, and professional firms were centralized as In re FTX Cryptocurrency Exchange Collapse Litigation, MDL No. 3076, in the U.S. District Court for the Southern District of Florida. In May 2026, the law firm Fenwick & West, which advised FTX, agreed to pay $54 million to settle claims brought by former FTX customers, subject to court approval. Fenwick denies wrongdoing.
Where crypto theft cases stand now
- Coinbase breach suits: pending as proposed class actions. Coinbase's user agreement contains an arbitration clause, so whether customers can proceed as a class in court is a central fight in cases like these.
- FTX: the MDL continues in Miami against third parties, while the bankruptcy estate pays customers directly. The FTX Recovery Trust began its fifth distribution, about $900 million, on July 31, 2026, bringing cumulative recoveries for U.S. and international customer claims to 105% of their allowed amounts under the plan. Those amounts are based on crypto values on the November 2022 bankruptcy date, not today's prices.
- Bybit: recovery efforts center on tracing and freezing stolen assets rather than U.S. consumer lawsuits.
- Individual arbitration: ongoing across exchanges, and usually private, so outcomes rarely become public.
Arbitration shapes almost every exchange case. When many customers file individual arbitration claims at once, the exchange usually has to pay most of the filing fees for each one, which can push it toward settlement. On the other hand, an arbitration award does not create precedent for anyone else, and arbitrators' reasoning is rarely published. That is why the handful of public awards, like the $618,000 Coinbase decision, get so much attention: they are some of the only visible signals of how these claims are being valued.
Who may qualify for a crypto theft claim
Your case is stronger if:
- The platform had a role. Its data leaked, its support staff were compromised, it ignored alerts or your calls, or its security settings did not work as promised.
- You acted quickly. You reported the theft promptly and asked the exchange to freeze the account.
- You can trace the funds. Blockchain records showing where your assets went help prove what was taken and when.
- The loss is meaningful. Arbitration and litigation take time; larger losses justify the effort more easily.
Who probably does not qualify: people who gave their seed phrase or password to a scammer with no involvement by the exchange, people who sent crypto voluntarily in an investment scam, and people who held assets in a self-custody wallet that was compromised on their own device. Those losses are real, but there is usually no platform to hold responsible. Report them to the FBI's Internet Crime Complaint Center and your local police anyway.
Timing matters in account takeover cases. Exchanges often point to their user agreement to argue that customers are responsible for losses caused by compromised credentials. Your strongest facts are usually the ones showing the exchange had a chance to stop the theft: unusual logins it did not flag, a withdrawal to a new address with no added verification, a support call that went unanswered while funds were moving, or a breach of the exchange's own systems that handed criminals your details.
If you received a Coinbase breach notice but lost nothing, you may still be a member of a proposed class, though data-only claims usually produce small payments. See how much a data breach settlement is worth.
What crypto theft claims can recover
There are no statutory damages specific to crypto theft. Recoveries come from ordinary legal claims:
| Claim | What it can recover |
|---|---|
| Negligence | The value of stolen assets and related losses |
| Breach of contract | Losses caused by broken security or service promises |
| State consumer protection law | Damages, sometimes multiplied, plus fees in some states |
| Data breach laws | Varies; some states allow statutory damages for breaches |
Real results vary widely. The $618,000 Coinbase arbitration award shows an individual can recover a full loss plus costs. Data breach class settlements, by contrast, often pay modest amounts per person unless a class member can document an out-of-pocket loss. FTX customers are receiving their recoveries through the bankruptcy, not through the MDL.
How assets are valued matters. A claim may be measured by the value on the date of theft, not today's price, which can cut either way. Keep a record of the market price at the time of each unauthorized transfer, and of any fees or tax consequences that followed, so a lawyer can present a complete damages figure.
The legal theories behind exchange lawsuits
- Duty to protect data and accounts. Exchanges hold customer identity documents and funds. Plaintiffs argue that creates a duty of reasonable security, especially against known threats like insider bribery and SIM swaps.
- Contract terms. User agreements set out security features and often limit the exchange's liability. Courts and arbitrators look closely at whether a limitation is enforceable.
- Arbitration and class waivers. Most exchange agreements require individual arbitration and include a class action waiver. That can block a class case but also gives individual victims a faster, private forum.
- State privacy and breach statutes. Some states, such as California, allow statutory damages when a business's failure to maintain reasonable security leads to a breach of certain personal information.
Criminal cases against hackers can lead to forfeiture of seized assets, and victims can sometimes seek restitution there. Those processes are separate from any civil claim against the exchange.
Deadlines for crypto theft claims
Deadlines depend on the claim, the state, and your user agreement:
- State statutes of limitations for negligence and contract claims typically range from about 2 years to 6 years.
- User agreements may require you to give the exchange written notice and try informal resolution before filing arbitration, with a set waiting period.
- Bankruptcy claims such as FTX have their own bar dates that have long passed for most customers.
Because exchange agreements often require a notice and waiting period before arbitration, starting the process early protects your deadline. A statute of limitations generally keeps running while you go back and forth with support tickets.
What to do now if your crypto was stolen
- Lock everything down. Change passwords, move remaining assets, remove SMS as a two-factor method, and add a carrier PIN or port-out lock.
- Report it. File with the exchange, the FBI's Internet Crime Complaint Center, and local police. Keep the report numbers.
- Preserve the trail. Download transaction histories, save support chats, and record the wallet addresses that received your funds.
- Beware of "recovery" services. People who promise to recover stolen crypto for an upfront fee are a common second scam. See how to spot settlement and recovery scams.
- Find your user agreement. The version in effect when you opened or last used the account controls arbitration and notice rules.
- Talk to an attorney. Independent attorneys who handle exchange and data breach cases can tell you whether you belong in a pending class case or should pursue arbitration.
The claims in pending cases against Coinbase and others are allegations until decided. If an exchange's failure cost you crypto, a free case review takes about two minutes. For breach notices more generally, read what to do after a data breach notice, and see our data breach lawsuit page.

Crypto theft and exchange hacks: common questions.
Can I sue Coinbase if my crypto was stolen?
Possibly. If Coinbase's security or support failures contributed to the theft, you may have a claim for negligence or breach of contract. Coinbase's user agreement generally requires individual arbitration, and at least one customer won a $618,000 arbitration award in 2025 after an account takeover.
Is there a Coinbase data breach class action?
Yes. Proposed class actions were filed after Coinbase disclosed in May 2025 that bribed overseas support staff had accessed customer data. As of September 2026 they are pending and unproven, and Coinbase's arbitration clause is a key issue in whether they can proceed as class cases.
How do I get my stolen crypto back?
Report the theft to the exchange, the FBI's Internet Crime Complaint Center, and local police right away, and ask the exchange to freeze any related accounts. If the exchange's failures played a role, a lawyer can evaluate a claim against it. Avoid any service that charges upfront to recover crypto.
Will FTX customers get their money back?
Most FTX customers are being repaid through the bankruptcy. After the fifth distribution that began on July 31, 2026, U.S. and international customer claims had received a cumulative 105% of their allowed amounts, measured at November 2022 values. Separate lawsuits in MDL No. 3076 pursue outside firms and promoters.
Can I sue the hackers who stole my crypto?
In theory yes, but hackers are usually anonymous or overseas. In the $1.5 billion Bybit theft, the FBI attributed the attack to North Korea. That is why most civil claims focus on the exchange or other companies whose failures made the theft possible.
Does my exchange have to reimburse me for a hack?
It depends on your user agreement, what caused the loss, and state law. Some exchanges reimburse certain losses voluntarily, as Coinbase said it would for customers tricked through its 2025 breach. Others dispute responsibility, which is when arbitration or litigation comes in.
