Robinhood Engineers Charged With Crypto Insider Trading: What the Hyperliquid Case Means for Federal Crypto Investigations
Federal prosecutors in Manhattan have charged two Robinhood engineers with commodities fraud and wire fraud for allegedly using confidential information about upcoming Robinhood Crypto listings to trade cryptocurrency perpetual futures on Hyperliquid.
The cases are United States v. Hefu Chai, 26 MAG 3716, and United States v. Huaisong Xiang, a/k/a “Jerry Xiang,” 26 MAG 3718, filed in the U.S. District Court for the Southern District of New York.
The allegations are significant for anyone working or trading in cryptocurrency.
This is not a traditional insider-trading prosecution involving corporate stock. According to the government, confidential information concerning crypto listings at one company was allegedly monetized through derivative positions on a decentralized crypto trading platform.
The defendants have been charged, not convicted. The allegations in the criminal complaints have not been proven, and both defendants are presumed innocent unless and until proven guilty.
What does the DOJ allege happened at Robinhood?
Hefu Chai and Huaisong Xiang were engineers at Robinhood who worked on the listing of new digital assets on Robinhood Crypto.
According to the complaints, Robinhood limited sensitive information concerning upcoming cryptocurrency listings to employees designated as “Coin Aware Individuals.” Those employees had access to a private Slack channel containing information concerning listing dates, planning, readiness and launches.
The complaints allege that Robinhood's policies prohibited employees from trading securities, crypto assets, event contracts, or other financial instruments while possessing material nonpublic information obtained through their employment. Coin Aware Individuals were also allegedly prohibited from trading on Robinhood or another platformbefore and for 24 hours following Robinhood's public announcement of a listing or delisting.
That detail is important.
The government's theory is not limited to an employee purchasing the cryptocurrency that his employer is preparing to list.
Prosecutors allege the defendants instead used the information to trade perpetual futures on Hyperliquid.
What are the criminal charges?
Each defendant is charged with:
Commodities fraud, under provisions of the Commodity Exchange Act and CFTC Rule 180.1; and
Wire fraud, under 18 U.S.C. § 1343.
The complaints allege that each defendant obtained material nonpublic information in breach of a duty and used that information to trade perpetual futures for personal gain. The wire-fraud counts separately allege misuse of confidential business information to obtain money or property from trading counterparties.
According to DOJ, a violation of the Commodity Exchange Act charged here carries a statutory maximum of 10 years' imprisonment, while wire fraud carries a statutory maximum of 20 years. Those are statutory maximums, not predictions of the sentence either defendant would receive if convicted.
Why are the Hyperliquid trades important?
The government's allegations illustrate how federal crypto investigations are evolving.
The alleged confidential information originated at Robinhood.
The alleged trades occurred on Hyperliquid.
And the instruments allegedly traded were perpetual futures tied to cryptocurrency tokens, rather than ownership of the underlying tokens themselves.
Perpetual futures allow traders to obtain economic exposure to changes in an asset's price without owning that asset. The complaints also note that perpetual positions can be purchased on margin, allowing a trader to obtain substantial exposure with comparatively less capital.
This means that a federal investigation into alleged misuse of confidential crypto information does not necessarily end with an examination of whether someone bought or sold the underlying token.
Investigators may examine derivatives positions, decentralized trading platforms, wallet activity, exchange accounts, transfers between wallets, workplace communications and the timing of public announcements.
The government's evidence is remarkably onchain
One of the most important aspects of the Chai complaint is how prosecutors say they connected traditional investigative evidence with blockchain activity.
The FBI alleges that three Hyperliquid wallets were connected to Chai through transactions involving a cryptocurrency exchange account registered in his name. The complaint then compares activity in those wallets with confidential Robinhood listing information and subsequent public listing announcements.
For example, prosecutors allege that Chai learned through Robinhood's private Slack channel that the company planned to list MEW and MOODENG. The government says a wallet attributed to Chai subsequently opened long perpetual positions in those assets on Hyperliquid before Robinhood publicly announced the listings. The complaint describes additional alleged trades involving ASTER, XPL, HYPE, ENA, AERO, SYRUP, LDO, DOT and LIT. Prosecutors allege at least ten instances of advance trading and more than $50,000 in profits.
The Xiang complaint describes a similar investigative method.
Among other allegations, the FBI says Xiang received confidential information concerning Robinhood's planned POPCAT listing, transferred approximately 18 ETH worth about $34,000 to a Hyperliquid wallet, and subsequently opened long POPCAT perpetual positions. The complaint alleges at least ten additional occasions of advance trading and identifies examples involving MEW, MOODENG, ONDO and RENDER. Prosecutors likewise allege more than $50,000 in profits.
Again, these are government allegations—not established facts.
But from a criminal-defense perspective, the investigative architecture matters.
Crypto transactions being “onchain” does not make a trader anonymous
This case provides another reminder that pseudonymous blockchain activity should not be confused with anonymity.
The Chai complaint describes investigators following transfers between an exchange account and three blockchain wallets. The Xiang complaint similarly identifies an exchange account registered in Xiang's name and traces ETH from that account to a Hyperliquid wallet that prosecutors associate with the alleged trades.
That type of investigation can combine:
blockchain records + centralized exchange records + KYC information + workplace communications + IP/device evidence + financial records + transaction timing.
The blockchain may therefore become part of the government's evidentiary trail rather than an obstacle to identifying the trader.
For a person who becomes the subject or target of a federal cryptocurrency investigation, this has an important practical consequence: the government may have reconstructed substantial portions of the transaction history before making contact with the person being investigated.
The one-hour window may be one of the most interesting allegations
The complaints contain another detail worth watching.
According to the FBI, a digital asset could typically become available for trading on Robinhood Crypto up to approximately one hour before Robinhood publicly announced the listing. The government alleges that price pressure could begin once trading became available, even before the public announcement.
Prosecutors say this explains why some allegedly profitable Hyperliquid positions were closed before Robinhood made its public announcement.
That allegation illustrates a difficult issue increasingly likely to arise in crypto markets:
When exactly does information stop being nonpublic?
Is it when a company posts an announcement?
When an API changes?
When the token becomes technically tradable?
When blockchain activity makes an event observable?
When sophisticated traders or bots can infer what is occurring?
The complaints do not resolve every version of that question. But they demonstrate why timing evidence can become central to a federal crypto fraud investigation.
DOJ is signaling that derivatives do not create an escape hatch
The Southern District of New York made its enforcement position unusually explicit when announcing the charges.
U.S. Attorney Jamie McDonald stated that corporate insiders cannot evade securities and commodities laws by using misappropriated information to trade derivatives such as “perpetual futures, tokenized securities, or other similar financial instruments.”
Importantly, the Robinhood complaints concern perpetual futures. They do not allege that these defendants traded tokenized securities.
The reference to tokenized securities came from the U.S. Attorney when describing the broader enforcement principle DOJ believes applies.
That distinction matters.
It also indicates where federal prosecutors believe this area of law is heading as traditional financial exposure increasingly moves onto blockchain infrastructure.
What should someone do if contacted about a federal crypto investigation?
A person contacted by the FBI, DOJ, CFTC, SEC or another federal agency about cryptocurrency trading should treat the contact seriously—even if the person believes the trading was lawful.
The early stages of a federal investigation can involve questions about wallet ownership, exchange accounts, Telegram or Signal communications, employer information, VPN usage, trading strategies, tax records and the source of funds.
Statements made during that process can become evidence.
Deleting messages, altering records, moving assets to conceal them, destroying devices or attempting to coordinate accounts with other people can create additional problems and should not be used as a substitute for obtaining legal advice.
A federal criminal defense attorney familiar with cryptocurrency can instead evaluate the government's legal theory, determine what evidence may exist, preserve relevant records and address communications with investigators.
Crypto criminal cases increasingly require two kinds of fluency
I have practiced criminal defense for more than 25 years.
I originally entered cryptocurrency as a trader and investor. Over time, that developed into a substantial part of my legal work and my coverage of cryptocurrency enforcement.
Through Lex Line, I followed major federal crypto prosecutions, and I attended proceedings in Manhattan in both the Nathaniel Chastain/OpenSea insider-trading prosecution and the Sam Bankman-Fried criminal trial.
Cases like the new Robinhood prosecutions demonstrate why crypto criminal defense increasingly requires understanding both sides of the case:
Federal criminal law and procedure on one side.
Wallets, exchanges, DeFi protocols, perpetual futures and blockchain evidence on the other.
The government is becoming increasingly sophisticated about connecting those worlds.
Defense counsel needs to understand them as well.

Frequently Asked Questions About Federal Crypto Insider Trading Investigations
Can you be charged with insider trading for cryptocurrency?
Yes, depending on the facts and the government's legal theory. Federal prosecutors have pursued alleged misuse of confidential cryptocurrency information through statutes including wire fraud and commodities fraud. In the Robinhood cases, prosecutors charged commodities fraud and wire fraud based on allegations that employees used confidential information about upcoming crypto listings to trade perpetual futures.
Importantly, “insider trading” is often a descriptive term rather than the formal title of the criminal charge. The precise statutes and elements depend on the asset, instrument, conduct, and government's theory.
What are the charges against the Robinhood employees?
Federal prosecutors in the Southern District of New York charged Robinhood engineers Hefu Chai and Huaisong Xiang, also known as Jerry Xiang, with commodities fraud and wire fraud.
The government alleges that they had confidential information concerning upcoming Robinhood Crypto listings and used that information to trade cryptocurrency perpetual futures on Hyperliquid before Robinhood publicly announced the listings.
The allegations have not been proven, and both defendants are presumed innocent unless and until proven guilty.
What is crypto listing information, and why can it matter in a criminal case?
A major exchange or brokerage listing can affect demand and trading activity for a cryptocurrency. Information that a platform intends to list a particular asset may therefore have significant economic value before the decision becomes public.
According to the Robinhood complaints, certain employees with access to upcoming listings were designated “Coin Aware Individuals.” Robinhood allegedly imposed restrictions on how those employees could trade while possessing confidential listing information.
Whether particular information is actually material and nonpublic, whether a defendant possessed it, what duties applied, and whether the information was used in a particular trade can become important issues in a criminal case.
Can trading crypto perpetual futures lead to federal criminal charges?
Yes. The Robinhood prosecutions demonstrate that federal authorities may investigate trading in crypto perpetual futures, not merely purchases and sales of the underlying cryptocurrency.
The government alleges that the defendants used confidential Robinhood listing information to take positions in perpetual futures on Hyperliquid. DOJ charged the alleged conduct under federal commodities-fraud and wire-fraud laws.
Can you be investigated for trading on Hyperliquid?
Yes. Trading through a decentralized or onchain platform does not prevent federal investigators from examining the activity.
In the Robinhood cases, the FBI allegedly reconstructed Hyperliquid trading activity using blockchain transactions and other evidence. The complaints describe investigators connecting wallets to centralized cryptocurrency exchange accounts and then comparing trading activity with confidential Robinhood information and listing dates.
Use of Hyperliquid by itself does not establish criminal conduct. The relevant issue in these prosecutions is the government's allegation that confidential information was improperly used to make particular trades.
Are crypto wallets anonymous to the FBI?
A blockchain address may be pseudonymous, but that does not necessarily make the person controlling it anonymous.
Federal investigators can potentially combine public blockchain records with centralized-exchange KYC records, bank records, device or IP evidence, employer records, communications, subpoenas and other investigative evidence.
The Robinhood complaints illustrate this process: prosecutors describe tracing transactions between exchange accounts associated with the defendants and wallets allegedly used to trade on Hyperliquid.
Can the FBI trace transactions from Coinbase, Kraken or Robinhood to a self-custody wallet?
Potentially, yes. A transfer from a KYC exchange account to a blockchain address can become one piece of evidence investigators use to attribute a wallet to an individual.
Wallet attribution is nevertheless an evidentiary question. A blockchain transaction may establish that assets moved between addresses, but questions can remain about who actually controlled a wallet, who authorized a transaction, who possessed a device or private key, and what the person knew or intended at the time.
Those distinctions can matter substantially in a criminal defense investigation.
Is it illegal to trade a cryptocurrency before Robinhood or another exchange lists it?
Not automatically.
Simply buying a cryptocurrency before an exchange announces a listing is not, by itself, what prosecutors allege was criminal in these cases. The Robinhood complaints focus on the alleged use of confidential information obtained through employment to make trades for personal gain.
That distinction is important. A trader acting on public information, market research or independent analysis presents a very different factual situation from an employee accused of misappropriating confidential employer information.
When does crypto listing information become public?
That can be a complicated factual issue.
The Robinhood complaints allege that an asset could sometimes become available for trading on Robinhood Crypto before Robinhood publicly announced the listing. That creates potentially important questions about exactly when information became publicly observable and what information was available to market participants at a particular time.
In a criminal case, transaction timestamps, blockchain data, exchange records, API activity, public announcements and internal communications may therefore become important evidence.
What should I do if the FBI contacts me about cryptocurrency trading?
Do not assume that an informal request for an interview is insignificant.
You can consult an attorney before deciding whether to speak with federal investigators. A lawyer can determine what agency is investigating, attempt to identify whether you are being treated as a witness, subject or target, evaluate potential exposure, and communicate with investigators or prosecutors on your behalf.
Avoid deleting communications, destroying records, concealing assets or altering evidence. Those actions can create additional legal problems.
What should I do if I receive a federal subpoena involving crypto or blockchain transactions?
Preserve the subpoena and the potentially relevant evidence and consult qualified counsel promptly.
A cryptocurrency investigation may involve exchange records, wallet addresses, transaction histories, computers and phones, employment records, Slack or other workplace communications, Telegram or Signal messages, tax records and financial accounts.
Counsel can evaluate the subpoena's scope, preservation obligations, potential Fifth Amendment issues where applicable, and how a response should be handled.
Do I need a lawyer who understands cryptocurrency for a federal crypto investigation?
Federal criminal procedure remains federal criminal procedure, but cryptocurrency investigations can introduce an additional technical evidentiary layer.
A defense lawyer may need to understand wallet attribution, blockchain explorers, centralized exchanges, self-custody, smart contracts, DeFi protocols, perpetual futures and onchain transaction histories while also addressing traditional issues such as intent, knowledge, materiality, confidential information, search warrants, subpoenas and federal charging statutes.
That combination can be particularly important when the government's case depends on connecting an identifiable person to pseudonymous blockchain activity.
What is a federal crypto criminal defense lawyer?
A federal crypto criminal defense lawyer represents individuals and businesses facing federal investigations or prosecutions involving cryptocurrency, digital assets or blockchain transactions. These matters can include allegations involving wire fraud, commodities fraud, securities fraud, money laundering, sanctions, unlicensed money transmission, cryptocurrency insider trading, exchange activity and other digital-asset offenses.
