What Solidus saw on Hyperliquid
Solidus Labs shared a granular look at early March trading on Hyperliquid, right as oil was swinging hard. The firm says two accounts repeatedly posted large orders in one direction, pulled them, and at nearly the same time took trades in the other direction - a pattern it says resembled spoofing, a manipulation tactic.
Across 31 alerts, Solidus notes a cadence where cancellations hit one side of the order book while fills landed on the other. Tallying it up, the firm estimates that for approximately every $30 of scrapped orders on one side, about $1 of actual executions showed up on the other. By its count, the same trader was behind more than nine tenths of all cancellations in that market.
Speaking on the record, Spiro Antonopoulos - who serves as Solidus's senior vice president and its global lead for government and investigations - said, "One account rapidly placing and canceling massive volumes of orders on one side of the book while trading on the other looks like classic spoofing." He added that establishing intent would require deeper follow-through over time and following the money.
The timeline, the prices, and the mechanics
The accounts were busiest over three days beginning March 8, a stretch when oil rallied on fears tied to the Strait of Hormuz and volatility spiked on war headlines. Solidus says comments from US President Donald Trump as well as other leaders made the next day one of the most volatile on record.
Solidus estimates the trader's take was about $119,000 during March 8 to March 10 - tiny next to the notional size moving through the book. One sequence on the evening of March 9 stands out: roughly $17 million of sell orders were yanked and $425,000 of buys were completed in quick order. The Brent perpetual price slid from $83.06 to $81.42 during the roughly 10 seconds around the cancellations, then rebounded to $83.51 within five seconds and kept climbing to $87.56 inside a minute.
Most of the activity centered on contracts tracking Brent crude, with some spillover to instruments referencing West Texas Intermediate and natural gas. Solidus - launched in 2018 by veterans of Goldman Sachs - believes the trader looked like a professional, high-speed liquidity provider given the pace and size. According to Solidus, the two main wallets involved have, over their history on Hyperliquid, amassed $93 billion of notional trading volume - a measure that reflects the total value of trades executed rather than the amount of capital put at risk.
Platform design, guardrails, and the growing overlap with Wall Street
Perpetual futures - perps - are always-on derivatives that never expire and run on blockchain rails, mirroring everything from equities and indexes to oil and metals. Over the past year, Hyperliquid has raced from crypto fringe to a venue where traders speculate and hedge alongside giants like CME Group and Intercontinental Exchange. The venue is a decentralized exchange that mostly sits beyond U.S. jurisdiction; its developer is based in Singapore, and Hyperliquid lacks a formal headquarters as well as regulatory licenses.
Hyperliquid Labs' spokesperson, representing the platform's lead developer, emphasized transparency: "Every order, cancellation, and trade on the Hyperliquid blockchain is recorded on an immutable, transparent public ledger that can be reviewed in real time by anyone, including market participants and regulators." The spokesperson added, "This structural openness allows independent scrutiny of on-chain activity without reliance on any single operator to collect, disclose, analyze, or process data."

Trade.xyz, which designed the three perps in question and listed the oil contracts used, says its markets are built to "resist manipulation" by order placement. The firm pointed to Hyperliquid's order limits - a feature borrowed from traditional exchanges - together with outside data sources that feed how its perps are priced, and said it "maintains ongoing monitoring and alerting across its markets."
Some of those guardrails may have been at work. On Hyperliquid, an account's ability to submit orders is linked to how much it actually gets filled, so users who place far more than they trade can be slowed down. Even so, the episode shows how a new venue for perps is not only competing with established markets, but could create fresh avenues for rule-bending.
Spoofing has been illegal in the US for years, and major exchange operators have been pressing regulators to clamp down on Hyperliquid. CME Group and ICE have warned that activity on the platform could skew global oil benchmarks and heighten manipulation risk. As Vanderbilt Law professor Yesha Yadav put it, "Because these platforms are meant to exclude US actors, they could be seen as a lacuna in market design." She also noted the flip side - because the contract is illiquid, spotting odd behavior might actually be simpler.
Why it matters for your portfolio
In plain English: the oil-linked perps on Hyperliquid moved fast and in size, and yet the reported profit - about $119,000 over three days - sat on top of vastly larger notional flows. That combination of leverage, liquidity pockets, and 24-7 trading is exactly where sharp swings can show up before traditional markets open.
Hyperliquid's rise means crypto-native venues are now part of the backdrop for energy exposure and hedges. Perps have also been useful when other markets are shut, especially during geopolitical shocks like the Iran war. The bottom line: whether you hold energy equities, trade oil ETFs, or watch benchmark futures, episodes like this are a reminder to factor in on-chain venues that can react first and move quickly - and to track how surveillance and safeguards evolve on platforms that sit outside the usual regulatory perimeter.
Antonopoulos said the incident underscores "the novel market integrity questions facing regulators and operators" as commodity trading goes always-on and open. His question for market participants routing orders to these venues: do they have the surveillance coverage to see this kind of behavior, given their duty to monitor activity?
