Abstract

Wall Street trading giant Jane Street Group is facing a lawsuit alleging it used insider information from a private Telegram channel with a former Terraform Labs intern to avoid losses and profit from the collapse of the Terra ecosystem in May 2022. According to newly unsealed court documents, Jane Street allegedly sold nearly $192 million worth of the UST stable币 before its depeg, and then established short positions, netting approximately $134 million in profits. The suit, filed by Terraform's bankruptcy estate, claims the firm gained a critical "information advantage" through these private communications, allowing it to execute large sales, including an $85 million UST transaction on Curve Finance minutes after Terraform quietly withdrew liquidity. Jane Street has denied the allegations as "baseless" and moved to dismiss the case. A 2023 court ruling that classified UST and Luna as securities bolsters the legal basis of this suit.

Deep Chao Introduction: Wall Street's top trading firm, Jane Street, is accused of using a private Telegram chat to obtain insider information before the Terra collapse, precisely exiting their position and shorting to profit $134 million. This lawsuit not only exposes the information advantage of traditional finance giants in the crypto market but also gains stronger legal footing due to a 2023 court ruling that recognized UST and Luna as securities. It holds significant reference value for investors understanding institutional behavior and market manipulation.

Jane Street Group, one of Wall Street's largest trading firms, is accused of selling $192 million worth of the TerraUSD (UST) stablecoin just before the Terra collapse in May 2022, allegedly through a private Telegram channel with Terraform Labs insiders, according to newly unsealed court filings in Manhattan federal court.

The lawsuit, brought by the administrator liquidating Terraform's bankruptcy estate, was amended last week to reduce redactions and reveal new details about how Jane Street allegedly obtained non-public information as the Terra ecosystem crumbled.

Jane Street denied the initial allegations when they were filed in February, calling them "desperate" and "baseless," and asked the court to dismiss the case.

According to the suit, Jane Street's alleged informational edge came from a private Telegram backchannel between former Terraform intern Bryce Pratt (then working at Jane Street) and his former Terraform colleagues.

The bankruptcy administrator claims this access helped Jane Street unload its UST position near its face value before the algorithmic stablecoin's implosion and then establish short positions, profiting approximately $134 million during the collapse of Terra's $40 billion ecosystem.

In one internal exchange cited in the suit, Pratt allegedly joked that colleagues should be "slightly happier" about having an "information advantage."

With that advantage, Jane Street allegedly sold its entire UST position on May 7, 2022, unloading roughly 193 million tokens. Its single largest trade was an $85 million UST sale on the decentralized exchange Curve Finance, which occurred just nine minutes after Terraform quietly withdrew $150 million in UST liquidity from the same pool.

This trade is significant because public post-mortems of Terra's collapse have long focused on a large swap on Curve that helped push the token off its $1 peg. The lawsuit now alleges that wallet belonged to Jane Street.

When a crypto analytics firm later told a Jane Street contact that the firm had "made a killing," internal communications cited in the case show traders worrying about how their wallet was identified and then discussing how to "deactivate" them.

"This lawsuit is a transparent attempt to extract money in the well-known context that losses suffered by Terra and Luna holders were the result of a multi-billion dollar fraud perpetrated by Terraform Labs management," a Jane Street spokesperson said. "As demonstrated by the motion to dismiss filed with the court last month, we will vigorously defend ourselves against these baseless, opportunistic claims."

The suit also names Jane Street co-founder Robert Granieri and trader Michael Huang. It alleges violations of federal securities laws and the Commodity Exchange Act and seeks to recover the profits to repay creditors.

A 2023 federal court ruling in a separate U.S. Securities and Exchange Commission case that found UST and Luna qualified as securities gives the new lawsuit stronger legal grounding.

The lawsuit states that on May 18, 2022, five days after UST bottomed, Jane Street offered a job to a Terraform research lead. He joined the firm two weeks later.

Raising $400 Million in Funding, Shenzhen's Embodied AI Unicorn is Heading for an IPO

LimX Dynamics, a leading Chinese humanoid robotics company based in Shenzhen, has raised nearly $4 billion in total funding following a $2 billion Pre-IPO round. This latest round, backed by prominent global investors including IDG Capital, Lens Technology, GGG Group, and Redstone VC, values the company at approximately 150 billion yuan. Founded in 2022 by Southern University of Science and Technology professor Zhang Wei, the company has developed a full-stack, self-developed "brain system" for humanoid robots. Its three-layer technical architecture (System 0 for locomotion, System 1 for specific skills, and System 2 for cognitive reasoning) powers a diverse product matrix, including the LimX Luna for commercial service and the LimX Oli R&D platform. Often compared to its American counterpart Figure, LimX Dynamics differentiates itself by focusing on "serving people, not processes" and prioritizing commercial service scenarios over factory applications first. The company has secured thousands of pre-orders, with over half coming from overseas markets, and has begun initial deliveries. With a distinctly global investor base and strategy, LimX Dynamics aims to leverage China's manufacturing advantages for worldwide competition. Having completed its shareholding reform in March 2026, the company is now steadily advancing its IPO plans, positioning itself as a key contender in the intensifying race to go public within the humanoid robotics sector.

Grayscale: The Three Evolutionary Stages of Stock Tokenization and a Rundown of Core Beneficiary Public Blockchains

Grayscale research outlines three evolutionary phases for the tokenization of equities, each benefiting different blockchain infrastructures. The first phase is the third-party "wrapper model," where a Special Purpose Vehicle (SPV) holds the underlying stock and tokenized shares represent claims on that entity. This model, accounting for over 70% of the current tokenized stock market cap, allows for DeFi integration and is prevalent on public blockchains like Ethereum, Solana, and BNB Chain. The second phase is the "entitlement model," exemplified by an upcoming pilot from the Depository Trust & Clearing Corporation (DTCC) on the Canton Network. This approach involves placing existing, regulated securities onto a blockchain for transfer within the post-trade infrastructure, without creating a new security. The third and most transformative phase is issuer-led native issuance, where companies directly issue securities on-chain. While offering the greatest long-term potential, this model requires further regulatory clarity and is seen as favoring open-architecture blockchains like Ethereum and Solana, as well as hybrid networks like Avalanche. The report concludes that all three models will likely coexist. The blockchains poised to benefit most from tokenization growth are identified as Ethereum, Solana, BNB Chain, Avalanche, and Canton Network.
