Behind the Curtain: How Justin Sun Stepped In to Save TUSD Amid Alleged $456M Misappropriation

TrueUSD (TUSD), once marketed as a fully dollar-backed stablecoin, was quietly propped up by crypto entrepreneur Justin Sun after a major portion of its reserves were rendered inaccessible due to questionable fund transfers, according to newly revealed Hong Kong court filings.

The drama unfolded after Techteryx, which acquired TUSD from TrueCoin in 2020, discovered that approximately $456 million of its reserves had been funneled into illiquid trade finance deals via a Dubai-based entity, Aria Commodities DMCC. These transfers were allegedly made without the company’s knowledge or authorization, and now lie at the center of what Techteryx describes as “a massive fraud.”

First Digital Trust (FDT), the fiduciary entrusted with managing the reserves, is accused of misdirecting the funds into investments far outside the mandate. Court documents allege that FDT’s CEO, Vincent Chok, approved the transactions and routed $15.5 million in secret commissions to a shadowy entity named “Glass Door.”

The companies involved—Aria CFF in the Cayman Islands and Aria DMCC in Dubai—are said to be controlled by Matthew Brittain and his wife, Cecilia. Despite being legally separate, their operations were allegedly blurred, and funds earmarked for one were shifted to the other.

By mid-2023, with redemptions failing and liquidity drying up, Techteryx was forced to take full control of TUSD’s operations. It was at this point, court documents claim, that Justin Sun extended a lifeline by injecting emergency liquidity in the form of a loan, allowing retail redemptions to continue. The company also quarantined 400 million TUSD tokens to avoid further risk to holders.

First Digital has denied any wrongdoing, stating that all actions were taken under Techteryx’s direction. Meanwhile, Matthew Brittain has dismissed the accusations as baseless and claimed Techteryx was fully aware of the investment terms.

The revelations come amid a series of compounding crises for TUSD, including the collapse of Prime Trust—its fiat on-ramp partner—and an SEC settlement involving prior owners TrueCoin and TrustToken, who paid $500,000 over misleading statements about reserve practices.

In a telling admission, Aria’s Brittain noted that his fund “was never meant to be highly liquid or suitable for a stablecoin’s reserves,” raising questions about the oversight—or lack thereof—that allowed such a misstep in the first place.
