Fraud Allegations, Insolvency Claims, and a Market Rattled by Broken Trust
TrueUSD (TUSD), once marketed as a fully-backed stablecoin, is now at the center of a mounting crisis that has unraveled its internal operations and exposed deep structural flaws across its custodial and investment channels. Between March and April 2025, more than $456 million in TUSD reserves were discovered to be tied up in unauthorized and illiquid investments. The revelation has raised serious questions about fiduciary trust, reserve integrity, and the broader implications for stablecoin markets.
Techteryx, the company that acquired TUSD in late 2020, traced the shortfall to First Digital Trust (FDT), the fiduciary tasked with safeguarding the reserves. Rather than holding the funds in liquid assets as intended, FDT redirected the capital into Aria Commodities DMCC, a Dubai-based trade infrastructure firm. These funds were originally earmarked for the Aria Commodity Finance Fund (Aria CFF), a Cayman Islands vehicle. The move effectively severed the liquidity lifeline TUSD relied on to support redemptions, locking funds in manufacturing plants, mining sites, and port infrastructure.
The tangled investment trail points to Matthew Brittain as the orchestrator behind Aria CFF through his entity Aria Capital Management Ltd., while Cecilia Brittain is named as the sole shareholder of Aria Commodities DMCC. Despite their separate legal status, court documents describe the entities as “deeply intertwined.” Techteryx has filed legal action, accusing the parties involved of financial mismanagement, embezzlement, fraud, and misrepresentation. Allegations include unauthorized loans issued under the guise of trade finance deals that were misrepresented on FDT’s balance sheets.
As TUSD’s liquidity deteriorated further by mid-2023, Tron founder Justin Sun stepped in with emergency capital to prevent a full-scale collapse. Sun’s intervention helped Techteryx quarantine $400 million of compromised reserves, giving users temporary redemption confidence and halting a potential bank run. According to Sun, his decision was driven by a need to preserve trust in stablecoins, stating, “I stepped in to help stabilize TUSD because I believe in the importance of maintaining trust in stablecoins and ensuring the security of their reserves.”
The situation escalated further on April 2, when Justin Sun took to X to publicly accuse First Digital Trust of being “effectively insolvent.” He urged users to withdraw their assets and called on Hong Kong regulators to step in, warning that the city’s credibility as a global financial hub was at stake.

The timing of his warning had immediate market consequences. FDUSD, a separate stablecoin issued by FDT, fell to $0.8726, erasing roughly $130 million in market capitalization before partially recovering to $0.98.

The sell-off underscored FDUSD’s exposure on Binance, where 94% of its $2.2 billion supply is held—$1.5 billion in user deposits and another $700 million in corporate funds. The volatility was further amplified by FDUSD/BTC, one of Binance’s most traded pairs.

FDT quickly moved to deny Sun’s insolvency claims. A spokesperson asserted that FDUSD remains fully backed 1:1 by U.S. Treasury Bills, with all reserve ISIN numbers published in their attestation reports. The firm called Sun’s public accusations a “coordinated smear campaign” aimed at damaging a competitor’s reputation and confirmed plans to pursue legal action. To address public concerns, FDT hosted a live AMA session on April 3 at 4 PM (Hong Kong time), attempting to reassure users of the stablecoin’s solvency and operational transparency.

This isn’t the first time TUSD has faced serious setbacks. In previous years, its custodian partner Prime Trust fell into receivership under allegations of embezzlement. Meanwhile, the SEC had reached a cease-and-desist settlement with former TUSD operators—TrueCoin and TrustToken—over false claims regarding full dollar backing and investments in unregulated offshore funds.
