TUSD vs USDT Overview

TrueUSD (TUSD) and Tether (USDT) are both fiat-backed stablecoins pegged to the US dollar, but they occupy vastly different positions in the market. USDT dominates with roughly 59% of the global stablecoin market cap at approximately $183 billion. TUSD, once a top-five stablecoin at $3.4 billion in mid-2023, has collapsed to around $494 million following a series of reserve scandals, SEC enforcement actions, and ownership controversies.

TUSD was originally marketed as the more transparent alternative to USDT, pioneering real-time reserve attestation through Chainlink Proof of Reserve. That narrative fell apart when investigations revealed that the reserves backing TUSD were invested in illiquid speculative assets rather than liquid dollar equivalents. This comparison examines where both stablecoins stand today across transparency, reserves, regulation, and practical utility.

Reserve Transparency and Attestation

TUSD's defining claim was real-time reserve verification. In 2023, TrueUSD became the first USD-backed stablecoin to integrate Chainlink Proof of Reserve, which prevents the smart contract from minting new tokens unless the oracle confirms that corresponding USD deposits exist. The feed updates daily via LedgerLens Oracle Services.

The limitation of this system became painfully clear: the Chainlink oracle verified bank account balances, not the quality or liquidity of the underlying assets. While the on-chain feed showed adequate reserves, approximately $456 million had been redirected by First Digital Trust (TUSD's Hong Kong fiduciary) to Aria Commodities DMCC, an unauthorized Dubai entity that invested the funds in illiquid projects including mining operations, maritime vessels, and renewable energy ventures.

USDT took a different approach. For years, Tether published quarterly attestation reports prepared by BDO Italia, covering reserve composition and confirming that assets exceeded liabilities. Critics argued these were not full audits. That changed in August 2026, when Tether announced that KPMG U.S. completed a full financial audit of Tether International's statements for the year ending December 31, 2025. KPMG issued an unqualified opinion, confirming reserves exceeded liabilities by $6.8 billion. For a broader analysis of stablecoin attestation practices, see our reserve transparency audit research.

Reserve Composition

Tether's reserves are dominated by US Treasury bills, with smaller allocations to secured loans, gold, and Bitcoin. The Q3 2025 attestation confirmed year-to-date net profit surpassing $10 billion, generated primarily from T-bill yields. Tether previously held significant commercial paper positions, but eliminated that exposure in response to market criticism and shifted toward the highest-quality liquid assets.

TUSD's reserve composition has been far more opaque. The SEC alleged that by September 2024, 99% of TUSD reserves were held in a speculative offshore fund rather than in liquid dollar equivalents. Following the crisis, Techteryx announced it raised its reserve ratio to 100% within the United States and moved to direct banking relationships in Hong Kong and Singapore, eliminating the intermediary structures that enabled the misappropriation. However, TUSD has not published detailed reserve breakdowns comparable to Tether's quarterly disclosures.

Ownership and Governance

TUSD was originally created by TrueCoin LLC (a subsidiary of Archblock Inc., formerly TrustToken). In December 2020, TrueCoin transferred business ownership to Techteryx, an Asia-based consortium whose ultimate beneficial owner is listed as Li Jinmei in Hong Kong court filings. Despite the transfer, Archblock continued managing operations, compliance, and reserve oversight until July 2023, when Techteryx assumed full operational control of all offshore operations.

Justin Sun, the founder of Tron, has described himself as an advisor to Techteryx. His involvement proved more substantial: when TUSD's reserves became illiquid in 2024, Sun provided an emergency loan of approximately $456 million to backstop the stablecoin reserve and maintain redemptions. Techteryx quarantined 400 million TUSD so retail redemptions could continue. The opacity around Sun's relationship with Techteryx has been cited by regulators and rating agencies as a governance concern.

Tether Holdings is incorporated in the British Virgin Islands. The company is controlled by Jean-Louis van der Velde (CEO), Paolo Ardoino (CTO, who has taken an increasingly public leadership role), and Giancarlo Devasini (CFO). Tether's corporate structure and beneficial ownership have faced scrutiny, but the company has never undergone an ownership transition comparable to TUSD's.

Depegging History

TUSD experienced multiple depeg events between 2023 and 2024 that progressively eroded market confidence.

  • May 2023: TUSD traded as high as $1.20 on Binance during SUI farming pool activity
  • June 2023: depegged after TUSD's US custodian Prime Trust was placed into receivership by Nevada regulators, owing $85 million with approximately $3 million available
  • August 2023: dropped to $0.80 on Binance.US and $0.9974 vs USDT on Binance in multiple incidents within a single month
  • November 2023: fell to $0.988
  • January 2024: dropped to $0.984 amid difficulties posting real-time attestations
  • September 2024: further instability following the SEC fraud charges announcement

USDT has experienced smaller and shorter depegs. The most notable was a brief dip to approximately $0.95 during the broader crypto market panic of May 2022, though it recovered within hours. USDT's deep liquidity across dozens of exchanges and trading pairs generally allows arbitrageurs to restore the peg quickly.

For context on how other stablecoins have handled peg stress, see our stablecoin depegging history tracker and our stablecoin comparison tool.

Both stablecoins carry regulatory baggage, though of different kinds.

In September 2024, the SEC charged TrueCoin LLC and TrustToken Inc. with fraudulent and unregistered sales of investment contracts involving TUSD from November 2020 through April 2023. The SEC alleged both companies falsely marketed TUSD as "fully backed by U.S. dollars" while substantial reserves were invested in speculative offshore funds. By March 2022, over $500 million in backing assets were in risky offshore investments. The case settled with civil penalties of $163,766 each and disgorgement of $340,930 from TrueCoin, without admission of wrongdoing.

In November 2025, S&P Global Ratings assigned TUSD its lowest stability score of 5 out of 5 ("weak"), citing governance concerns and scarce reserve information. TUSD is not MiCA-compliant, leading to delistings across European exchanges: Binance removed TUSD spot trading pairs for EEA users by March 2025, and Kraken completed removal by August 2025.

Tether paid an $18.5 million settlement to the New York Attorney General in 2021 over claims that the company misrepresented the extent to which USDT was backed by fiat reserves. Despite this, USDT has not faced direct SEC enforcement action. USDT is also not MiCA-compliant and has faced delistings in the EU, though its dominance outside Europe remains unaffected. The completion of the KPMG audit in 2026 has partially addressed long-standing transparency criticisms.

Chain Support and Liquidity

USDT is natively deployed on 15+ blockchains including Ethereum, Tron, Solana, Avalanche, Polygon, Arbitrum, Optimism, BNB Smart Chain, TON, and others. Tether discontinued direct issuance on five legacy blockchains (Omni Layer, Bitcoin Cash SLP, Kusama, EOS, Algorand) as of September 2025, though wallet-to-wallet transfers on those networks remain possible.

TUSD is natively deployed on Ethereum, Tron, BNB Smart Chain, and Avalanche, with bridged versions available on Polygon, Arbitrum, Optimism, and several smaller chains. However, TUSD's liquidity on most chains has thinned considerably alongside its market cap decline. Trading pairs have been removed from major exchanges, and market depth on remaining pairs is a fraction of what it was at peak.

For users seeking stablecoins on the Bitcoin network specifically, neither TUSD nor USDT operates natively on Bitcoin. USDB, issued by Flashnet, is designed for Bitcoin-native payments via Spark, enabling instant, near-zero-fee dollar transfers without bridging.

Market Share Trajectory

TUSD's rise and fall illustrates the fragility of trust in stablecoin markets. In early 2023, Binance adopted TUSD as a primary trading pair after discontinuing BUSD, driving TUSD's circulating supply past $3.4 billion by June 2023. At its peak, TUSD held roughly 1.8% of the total stablecoin market cap.

The decline was rapid. The Prime Trust receivership, repeated depegs, SEC charges, and the $456 million reserve misappropriation scandal drove holders to exit. By September 2026, TUSD's market cap had fallen approximately 85% from peak to around $494 million. In July 2025, Ripple's RLUSD surpassed TUSD at $517 million, pushing TUSD further down the rankings.

USDT, by contrast, has grown steadily. Its market cap expanded from roughly $83 billion at the start of 2024 to over $183 billion by September 2026. USDT processed over $156 billion in small payments (under $1,000) throughout 2025 alone, reflecting growing adoption for everyday transactions in emerging markets.

When to Use TUSD vs USDT

Given TUSD's current state, the practical use cases where it outperforms USDT are limited. USDT offers superior liquidity, broader chain availability, deeper exchange support, and (following the KPMG audit) a stronger transparency track record than TUSD.

TUSD may still appear in legacy portfolios, existing DeFi positions, or arbitrage opportunities during temporary depegs. However, new users and institutions should evaluate TUSD's S&P "weak" stability rating, its SEC settlement history, and its diminished liquidity before taking any position.

Frequently Asked Questions

Is TUSD safer than USDT?

No. Despite TUSD's original marketing around real-time reserve attestation, the SEC's 2024 enforcement action revealed that up to 99% of TUSD reserves were invested in speculative offshore assets. S&P Global assigned TUSD its lowest stability score (5/5, "weak") in November 2025. USDT, while historically criticized for opacity, completed a full KPMG audit in August 2026 with an unqualified opinion and maintains a reserve buffer exceeding $4 billion.

What happened to TrueUSD reserves?

First Digital Trust, the Hong Kong-based fiduciary managing TUSD reserves, allegedly redirected approximately $456 million to Aria Commodities DMCC, an unauthorized Dubai entity. The funds were invested in illiquid ventures including mining, maritime vessels, and renewable energy. Justin Sun provided an emergency loan to backstop TUSD and maintain retail redemptions. Techteryx has since restructured its reserve management with direct banking relationships.

The Chainlink Proof of Reserve feed for TUSD remains active on Ethereum. However, the 2023-2024 reserve crisis demonstrated a fundamental limitation: the oracle verifies bank account balances but cannot assess the quality or liquidity of the underlying assets. A bank account can show adequate balances while the actual reserves are locked in illiquid investments, which is precisely what occurred with TUSD.

Why did TUSD depeg multiple times?

TUSD experienced at least six depeg events between May 2023 and September 2024. The causes included the Prime Trust receivership (June 2023), which disrupted USD minting; the discovery that reserves were invested in speculative assets rather than liquid dollars; exchange delistings that removed trading pair liquidity; and the SEC fraud charges announcement (September 2024). Each event triggered further holder exits, creating a negative feedback loop of declining market cap and thinning liquidity.

Who owns TrueUSD?

TrueUSD is owned by Techteryx, an Asia-based consortium that acquired the stablecoin from TrueCoin LLC in December 2020. Hong Kong court filings list Li Jinmei as the ultimate beneficial owner. Justin Sun, founder of Tron, describes himself as an advisor to Techteryx, though his provision of a $456 million emergency loan and active involvement in litigation against First Digital Trust suggest a deeper role. The opacity around Techteryx's governance structure has been cited as a risk factor by S&P Global.

Has Tether ever been fully audited?

Yes. In August 2026, KPMG U.S. completed the first full financial audit of Tether International's financial statements for the year ending December 31, 2025. KPMG issued an unqualified (clean) opinion, confirming reserves exceeded liabilities by $6.8 billion. Prior to this, Tether relied on quarterly attestation reports from BDO Italia, which are less comprehensive than a full audit but provided regular snapshots of reserve composition.

Is TUSD available on European exchanges?

No. TUSD is not MiCA-compliant, and major European exchanges have removed it. Binance delisted TUSD spot trading pairs for EEA users by March 2025, and Kraken completed removal by August 2025. Neither TUSD nor USDT currently meets MiCA requirements for the European market.
