Tether announced on Tuesday that it has engaged a Big Four accounting firm to conduct what the firm says is its “first full independent financial statement audit.” The issuer of USDT, the largest stablecoin by market cap with over $184 billion, did not name which specific firm would conduct the audit, and described it as potentially the largest inaugural audit in financial markets history.
The company, which reports a global user base of more than 550 million, said the engagement follows a competitive onboarding process during which multiple audit firms assessed Tether's systems, internal controls, and financial reporting.
The move comes after years of criticism over Tether's transparency practices. Rather than full audits, Tether has historically provided quarterly attestations from BDO Italia — a more limited form of financial review. In 2021, the Commodity Futures Trading Commission (CFTC) issued a $41 million fine over misleading claims that USDT was fully backed by U.S. dollars.
