Tether Holdings has enlisted Deloitte to audit its USAT stablecoin reserve report, marking the first time the firm has received attestation from a Big Four accounting firm. The audit, conducted by Deloitte, reviewed the reserve report submitted by Anchorage Digital Bank, confirming that $17.6 million in reserve assets back the 17.5 million USAT tokens in circulation. This move signifies Tether's re-entry into the U.S. market, following regulatory challenges and a $41 million fine in 2021 for misrepresenting reserve assets.
