Tether Accepts Big 4 Audit For USDT Stablecoin Reserves

Tether reveals plans for an audit from a Big 4 firm.

Tether has announced that it will soon be holding an official audit from a top global accounting firm to go through its underlying stablecoin reserves. USDT stablecoin supply currently stands at 184.1B with 38B of daily transfers and 564M users worldwide. For now, the exact auditor is still being kept under wraps.

CEO Paolo Ardoino expressed:

“Tether’s mission has always been to build trust through action, not promises. Trust is built when institutions are willing to open themselves fully to scrutiny. This audit represents years of work to strengthen our systems so that Tether can meet the highest standards applied in global finance.

So far, Tether has been using BDO Advisory Services to verify its assets and liabilities from disclosed attestation reports (last one published 31 December 2025). These were based on some principles of the IFRS (International Financial Reporting Standards Foundation) under IASB (International Accounting Standards Board).

In the U.S., there is the latest stablecoin specific accounting criteria developed by the AICPA (American Institute of CPAs), which is already used by the likes of PwC (PriceWaterhouseCoopers), Deloitte (chosen by Paxos and Ripple), EY and KPMG.

Tether’s USAT stablecoin has already undergone its first audit by Deloitte using the aforementioned AICPA standard, and is being actively managed by partner issuer Anchorage Digital to comply with the Genius Act.
