Key Highlights
- Tether said it has formally engaged a Big Four accounting firm for its first full independent financial statement audit.
- The move would take the company beyond reserve attestations toward broader financial statement review.
- The company said the process follows an onboarding review of its controls, reporting systems, and reserve structure.
Tether, the issuer of USDT, said it has formally engaged a Big Four accounting firm to carry out its first full independent financial statement audit. The step would move the stablecoin issuer beyond the reserve attestations that have long defined disclosure standards in the sector.
According to the official announcement, the engagement is intended to provide a fuller review of its financial statements, reserves, internal controls, and reporting systems as scrutiny around stablecoin backing and transparency continues to intensify.
Shift from attestations to a full audit
Tether framed the move as a step up from the attestation model commonly used by stablecoin issuers. While attestations typically provide a snapshot of reserve positions at a given time, a full audit is broader in scope and is meant to test financial reporting more comprehensively.
According to the company, the onboarding phase with the accounting firm concluded a few weeks ago and included a review of Tether’s systems, internal controls, and financial reporting processes.
Pressure on reserve transparency remains central
The audit push comes as reserve quality and disclosure remain central issues for stablecoin issuers, particularly for Tether, whose USDT is the largest stablecoin by market capitalization.
Tether said USDT’s market capitalization has surpassed $184 billion. The company also said it has been adjusting reserve holdings and will move listed securities in the coming days as part of this process. It added that the audit is expected to provide fuller visibility into the composition and positioning of reserves.
Internal preparation
Tether said it has spent the past several years strengthening governance, financial controls, and internal systems in preparation for a full audit. The company also pointed to the appointment of CFO Simon McWilliams in early 2025 as part of this effort.
In its statement, Tether said the auditor was selected through a competitive process and that multiple firms were involved during the review stage because of the scale and complexity of the assignment.
Tether’s broader push
Separate from the audit announcement, Tether recently announced an investment in Ark Labs, the developer behind the Bitcoin infrastructure project Arkade, as part of a $5.2 million funding round. According to the company, part of the investment will go toward expanding the infrastructure needed to move and settle stablecoins more efficiently on Bitcoin.
The disclosure adds another layer to Tether’s current strategy: while the company is seeking greater scrutiny of its balance sheet through a full audit, it is also continuing to fund infrastructure tied to stablecoin use and settlement on Bitcoin.
Why the move matters
A completed Big Four audit would be one of the clearest attempts yet by a major stablecoin issuer to answer longstanding questions about transparency and reserve backing through a more conventional financial reporting process.
For now, Tether has announced the engagement, not the completion of the audit. This leaves the next stage centered on whether the process results in a published full financial statement audit and what new details it provides about the company’s reserves and liabilities.
