On July 20, the stablecoin project USDC released its May 2021 asset verification report, marking the first time it disclosed a granular breakdown of reserves backing USDC—similar to Tether’s transparency efforts.
As a U.S.-registered and regulated entity, USDC publishes monthly reserve attestations, contrasting sharply with Tether’s opaque operations. But how do their reserve structures differ?
Asset Verification vs. Audit: Critical Distinctions
Both USDC and Tether provide "attestations" (not audits) from accounting firms. Attestations are less rigorous—they verify asset existence without scrutinizing fund origins.
For example, a 2021 New York Attorney General report revealed Tether temporarily borrowed $382M from Bitfinex in 2017 to pass an attestation, highlighting reserve inadequacies.
👉 Why audits matter for stablecoins
Key Differences in Attestation Providers
- USDC: Verified by Grant Thornton LLP (global top 6 accounting firm).
- Tether: Verified by Moore Cayman (unranked in top 10).
This choice reflects USDC’s commitment to higher credibility standards.
Reserve Composition: USDC vs. USDT
| Asset Class | USDC Reserves | USDT Reserves |
|---|---|---|
| Cash & Cash Equivalents | 61% | 75.85% |
| Commercial Paper | 9% | 65.39%* |
*Of Tether’s cash equivalents, 65.39% is commercial paper.
USDC’s Nuanced Approach:
- Classifies cash equivalents as assets maturing <90 days.
- Segregates longer-term instruments like bank deposits (≤13 months) and Treasuries (≤3 years).
Notably, USDC hasn’t disclosed its commercial paper maturity distribution—a gap Tether addresses.
The Push for Greater Transparency
Circle CEO Jeremy Allaire tweeted on July 8:
"Circle intends to become the most transparent operator of full-reserve stablecoins... upcoming filings will detail USDC reserves."
With Circle’s planned Q4 2021 IPO via SPAC, mandatory financial disclosures will likely expose more reserve data.

Why Transparency Matters
- Regulatory Spotlight: U.S. Treasury Secretary Yellen convened agencies on July 19 to discuss stablecoin oversight.
- Market Confidence: Detailed attestations mitigate risks like fractional reserves.
FAQ
Q: Is USDC safer than USDT?

Q: What’s the biggest risk in stablecoin reserves?
A: Over-reliance on short-term commercial paper, which may face liquidity crunches.
