USDC reserve coverage
USDC reserve coverage on ReserveBeat is read from Circle's own published attestation report as of 2026-05-29, cross-checked against independently measured on-chain supply. Every figure renders verbatim at its stated scope, with its source tier and freshness beside it — never adjusted, and never a solvency judgment.

Embed this badge
[](https://reservebeat.com/coverage/usdc)This badge serves the live figure this page renders — read verbatim from the issuer's published attestation report at its stated scope, and linked back to this page's methodology and limits. When figures are withheld or attested only at consolidated scope, the badge says so instead of showing a ratio. It is not a solvency claim.
Each coverage ratio divides two figures from the same issuer attestation at the same as-of date. On-chain measurements never enter a ratio — they are the independent cross-check of the liability side.
Last updated: Timestamps reflect the underlying data — when a figure was captured or a report was published — never when a page was built.
Frequently asked questions
What does the coverage ratio mean?
It divides two figures the issuer's own attestation report states at the same as-of date — total reserve against tokens outstanding. It renders verbatim with its source tier and freshness, and it is never a judgment of reserve sufficiency.
Why might no ratio be shown for this token?
Either the issuer attests only at consolidated group scope — one report covering several tokens, which the page renders as stated rather than inventing a per-token ratio — or no attestation series is held yet. Absence renders plainly, never as an estimate.
How is on-chain supply measured?
Directly from the token's public Ethereum contract at a quorum of independent RPC providers. Every measurement carries the block number and timestamp it was taken at, so freshness is visible beside the figure.
What does the disclosure score measure?
It counts which independently checkable dimensions an issuer's disclosure states — as-of dates, scope, itemization — against a fixed public rubric. It measures disclosure completeness only; it says nothing about reserve quality or sufficiency.
