USDC reserve coverage on ReserveBeat is read from Circle's own published attestation report as of 2026-08-31, 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.

03Reconciliation

Reconciliation — measured vs attested

This token circulates on multiple networks; the independently measured figure covers the Ethereum slice only. Comparing it against the attested total is a bound check, not a full reconciliation.

04Corroboration

Regulator-filed corroboration

Regulator-filed corroboration shows the SEC-filed N-MFP net-asset figure for a fund the issuer's own attestation names, side by side with the attested figure, each carrying its own provenance. It never enters any ratio, never adjusts any attested figure, and says nothing about reserves the filing does not cover; a divergence beyond tolerance opens an incident and both figures keep rendering unchanged.

USDC attested reserve coverage on ReserveBeat — a figure read verbatim from the issuer's published report, never a solvency claim
[![USDC attested reserve coverage on ReserveBeat — a figure read verbatim from the issuer's published report, never a solvency claim](https://reservebeat.com/badge/usdc.svg)](https://reservebeat.com/stablecoins/usdc?utm_source=badge&utm_medium=bio&utm_campaign=usdc-coverage)

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.

Other badges for this token, and the evidence-chain badge, are in the badge builder.

Paste this into any page to show this token's live figure card, served from ReserveBeat. It shows the same states as the badge above — a ratio only where the issuer's report states one per token, and a stated absence otherwise — and links back to this page. 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.

Timestamps reflect the underlying data — when a figure was captured or a report was published — never when a page was built.

08Questions

Common 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.
