Reserve evidence, published risk rating, and scope controls are separate signals.
Published asset rating; separate from the reserve snapshot
Observed reserves divided by liabilities across a common scope
Observed reserves less circulating liabilities
Liability operand published by the issuer in the cited disclosure

Evidence classification
Mutually exclusive assurance layers. Each side sums to 100% and is assessed separately.
Reserve evidence
strongest layer per dollar- Evidence coverage
- 100%
- On-chain
- 0%
- Off-chain
- 100%
Current evidence covers 100% of observed reserve value: 0% on-chain and 100% off-chain. 100% comes from the cited issuer or source report and is not independently reproduced for the current snapshot. Coverage describes evidence availability, not an audit or solvency opinion.
Liability evidence
classified separately- Evidence coverage
- 100%
- On-chain
- 0%
- Off-chain
- 100%
The liability operand comes from the same cited issuer disclosure as the reserve figure; it is not an independent on-chain supply read.
Reserves vs liabilities
Observed backing against circulating supply. Ratio appears only on scope-compatible points.

Circle weekly disclosure; reserves and USDC in circulation are rounded to $0.01bn and share the same stated as-of date. Monthly third-party assurance is a separate evidence layer.

Market context
Investable TVL and net APR for USDC. This series is not reserve evidence and does not enter the collateral ratio.
Derived points reconstruct historical vault snapshots using today's vault eligibility; observed points are captured directly from that day's investable set.
Published coverage basis
Observed figures from Philidor’s stablecoin backing look-through. Reserve value is partitioned by its strongest admissible current evidence layer: direct on-chain verification, issuer-published third-party attestation results, source report only, or unverified. Philidor does not independently fetch the auditor artifacts behind issuer-published attestation results. Liability evidence is measured separately. Shares are mutually exclusive and total 100%; 0% direct on-chain does not mean 0% backing. Reserve and liability timestamps are separate, stale evidence fails closed, and cross-time or cross-scope ratios are withheld. Unobserved fields are null with a reason; nothing is inferred. This is decision evidence, not a solvency guarantee.
