Independent monitoring of public stablecoin figures. The methodology and its limits render on every page — nothing here is a solvency claim about any issuer.
Tracked tokens are subjects of public data: supply figures are read from their public Ethereum contracts, and composition figures from the issuers' own published attestation reports. No tracked issuer is a customer and none has endorsed this board.

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.

NOT MEASURED — no on-chain snapshot exists within the pairing window of this as-of date. The cell renders its absence rather than a stretched match.
Attested coverage series
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.

Regulator-filed corroboration NOT_APPLICABLE
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.
no SEC-registered fund is named in this token's attested reserves
