Reserves as stated.
Supply as measured.
Stablecoin reserve data you can build on: every attested figure served verbatim from the issuer’s own report, traced to a hash-anchored capture of that report.

01Board
Every tracked stablecoin, at its stated scope.
Every figure on this board traces to a primary source — a hash-anchored capture of the issuer’s published attestation report, or a public Ethereum contract read at a quorum of independent RPC providers — and renders verbatim at its stated scope.
Data as of . The newest on-chain supply reading on this board. Each row's report date and status are its own.
- Stated reserves
- $187,751,426,411
- Stated liabilities
- $183,622,105,630
- Attested coverage divides two numbers the issuer’s own report states at the same as-of date.
- Stale: the latest report is more than a month old.
- Overdue: past the expected report date plus a 14-day grace (none today).
- Share of stated total: each issuer’s stated total reserve assets against $275,851,822,942, drawn to scale (1px minimum).USDT at its group scope.Supply to two decimals, truncated.
02Method
Three steps from report to board.
- 1
Primary-source capture
Each issuer’s published attestation report is captured as published and hash-anchored. Every figure cites that capture.
- 2
Verbatim parsing
Figures are extracted exactly as stated. Parsers refuse on unexpected layouts rather than guess. Nothing is rounded or recomputed.
- 3
Independent on-chain measurement
Ethereum supply is read at a quorum of independent RPC providers, storage-proven where possible.
03API
A free read API. Verbatim JSON.
Every board figure as JSON, with its source tier, as-of date and block number. No key required.

06Questions
Common questions
What is ReserveBeat?
Independent monitoring of public stablecoin reserve figures. For each tracked token it captures the issuer’s published attestation report, parses the figures verbatim, and sets them beside on-chain supply measured on Ethereum, with every figure’s source tier and as-of date. It is not an auditor and does not score issuers.
Is a coverage figure a solvency judgment?
No. A coverage figure divides two numbers the issuer’s own report states at the same as-of date. ReserveBeat states no opinion on any issuer’s solvency.
Where do the figures come from?
From two kinds of primary source: the issuer’s published attestation report, captured and hash-anchored, and public Ethereum contract reads taken at a quorum of independent RPC providers, storage-proven where possible.
Are the tracked issuers involved with ReserveBeat?
No. No tracked issuer is affiliated with ReserveBeat or endorses it.
