Structure and safeguards

As reported by Bridge

Issuance and custody

  • Open USD is governed and operated by Open Standard; reserve figures here are reported by Bridge.
  • Reserve coverage is calculated from the amounts in Bridge's OUSD transparency report.
  • This dashboard is informational and is not an independent attestation of reserves.
  • See Open Standard for OUSD governance and product information.

Reading this report

  • Cash and non-cash reserves are shown separately.
  • Non-cash reserves combine the other asset types in Bridge's report.
  • The public report does not include orchestration inventory or a configured liquidity target.
  • Figures remain unavailable when a source cannot be refreshed.

Method and APIs

Read-only requests

The page refreshes through a same-origin Vercel Function using Bridge's public OUSD transparency report, which requires no API key. Reserve responses are cached at the edge for five minutes and may be served stale for up to one hour while revalidating. The displayed reserve timestamp comes from Bridge. Tempo supply is read separately from the OUSD contract through Tempo's public JSON-RPC endpoint.
