Waiting for the contract supply observation.
This dashboard is informational, not an independent reserve attestation. Reserve responses cache for five minutes and may be served stale for up to an hour while revalidating. Daily history caches hourly.
Open USD is governed and operated by Open Standard. Bridge reports the all-chain reserve figures; Tempo contract supply is fetched independently. Non-cash reserves group the other asset types in Bridge's report. The public report does not include inventory or liquidity targets.
History uses daily supply and peer-to-peer volume from Snowflake. Transfers exclude mint, burn and fee events. The latest Tempo supply observation is appended to the supply chart.
GET https://transparency.bridge.xyz/v0/stablecoins/ousd requires no API key. Tempo observations use eth_blockNumber and eth_call totalSupply() at https://rpc.tempo.xyz.
