Most stablecoin issuers, including Circle, Paxos, Huobi and Gemini, release attestation reports every month. For TrueUSD, the attestation is released 24/7 – you can get a report whenever you want, showing the state of its U.S. dollar collateral up to the minute. On the other end of the spectrum, Tether said it would issue attestation reports on a quarterly basis.
