Transparency by default.
Every dollar of USDC and euro of EURC is fully backed. Every reserve is attested by a top-4 accounting firm. Every flow is verifiable onchain.
Trust, but verify.
Transparency isn't a feature at Circle — it's a foundation. Every USDC and EURC is fully backed by reserves held in cash and short-duration US Treasuries, and those reserves are verified every month by Deloitte, a top-4 accounting firm.
Beyond attestations, USDC issuance and redemption happen onchain, where anyone can independently verify supply in real time across every supported network.
