Can you verify First Digital USD (FDUSD) reserves yourself?
FDUSD's reserves sit off-chain, so you read a third-party attestation of them rather than the accounts themselves.
Backed by cash and cash-equivalent reserves held by a custodian in Hong Kong, disclosed through monthly third-party attestation reports. Reserves are off-chain.
What you cannot verify yourself: That the cash and cash-equivalent reserves First Digital's custodian holds in Hong Kong exist at the value in the monthly attestation.
Issued by First Digital. "Attestor-required" describes the structure of the verification, not the quality of the issuer.
Run this on FDUSD yourself, or get a signed record of it.
The read below is free and live. Or get a machine-signed, point-in-time read of this exact address in about two minutes, that anyone you forward it to can verify in three lines without trusting you.
Signed on the page after you pay in USDC on Base: no email, no wait. It signs public on-chain bytes only (supply, decimals, and symbol at a block), not a solvency opinion and not a claim about who controls the address. Issuing a dollar of your own? The GENIUS-readiness kit is $999 setup then $99 a month. Not compliance and not an audit.
