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. Do not trust the issuer, and do not trust us. This page reads FDUSD's live supply straight from the chain and shows you, honestly, where verification ends and trust begins.
Issued by First Digital. It is not an audit, a rating, or a solvency opinion, and FDUSD appearing here is not an endorsement. "Attestor-required" describes the structure of the verification, not the quality of the issuer.
The part you can always verify: live supply
Total supply is a contract function anyone can call. Below is FDUSD read live from the chain, with the exact command to reproduce it. This is the one number you never have to take on faith.

Always confirm you are reading the canonical contract address. A look-alike token can copy any name or symbol; only the address is identity.
The harder question: can you verify FDUSD's reserves?
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.
On-chain FDUSD supply on Ethereum mainnet, redeemable through First Digital.
That the cash and cash-equivalent reserves First Digital's custodian holds in Hong Kong exist at the value in the monthly attestation.
The reserve backing sits off-chain, so you read a third-party attestation of it rather than the accounts themselves. To move FDUSD toward attestor-optional, an issuer would have to publish raw on-chain reserves plus a proof re-derivable from public inputs. That is a property of the architecture, not of effort, so it is a rebuild, not a new auditor.
