Can you verify Usual USD0 (USD0) reserves yourself?
You can read part of USD0's backing on-chain yourself; the rest rests on an off-chain layer you take on an attestation.
Backed by tokenized T-bill and money-market reserves held in Usual contracts and readable on Etherscan, with a Chainlink Proof of Reserve and Price Feed overlay. Each RWA token's par value still rests on the underlying tokenized fund's own off-chain audit and administration.
What you cannot verify yourself: The par value of each tokenized RWA, which rests on its off-chain fund-administrator attestation. Redemption terms are governance-controlled (the January 2025 USD0++ repricing is the precedent).
Issued by Usual. "Partly attestor-required" describes the structure of the verification, not the quality of the issuer.

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.
