Can you verify Savings Dai (sDAI) reserves yourself?
sDAI's backing is crypto collateral held on-chain, readable directly on a block explorer, with no attestor in the reserve path.
ERC-4626 savings wrapper around DAI. The on-chain exchange rate to DAI is readable directly; the underlying DAI carries DAI's own backing profile (on-chain collateral plus an off-chain RWA allocation).
What you cannot verify yourself: The off-chain real-world-asset portion of the underlying DAI backing.
Issued by Sky (formerly MakerDAO). "Attestor-optional" describes the structure of the verification, not the quality of the issuer.
Run this on sDAI 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.
Live supply, and the command that reproduces it
