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. Do not trust the issuer, and do not trust us. This page reads sDAI's live supply straight from the chain and shows you, honestly, where verification ends and trust begins.
Issued by Sky (formerly MakerDAO). It is not an audit, a rating, or a solvency opinion, and sDAI appearing here is not an endorsement. "Attestor-optional" 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 sDAI read live from the chain, with the exact command to reproduce it. This is the one number you never have to take on faith.
Reproduce the supply read yourself

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 sDAI's reserves?
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).
On-chain supply and the on-chain exchange rate to DAI.
The off-chain real-world-asset portion of the underlying DAI backing.
The reserve backing is readable on-chain, so a third-party attestor is optional on that leg. sDAI is on the strong end of this axis for its reserve leg. That is not the same as risk-free; the standing risks are smart-contract and collateral risk, not attestor trust.

Common questions about sDAI
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. On-chain supply and the on-chain exchange rate to DAI. The off-chain real-world-asset portion of the underlying DAI backing. On-chain supply is something you can always read yourself; the reserves are where the trust boundary sits, and this page shows exactly where.
Who attests sDAI's reserves?
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). The reserve figure runs through Underlying DAI RWA allocation rests on partner attestations, which is a legitimate, common model. You read that attestation rather than the underlying accounts. This is a structural fact about the verification, not a judgment on the issuer.
Which sDAI contract is canonical, and how do I confirm I have the right one?
sDAI is a crypto-collateralized token issued by Sky (formerly MakerDAO) at 0x83f20f44975d03b1b09e64809b757c47f942beea on Ethereum. A look-alike token can copy any name or symbol, so only the address is identity: confirm you are reading the canonical contract above before trusting any supply or reserve figure.
Run this on sDAI yourself, or get a signed record of it.
The check above is free and live. Paste sDAI's address into the free tool to read it interactively, 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.
The $29 read is signed instantly 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.
