The short answer
USDY scores higher on safety (88 vs 85), driven mainly by collateral quality and disclosure. USDY has deeper tracked liquidity ($2.17B), which is what determines whether you can exit at size. DAI currently earns up to 4.71% — remember that any rate above the T-bill yield is payment for a risk.
If both are fiat-reserve tokens, note that holding both is not diversification: they share the same short-dated Treasury and banking exposure. Genuine diversification means mixing collateral structures.

DAI vs USDY: frequently asked questions
Is DAI or USDY safer?
+
On our composite safety score USDY rates 88/100 versus 85/100 for DAI. The score weighs collateral quality (treasuries vs crypto-overcollateralized), redemption rights, attestation quality, peg history and liquidity depth. A higher score is not a guarantee: both remain issuer-credit and smart-contract exposures, not insured bank deposits.
What is the difference between DAI and USDY?
+
Dai is issued by Sky (formerly MakerDAO) (Decentralised / Cayman foundation), backed by crypto-overcollateralized, with redemption terms: direct. Ondo US Dollar Yield is issued by Ondo Finance (BVI), backed by treasuries, with redemption terms: gated. Attestation coverage is "onchain" for DAI and "monthly" for USDY.
Which has the bigger market cap, DAI or USDY?
+
DAI is larger at $4.77B in circulating supply, against $2.14B for the other. Over the last 7 days supply moved −0.50% for DAI and +0.08% for USDY.
Are DAI and USDY trading at $1.00 right now?
+
DAI trades at $1.0001 (+0.007% off peg) and USDY at $1.1392 (0.000% off peg). The gap between the two is about 1221.2 basis points, which is the cost you pay when rotating size between them before fees.
Has DAI or USDY ever depegged?
+
DAI: worst recorded deviation −7.4%. USDY: no material depeg recorded in our incident set. Past peg behaviour under stress is the single best available proxy for how a token trades in the next crisis.
Which is better for large institutional size, DAI or USDY?
+
For block size the constraint is exit liquidity and primary redemption, not headline supply. USDY shows deeper on-chain liquidity at $2.17B versus $1.11B. Combine that with the redemption channel — DAI: direct; USDY: gated — and size trades against the primary window rather than the order book where possible.
Can I earn yield on DAI or USDY?
+
DAI currently shows the higher rate at 4.71% via flux-finance · Ethereum, against 3.55% via ondo-yield-assets · Ethereum for USDY. Neither token pays interest by holding it in a wallet: the yield comes from lending, liquidity provision or a wrapped yield-bearing version, each with its own counterparty and contract risk.
Which chains support both DAI and USDY?
+
Both are deployed on 4 shared networks, including Ethereum, Arbitrum, Solana, Osmosis. DAI spans 35 chains in total and USDY spans 11. Bridged supply on a chain is not the same as natively issued supply, and it usually carries the bridge's risk rather than the issuer's.
What does it cost to switch from DAI to USDY?
+
Budget three components: the current price spread of roughly 1221.2 bps, swap or venue fees, and slippage against available depth ($1.11B for DAI, $2.17B for USDY). For meaningful size, redeeming with the issuer and minting the other side is often cheaper than a secondary-market swap.
Is DAI or USDY regulated?
+
DAI is issued from Decentralised / Cayman foundation with onchain; USDY is issued from BVI with monthly. Regulatory status varies by your own jurisdiction and by whether the token is offered under a specific stablecoin regime, so treat this as a starting point for diligence, not legal advice.
