USDE vs USDS
Ethena USDe and Sky Dollar, compared on the things that decide whether you get your dollar back. Live data, updated continuously.
30-day peg gap and USDE/USDS spread
Loading price history…
A synthetic dollar built from staked crypto collateral hedged with short perpetual futures. It is not a fiat-backed stablecoin: the peg depends on funding rates, exchange solvency and hedge execution.
Verdict band: Adequate
Sky's upgraded dollar, overcollateralised on-chain by crypto assets and tokenised real-world credit. Collateral is verifiable on-chain in real time; a large share is now allocated to Treasury-backed exposure.

"Matters" is our weighting of how much each dimension typically drives a real allocation decision. Sort any column to re-rank the tradeoffs by what matters to you.
The short answer
USDS scores higher on safety (87 vs 72), driven mainly by collateral quality and disclosure. USDE has deeper tracked liquidity ($2.23B), which is what determines whether you can exit at size. USDS currently earns up to 13.90% — 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.

USDE vs USDS: frequently asked questions
Is USDE or USDS safer?

The score weighs collateral quality (crypto-overcollateralized vs delta-neutral), 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 USDE and USDS?
+
Ethena USDe is issued by Ethena Labs (BVI), backed by delta-neutral, with redemption terms: gated. Sky Dollar is issued by Sky (formerly MakerDAO) (Decentralised / Cayman foundation), backed by crypto-overcollateralized, with redemption terms: direct. Attestation coverage is "monthly" for USDE and "onchain" for USDS.
Which has the bigger market cap, USDE or USDS?
+

Has USDE or USDS ever depegged?
+
USDE: worst recorded deviation −2.9%. USDS: 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, USDE or USDS?
+
For block size the constraint is exit liquidity and primary redemption, not headline supply. USDE shows deeper on-chain liquidity at $2.23B versus $2.05B. Combine that with the redemption channel — USDE: gated; USDS: direct — and size trades against the primary window rather than the order book where possible.
Can I earn yield on USDE or USDS?
+
USDS currently shows the higher rate at 13.90% via yearn-finance · Ethereum, against 12.46% via accountable · Robinhood Chain for USDE. 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 USDE and USDS?
+
Both are deployed on 4 shared networks, including Ethereum, Solana, Base, Arbitrum. USDE spans 25 chains in total and USDS spans 4. 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 USDE to USDS?
+
Budget three components: the current price spread of roughly 0.5 bps, swap or venue fees, and slippage against available depth ($2.23B for USDE, $2.05B for USDS). For meaningful size, redeeming with the issuer and minting the other side is often cheaper than a secondary-market swap.
Is USDE or USDS regulated?
+
USDE is issued from BVI with monthly; USDS is issued from Decentralised / Cayman foundation with onchain. 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.
