USDe is Ethena's delta-neutral synthetic dollar, carrying funding-rate and exchange-venue risk; USDS is Sky's over-collateralised stablecoin with a governance-set savings rate. Decentralized Finance Publication compares mechanisms, yield paths and risk surfaces below — educational research, not a recommendation to hold either asset.

How to compare two stablecoins
Every stablecoin quotes at a dollar in calm markets, so the quote tells you nothing. What distinguishes them is the mechanism holding the peg and what that mechanism does when it is tested — and those differ far more than the shared $1.00 suggests.
- Backing. Cash and Treasuries with a custodian, crypto collateral in over-collateralised positions, or a hedged derivatives position. Each fails in different conditions.
- Redemption. Who can redeem at par, in what size, and how quickly. A peg defended only by secondary market trading is weaker than one defended by redemption.
- Depeg history. Whether it has broken before, how far, and whether it recovered on its own or because someone stepped in.
- Censorship surface. Whether the issuer can freeze addresses. A feature for compliance, a risk if you assumed the asset was unseizable.
- Yield source, where it pays yield. Reserve interest, borrower demand and funding-rate capture are three different risks wearing the same label.
What goes wrong with either choice
- Depeg. A stablecoin at $0.97 has lost 3% of principal, and some breaks have been permanent.
- Reserve or counterparty failure for fiat-backed designs — custodian, bank, or redemption policy.
- Collateral and liquidation failure for crypto-backed designs during fast moves.
- Regulatory action, including address freezes on centralised issuers.
- Contagion: stablecoins are collateral throughout DeFi, so a break propagates well beyond its holders.
