KoinlyticsUSDe is the first stablecoin that scales into the billions without using T-bills or fiat reserves. Its backing is a delta-neutral position: staked ETH (LST) plus short ETH perp on centralized exchanges. Users get a $1 peg and, via sUSDe, yields that reach double digits.
Backing mechanics
User deposits 1 stETH worth $3,000. Ethena:
- Holds the stETH (earning ~3% staking yield).
- Opens a $3,000 short ETH perp on Binance/Bybit/OKX/Hyperliquid.
- Mints 3,000 USDe against the resulting delta-neutral position.
The stETH gain when ETH rises is exactly offset by the short's loss. Net exposure = 0.
Where the yield comes from
- Staking yield on stETH: ~3% APR.
- Perp funding: 5-20% APR when positive.
- T-bill yield on cash reserves: ~5% APR.
Total accrues to sUSDe holders (Ethena's yield-bearing wrapper). Historical APR: 8-30%.
Peg maintenance
Whitelisted market makers can mint 1 USDe for $1 of collateral and burn 1 USDe for $1 of collateral. Arbitrage keeps USDe at $1.
The real risks
- Funding flip negative. Ethena pays instead of earns. Yield drops to zero or below. Not fatal but breaks the value prop.
- CEX freeze / insolvency. Ethena's short leg lives on Binance/Bybit/OKX/Hyperliquid. If one fails during a stress event, the hedge is stuck.
- LST depeg. stETH trading below 1 ETH during panic makes the collateral worth less than expected.
- Cascading liquidation on the shorts. Fast ETH rally forces Ethena to unwind at loss.
Reserve fund
Ethena runs a Reserve Fund (currently ~$60M) that absorbs the shortfalls in stressed periods. Adequate for normal drawdowns, uncertain in a 2022-scale event.
