Backing
Mechanism and reserves
Backing
ETH only, with a 110% minimum collateral ratio (lowest in DeFi). The Stability Pool absorbs liquidations using deposited LUSD, paying liquidators a ~10% reward.
Mint / redeem
Open a Trove with ETH, mint LUSD. Redeem LUSD against the lowest-collateralization Trove at any time for 1 USD of ETH (minus a small redemption fee).

Real-world use
- ›Censorship-resistant DeFi savings
- ›ETH-backed loans with no governance risk
- ›Maximally decentralized payments
Regulation and compliance
Immutable protocol cannot pursue EMT authorization.
- !The 110% LCR is sometimes called too aggressive — extreme ETH volatility tests Stability Pool absorption.
Specific risks
- ● ETH price tail risk in liquidation cascades
- ● Smart-contract risk (mitigated by immutability)
- ● Low liquidity vs major stablecoins
