LUSD is a fully decentralized, ETH-backed stablecoin issued by the Liquity protocol. It maintains a soft peg to the US dollar through over-collateralization — users must deposit at least 110% in ETH to mint LUSD — and hard redemption guarantees: LUSD can always be redeemed for $1 worth of ETH directly from the protocol. Unlike DAI or algorithmic stablecoins, LUSD has no governance token control over monetary policy and no admin keys that can change the rules.

How It Works
Users open “Troves” (collateral positions) on Liquity, depositing ETH and minting LUSD against it. The minimum collateral ratio is 110%, but users typically maintain higher ratios to avoid liquidation. If a Trove falls below 110%, anyone can liquidate it.
Hard peg mechanisms — both directions:
- Below $1: Arbitrageurs can redeem LUSD for exactly $1 worth of ETH from the riskiest (lowest-collateral) Troves. This burns LUSD and reduces supply.
- Above $1: Users can mint LUSD by depositing ETH and sell it on the market. This increases supply.
This two-sided hard peg is Liquity’s key innovation: because redemptions and minting both use real ETH at exactly $1, the peg has a hard floor and ceiling, not just a soft incentive structure.
Stability Pool
Liquity maintains a Stability Pool of LUSD deposited by users. When a Trove is liquidated, the Stability Pool absorbs its debt (LUSD is burned) and receives the liquidated ETH (typically at a slight discount, providing profit to depositors). This prevents cascading liquidations from destabilizing the peg.
No Governance, No Admin Keys
LUSD’s parameters — minimum collateral ratio, redemption fees, borrowing fees — are set at launch and cannot be changed. There is no governance vote, no multisig, no upgrade mechanism. This eliminates governance attack risk and makes the system more predictable, at the cost of adaptability.
History
- 2021, April — Liquity launches on Ethereum mainnet. LUSD becomes the first stablecoin with a hard ETH redemption guarantee.
- 2022, May — Terra/Luna collapse. LUSD maintains its peg throughout, demonstrating the advantage of hard-collateral designs over seigniorage models during systemic stress.
- 2023, March — USDC briefly depegs due to SVB. LUSD (pure ETH-backed, no USDC collateral) is unaffected.
- 2024 — Liquity V2 launches with multi-collateral support. Original protocol (V1) continues operating in parallel.
- 2025 — LUSD supply has remained between $200M–$700M, smaller than DAI but consistently pegged. Use case consolidates around censorship-resistant, governance-free stable collateral.
Common Misconceptions
“LUSD works the same as DAI.”
Key differences: DAI is governed by MKR token holders who can change parameters, accepts multiple collateral types including USDC, and has a soft peg mechanism. LUSD has immutable parameters, accepts only ETH, and has a hard redemption peg. Their failure modes are different.
“LUSD is completely risk-free.”
LUSD carries smart contract risk (bugs in immutable code cannot be patched), ETH price risk (a sudden ETH crash could trigger mass liquidations), and oracle risk. No stablecoin is risk-free.
“Liquity has a governance token.”
LQTY is a secondary token that earns protocol revenue, but it does not control LUSD’s monetary parameters. LQTY holders cannot change fees, ratios, or rules — the system is non-upgradeable.
Criticisms
- Immutability cuts both ways — if a critical bug is discovered, it cannot be patched.
- Single-collateral (ETH only) makes LUSD tied to ETH’s volatility; large ETH drawdowns require over-collateralized users to manage positions actively.
- Redemptions punish the lowest-collateral borrowers unpredictably — if LUSD trades below $1, your Trove may be redeemed against without notice.
Social Media Sentiment
LUSD has a strong following among DeFi-native users who prioritize censorship resistance and neutrality over yield. On r/ethfinance and DeFi Discords, LUSD is frequently cited as the “purest” decentralized stablecoin. After the USDC depeg in 2023, LUSD adoption discussions surged. The main community criticism is Liquity’s rigid parameters making the system hard to adapt when conditions change.
