Fees: One-time borrow/redemption fees (v1); interest-rate markets in v2
Liquity appeals to users prioritizing decentralization and immutable, admin-free contracts for ETH-backed stablecoin borrowing. Expect modest liquidity and the quirks of its redemption design. Not financial advice.
What Liquity Is
Liquity is a decentralized borrowing protocol that lets users take out stablecoin loans against ETH collateral, with its original v1 built as immutable, governance-free smart contracts that no team can upgrade or pause. Launched in 2021, v1 issues the LUSD stablecoin through interest-free borrowing, using a stability pool and redemption mechanism instead of traditional interest to keep the system solvent. Its newer v2 introduces user-set interest-rate markets, extending the model while keeping decentralization central.
How It Scores Where It Counts
Liquity earns 8.1, and its identity shows in the criteria. Security and audits (8.5) and transparency and track record (8.5) are its strongest marks, reflecting a clean record since launch and the trust-minimizing choice of immutable, admin-free contracts. Collateral and risk management (8) and rates (8) are solid — interest-free v1 borrowing and a novel stability-pool liquidation design are genuinely differentiated. Liquidity is the clear weak point at 7, since LUSD depth is modest compared with larger stablecoins and money markets.
Costs and Fees
Liquity's cost model is unusual. In v1, borrowing is interest-free; instead you pay a one-time borrowing fee when you draw a loan and a redemption fee applies when LUSD is redeemed against troves. v2 moves toward interest-rate markets where borrowers effectively set or accept a rate. This structure can make v1 attractive for longer-term borrowers who want to avoid compounding interest, though the redemption mechanic is the trade-off that keeps the peg honest.
The Main Caveat
The defining risk is the redemption design: when LUSD trades below peg, the lowest-collateralized troves can be redeemed against and effectively closed, which can surprise borrowers who do not keep a comfortable collateral buffer. On top of that, v1 supports only ETH collateral, limiting flexibility, and LUSD liquidity is modest, so large positions may face more slippage than on bigger platforms. The protocol's overall scale is smaller than the leading money markets.
Who It's For
Liquity appeals to users who prioritize decentralization and immutability — no admin keys, no upgrade risk — for ETH-backed stablecoin borrowing, and who accept modest liquidity and the redemption quirks in return. It is well suited to self-reliant borrowers comfortable managing collateral ratios and understanding how redemptions work. Those who need multi-asset collateral or deep stablecoin liquidity should look elsewhere. Not financial advice.
Overall 8.1 / 10 — the weighted average of the criteria above. How we score →
- + Immutable, governance-free v1 contracts remove upgrade/admin risk
- + Interest-free borrowing (v1) with a novel stability-pool liquidation model
- + Strongly decentralized: ETH collateral and censorship-resistant frontends
- + Clean security record since launch
- − ETH-only collateral (v1) limits flexibility; LUSD liquidity is modest
- − Redemptions can close the lowest-collateral troves unexpectedly
- − Smaller overall scale than top money markets
Is Liquity safe?
+
Liquity scores 8.5 for security and audits in our review and has kept a clean record since launch. Its v1 contracts are immutable and governance-free, which removes upgrade and admin-key risk that many protocols carry. The trade-offs are the redemption mechanism and ETH-only collateral in v1, plus the usual smart-contract and liquidation risks inherent to any DeFi borrowing.
How does Liquity redemption work?
+
Redemption lets anyone swap LUSD for its dollar value in ETH by drawing against the lowest-collateralized troves, which helps hold the peg. The catch is that if your trove is among the least collateralized, it can be redeemed against and effectively closed, so borrowers should keep a healthy collateral buffer. It is the main quirk we flag in our review.
What are Liquity's fees?
+
In v1, borrowing is interest-free; instead you pay a one-time borrowing fee at draw and a redemption fee applies when LUSD is redeemed. v2 introduces interest-rate markets where a borrowing rate applies over time. We score rates 8, reflecting a genuinely differentiated and often cost-effective model for longer-term borrowers.
What collateral does Liquity accept?
+
Liquity v1 accepts ETH only, which is a deliberate choice that supports its strong decentralization but limits flexibility versus multi-collateral platforms. v2 broadens the design with interest-rate markets. If you need to borrow against a range of assets, this narrow collateral focus is a meaningful limitation.
Is Liquity good for decentralized borrowing?
+
For users who prize decentralization, it is one of the purest options, rated 8.1 with top marks for its immutable, admin-free architecture. The trade-offs are modest LUSD liquidity, ETH-only v1 collateral, and the redemption mechanic. Whether it suits you depends on your priorities; this is not financial advice.
