What is Liquity? Guide to LUSD, LQTY & Interest-Free ETH Loans

Liquity is a decentralized protocol that enables interest-free loans using ETH as collateral, issuing the LUSD stablecoin through a one-time fee structure and maintaining its peg via algorithmic mechanisms. With features like governance-free operation, low collateral requirements, and passive income opportunities through LQTY staking, Liquity stands out in DeFi lending—and its upcoming V2 upgrade adds new collateral support and enhanced stability features.

Borrowing money in DeFi shouldn't cost you an arm and a leg in interest payments. That's the core premise behind Liquity, a decentralized borrowing protocol that's gaining serious attention for its unique approach to crypto-backed loans. With the upcoming launch of Liquity V2, it's the perfect time to understand how this protocol works and why it might deserve a spot in your DeFi portfolio strategy.

What Exactly Is Liquity?

Liquity is a decentralized borrowing protocol that allows you to take out interest-free loans using Ethereum (ETH) as collateral. Yes, you read that right – interest-free loans. Instead of ongoing interest payments, you pay a one-time borrowing fee when you create your loan.

The protocol mints LUSD, a USD-pegged stablecoin, against your ETH collateral. This creates what's known as a Collateralized Debt Position (CDP), similar to other lending platforms but with some key differences that make Liquity stand out.

How Liquity Stands Apart From Other Lending Protocols

Several features make Liquity unique in the crowded DeFi lending space:

No ongoing interest – Unlike Aave or Compound where interest compounds over time, Liquity charges just a one-time fee (currently around 0.5%).

Governance-free protocol – There's no DAO or governance token votes that can change the rules. The protocol runs by immutable code.

Minimum 110% collateralization ratio – This is significantly lower than many competitors that require 150% or more, allowing for more capital-efficient borrowing.

Fully decentralized front-ends – Multiple independent interfaces connect to the same underlying protocol, enhancing censorship resistance.

The combination of these features creates a borrowing system that maximizes capital efficiency while minimizing complexity and governance risk.

The LUSD Stablecoin: More Than Just Another Dollar Peg

LUSD is the protocol's native stablecoin that's minted when users borrow against their ETH collateral. Unlike many stablecoins, LUSD maintains its peg through several algorithmic mechanisms rather than centralized reserves:

  • The Stability Pool where users deposit LUSD to earn LQTY rewards and liquidated ETH
  • A Redemption mechanism allowing any user to redeem LUSD directly for ETH at face value
  • An efficient liquidation system that keeps the entire protocol safely collateralized

These mechanisms have proven remarkably effective – LUSD has maintained one of the most stable pegs in DeFi, even during major market crashes.

The LQTY Token: Passive Revenue from Protocol Fees

While governance rights aren't part of the equation, the LQTY token offers something potentially more valuable: a share of protocol revenue. LQTY stakers earn:

  • A portion of borrowing fees (when users open loans)
  • A percentage of redemption fees (when users redeem LUSD for ETH)
  • All this without having to actively manage positions or worry about impermanent loss

This creates a passive income stream for LQTY holders that scales with protocol usage. As more users borrow from Liquity, LQTY stakers earn more revenue.

Liquity V2: What's Changing?

The upcoming Liquity V2 upgrade builds on the success of the original protocol while adding new capabilities:

  • Support for additional collateral types beyond just ETH
  • Enhanced Stability Pool mechanics
  • Improved liquidation processes
  • Maintained commitment to interest-free borrowing

The team has been careful to preserve what made the original protocol successful – simplicity, efficiency, and immutability – while addressing user feedback and market demands.

Real-World Use Cases for Liquity

Beyond the technical details, here's how people are actually using Liquity today:

Leveraging ETH positions – Borrowing LUSD against ETH, then using the LUSD to buy more ETH

Tax-efficient liquidity – Accessing funds without selling ETH and triggering capital gains

Stability Pool yields – Earning LQTY rewards and liquidated ETH by depositing into the Stability Pool

Chicken Bonds – A novel DeFi primitive built on top of Liquity that allows for boosted LUSD yields

These use cases show Liquity isn't just a theoretical protocol – it's being actively used for practical financial strategies.

Risks to Consider

No DeFi protocol is without risks. With Liquity, be aware of:

Liquidation risk – If ETH price drops significantly, positions below 110% collateralization will be liquidated

Smart contract risk – Though the protocol has been extensively audited, all DeFi carries inherent smart contract risk

LUSD depeg risk – While mechanisms exist to maintain the peg, extreme market conditions could test these systems

Always do your own research and only risk capital you can afford to lose.

Frequently Asked Questions About Liquity

What is Liquity Protocol and how does it work?

Liquity is a decentralized borrowing protocol where users deposit ETH as collateral to borrow LUSD stablecoin with a one-time fee instead of ongoing interest payments.

What is the difference between Liquity V1 and Liquity V2?

Liquity V2 expands beyond ETH-only collateral, improves Stability Pool mechanics, and enhances the liquidation system while maintaining the core interest-free borrowing model.

How does Liquity maintain its stablecoin peg?

Through algorithmic mechanisms including the Stability Pool, redemption process, and minimum collateralization requirements – not through centralized reserves.

What are the benefits of using Liquity over other borrowing protocols?

Interest-free loans, lower collateralization requirements, immutable governance-free code, and truly decentralized front-ends.What is the LQTY token used for?

LQTY is used for staking to earn a share of protocol fees rather than for governance, creating a passive income stream for holders.

Whether you're looking to leverage your ETH holdings, access liquidity without selling, or earn passive income through the Stability Pool or LQTY staking, Liquity offers unique advantages worth considering for your DeFi strategy. The upcoming V2 release looks to build on these strengths while expanding the protocol's capabilities.
