Liquity USD: What It Is, How It Works, and Why It Matters in DeFi

When you hear Liquity USD, a decentralized, interest-free stablecoin pegged to the US dollar and built on Ethereum. Also known as LUSD, it’s one of the few stablecoins that doesn’t rely on centralized reserves or corporate backing. Unlike USDT or USDC, Liquity USD isn’t issued by a company holding bank deposits. Instead, it’s created by users who lock up Ethereum as collateral in a smart contract called a Collateralized Debt Position, a vault where users deposit ETH to borrow LUSD without paying interest. This system is called a CDP, and it’s the engine behind Liquity’s entire design.

Liquity USD stands out because it charges no interest. Instead, users pay a one-time stability fee when they open a position, and the system automatically rebalances if ETH’s price drops too far. If your collateral value falls below 110%, your position gets liquidated—meaning someone else can buy your ETH at a discount to pay off your LUSD debt. This keeps the system solvent without needing lenders or middlemen. Liquity also lets users redeem LUSD for ETH at face value, which helps maintain the $1 peg even during market stress. It’s a simple idea, but it works because it removes complexity: no interest, no oracle reliance, no governance votes for basic operations.

People use Liquity USD to get cash without selling their ETH, to leverage positions, or to hedge against crypto volatility. It’s popular among DeFi traders who want stable exposure without giving up their crypto holdings. The system runs entirely on Ethereum, so you need an Ethereum wallet like MetaMask and some ETH to pay for gas. It’s not for beginners who don’t understand collateral ratios or liquidation risks—but if you’ve used Uniswap or Aave before, Liquity feels familiar. You’re not lending or borrowing in the traditional sense. You’re locking, borrowing, and managing risk with code.

What you’ll find below are real-world reviews, technical breakdowns, and risk analyses of Liquity USD and similar DeFi tools. Some posts compare it to other stablecoins. Others show how to use it safely, avoid liquidations, or combine it with yield strategies. There’s no fluff here—just clear, practical insights from people who’ve used it, lost money on it, or built around it. Whether you’re thinking of borrowing LUSD or just trying to understand why it matters in DeFi, these posts will help you cut through the noise.
