Lending protocol UI showing collateral and borrowed amount

DeFi lending protocol interface displaying collateral ratio, borrowed amount, and position health in real time.

About this subject

Decentralized lending protocols such as Aave, Compound, and MakerDAO have revolutionized access to credit by allowing users to borrow against crypto assets as collateral. In a typical interface, the user sees the deposited collateral value (e.g., ETH or WBTC), the borrowed amount in stablecoins like DAI or USDC, and the position health indicator, often called the 'health factor' or 'collateral ratio.' This critical number determines whether the position is safe or at risk of liquidation: if the health factor drops below 1, the collateral can be sold to cover the debt. Most platforms also display the variable or stable interest rate, maximum allowed loan-to-value (LTV), and real-time asset prices fetched from oracles like Chainlink. The interface is designed to be clear and actionable, with buttons to deposit more collateral, repay part of the debt, or withdraw assets. This design is essential for user safety because the crypto market is volatile and liquidations can happen quickly. In the DeFi ecosystem, these interfaces have become the gateway to intermediary-free financial services, but they require users to constantly monitor their positions to avoid losses.

Frequently Asked Questions

What does health factor mean in a lending protocol?

Health factor is a number indicating the safety of your position. If it's above 1, the position is healthy; if it drops below 1, the position may be liquidated.

How does liquidation work in DeFi lending?

When the health factor falls below 1, liquidators can buy your collateral at a discount to repay your debt, and you lose the deposited assets.

What is the difference between variable and stable interest rates?

Variable rate changes based on pool supply and demand, while stable rate is fixed for a period but may be adjusted in extreme situations.
