Lending protocol UI showing collateral and borrowed amount

DeFi lending protocol interface showing collateral, borrowed amount, and position health, with a twilight blue design.

About this subject

Decentralized lending protocols, such as Aave, Compound, and MakerDAO, have revolutionized access to credit by allowing users to lend and borrow crypto assets without intermediaries. In this interface, the user sees the deposited collateral value (e.g., ETH) and the borrowed amount (like USDC or DAI), along with the health factor indicator. This factor determines whether the position is at risk of liquidation: if it falls below 1, the collateral is sold to cover the debt. The twilight blue hour design may be associated with platforms operating 24/7, as the crypto market never closes. The symmetric and minimalistic composition facilitates quick reading of critical data, essential in a volatile environment. These protocols move billions of dollars in total value locked (TVL) and are audited by firms like Trail of Bits and OpenZeppelin to ensure security.

Frequently Asked Questions

What is the health factor in a lending protocol?

It is a numerical indicator showing the ratio between collateral value and borrowed amount. The higher it is, the safer the position. Below 1, liquidation is imminent.

How does liquidation work in DeFi?

When the health factor drops below 1, liquidators can purchase collateral at a discount and repay the debt, protecting the protocol. The user loses part of the collateral.

What are the main risks of using lending protocols?

Risks include volatility of the collateral asset, smart contract hacks, and price oracle failures. Audits and decentralized insurance mitigate some risks.
