Q & A

What is Aave and how does it relate to traditional banking?

Aave is a decentralized finance application that allows people to lend and borrow cryptocurrencies, similar to how traditional banks operate but using cryptocurrencies as the asset. It uses smart contracts to automate the lending and borrowing process and determines lending rates algorithmically.

What is the role of the Aave token in the platform?

The Aave token is an Ethereum token that powers the governance on the Aave platform. Token holders get to vote on changes to the application, making it a key component in the platform's decision-making process.

Why did the developers overhaul Ethlend to create Aave?

The developers overhauled Ethlend to create Aave due to two main problems faced by Ethlend: liquidity issues and the manual process of matching borrowers to lenders. Aave automates this process using smart contracts, improving efficiency and user experience.

How does Aave utilize smart contracts in its operations?

Aave uses smart contracts to automate the lending and borrowing process. Lenders can deposit money into a smart contract to earn interest, and borrowers can deposit collateral into another smart contract to borrow funds. The platform uses algorithms within these contracts to determine loan rates based on liquidity.

What is the significance of being over-collateralized in Aave loans?

In Aave, to borrow a certain amount of cryptocurrency, users must provide more collateral than the amount they wish to borrow. This is to mitigate risk in case the value of the collateral decreases, ensuring that lenders are protected even if the borrower defaults.

Can you explain the liquidation threshold in Aave?

The liquidation threshold in Aave is the point at which the platform automatically sells the borrower's collateral to cover the loan if the value of the collateral falls below a certain percentage of the loan value. This protects lenders from losing money due to default.

How does leveraging work with Aave?

Leveraging in Aave involves borrowing against deposited crypto to increase one's position in the market. For example, by depositing and borrowing against Ethereum, a user can increase their holdings and potentially amplify gains if the price of Ethereum rises.

What are flash loans on Aave and how do they work?

Flash loans on Aave are a feature that allows users to borrow large amounts of cryptocurrency without providing collateral. However, these loans must be repaid within the same blockchain transaction block they were borrowed in, making them suitable for quick, high-volume trading strategies.

What happens if a borrower defaults on a loan in Aave?

If a borrower defaults on a loan in Aave, the platform's smart contracts automatically liquidate the borrower's collateral to repay the lender, ensuring that the lender does not suffer a loss.

How does the repayment process work for loans on Aave?

Aave loans do not have a fixed repayment schedule. Borrowers can repay their loans over an undefined period as long as their position remains safe. However, accrued interest will grow over time, which could lead to the borrower's collateral being liquidated if the health factor decreases significantly.
