Founded in 2017, Aave is a Switzerland-based DeFi lending protocol. The platform is committed to providing community-led decentralized financial services. By combining Ethereum utility and complex decentralized technology, Aave has skyrocketed in popularity.

Being a vastly attractive sector of blockchain technology, DeFi (Decentralized Finance) aims to dethrone regular financial institutions by actively supporting crypto development. Aave is a project designed to let users lend and borrow digital crypto assets via its platform.

Aave consists of smart contracts that successfully handle all matters related to security, trust, open-sourceness, etc. Aave works in a user-friendly way: via utilizing protocols, users are able to deposit assets and earn interest in return; whereas other participants have an option to pay interest fees in order to borrow cryptocurrency from the pool of deposited funds.

As mentioned above, the DeFi protocol runs on ETH, meaning that Aave is compatible with EVM tokens. At the time of writing, the platform has roughly $6,300,000,000 liquidity locked within the network’s multiple services.

How does Aave work?

Originally called ETHLend, Aave was released through an initial coin offering and became an instant success. After its rebranding and completely revamping the concept of a DeFi lending protocol, Aave was initiated as an independent project in 2020.

The platform’s innovative technology implies that loans are taken out of a pool of assets instead of a stand-alone lender. The interest rate of a specific pool largely depends on the so-called “utilization rate”, meaning the more deposits are made in a pool, the higher its interest rate. This also boosts liquidity providers’ engagement in low-interest pools.

Through Aave, users can take out loans, borrow against the collateral across Aave’s multiple networks, and participate in the platform’s governing decisions.

What are flash loans?

Based on the ETH network design, a flash loan is a popular feature on Aave. Flash loans are rapidly executed (there is no need to supply collateral) and repaid within the same ETH transaction (+ a small fee). This is usually done in a matter of 13 seconds. If the borrower doesn’t follow the exact requirements, the transaction is therefore canceled. In order to take a flash loan, developers have to build specific smart contracts with the help of the instructions given here.

As the flash loan is reversed, it is also removed from the blockchain history. As the Aave team is saying, flash loans do not have an analogy in the real world, therefore it requires some basic understanding. It is also required that developers have strong programming skills before taking out a flash loan.

What is an AAVE token?

Being a native and utility token for the platform, $AAVE is among the most popular DeFi tokens on the market. Initially known as $LEND, the token was sold via an ICO of $16 million to help fund the startup. As of October 2020, the assets were turned into $AAVE - an ERC-20 token. $AAVE can be earned through buying (click here to check the list of markets) or staking, which is carried out within the platform’s “Safety Module”. In the case of token deficiency (a shortfall event), those affected by it can get up to 30% of the safety module paid back.

It is worth mentioning that the DeFi lending protocol also supplies aTokens, which are issued to lenders in order to collect interest on deposits. This is a different type of token, not to be confused with the native asset of the platform.
