What is Aave?

Aave is an open-source DeFi protocol for crypto lending and borrowing built on the ETH network.

It was launched by Stani Kulechou in 2017 as ETHLend – and was then, the first P2P money market place for lending and borrowing of crypto assets.

However, during the bear season in 2018, ETHLend suffered liquidy issues that it became difficult to match loan requests.

In a bid to restore the platform, the team at ETHLend rebranded to Aave and launched Aave V1 on Jan. 8 2020.

This saw Aave evolve from a P2P to becoming a full pool based protocol; providing expanded financial services than the former.

Moreover, Aave is a Finnish word meaning “ghost” in English, and it goes to imply that Aave is totally decentralized.

The launch of Aave came with full force and brought a lot of liquidity to platform.

To ensure that the Aave ecosystem is running even more efficient, the team behind it launched AAVE V2 around Dec. 2020.

This is a total revamp of what Aave V1 offered.

Aave has become one of the most valuable DeFi projects currently on ground.

For the records, up-to 24 ERC20 tokens are available for lending and borrowing, and over 4B worth of crypto are locked on the platform.

Aave Protocol requires no KYC, and the lending/borrowing processes are being carried out through a smart contract.

In the next section, I will lead you on to the features of Aave. Let’s dive in!

Features Of Aave

With the launch of V2, Aave now includes the following features;

1. Collateral Trading

Aave V2 allows for the trading or the swapping of assets on the Aave network.

This feature primarily allows borrowers to avoid liquidation when their collateral starts to depreciate by trading their assets for a stable coin.

It equally gives the opportunity of swapping collateral into cryptos with high yield at the moment.

2. aTokens

An aToken is issued when you deposit your asset on Aave and are also used for staking on Aave.

They are pegged 1:1 to the value of an underlying asset. For instance, you get aUSDT for depositing USDT on Aave.

More so, based on the example above, it is this your aUSDT that accrues interest in real-time directly in your wallet.

aTokens are burnt after a lender withdraws his asset from Aave.

3. Debt Tokenization

This token is issued to a borrower.

It is a debt accruing token that can be traded on a DEX. This is against the internal debt accounting which we have in Aave V1.

4. Gas Optimization

AaveV2 lowers the cost of transactions up to 50% in some cases.

Also, a native Gas Token Support has been integrated, to help users reduce their transaction costs.

5. Stable and Variable Rate Borrowing

This is an interest rate that specifically applies to borrowers on Aave. I explained it in the next section

6. Credit Delegation

This allows lenders to lend their aTokens to borrowers to earn more interest.

It also an opportunity for borrowers to obtain an uncollateralized loan from lenders.

The enforcement of the loan and its terms are agreed upon between the depositor and borrowers and not Aave.

Moreso, the agreement can either be made off-chain via legal agreements or on-chain via smart contracts.

7. Staking

This feature allows you to stake Aave token on Aave pool.

8. Repayment with Collateral

This allows users to repay their loan using their deposited collateral unlike what we have in Aave V1 – where it is almost impossible to do so.

9. Batch Flash Loan

This was introduced against the flash loan in V1 that only allows users to borrow single crypto at a time.

With this feature made present, borrowers can now obtain a multi-crypto loan in one single loan.

Note: Some of these features are not available on Aave V1.

Do not worry, I will explain the difference between Aave V1 and V2 in the FAQ section.

How Does Aave Work?

Cryptonites who wish to join any of the lending pools on AAVE can do so, by simply connecting their wallets to Aave.

Aave currently has 3 market places;

  • Aave V1
  • Aave V2
  • Uniswap (integrated into AAVE V1)

For the purpose of this article, I will be focusing more on AAVE V2.

On Aave’s pool, lenders earn passively from borrowers interest rate by providing liquidity to the pool.

Borrowers, on the other hand, provide overcollateralized assets in ERC 20 tokens to gain access to loans in cryptos (on interest rate).

Interest accumulated are already displayed on each Aave’s network pool, and they differ from coin to coin.

  • APY (Annual profit yield) for lenders
  • APR (Annual profit return) for borrowers

The interest rate on Aave fluctuates based on market condition.

For example, your interest rate becomes higher when you deposit or borrow a cryptocurrency that is in high demand on Aave at a particular time.

Also, the interest rate may get lower if there is no much demand for it by borrowers in the future.

However, in the case of a borrower, there is an option to choose between a variable or stable interest rate.

Variable interest rate – will rapidly fluctuate based on the market condition on Aave, just like in the example above.

Stable interest rate – is fixed for a short period of time but will follow the trend of the market condition in the long-term.

Let’s have a look at the supported cryptos on Aave.

Supported Cryptos on Aave

Here you have them!


To further understand how AAVE works, let’s take a look at how to lend and borrow on Aave’s network pool.

See below!

How To Deposit and Borrow on Aave

How to Deposit on Aave

You can deposit your crypto assets on Aave either as a lender or borrower.

This is a step by step guide on how to deposit on Aave;

  • Go to Aave, select the crypto you want to deposit, select a “Market place” and click on “Deposit”.

Note: Selecting from the first two market places (as displayed on the screen) will direct you instantly to Aave V1 URL to connect your wallet. However, Aave V2 will take you to the second step in this article.

  • You will redirected to another interface, select Aave V2.
  • Connect your web 3.0 wallet to Aave by selecting from the listed options.

For illustration: I will connect my MetaMask wallet to Aave by choosing “Browser Wallet” to complete the rest of the steps.

  • Once you have connected your wallet, you will be redirected to Aave’s market place. Click on “Deposit” and proceed to deposit your asset into the Aave.

Let’s look at how to borrow!

How To Borrow on Aave

To borrow from Aave, here are the steps;

  • Go to Aave, select the crypto you want to borrow, select a “Market place” and click on “Borrow”.
  • Connect your Wallet to Aave (like we previously did).
  • Click “Borrow” to obtain a loan on the asset you have selected.
  • Set the amount of loan you want to collect, select your interest rate type( either “stable or variable”.
  • You can always change your rate afterwards as many times as you want.


To borrow from Aave, you must deposit your collateral using the same deposit process in this article.

Let’s look at the parameters for issuing loans on Aave!

Aave Risk Framework

Each asset in the Aave protocol has specific values related to its risk. This influences how they are loaned and borrowed.

The table below gives a total rundown of the value placed on each crypto.

AAVE loan rates
  • Collateral: This shows if a crypto can be used as a collateral on Aave or not.

According to Aave,” tokens which risk exposure to single counter-parties cannot be used as collateral”.

  • LTV: This simply stands for “Loan to value”. it represents the maximum amount of currency that can be borrowed with specific collateral.

For example: if you use DAI as collateral, the maximum amount of loan you will get must equal 75% of your DAI.

  • Liquidation Threshold: This is the percentage at which your loan can be liquidated.

For example, a Liquidation threshold of 80% means that if the value rises above 80% of the collateral, the loan is under collateralized and could be liquidated.

Taking a deeper dive, let’s compare Aave with its rival Compound.

Aave Vs Compound

Compound was founded by Robert Leshner in 2018.

It is a lending protocol built as a smart contract in the ETH blockchain, just like Aave.

Compound and Aave are one of the popular protocols on DeFi. Although Aave token (AAVE) ranks higher than (COMP) on Coinmarketcap (Feb 9, 2021).

Both are similar in the sense that they offer overcollateralized loans to borrowers and equally have their native tokens (COMP, AAVE).

However, COMP is used as an incentive to reward both lenders and borrowers on its pool, this is not so with AAVE.

On Aave borrowers can switch their interest rate from “Variable to Stabe”; you can’t do that on Compound.

Again, Aave supports more crypto and offers a higher collateral percentage (75%) than Compound (66.6%).

When compared in terms of user-friendliness, Compound does not have all the sophisticated features and Aave, therefore, it is more user friendly.

(i) Aave V1 will only give you an aToken when you make a deposit.
on Aave V2 you will also receive a token that accrues debt for borrowing on the protocol.
(ii) You can only choose between “stable and variable” interest rates on Aave V1 but Aave V2 allows you to flexibly switch between these two rates at any time.

I have written down the features of V2 in the second subheading of this article. However, if you want to learn more, visit here.
