The DeFi market is becoming hotter than ever, especially with the recent incentive programs from multiple blockchains. The TVL (Total Value Locked) across all Dapps (Decentralized applications) is currently $83B, and Aave already impressively accounts for 15% of it.

Moreover, compared to other top-notch lending protocols like Compound or MakerDAO, Aave is receiving the highest revenue. On a daily basis, Aave is earning about $2.34M, while Compound and MakerDAO are getting only $1M and $142K, respectively. In fact, the daily revenue of Aave is currently only behind Uniswap.

Aave Overview

Aave is a liquidity-based Lending protocol. Originated as a decentralized peer-to-peer lending platform (ETHLend), Aave revamped to a pool-based one. 

Instead of forming a direct relationship between lenders and borrowers, Aave involves the participation of both through liquidity pools, thus diversifying the options and automating the process. 

Some notable points before using Aave

Aave currently supports 3 markets: Aave native market, AMM market, and Aave Polygon market. You can switch between them for the best experience.

Aave Protocol has been audited by Trail of Bits, Open Zeppelin, Consensys Diligence, Certik, Peckshield, Certora and Sigma Prime.

In addition, Aave holds a bounty program that rewards people who find bugs in their product/smart contract. Therefore, using Aave is extremely secure.

Aave provides the “Flash Loan” feature that can diversify users’ options to trade, including their collateral assets.

If you borrow on Aave, you have to constantly track your collateral position to avoid being liquidated.

When you deposit assets into Aave, you will receive the corresponding aToken. The number of aToken in your wallet will increase over time; hence, you can earn interest by simply holding that aToken in any wallet.

FAQ about Aave

How much should I borrow?

To avoid liquidation, you should borrow only a reasonable amount. Depending on the assets that you are borrowing, there will be different Liquidation Ratios and Collateral Ratios. I recommend that you keep the Liquidation Price at about 50% (for normal tokens) and 60-65% (for stablecoins) of that asset’s market value. This is a pretty safe threshold to borrow assets.

For example: If I borrow Aave (a normal token) at $280, I will adjust the amount of Aave I borrow so that its Liquidation Price will be around $140 (50%). 

However, remember that this number should only be treated as an advisable standard. You should adjust the amount based on the assets you are borrowing and the assets you are collateralizing, considering its price fluctuation and price spread.

How much can I earn by lending/supplying?

Depending on the protocol you are using and the asset you are depositing, the APY will be different. 

Do remember that the APR (APY) you earn by lending is usually much lower than that by farming/staking. Conventionally, the APR on lending protocols ranges from 1% to 3%.

You should check all the possible yields on different platforms and protocols to make the most profitable decision.

Do I have to lock my assets when lending/supplying?

No, you don’t. You can withdraw your assets anytime you want, given that you are not borrowing any assets and/or having any debt.

How much do I have to pay after borrowing?

The borrowing fee varies depending on the assets you are borrowing, and the application you are using. Although some assets are supported with a 0 borrowing fee, the number usually ranges from 5-7%.

You can pay this fee in multiple assets based on the list that the protocol supports.
