ARTICLE SNAPSHOT

Aave is a borrowing, lending, and automated market maker (AMM) protocol hosted
on Ethereum and popular layer-2 EVM blockchains. It is compatible with ETH,
several Ethereum-based stablecoins, and popular ERC-20 tokens. Aave version 3
introduces features like efficiency mode (eMode), portals, and isolation mode,
as well as the Aavegotchi NFTs and Lens Protocol. These features and protocols
give users more control over their assets and how they are utilized by the
protocol, while also allowing them to earn crypto rewards and trade between
different cryptos.

Aave is one of the biggest movers in DeFi when it comes to borrowing and lending
crypto. With Aave V3 up and running, everyone's scrambling to get their assets
onto the newest version of the protocol and get that sweet, sweet DeFi yield.
So, if you're confused by the new features and how they're different from Aave
V2, let's break down this expeditious DeFi protocol.




WHAT IS AAVE?

AAVE VERSION 3 IMPROVES ON THE FEATURES OF VERSION 2 BY GIVING LENDING AND
BORROWERS MORE CONTROL OVER THEIR ASSETS AND HOW THEY ARE UTILIZED BY THE
PROTOCOL.

Aave is a borrowing, lending, and automated market maker (AMM) protocol hosted
on Ethereum and popular layer-2 EVM blockchains. Originally called ETHLend, the
Aave platform's suite of user-friendly multichain features include borrowing
against your crypto assets by depositing crypto as collateral as well as
swapping between different cryptos. Aave V3 refines the protocol with new
features and the creators of the platform are developing an accompanying
decentralized social network.



AAVE TOKEN




The Aave protocol is compatible with ETH, several Ethereum-based stablecoins,
and popular ERC-20 tokens. Aave's native asset is the AAVE token which is a
governance token that can also be staked to secure the Aave protocol and be
utilized in case part of the protocol fails—including anything from smart
contract bugs, failure of the price oracle, or the liquidation of a
collateralized asset experiencing a price crash. Despite its limited utility,
the token is useful because it keeps the platform decentralized by making token
holders absorb the protocol's risk.



LENDING ON AAVE

Aave DeFi users mainly earn money through crypto lending. They deposit crypto
into the platform to let others borrow it in exchange for an APY reward. The
rate of rewards earned by depositing into the protocol varies based on the total
volume deposited and how much is being borrowed. When a larger proportion of
assets is borrowed, the rate goes up. On the flip side, the rate is lower when
there are fewer borrowers.

BORROWING ON AAVE




Crypto deposited into Aave also serves as collateral for borrowing from the
protocol. Borrowers must deposit crypto in order to borrow against it, and the
amount borrowed can't exceed the dollar value of the collateral. If the value of
the collateral drops below the value of the loan, the collateral could get
liquidated and the borrower loses the assets deposited into the protocol.



SWAPPING ON AAVE

Aave also has a swap function where deposited assets can be traded for one
another. Aave swapping uses an AMM function—like Uniswap or Pancakeswap—that
utilizes assets deposited into the protocol as liquidity for exchanging between
different cryptos. So depositing into Aave also means providing liquidity to the
Aave AMM protocol, and even crypto actively serving as loan collateral can be
swapped. 

AAVE A- TOKENS

Aave is designed to be compatible with other DeFi protocols through the use of
a- tokens. These tokens are derivatives representing crypto assets deposited
into the Aave protocol, and they're used to account for all assets in the
protocol across different networks. Those who deposit crypto into the protocol
receive a corresponding a- token in their DeFi wallet which can be utilized to
earn more rewards on other compatible protocols.

For example, if you deposit ETH into the Aave protocol you will receive an equal
amount of Aave Market ETH (amETH). If you swap your deposited ETH for a wrapped
bitcoin (wBTC) using the Aave protocol, you would actually be swapping amETH for
amwBTC, either of which can be withdrawn anytime for ETH or wBTC, respectively.
You can also use amETH to earn rewards in another DeFi protocol that accepts a-
tokens, but removing a- tokens from your wallet prevents you from using them as
collateral and borrowing against them.






AAVE V3 IMPROVEMENTS

Aave version 3 improves on the features of version 2 by giving lending and
borrowers more control over their assets and how they are utilized by the
protocol. The main three features introduced in Aave V3 are efficiency mode
(eMode), portals, and isolation mode. 

EFFICIENCY MODE 




Efficiency mode, or eMode, allows Aave users to maximize their borrowing power
by using correlated assets as collateral. While borrowed assets normally have an
80% threshold against the collateral, eMode allows borrowers to raise this
threshold to 97% without risking liquidation by only allowing assets that are
pegged to the same value as their collateral to be borrowed. 



The best example of eMode is using it to borrow one stablecoin against another
stablecoin, but this can also be used to borrow ETH if the asset serving as
collateral is pegged to the same value, like stETH—a liquid staking derivative
token of ETH. For instance, while Aave V2 limits how much USDC can be borrowed
against USDT, Aave V3's e-Mode removes this restriction since depositing and
borrowing assets pegged to the US dollar has an extremely low liquidation risk. 

PORTALS

Another feature of Aave V3 is cross-chain portals which use a- tokens to let
depositors transfer their assets across different networks within the Aave
ecosystem. This means that Aave V3 also features a bridge function that lets
depositors move assets across all blockchains which host the Aave protocol.
Currently, Aave V3 is compatible with Ethereum as well as popular layer-2
networks like Arbitrum, Avalanche, Fantom, Harmony, Optimism, and Polygon. 

ISOLATION MODE & SILOED BORROWING

The final major feature implemented in the Aave V3 update is isolation mode.
Isolation lets depositors curb liquidation risk by only separating one deposited
asset from other collateral and only allowing stablecoins to be borrowed against
that asset. Another feature called siloed borrowing allows assets to be 'supply
only,' which means they can be deposited but can't be used as collateral. This
allows users to deposit crypto into the protocol and earn APY without any
liquidation risk even if they have an outstanding loan.




FUTURE OF AAVE

Aave has several other developments that are expanding the platform beyond just
being a multichain DeFi protocol. In addition to a decentralized DeFi network,
the Aave ecosystem also includes play-to-earn (P2E) blockchain gaming and even
has a mobile app in the works. There isn't much news on the mobile wallet, but
the Aavegotchi NFTs are minted and the Gotchiverse metaverse has already
launched.

AAVEGOTCHIS AND THE GOTCHIVERSE





Source: gotchiverse.io

Aave's Gotchiverse is a metaverse world on the Polygon blockchain that anyone
can gain access to using the Aavegotchi NFTs. Aavegotchis are procedurally
generated ghost NFTs on the Ethereum blockchain and the supply of Aavegotchis is
potentially limitless since the supply is controlled by the Aavegotchi
decentralized autonomous organization (DAO). Aavegotchi NFTs are summoned
through portals, which are also NFTs that can be purchased using the
Gotchiverse's native GHST token. 

The Gotchiverse is inspired by the Tamagotchis—virtual pet toys which became
popular in the 1990s and early 2000s. Players can earn crypto in the Gotchiverse
by staking DeFi tokens with their Aavegotchi and caring for them daily. Players
are rewarded by updating their Aavegotchi's metadata which makes the NFT more
rare and desirable if it's maintained over time. Aavegotchis have different
values based on their functional and aesthetic features. 

LENS PROTOCOL




Lens Protocol is a Web3 permissionless social networking platform created by
Aave founder Stani Kulechov and his fellow Aave developers. Lens describes
itself as a "social graph." It allows users to compose NFT social media profiles
that are linked to Web3 wallets on the Polygon blockchain. These NFTs will
include an activity history with posts and comments and the protocol will allow
users to trade 'follow' NFTs and choose how their content is monetized.



Lens is created by the same team that created Aave, but the protocol has grown
from a spinoff of Aave into a standalone DeFi social media project with social
aims that stand apart from Aave's goals of providing financial freedom. However,
the common theme is building a system that challenges the status quo by putting
the power in the hands of the creative community rather than having to share
control with centralized entities.
