Aave Review 2025: Decentralized Lending Platform

Aave has become a standout in decentralized finance (DeFi). Founded by Stani Kulechov in 2017, Aave started as ETHLend before rebranding and revolutionizing DeFi. 

Aave's unique features, like flash loans, enable advanced financial strategies without collateral. Its High-Efficiency Mode optimizes borrowing power, ensuring users get the most out of their assets. Robust security measures, including rigorous audits and bug bounty programs, are in place as well.

Governed by the community through the AAVE token, Aave evolves with input from its users, ensuring transparency and inclusivity.

As we go deeper into this Aave review, we will take a look at its features, security protocols, and governance model.

What is Aave

Aave is a DeFiprotocol that allows users to lend and borrow without needing a central intermediary. Founded by Stani Kulechov in 2017 as ETHLend and rebranded to Aave in 2018, the name "Aave" means "ghost" in Finnish, symbolizing its mission to create an open, transparent financial system.

Aave uses an Ethereum-based protocol. Lenders deposit their cryptocurrencies into liquidity pools to earn interest, while borrowers provide collateral exceeding the loan amount to maintain system stability and security.

Aave supports a wide range of cryptocurrencies, allowing it to attract a diverse user base. One standout feature is "flash loans," which allow users to borrow assets without collateral if the loan is repaid within the same transaction block. This innovation has enabled opportunities for arbitrage, collateral swapping, and other advanced trading strategies.

Aave's governance is handled by a decentralized autonomous organization (DAO). AAVE token holders propose and vote on protocol changes, ensuring the platform evolves according to the community's interests.

Aave's total value locked (TVL) exceeded $11 billion as of mid-2024. Its success has led to the development of complementary products and services, such as Aavegotchi, a blockchain-based game, and Aave Pro, a platform for institutional investors.

Aave's commitment to security includes regular audits and collaborations with top security firms. Its robust security measures and transparent operations have earned it a reputation as a reliable and secure DeFi platform. In a world where "with great power comes great responsibility," Aave takes its role seriously.

How Does Aave Work?

Aave operates as a decentralized financial system, allowing individuals to lend and borrow digital assets without a central authority. Lenders earn interest on their deposits, while borrowers pay interest to access funds. This section explores how Aave functions, highlighting key features and innovations.

Aave's core functionalities revolve around lending and borrowing. Users deposit their cryptocurrencies into liquidity pools, becoming lenders, and these pools are available for other users to borrow from. Interest rates for lending and borrowing are determined algorithmically based on supply and demand. For instance, if the demand for borrowing an asset is high, the interest rate increases, encouraging more users to deposit that asset.

Lending on Aave is straightforward. Users deposit their assets into Aave's liquidity pools and earn interest over time. This process is similar to earning interest on a savings account in traditional finance but with potentially higher returns due to the dynamic nature of DeFi. The deposited assets are tokenized into aTokens, which accrue interest in real-time and can be redeemed at any point.

Borrowing from Aave requires users to provide collateral that exceeds the loan's value. This over-collateralization ensures system solvency and reduces default risk. Borrowers can choose between stable and variable interest rates, managing their exposure to market volatility. Stable rates provide predictability, while variable rates might offer cost savings when market conditions are favorable.

Flash loans allow users to borrow assets without providing collateral, as long as the loan is repaid within the same transaction block. This unique capability enables sophisticated financial strategies such as arbitrage, collateral swapping, and self-liquidation. Flash loans showcase Aave's commitment to innovation and flexibility.

Risk Management

Aave employs several risk management mechanisms to protect users and maintain platform integrity. Over-collateralization ensures that borrowers provide collateral worth more than the loan amount, covering potential losses. If a borrower's collateral value falls below a certain threshold, their position is automatically liquidated to repay the loan, maintaining system solvency. Additionally, a portion of the interest paid by borrowers is allocated to a reserve fund, which can cover unexpected losses or bad debt.

Supplying on Aave

When it comes to supplying assets on Aave, one of the key advantages is the platform's wide range of supported assets. Aave offers lending and borrowing options for a far greater list of assets compared to competitors like Compound. This is particularly beneficial for users holding a diverse portfolio of altcoins who want to earn interest on their holdings.

Additionally, Aave operates on multiple blockchain networks such as Avalanche, Fantom and Polygon, demonstrating its interoperability and adaptability in the evolving DeFi landscape. 

How to Supply Assets on Aave

Supplying on Aave is pretty straightforward:

1. Connect Your Wallet: Users need to connect a compatible wallet such as MetaMask or Ledger to the Aave platform.
2. Deposit Assets: After connecting, users select the asset they wish to supply and specify the amount to deposit. The deposited assets are then transferred into Aave's liquidity pools.
3. Receive aTokens: Users receive aTokens, which accrue interest in real time. For example, supplying DAI gives you aDAI. These tokens represent the user's share of the liquidity pool and can be redeemed anytime.
4. Earn Interest: Interest rates are algorithmically determined based on supply and demand. Higher demand for borrowing an asset increases its interest rate, incentivizing more users to supply that asset.

Let's explore this further with the help of an example: 

Suppose you have 1,000 USDT and decide to supply it to Aave. Here’s how it works:

• Connect your wallet to the Aave platform.
• Select USDT and deposit 1,000 USDT into the Aave liquidity pool.
• Receive aUSDT, which are interest-bearing tokens.
• Over time, your aUSDT balance will increase as you earn interest.

Overall, Aave's extensive asset support, multi-chain functionality, and user-friendly interface make it a superior choice for those looking to earn interest on their cryptocurrency holdings.

Borrowing on Aave

Aave's standout feature is its support for flash loans, which allow users to borrow assets without providing any collateral, as long as the loan is repaid within the same transaction block.

This enables sophisticated financial strategies like arbitrage and collateral swapping. Additionally, Aave uses a single-asset risk model, ensuring that a crash in one asset only affects that asset. It also employs a protocol-based liquidation system, which can result in lower penalties for borrowers.

Borrowing on Aave works pretty much like supplying: 

• Connect Your Wallet: Users need to connect a compatible wallet.
• Deposit Collateral: To borrow assets, users must first deposit collateral that exceeds the loan value. This over-collateralization ensures system solvency and reduces default risk. The collateral required depends on the asset's Loan-to-Value (LTV) ratio.
• Select Borrowing Options: After depositing collateral, users select the asset to borrow from supported cryptocurrencies.
• Confirm the Borrowing Transaction: Users confirm the transaction terms. Borrowed assets are transferred to the user’s wallet, and interest starts accruing. If the collateral value falls below a threshold, the position is automatically liquidated to repay the loan.

Let's look at this with the help of an example.

Suppose you have 2 ETH and need to borrow USDT. Here’s how it works:

• Connect your wallet to the Aave platform.
• Deposit 2 ETH as collateral. If the LTV ratio for ETH is 75%, you can borrow up to 1.5 ETH worth of USDT.
• Select USDT from the supported assets and choose between a stable or variable interest rate.
• Confirm the transaction to receive USDT in your wallet. Over time, you will accrue interest on the borrowed amount based on the chosen rate.

Aave V3 Overview

In January 2022, Aave released the technical paper for Aave V3, enhancing features like aTokens and interest rate models to improve its $30 billion peak liquidity.

V3 focused on four key areas:

• Capital Efficiency: Increasing revenue for lenders and allowing borrowers to loan more against the same collateral by optimizing borrowing power, reducing high gas costs on the Ethereum mainnet, and minimizing liquidity segregation.
• Protocol Safety: Implementing advanced defense mechanisms to protect against threats like infinite minting and oracle manipulation.
• Decentralization: Modifying the governance framework to reduce gatekeeping, promoting a more inclusive ecosystem.
• User Experience: Enhancing seamless cross-chain value and liquidity transfers for a more intuitive and accessible platform.
  Aave V3 ensures the protocol's competitiveness and relevance in the evolving DeFi space.

Aave V3 introduced new features and improvements aimed at enhancing efficiency and user experience. Key upgrades include:

Portal

Aave operates across multiple markets, including:

• Ethereum
• Optimism
• Metis
• Arbitrum
• AMM
• Polygon
• Avalanche
• Solana

The Portal feature in Aave V3 enables cross-chain liquidity by using governance-backed bridges like Connext and Hop Protocol. It allows users to supply collateral on one network, such as Ethereum, and borrow funds on another, like Arbitrum or Polygon. The Portal achieves this by burning aTokens on the source chain and minting an equivalent amount on the destination chain, facilitating seamless cross-chain liquidity flow.

Efficiency Mode (eMode)

Efficiency Mode (eMode) in Aave V3 optimizes risk parameters for borrowers using correlated digital assets as collateral, such as different stablecoins or similar tokens like ETH and stETH. 

By recognizing the predictable volatility of these correlated assets, eMode overrides Aave's standard calculations for LTV, interest, and liquidation. This allows users to borrow more capital from the same collateral, increasing capital efficiency by up to 23% in scenarios like stablecoin eMode.

Other Improvements

Aave V3 includes several nuanced improvements:

• Isolation Mode: Approves new tokens as collateral with a debt ceiling and limits access to stablecoins.
• Siloed Borrowing: Restricts borrowing of configured assets to individual loans, preventing them from being included in a basket of borrowed assets.
• Supply and Borrow Caps: Allows designated admins to set caps on individual reserves.
  Repaying with aTokens: Enables users to repay loans using aTokens if the underlying asset is locked in the liquidity pool.
• Configurable Rewards: Supports multiple rewards per token and allows users to claim rewards to different accounts or multiple types of rewards in a single transaction.
• Migration Tool: Provides a tool for migrating positions from V2 to V3, summarizing risk parameters for informed decision-making.

GHO Stablecoin

GHO Stablecoin is Aave's native decentralized stablecoin, designed to offer stability and liquidity within the Aave ecosystem. Pegged to the US dollar, GHO provides a reliable medium of exchange and store of value for users participating in the Aave protocol. This section explores the core concepts, mechanisms, and benefits of GHO Stablecoin.

GHO is minted against various collateral types within the Aave protocol. Users can mint GHO by depositing collateral assets into Aave's liquidity pools, ensuring the stablecoin is fully backed and over-collateralized. This mechanism maintains the stability and value of GHO, ensuring it remains pegged to the US dollar.

GHO's stability is maintained through market arbitrage. If GHO's value exceeds $1, traders will profit by swapping GHO for other stablecoins, bringing its value back to $1. If GHO's value falls below $1, repaying debt with GHO becomes profitable, reducing its supply and helping to restore the peg to $1.

Minting and Redeeming GHO

• Minting GHO: Users deposit eligible collateral assets into Aave, ensuring they meet specific requirements and are over-collateralized. Once deposited, users can mint GHO tokens proportional to their collateral's value.
• Redeeming GHO: Users can redeem GHO by repaying the borrowed stablecoin and unlocking their collateral. This process involves burning the GHO tokens, reducing the supply and maintaining the stablecoin's peg to the US dollar.

Here are a few benefits of the stablecoin

• Stability: GHO maintains a stable value pegged to the US dollar.
• Decentralization: GHO operates without central authority control, leveraging Aave's decentralized infrastructure for transparency, security, and trust.
• Collateral Diversity: GHO can be minted against various collateral types, including different cryptocurrencies supported by Aave, enhancing flexibility.
• Integration with Aave Ecosystem: GHO integrates seamlessly into Aave, enabling its use for borrowing, lending, and participating in liquidity pools, enhancing its utility within DeFi.
• Discount Strategy: Users staking AAVE tokens in the Safety Module (stkAAVE) receive a discount on borrowing GHO, providing an added incentive.
• Arbitrage Opportunities: GHO supports sophisticated financial strategies such as arbitrage, offering additional value for users.

GHO incorporates several risk management mechanisms to ensure its stability and security:

• Over-Collateralization: Each GHO stablecoin is backed by more value in collateral than the stablecoin itself, reducing the risk of under-collateralization.
• Liquidation Mechanisms: If collateral value falls below a threshold, it is automatically liquidated to maintain GHO's stability and peg to the US dollar.
• Transparency and Governance: GHO operates transparently on the blockchain. Governance decisions related to GHO are made by AAVE token holders, ensuring decentralized control and community involvement.
• Facilitators: Managed by the Aave DAO, facilitators play a key role in managing GHO's supply and ensuring smooth operations within the protocol.

The Path to Decentralizing Aave
