1. What Is Aave (AAVE)?
Aave is the world's largest decentralized lending and borrowing protocol. Its name means ghost in Finnish. Stani Kulechov started the project as ETHLend in 2017, and it rebranded to Aave when V1 launched in 2020.
Aave's core concept is simple: deposit cryptocurrency as collateral to earn interest, and borrow other cryptocurrencies up to a proportion of that collateral. It resembles bank deposits and loans, but smart contracts automate everything without a central institution. The guide places it first among DeFi protocols by total value locked (TVL), with more than approximately $15 billion deposited.
Aave is considered one of DeFi's leading blue chips. The guide notes that it had not experienced a major protocol-level hack since DeFi Summer in 2020. This security record is also an important source of confidence for institutions entering DeFi.
📊 AAVE Key Facts

2. Core Technology
① Pool-Based Lending
Aave uses liquidity pools rather than a peer-to-peer model. Depositors add assets to a pool, and borrowers take loans from it. Interest rates are set algorithmically according to the pool's utilization rate. High utilization raises rates to discourage borrowing; low utilization lowers rates to encourage it.
② Flash Loans: Instant Uncollateralized Borrowing
A flash loan is described here as one of DeFi's most innovative features, pioneered by Aave. You can borrow, use, and repay millions of dollars without collateral within a single transaction. If repayment is not completed before the transaction ends, the entire transaction automatically reverts.
Major uses of flash loans include:
- Arbitrage: Exploiting price differences between decentralized exchanges
- Collateral swaps: Replacing existing collateral with another asset in one operation
- Self-liquidation: Closing your own position before forced liquidation
- Leverage changes: Adjusting leverage in a single transaction
③ Aave V3: Maximizing Efficiency
Key features of V3 (2022):
- E-Mode (Efficiency Mode): Allows borrowing ratios up to 97% for assets in the same category, such as stablecoins
- Isolation Mode: Isolates risky new assets to contain protocol-wide risk
- Portal: Moves liquidity between chains, described here as using Arbitrum liquidity on Optimism without a bridge
3. The GHO Stablecoin
GHO is an overcollateralized decentralized stablecoin issued through Aave. It resembles MakerDAO's DAI but has several differences:
- Mint GHO directly using collateral deposited in Aave
- Borrowing interest flows directly into the Aave DAO treasury, generating protocol revenue
- Holders of stkAAVE, or staked AAVE, receive discounts on GHO borrowing interest
- A facilitator system allows various institutions to participate in GHO issuance
💡 AAVE's Revenue Model
Aave has one of DeFi's strongest revenue models: ① the protocol's share of lending fees, ② flash-loan fees (0.09% in this guide), ③ GHO borrowing interest, and ④ liquidation fees. AAVE is both a governance token and an asset supported by real cash flow.
4. Tokenomics
- Total supply: 16 million AAVE, among the smallest supplies in the industry
- Circulating supply: Approximately 14.9 million AAVE, or 93%
- Safety Module: Staking AAVE as stkAAVE serves as protocol insurance, with approximately 6–8% APY
- Inflation: None; fixed supply
- Buybacks: Proposals to buy back AAVE using protocol revenue have been discussed since 2024
5. Multichain Presence
Aave is one of the most widely deployed DeFi protocols, operating on more than 10 chains: Ethereum, Polygon, Arbitrum, Optimism, Avalanche, Base, BNB Chain, Fantom, Metis, Gnosis, and others. Governance and risk parameters are managed independently for each chain.
6. Investment Outlook
Positive Factors
- First in DeFi TVL: Established security plus the largest liquidity creates a substantial competitive moat
- Real revenue: Actual cash flow from lending fees, flash loans, GHO interest, and more
- Very limited supply: 16 million is among the smallest supplies of DeFi tokens
- Institutional adoption: Aave Arc's KYC pools support institutional entry into DeFi
- GHO growth: An additional revenue source in the stablecoin market
Negative Factors
- Regulatory risk: Potential for tighter regulation of DeFi lending
- Smart-contract risk: Large TVL makes the protocol a hacking target
- Competition: Rival protocols such as Compound, Morpho, and Spark
- Fork risk: Aave's open-source code allows competing forks to emerge
7. Risks
⚠️ Check Before Investing
• AAVE has experienced declines from its $661 all-time high.
• Smart-contract and regulatory risks remain.
• The guide recommends keeping the investment within 10% of a portfolio.
