Aave is a leading decentralized, non-custodial borrowing and lending protocol that enables users to deposit digital assets into liquidity pools to earn interest and borrow assets using variable or stable interest rates. Originally launched in 2017 as ETHLend by Stani Kulechov, the project raised $17.8 million in an initial coin offering (ICO) before rebranding to Aave in 2018. One of its most innovative features is the flash loan—a type of uncollateralized, instant loan that must be repaid within a single blockchain transaction.
The protocol maintains system stability by requiring all loans (except flash loans) to be over-collateralized. This means the collateral's value must exceed the loan amount. If the collateral value drops below a predefined threshold, it is automatically liquidated to repay part of the debt, ensuring continuous liquidity.
TL;DR
- Aave is a decentralized finance (DeFi) protocol for borrowing and lending digital assets.
- It ranks as the second-largest DeFi protocol by Total Value Locked (TVL).
- Loans are over-collateralized for safety, and a Safety Module acts as a liquidity backstop.
- The native AAVE token is used for governance and staking within the ecosystem.
How Aave Works
Although initially built on Ethereum, Aave has evolved into a multi-chain protocol, operating on networks like Fantom, Avalanche, and others. It supports Ether and various ERC-20 tokens, with all operations automated through smart contracts in a trustless, peer-to-peer manner.
To ensure liquidity, Aave mandates over-collateralization for all standard loans. The Loan-to-Value (LTV) ratio—set at 75% for most assets—determines the maximum borrowing amount against collateral. If a user’s LTV rises above this threshold, their collateral is liquidated.
When users deposit assets into a liquidity pool, they receive aTokens (e.g., aETH for Ether deposits). These aTokens represent the deposited assets and accrue interest in real time. They can be redeemed at any time and also provide holders a share of the fees generated from flash loans.
Interest rates are algorithmically determined based on supply and demand for each asset. High utilization rates often lead to higher returns but come with increased liquidity risk.
The Safety Module is a key security feature where users stake AAVE tokens to provide a backstop for the protocol. In return, they earn staking rewards. This pool is used to cover deficits in extreme scenarios.
Uses of the AAVE Token
The AAVE token is central to protocol governance, giving holders voting rights on proposals and upgrades. Beyond governance, AAVE serves several other functions:
Trading
AAVE can be traded on various cryptocurrency exchanges. Its price is subject to market volatility, making it important to understand the risks involved in trading.
Earning Interest

Safety Module Staking
Staking AAVE in the Safety Module helps secure the network. In return, stakers receive additional AAVE tokens as rewards, creating a dual benefit of supporting the protocol and earning yields.
The History and Evolution of Aave
Aave began as ETHLend, a peer-to-peer lending platform founded by Stani Kulechov in 2017. After an ICO that raised $17.8 million, the project shifted to a liquidity pool model and rebranded as Aave in 2020. The launch of flash loans attracted significant attention, establishing Aave as an innovator in the DeFi space.
Kulechov, who leads Aave Companies, has focused on creating a transparent and inclusive financial system through decentralized technology.
AAVE Tokenomics
AAVE is an ERC-20 token with a total supply of 16 million. It replaced the original LEND token at a conversion rate of 100 LEND to 1 AAVE. The current circulating supply is approximately 14.9 million tokens.
Three million AAVE are reserved in an ecosystem fund controlled by token holders, used to incentivize development and growth. Protocol revenue is also used to buy back and burn AAVE tokens, reducing supply over time.
How New AAVE Tokens Are Created
AAVE is not mined or staked into existence. New tokens are issued only through community governance proposals, typically in response to liquidity shortfalls. If the Safety Module is insufficient to cover a deficit, a proposal to mint new tokens can be voted on by the community.
Competitive Landscape
Aave competes primarily with lending protocols like JustLend and Compound. With a TVL of nearly $6 billion, it is the largest lending platform in DeFi. Key advantages include multi-chain support, higher LTV ratios, and exclusive features like flash loans.
AAVE also leads in market capitalization among its peers, reflecting strong investor confidence.
Partnerships and Investors
Aave has formed strategic partnerships with other major DeFi projects including Balancer, Uniswap, MakerDAO, and Polygon. These integrations enhance its functionality and user experience.
The project has raised $49 million from 16 investors, including notable names like Blockchain.com Ventures and Alameda Research.
