What is Aave? Aave is an open-source, non-custodial decentralized finance protocol that lets users supply digital assets to liquidity markets, earn interest, borrow against collateral, and manage onchain positions without a traditional bank. It is built from smart contracts rather than its own blockchain, with governance conducted by AAVE holders and the Aave DAO.
How Aave works
Suppliers deposit supported assets into liquidity pools and receive interest-bearing aTokens that represent their positions. Borrowers provide collateral and draw loans from those pools, subject to loan-to-value limits, liquidation thresholds, supply caps, borrow caps, and other governance-approved risk parameters. Interest rates generally change with market utilization.
Aave V3 is deployed across multiple public networks, including Ethereum, Polygon, Avalanche, Arbitrum, Optimism, Base, and Aptos. Its contracts inherit the security and consensus of each underlying blockchain. Aave V4 uses a Hub-and-Spoke architecture, in which shared Liquidity Hubs provide capital while specialized Spokes apply different collateral, borrowing, and liquidation rules. V4 launched on Ethereum in May 2026 and expanded to Avalanche in July 2026.
Aave also supports Efficiency Mode for correlated assets, Isolation Mode for limiting exposure to riskier collateral, and flash loans. Flash loans allow uncollateralized borrowing provided that the loan and fee are repaid within the same transaction. If repayment fails, the transaction reverts.
Why is Aave used?
Aave’s main use is permissionless lending and borrowing. Suppliers can seek yield from lending demand, while borrowers can access liquidity without selling collateral. Applications include leverage, refinancing, market making, stablecoin liquidity, collateral swaps, and short-term capital management.
GHO is Aave’s native overcollateralized stablecoin. It provides a stable-denominated borrowing asset and generates fees for the Aave DAO under governance-approved parameters. Aave Horizon extends the model to qualified borrowers using tokenized real-world assets as collateral while separating permissioned collateral markets from permissionless stablecoin liquidity.
As of the CoinStats snapshot captured on 1 October 2026, AAVE traded at $159.40, with a 24-hour change of -3.49%. Its market cap was $2.46B (rank #56), and 24-hour volume was $538.24M. The circulating supply was 15,434,089 AAVE against a total supply of 16,000,000 AAVE. The all-time high was $661.69, the current price is 75.91% below it.
Who is behind Aave and where is it based?
Aave was founded by Stani Kulechov in 2017 under the name ETHLend. The project initially used peer-to-peer lending before shifting to pooled liquidity. It rebranded as Aave in 2018, and Aave V1 launched in January 2020. In 2020, LEND migrated to AAVE at a ratio of 100 LEND for 1 AAVE.
Aave Labs describes itself as the original author and contributor to the protocol, with Kulechov identified as its founder and CEO. Other contributors and service providers have included BGD Labs, Aave Chan Initiative, Chaos Labs, LlamaRisk, and TokenLogic.
The sources do not confirm a single country or legal entity that operates the Aave Protocol. Aave’s terms state that the protocol is not a company or a product operated by Aave Labs. Aave Labs regulatory materials refer to UK entities including Push Labs Ltd and Push Virtual Assets Ltd, while some service terms use Cayman Islands law. These details do not establish that the protocol itself is a Cayman Islands or UK legal entity. A proposed independent foundation for trademarks and intellectual property has not been confirmed as established.
AAVE tokenomics and security
The stated total supply is capped at 16,000,000 AAVE. The original distribution assigned 13,000,000 AAVE for LEND-holder migration and 3,000,000 AAVE to the Aave Ecosystem Reserve. Reserve tokens can fund incentives, grants, liquidity, and development through governance decisions, so circulating supply can change even though the stated maximum remains fixed.
AAVE is primarily used for governance, delegation, and participation in protocol security systems. The former Safety Module allowed eligible assets to be staked as a potential backstop against deficits. Umbrella is the newer risk-management system, allowing selected aTokens or GHO to be staked for rewards while accepting asset-specific slashing risk. Governance has also approved a buyback program with an annual budget of $50 million. Purchases do not automatically reduce the maximum supply because the documentation does not guarantee token burns.
Aave has no independent validator set or consensus mechanism. Ethereum, Avalanche, and other host networks provide base-layer security, while Aave relies on smart-contract audits, oracle price feeds, collateral requirements, liquidations, governance controls, and emergency measures. These mechanisms reduce risk but cannot eliminate vulnerabilities in contracts, oracles, bridges, governance, or underlying blockchains.
Ecosystem and development
Aave integrates with Ethereum and major Layer 2 networks, Chainlink price feeds and CCIP cross-chain infrastructure, tokenized-asset platforms such as Centrifuge and Securitize, and stablecoins including USDC, RLUSD, and GHO. Horizon’s ecosystem has also included Circle, Superstate, Ripple, Ethena, OpenEden, VanEck, and WisdomTree.
Current development focuses on expanding V4 across additional networks, refining Hub-and-Spoke markets, improving risk automation, developing GHO and Savings GHO, expanding Horizon’s institutional lending products, and building consumer-facing applications. Aave Labs’ acquisition of Stable Finance in 2025 supported that consumer-product strategy. Further work includes AaveKit developer tools, Umbrella, Chainlink SVR liquidation infrastructure, and research into Bitcoin-related vaults.
