The Aave protocol is an open-source decentralized finance protocol built on the Ethereum blockchain. It uses a set of smart contracts to automate borrowing and supplying tokenized assets on multiple markets. The protocol facilitates the ability for users to borrow and supply cryptocurrency assets across Ethereum, Polygon, Avalanche, and other EVM blockchains by posting collateral.[1][2]

Based on total value locked, Aave is the top lending protocol in decentralized finance.[3]


Aave Protocol was released on the Ethereum Mainnet in 2020 by Stani Kulechov. It was the second iteration of a decentralized lending protocol and followed in the footsteps of ETHLend, the first decentralized financial marketplace that used smart contracts to facilitate peer-to-peer lending agreements.[4] In 2020, Aave transferred ownership of the protocol over to its community, establishing the Aave Decentralized Autonomous Organization (DAO).[5] Changes to the protocol are voted on by the holders of a native cryptocurrency and governance token called AAVE, and then executed by a group of developers.[6] The market capitalization for the AAVE token is over USD 800 million.


Aave Protocol allows users with a crypto wallet to supply and borrow cryptocurrency assets without third-party intermediaries such as banks and brokerages. Users earn interest by supplying cryptocurrency assets into different liquidity pools. In turn, suppliers can use their crypto assets as collateral to borrow at stable or variable interest rates.

Aave V1[edit]

Aave V1 included innovations such as “flash loans”, a DeFi transaction in which a user can borrow crypto assets from the protocol without also being a supplier given the way in which the transactions work such that the borrow and repayment occur within the same block.

Aave V2[edit]

Aave V2 was deployed December 2020 and supports Ethereum natively, plus Polygon and Avalanche. V2 introduced flash liquidations, repayment with collateral, native credit delegation and debt tokenization amongst other capabilities.

Aave V3[edit]

Aave V3 launched in March 2022 and originally supported only Ethereum layer 2 networks and other layer 1 blockchains including Arbitrum, Avalanche, Fantom, Harmony, Optimism, and Polygon.[10][11]

Institutional Adoption[edit]

Aave Arc[edit]

In July 2022, 30 fintechs and institutions joined Aave Arc, an institutional version of its lending protocol that utilizes smart contracts to restrict access to permissioned entities.[12]

JP Morgan[edit]

JPMorgan Chase executed its first trade on a public blockchain using a modified version of the Aave Protocol.[13] The first live cross-border transaction used the Layer 2 Ethereum blockchain, Polygon, to trade tokenized cash deposits and was facilitated by the Monetary Authority of Singapore's (MAS) as part of a pilot program to "explore potential DeFi applications in wholesale funding markets."[14]


Aave was given an Electronic Money Institution license in July 2020 by the U.K.'s Financial Conduct Authority (FCA).[15][16]
