About

Aave

Aave is the leading decentralized, non-custodial lending protocol on Ethereum and 12+ other networks. Users can supply crypto assets to earn variable interest, or borrow assets by providing overcollateralized positions — all governed by smart contracts with no intermediary.

Launched in 2020 (originally as ETHLend in 2017), Aave has processed over $71 trillion in cumulative deposits and currently holds $14.5B in total value locked. The protocol is governed by AAVE token holders, who in April 2026 voted to redirect 100% of protocol revenue to stakers — a landmark moment for the AAVE token economy. Aave v4, launched in 2026, introduces a modular hub-and-spoke architecture and expansion into real-world credit markets.

What Users Say

DeFi Veteran
★★★★★

"Been using Aave since v1. The v4 architecture is genuinely better — more efficient collateral utilization and the GHO integration makes the whole system more cohesive."

Yield Farmer
★★★★★

"The April 2026 governance vote to redirect 100% of revenue to AAVE stakers was a game-changer. The Safety Module now makes economic sense for long-term holders."

Cautious DeFi User
★★★★☆

"Excellent protocol, but the health factor dashboard needs attention. Had a close call during a volatile market. Understand liquidation risk before you borrow."
