Aave V4 is live: what changed
Aave V4 launched on Ethereum mainnet on March 30, 2026, following months of governance debate and phased deployment. The release represents the most significant architectural overhaul since Aave V2 in 2020.
The headline change is the hub-and-spoke lending model. In V3, each deployment on each chain maintained its own isolated liquidity pools. In V4, a central 'hub' holds the core lending logic and liquidity parameters, while 'spoke' markets on different chains tap into shared liquidity through cross-chain messaging. This reduces fragmentation significantly — a position opened on Base can draw against liquidity provisioned on Ethereum mainnet.
V4 also introduces dynamic interest rate curves that adjust automatically based on market conditions, soft liquidations (partial collateral reduction rather than forced full liquidation), and a redesigned GHO stablecoin integration with native rate controls.
The 'Aave Will Win' governance package
Simultaneously with V4's launch, the Aave DAO passed a landmark governance package informally titled 'Aave Will Win' — a comprehensive value-accrual plan that ties AAVE token performance directly to protocol revenue for the first time.
The package routes 100% of net protocol revenue toward buying AAVE from the open market and distributing it to stakers in the Safety Module. Previously, protocol revenue primarily funded the DAO's operational treasury. Now, as Aave's fee revenue grows — currently running at approximately $180 million annualised — all of it returns to token holders.
Additionally, the package establishes a strategic reserve, reduces Safety Module staking requirements to improve capital efficiency, and sets targets for GHO's circulating supply to reach $1 billion by Q4 2026.
TVL milestone: $26 billion and counting
By the time V4 launched, Aave V3 had already grown to $26.18 billion in total value locked — making it not only the largest DeFi protocol by TVL but one of the largest financial applications on any blockchain ever.
Aave's dominance in lending is now substantial: it holds roughly 65% of all DeFi lending market share across its deployments on Ethereum, Arbitrum, Optimism, Base, Polygon, Avalanche, and other chains. Its nearest competitor, Morpho Blue, holds approximately $7.4 billion — less than a third of Aave's footprint.
The transition from V3 to V4 is gradual — the DAO voted for a migration program with incentives to shift liquidity, rather than a hard cutoff. V3 markets will continue operating alongside V4 for at least 12 months.
