Aave V4 has officially launched on the Ethereum mainnet, marking the protocol's first major infrastructure overhaul in two years. The upgrade introduces a hub-and-spoke architecture that allows institutions to access loans collateralized by real-world assets (RWAs) and fixed-rate credit products without disrupting the existing shared liquidity pool.
Hub-and-Spoke: Unifying Liquidity While Isolating Risk
Previous versions of Aave forced developers to choose between expanding into new markets or maintaining a unified liquidity pool. This trade-off either pushed different risk profiles into the same pool or fragmented liquidity across separate deployments. The V4 hub-and-spoke model solves this by maintaining a central liquidity hub connected to multiple independent spoke markets, each with its own collateral rules and risk parameters.
“Aave V4 shifts the focus to the demand side—putting existing DeFi liquidity to work for real credit markets, from native crypto lending to tokenized assets, structured credit, and institution-specific loan models,” said Stani Kulechov, founder and CEO of Aave Labs. The protocol currently holds billions of dollars in net deposits, and V4 allows governance-controlled spokes to tap into that liquidity while keeping risk isolated by collateral type and lending environment.
The initial spokes include Lido, EtherFi, Kelp, Ethena, and Lombard. Supported assets cover USDT, XAUt (Tether's gold token), USDC, EURC, cbBTC, frxUSD, and USDG (Paxos). Chainlink serves as the exclusive oracle provider across all V4 markets.
Institutional-Grade Security and Gradual Rollout
Before deployment, Aave V4 underwent third-party audits, formal verification, invariant testing, and a six-week public security competition involving hundreds of independent researchers. The initial implementation uses conservative parameters and limited scope to allow the system to stabilize under real market conditions before expanding further. V4 is a superset of V3, preserving all existing functionality while enabling a more modular design.
Chainlink co-founder Sergey Nazarov called the launch “a key step toward connecting on-chain finance with global capital markets.” Ethena CEO Guy Young noted that Aave's deep liquidity has been foundational to Ethena's growth and described V4 as a “significant step forward.”
Aave Pro: A New Interface for Power Users
Alongside V4, Aave Labs launched Aave Pro, a new web interface designed for advanced users and the primary access point for V4 markets at launch. Multi-chain deployment is under consideration, with Avalanche being evaluated due to Aave's established track record and liquidity there. Any expansion will require approval from the Aave DAO governance.
Revenue from all Aave-branded products flows to the Aave treasury, funding development and security. This model aligns incentives among users, developers, and the protocol as new markets are introduced. Aave started as ETHLend in 2017 and with V4 positions itself as on-chain credit infrastructure for financial markets rather than a standalone lending protocol. As of writing, Aave is the largest DeFi protocol by total value locked (TVL).
