Aave V4 went live on the Ethereum mainnet on March 30, 2026, 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 backed by real-world assets (RWAs) and fixed-rate credit products without splitting the existing liquidity pool.
Architectural Shift: Centralized Liquidity, Independent Risk
Previous iterations forced developers to choose between expanding into new markets and maintaining shared liquidity, pushing different risk profiles into a common pool or fragmenting liquidity across separate deployments. V4's hub-and-spoke model keeps core capital centralized while letting individual spoke markets operate with their own collateral rules and risk parameters.
Stani Kulechov, founder and CEO of Aave Labs, stated: "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 lending models." Aave currently holds billions in net deposits; V4 enables governance-controlled spokes to access that liquidity pool while isolating risk by collateral type and lending environment.
Initial Spoke Markets and Supported Assets
At launch, dedicated spoke markets from Lido, EtherFi, Kelp, Ethena, and Lombard are active. Supported assets include Tether's USDT and XAUT, Circle's USDC and EURC, Coinbase's cbBTC, Frax's frxUSD, and Paxos's USDG. Chainlink serves as the exclusive oracle provider across all V4 markets. Chainlink co-founder Sergey Nazarov called the launch a step toward connecting on-chain finance with global capital markets. Ethena CEO Guy Young attributed Aave's deep liquidity as foundational to Ethena's growth.
Security and Gradual Expansion
Before going live, V4 underwent third-party audits, formal verification, invariant testing, and a six-week public security contest involving hundreds of independent researchers. The initial deployment uses conservative parameters and limited scope to allow the system to stabilize under real market conditions before expanding. V4 is a superset of V3, retaining all earlier functionality while enabling a more modular design. Governance will observe liquidity behavior before gradually increasing credit lines and market types.
Alongside V4, Aave Labs launched Aave Pro, a new web interface for advanced users and the primary entry point to V4 markets at launch. Multi-chain deployment is under consideration, with Avalanche being evaluated given Aave's operational history and available liquidity there. Any expansion requires Aave DAO governance approval.
Revenue and Positioning
Revenue from Aave-branded products flows to the Aave treasury, funding development and security. The model aligns incentives among users, developers, and the protocol as new markets are introduced. Since its launch as ETHLend in 2017, Aave has become the largest DeFi protocol by total value locked (TVL). V4 positions it as credit infrastructure for on-chain financial markets rather than a standalone lending protocol.
