Aave V4 Hub Spoke architecture brings shared liquidity, and capped Ethereum mainnet deployment to Aave’s next lending upgrade.
Author: Kritika Gupta
19th May 2026- Aave V4 is gaining traction in its capped Ethereum mainnet launch, and its biggest upgrade is the Aave V4 Hub Spoke architecture. The new design replaces fragmented lending pools with central Liquidity Hubs and modular Spokes, allowing Aave to share liquidity while isolating risk across different market types.
This two-layer model could improve capital efficiency, support specialized markets, and give Aave DAO tighter control over how new collateral, strategies, and risk segments scale.

@StaniKulechov Aave V4 isolated collateral hubs with capped liquidity sharing demonstrate refined risk architecture. Builders advancing modular design strengthen protocol resilience at growing scale.
Aave V4 is gaining momentum during its capped launch phase. One of its most compelling innovations is the new market structure: collateral is isolated across separate Hubs and further segmented into Spokes, creating a two-layer isolation model, while liquidity sharing within each https://t.co/ohBLyzpF9B

@StaniKulechov The hub-spoke model pools liquidity centrally while spokes customize risks, which should limit contagion better than V3's fragmented pools. Adding Babylon for native BTC collateral could pull in far larger un-wrapped holdings.

Steady attention without excessive speculation.
In previous versions, each Aave market operated as an independent pool. If a user wanted to supply assets on a “Core” market versus a “Prime” market on the same chain, the liquidity stayed completely separate. That structure limited capital efficiency and forced new assets to bootstrap their own liquidity from scratch. The Aave V4 Hub Spoke architecture separates liquidity management from market-level risk controls
Aave V4 collapses this into a layered system. At the center sit Liquidity Hubs, which hold all supplied assets and enforce global accounting rules. Users interact through Spokes, which are modular entry points connected to a Hub. Each Spoke defines its own collateral types, loan-to-value ratios, liquidation rules, and draw caps from the shared Hub liquidity.
This creates two layers of risk isolation. First, separate Hubs segment broad risk tiers. Second, Spokes within each Hub further isolate specific use cases with per-Spoke caps. As a result, the system contains contagion without sacrificing capital efficiency.
The current Aave V4 deployment on Ethereum runs three Hubs. The Prime Hub targets blue-chip and institutional-grade assets. The Core Hub handles general-purpose lending. The Plus Hub focuses on strategy-heavy stablecoin and Ethena-related activity.
Connected to these Hubs are 10 initial Spokes: Main, Lido e-Mode, EtherFi e-Mode, Kelp e-Mode, Lombard BTC, Gold, Forex, Bluechip, Ethena Ecosystem, and Ethena Correlates. Each Spoke operates with independent risk parameters and governed draw caps.
For example, the coreUSDT and coreUSDC Spokes each carry a draw cap of 200,000 units. The corefrxUSD Spoke has a tighter cap of 50,000 units. These conservative limits allow the protocol to gather real-world data before scaling.
The core problem Aave V4 addresses is liquidity fragmentation. In V3, spinning up a new lending market meant bootstrapping an entirely separate liquidity pool. That fragmented capital across markets and reduced utilization rates.
With V4’s Hub-and-Spoke model, new Spokes draw from a shared liquidity base. So a specialized market for liquid staking tokens can access the same underlying capital as a general-purpose market.
Aave V3 vs Aave V4 architecture differences
Aave Labs deliberately launched V4 with conservative parameters. All Hubs started with limited supply and borrow caps. Flash loans are not available at genesis. Dynamic liquidation bonuses and Hub-level interest-rate curves are active from day one.
The ARFC governance proposal that activated V4 on Ethereum passed with near-unanimous support from the Aave DAO. Before deployment, the codebase went through 345 cumulative auditor days across multiple firms, including a Sherlock audit contest and Certora formal verification.
According to the official blog, “V4 launches today with a deliberate set of initial markets, conservative caps, and a governance structure designed to scale responsibly.”
Aave V4’s current TVL sits between $40 million and $63 million, according to DefiLlama data. That figure is small compared to Aave’s protocol-wide TVL of approximately $14.5 billion, which remains dominated by V3 deployments.
No material migration from V3 to V4 has occurred yet. That is by design. The capped parameters deliberately limit inflows so the team can monitor the new architecture under real conditions before opening the gates.
The AAVE token trades near $88, with broader gains across 2025 and 2026 tied partly to V4 anticipation and Aave’s overall dominance in DeFi lending. No significant price spike occurred around the May 19 momentum update specifically.
Key milestones in Aave’s evolution from V1 to V4
It began as a decentralized lending protocol focused on pooled liquidity and overcollateralized borrowing.
The protocol added stronger capital efficiency, improved collateral tools, and more advanced lending mechanics.
It introduced multi-chain deployment, e-mode, isolation mode, portals, and more granular risk controls.
Aave Labs proposed a modular upgrade built around Liquidity Hubs and Spokes to reduce fragmentation.
Aave DAO approved the V4 Ethereum activation framework, including conservative launch parameters.
Multiple audits and formal security reviews were completed before the capped Ethereum deployment.
Aave V4 entered its capped Ethereum mainnet phase with Prime, Core, and Plus Hubs plus early Spoke markets.
Wider scaling, higher caps, more assets, and future expansion remain subject to Aave governance decisions.
Several questions remain open. Aave has not confirmed the timeline for multi-chain expansion beyond Ethereum. The mechanics of any V3-to-V4 migration path are not publicly detailed yet. When governance will lift the conservative caps also remains undecided.
Community sentiment on X, Discord, and governance forums is strongly positive. Builders and analysts praise the modular risk architecture. Retail users, meanwhile, focus on TVL growth and new monitoring tools like the Aave Pro wallet-watch feature.
Aave V4’s capped launch is a deliberate bet on patience. The 50% deposit growth during a phase designed to limit activity suggests the architecture is earning trust. If the Aave V4 Hub-Spoke architecture performs as expected under stress, it could set the template for how DeFi protocols manage risk and liquidity going forward.
