- The upgrade introduces unified Liquidity Hubs to replace fragmented markets.
- Spokes introduce modular loan setups with independent risk profiles.
- V4 aims to improve capital efficiency and unlock new possibilities for builders.
The lending protocol Aave is preparing one of its most significant upgrades to date.
Two days after launching a mobile savings app, the team released the upgrade’s testnet, signaling progress toward Aave V4 — an update designed to change how liquidity moves within the protocol.

V4 will replace the current multi-market structure with an innovative “Hub and Spoke” architecture.
The version 4 upgrade aims to transform decentralized lending by prioritizing developers who want to launch niche risk markets or experiment with assets that don’t fit neatly into Aave’s current model.
The official blog highlighted:
Each L1 or L2 will host at least one Aave V4 Liquidity Hub, with the option for multiple hubs per network. Hubs create room for broader experimentation within those ecosystems without liquidity becoming a limiting factor. This design simplifies support for new risk profiles and enables innovation without fragmenting liquidity, while also providing a method to seed liquidity for new Spokes.
To understand why V4 matters, it helps to review how Aave V3 works and the challenges that prompted the team to adopt a more flexible model.
Take a look at Aave V3
In Aave version 3, each market operates independently.
Deployments such as Ethereum Prime and Ethereum Core maintain their own asset lists and liquidity pools.
Users deposit into a specific market, and borrowing is limited to that market’s pool.
While this design helps isolate risk, it also creates material limitations.
Liquidity locked in one market cannot easily support loans in another.
Building new markets requires attracting capital from scratch.
That slows adoption and fragments the user base.
Governance becomes more complex, and experimenting is costlier because each distinct market needs its own pool.
The Aave team added:
It also limits economies of scale for lending and makes it harder to support new assets or implement unique loan configurations, which end up isolated and harder to use.
A unified Liquidity Hub to replace standalone markets
Version 4 overhauls the Aave lending ecosystem by introducing a Liquidity Hub: a shared pool that covers assets across the platform.
This innovative Hub serves as the single source of liquidity, ensuring borrowers and suppliers use the same capital base instead of segmented pools.
Crucially, users won’t interact directly with the Hub, although all deposits ultimately flow into it.
The Hub will handle interest calculations, accounting, and borrowing parameters.
Each L1 or L2 network can host at least one hub, with exceptions for chains that have specialized requirements or very high traffic.
The team expects this consolidation to significantly improve capital efficiency by reducing idle liquidity and improving borrowing conditions.
AAVE outlook
Aave’s native token showed notable selling pressure on today’s chart.
It fell more than 6% over the past 24 hours to $166.
A 27% drop in daily trading volume confirms a bearish sentiment around AAVE.
Its decline also mirrors broader market weakness.
The total global cryptocurrency market capitalization dropped over 4% in the last day to $3.04 trillion, as Bitcoin tumbled below $90,000 and traded at $89,478.
