This upgrade introduces an integrated liquidity hub to replace fragmented markets. Spokes introduces a modular loan setup with independent risk. V4 aims to increase capital efficiency and open new horizons for developers.
Lending protocol Aave is preparing one of its most ground-breaking upgrades.
Two days after announcing the mobile savings app, the team released a testnet of the update, showing progress towards Aave V4, which aims to change the way liquidity is moved within the protocol.

V4 replaces typical multimarket systems with an innovative, integrated “hub and spoke” architecture.
The version 4 update aims to transform how decentralized finance lending works, prioritizing developers looking to launch risk markets or experiment with assets that don’t fully fit Aave’s current structure.
The official blog highlights:
Each L1 or L2 has at least one Aave V4 liquidity hub, and there can be multiple hubs per network. Spokes allow us to experiment more within these ecosystems without liquidity becoming a limiting factor. This design makes it easier to support new risk profiles and allows for innovation without fragmenting liquidity, while also providing a way to bring liquidity to new spokes.
To understand why the V4 upgrade is important, let’s take a look at how Aave V3 works and the challenges that led teams to seek a flexible model.
Aave V3 overview
In Aave version 3, each market functions independently.
Deployments like Ethereum Prime and Ethereum Core maintain their own asset list and liquidity pool.
Individuals can only supply and borrow from a well-defined market.
Although this structure helps isolate risk, it introduces some important limitations.
For example, liquidity stuck in one market cannot support borrowing in another market.
Also, building a new market requires raising money from scratch.
This fragments your entire user base and slows adoption.
Additionally, each market requires its own pool, making governance difficult and experimentation heavier.
The Aave team added:
It also limits borrowing economies of scale, making it difficult to support new assets or implement unique borrowing structures, resulting in silos and difficulty in use.
An integrated liquidity hub to replace separate markets
Meanwhile, version 4 overhauls the Aave lending ecosystem with a liquidity hub, a shared pool that comprises assets across the platform.
The innovative hub acts as a single source of liquidity, ensuring that borrowers and suppliers can leverage the same capital base instead of a segmented capital base.
Most importantly, all deposits end up going to the hub, but users never interact with the hub directly.
The hub handles everything, including interest calculations, accounting, and borrowing limits.
Each L1 or L2 platform can host at least one hub, except for chains with special needs or heavy traffic.
The team expects this combination to significantly improve capital efficiency by reducing idle liquidity and improving borrowing conditions.
AAVE outlook
Aave’s native token showed significant selling pressure on the daily chart.
It fell more than 6% in the past 24 hours to $166.
The 27% decrease in daily trading volume supports the bearish sentiment on AAVE.
Meanwhile, its downward stance is consistent with broader weakness.
The global cryptocurrency market capitalization fell more than 4% to $3.04 trillion a day earlier, as Bitcoin plummeted below $90,000 and traded at $89,478.
