TL;DR
- Aave V4 is now live on Ethereum, launching after the protocol processed more than $1 trillion in cumulative loans and captured over 50% of decentralized lending market share.
- V4 introduces a Hub and Spoke architecture, letting multiple specialized markets share one liquidity base instead of building deposits independently from scratch.
- The rollout includes Core, Prime and Plus Hubs, Aave Pro, and about 345 days of security review before mainnet launch.
Aave has launched V4 on Ethereum mainnet, turning years of design work into a live lending architecture built for a much larger market than DeFi currently serves today. What makes this release notable is not only that a new version is live, but that it arrives after Aave processed more than $1 trillion in cumulative loans. The protocol said it now holds over 50% of the decentralized lending market and has operated through every major stress event in DeFi’s history. That backdrop gives V4 the feel of an infrastructure upgrade, not a speculative experiment now.
Why the V4 deployment matters
The core change in V4 is its Hub and Spoke architecture. Aave is trying to replace isolated lending pools with a shared capital model that can support multiple specialized markets at once. In this setup, a central Liquidity Hub holds assets, while Spokes connect to it with their own collateral types, risk parameters and liquidation rules. When users supply through a Spoke, capital enters the shared Hub and becomes available across environments. That means institutional markets, liquid staking e-Mode strategies and dedicated ecosystems can draw from one liquidity base instead of building separate supplier networks.
Aave is also launching with a deliberately narrow and controlled footprint. The message from the rollout is clear: expand carefully, keep risk visible and let governance scale the system only after it proves itself in production. V4 went live on Ethereum with three Liquidity Hubs: Core, Prime and Plus. Core acts as the default venue with the widest asset coverage, Prime is aimed at suppliers seeking a more controlled collateral posture, and Plus is designed for strategy-heavy stablecoin activity. All three launched with conservative supply and borrow caps that the Aave DAO can later increase.
The release is also tied closely to a new interface built for this structure. Aave Pro is meant to make a complex architecture usable without forcing users to understand every moving part underneath it. The interface surfaces Hubs, Spokes, assets and rates in one place, while supporting supply and borrow activity from a unified account view. Aave said V4 underwent about 345 days of security review involving four audit firms, four independent researchers and a six-week public contest on Sherlock. For a protocol preparing to scale, that emphasis on security is part of the product.
