Aave, the largest DeFi lending protocol, has officialia launched V4 (version 4) of its platform on the Ethereum mainnet on Monday, introducing a modular hub-and-spoke architecture designed to address liquidity fragmentation in onchain credit markets.
The upgrade, which is the most significant architectural change since V1 and runs in parallel with the existing V3 deployment, centralizes asset supply in liquidity hubs while allowing individual spokes to operate with tailored risk parameters, collateral rules and liquidation logic.
Modular Hub‑and‑Spoke Architecture
According to Aave, V4’s new architecture is designed to scale into much larger and more diverse markets, including institutional, real-world assets and structured credit, by solving liquidity fragmentation.

This means that specialized lending markets can now inherit deep, unified liquidity from day one instead of bootstrapping their own pools.
Aave has facilitated more than $1 trillion in cumulative loans since inception and maintains over 50% of the decentralized lending market. However, the total addressable onchain credit market remains under 0.1% of global financial assets, according to the project’s documentation.
According to Aave developers, the hub-and-spoke design seeks to overcome the capital inefficiencies that arise when new or specialized markets must attract deposits independently.
Early Adoption Metrics
At launch, three liquidity hubs (Core, Prime and Plus) were activated with conservative supply and borrow caps. Spokes connected to these hubs include environments for correlated assets such as liquid staking tokens.
The rollout follows extensive audits and a competitive security review, with governance retaining control over future parameter adjustments and expansions.
Token Performance and Market Reaction
Since the V4 launch, the protocol’s native AAVE token has traded in a $96–$98 range, showing minimal intraday volatility.
On-chain metrics indicate that the total value locked (TVL) across Ethereum pools remains near $19.3 billion. According to DeFilamma, the TVL specifically in Aave V4 currently stands at $2.66 million.
Governance Challenges and DeFi Situation
Earlier this year, Aave faced governance tensions as key contributors left amid disputes over revenue allocation and DAO decision-making. These conflicts prompted multiple governance votes and revisions to protocol proposals, addressing integration choices and treasury management.
At the same time, the DeFi sector showed signs of cooling, with major tokens, including AAVE, trading in relatively narrow ranges and overall volatility declining. On-chain metrics indicated lower trading volumes and reduced speculative activity across lending and decentralized exchange platforms.
Why This Matters
The Aave V4 hub‑and‑spoke architecture allows new lending markets to tap shared liquidity from day one, avoiding the need to attract deposits separately. This enables institutional and RWA markets to operate efficiently with customized risk rules while using the same capital pool.

Aave V4 is the latest version of the Aave decentralized lending protocol on Ethereum, introducing a hub-and-spoke architecture to improve liquidity management and market efficiency.
The hub-and-spoke design centralizes liquidity in “hubs” while allowing individual “spokes” to operate with custom risk parameters, collateral rules, and borrowing limits.
Aave V4 supports standard crypto collateral, liquid staking tokens, and is designed to accommodate real-world assets and structured credit products over time.
