Reinvestment Module - One of the standout features in @aave v4
🔹It solves a long-standing inefficiency in DeFi lending:
idle lender capital during periods of low borrowing demand.
🔹Instead of leaving excess liquidity untouched, Aave v4 routes it through the Liquidity Hub and automatically deploys it into low-risk external yield strategies.
🔹The module continuously monitors and rebalances, ensuring capital is keeping capital productive while ensuring liquidity can flow back instantly when borrow demand returns.
🔹The result:
• Lenders earn extra yield on top of standard lending interest
• Higher total returns without manual farming or active management
Aave v4 moves closer to capital-efficient DeFi where lending is about automated capital optimization.

Being still on development, Aave V4 is predicted to shake up DeFi lending with its brand-new mechanism design. One smart system is ready to set the higher standard for Aave as it withstands the reputation in terms of lending protocol.
Down here is a re-edit from the ghost itself to explore V4 (referred from the Aave blog)
1. Liquidity Hub or so called a “unified powerhouse”
In V4, liquidity is no longer split across separate markets. Instead, all assets are stored in a unified Liquidity Hub for each blockchain network.
The Hub operates behind the scenes as the central liquidity source while users interact with Spokes as their entry points. Key features include:
- Authorization control tracks which Spokes can access specific assets and enforces withdrawal limits
- Core accounting ensures total borrowed assets never exceed supplied assets
- Share-based tracking uses an efficient calculation
system that handles interest accumulation properly
This design fixes V3's biggest headache where assets stuck in one market couldn't help meet borrowing demand elsewhere. Now, all liquidity flows through the Hub, making the whole system more efficient, delivering better rates for both lenders and borrowers.
2. Specialized spokes
Spokes are the elements of V4 that act as user-facing interfaces and connect to the Liquidity Hub, each designed for specific use cases. Users supply and borrow assets through this component, not the hub. Think of them as specialized branches of a bank, each serving different customer needs.
