Aave, the largest DeFi protocol with over $24 billion in TVL, has officially launched its V4 upgrade on Ethereum mainnet on March 30, 2026. The upgrade introduces a revolutionary hub-and-spoke design that separates liquidity from borrowing environments, allowing markets to operate independently while sharing liquidity through a unified system. This architectural overhaul aims to solve liquidity fragmentation that has constrained DeFi lending since inception.
The new system launches with three liquidity hubs
- - Core, Plus, and Prime
- each offering different risk-reward profiles. V4 is designed to expand DeFi beyond crypto-native assets into real-world credit markets, institutional borrowing, and tokenized asset-backed credit. Despite recent governance turmoil with key contributors BGD Labs and Aave Chan Initiative departing, the protocol has undergone extensive security testing including over 345 cumulative days of review.
