TechFlow News: On March 30, according to The Block, the decentralized lending protocol Aave V4 officially launched on the Ethereum mainnet after more than two years of development.
The core upgrade in V4 is the “Hub-and-Spoke” architecture: a Liquidity Hub serves as a centralized source of liquidity, extending credit lines to individual Spoke markets—each of which can independently configure risk parameters and lending environments. Initially, three Liquidity Hubs are deployed, corresponding to three risk tiers: Low-Risk (Prime), Risk-Adjusted (Core), and Risk-Return (Plus). Major onchain applications—including Lido, EtherFi, Kelp, Ethena, and Lombard—are scheduled to join as the first batch of Spokes.
Stani Kulechov, CEO of Aave Labs, stated that V4 aims to expand borrowing demand and channel onchain liquidity toward real-world economic use cases such as structured lending, fixed-rate borrowing, and tokenized asset-backed credit.
