Aave Labs has announced the official launch of Aave V4 on the Ethereum mainnet. According to Foresight News, the new version introduces a 'Hub and Spoke' architecture, which centralizes asset management through a Liquidity Hub and allows various Spokes to connect with specific collateral types, risk parameters, and liquidation rules. Additionally, Aave Pro, an interface designed for V4, has been launched to enable users to manage positions across Hubs and Spokes within a unified account view. Currently, V4 has initiated three liquidity hubs on Ethereum: Core Hub, Prime Hub, and Plus Hub, with conservative supply and borrowing limits set initially.
