PANews reported on November 20th that, according to the official blog, Aave announced the launch of its Aave V4 testnet and the open access to its codebase for public review. It has also deployed a developer preview version, "Aave Pro," a new interface for DeFi native users of the Aave network application. This allows the community to test new features and developers to experiment with implementations.

Aave V4 introduces a brand-new "Hub and Spoke" architecture. This architecture introduces several new design paradigms to Aave, each with its unique advantages. Funds are no longer dispersed across various markets on the same chain. Instead, all liquidity flows through "Liquidity Hubs".
