Aave DAO has officially launched the community discussion process for Aave V4 deployment by passing the Aave Request for Comment (ARFC) proposal vote. The proposal received 100% support on the governance platform, marking a crucial step towards a major upgrade for the protocol. The ARFC is a non-binding phase aimed at gathering community feedback and optimizing the solution, and will subsequently proceed to the formal on-chain Aave Improvement Proposal (AIP) vote and mainnet launch process. Aave V4 is expected to be deployed this year. This upgrade will introduce a new Hub and Spoke architecture, integrating liquidity through a unified Liquidity Hub and allowing multiple Spoke modules to define different lending rules, risk parameters, and collateral strategies, thereby improving capital efficiency and achieving more granular risk isolation. Furthermore, V4 will address the liquidity fragmentation issue in the existing protocol, support richer market structures, strengthen integration with the native stablecoin GHO, and upgrade the liquidation mechanism. Aave states that this architecture will evolve the protocol from a single lending model into a more flexible on-chain financial infrastructure, improving liquidity depth and risk pricing capabilities.
