After more than two years of development, the world's largest decentralized lending protocol Aave V4 has officially launched on Ethereum. This update introduces a brand-new "central radiating" architecture designed to create more flexible lending markets and support real-world credit products such as structured loans. CEO Stani Kulechov stated that the rollout will be tightly controlled, with initial operations managed by mainstream protocols like Lido and Ethena. The system features three liquidity centers, each with a clear risk level, and reduces risk by setting credit limits for each use case. V4 also includes a new re-investment module and deeper integration of the GHO stablecoin.
