TechFlame news: Stani Kulechov, founder and CEO of the decentralized lending protocol Aave, posted a response to several claims about Aave V4. He said that Aave V4's Hubs and Spokes are isolated by risk profile by default, and risk-adjusted markets can share liquidity through the Hub within set caps to support new use cases while avoiding unnecessarily fragmenting liquidity. He believes that fully isolating liquidity often fragments capital, lowers utilization, and raises user costs, especially after the incentives used to bootstrap liquidity end. Stani said that in V4, Spokes represent lending markets, and Hubs can share liquidity across these markets, enabling isolated risk profiles to use the liquidity pool, thereby improving utilization and capital efficiency. Unlike curated vaults, which usually start from zero liquidity and require capital or incentives to bootstrap, V4 Spokes can rely on the entire Hub balance sheet from day one. He also said that the V4 architecture is simpler and remains flexible, with the overall codebase significantly smaller than Aave V3. According to him, Aave V4 has secured $1.2 billion in deposits and is deployed across multiple networks including Ethereum, Avalanche, and Arc. V4 already supports third-party curators such as EtherFi. Curators can build and manage full market structures and participate in the economic distribution of the broader lending market, rather than only charging fees on deposit management scale.
