Online reports that Aave, the loan agreement, posted a blog post saying that developers said that Aave V4 is expected to transform decentralized liquidity into DeFi's operating system. This model can empower the broader DeFi community and allow everyone to develop based on Aave rather than compete with it. Service providers and integrators can create professional service experiences while gaining sufficient liquidity to promote innovation within the Aave ecosystem rather than letting innovation be fragmented by market fragmentation." According to DeFiLlama, the total value (TVL) of Aave's locked positions on 19 blockchains exceeds US$45 billion. The project positions V4 as a new infrastructure layer in the DeFi space and plans to solve the start-up problem of "new markets having to compete with existing markets that have already been successful in order to compete for the same deposits." This model solves a core problem in the old version of the Aave protocol: liquidity was previously split into multiple small independent pools of funds. Under the V4 version, different markets can share the same larger shared capital pool, eliminating the need to build their own liquidity pools from scratch.
