@retardedguru Unified Liquidity Layer means part of the architectural improvement on Aave Protocol, where liquidity exists in a dedicated (consolidated) layer, whereas other business logic (such as borrow module or liquidation engine) is plugged into the liquidity layer. This modular approach gives more flexibility to expand the protocol over time or support future upgrades with the less need for liquidity migrations. Mind that multiple liquidity layers can be supported to cater different use-cases.
Cross-Chain Liquidity Layer focuses on liquidity movements between markets that are deployed on different networks. CCLL means an improved version of the Aave portals.
