Mini Pools
Mini Pools represent Astera Lend's breakthrough innovation: isolated lending markets that access shared liquidity. This architecture enables support for exotic collaterals, experimental strategies, and specialized use cases without compromising the security of Core Pool depositors or fragmenting protocol liquidity.
Isolated Market Creation
Independent Market Architecture
Mini Pool Structure: Each Mini Pool operates as a complete lending market with independent parameters while accessing Core Pool liquidity through credit lines:
