How Astera Lend Works
Astera Lend revolutionizes DeFi lending through unified liquidity with isolated risk, enabling exotic collateral markets while maintaining capital efficiency and security. Unlike traditional protocols that fragment liquidity across separate markets, Astera Lend's architecture allows shared resources with independent risk management.
Core-Pool Architecture
Unified Liquidity Foundation
Core-Pool Concept: The Core-Pool accepts deposits of highly liquid, blue-chip assets (ETH, WBTC, USDC, USDT) and serves as the unified liquidity source for the entire protocol. Rather than each market maintaining separate liquidity, the Core-Pool extends credit lines to specialized Mini-Pools.
Mini-Pools Explained
Isolated Markets within Unified System
Mini-Pool Definition: Independent lending markets that can access Core-Pool liquidity while maintaining isolated risk parameters for specialized use cases.
Key Characteristics:
Independent Risk Parameters: Custom LTV ratios, liquidation thresholds, interest rates
Isolated Exposure: Failure in one Mini-Pool cannot affect others or Core-Pool solvency
Shared Liquidity: Access to Core-Pool assets without fragmenting liquidity
Specialized Collateral: Support for exotic assets without exposing Core-Pool
Traditional Approach:
Core Market: 10M ETH liquidity → Isolated
Isolated Market 1: 2M ETH liquidity → Isolated
Isolated Market 2: 3M ETH liquidity → Isolated
Total: Fragmented liquidity, reduced efficiency
Astera Approach:
Core-Pool: 15M ETH liquidity
Mini-Pool 1: 2M Core Pool ETH deposited → Shared efficiency, isolated risk
Mini-Pool 2: 3M Core Pool ETH deposited → Shared efficiency, isolated risk
Result: Higher utilization, better rates, exotic collateral supportMini-Pool Architecture
