what's AggLayer?
AggLayer is an interoperability protocol developed by Polygon Labs designed to unify liquidity and state across heterogeneous blockchain networks. It enables chains—starting with Polygon CDK chains and expanding to others like Polygon PoS—to connect securely via shared state proofs and security models such as optimistic and pessimistic proofs. This allows for fast cross-chain interactions, targeting sub-10-second finality, without requiring chains to rewrite their core architecture. The protocol supports multi-stack flexibility, ZK-based identity solutions, and enterprise-focused tools like CDK Enterprise for Ethereum-aligned rollups. It powers an "Open Money Stack" for seamless onchain value transfer, yield generation, and financial services, bridging public and permissioned environments while maintaining compliance and control.
AggLayer integrates Trails for cross-chain payment orchestration using intents within Open Money Stack.
