Overview
Agglayer is a secure cross-chain bridge that connects the liquidity and users of heterogeneous blockchains in a single interoperability protocol so assets can move between them. It provides the secure foundation that the Open Money Stack uses for cross-chain payments. Agglayer is bundled with Polygon CDK: every CDK chain ships with Agglayer connectivity by default. Other chains can also integrate independently, and the network is no longer EVM-only: Miden joined as a non-EVM connected chain. What Agglayer provides:- Unified liquidity: Assets maintain their identity across connected chains. No wrapped tokens required.
- Atomic cross-chain operations: Transactions either succeed on all involved chains or fail entirely. No partial states.
- Mathematical security: Pessimistic proofs ensure a compromised chain cannot drain more than its own deposits. Damage is contained.
- Chain sovereignty: Connected chains keep their own architecture and governance. Agglayer adds interoperability without requiring changes to how a chain operates.
