Overview
Agglayer is Polygon’s interoperability layer. It connects chains so assets can move without wrapping, operations can be atomic across chains, and security is enforced through cryptographic proofs rather than trusted parties. CDK chains connect to Agglayer by default. Other chains can integrate independently. 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.
