Polygon Cdk protocol
Overview
Polygon CDK (Chain Development Kit) is a software toolkit for launching custom layer-2 blockchains that use zero-knowledge proofs. It allows developers to build application-specific ZK-rollups that can inherit security from Ethereum and maintain interoperability with the Polygon ecosystem. While Polygon's own zkEVM rollup network is being sunset (mainnet sequencer ended July 2026), Polygon has confirmed CDK chains are unaffected, with the CDK and AggLayer stack remaining the focus for cross-chain settlement (as of 2026-07-15).
Within the DeFi Intel graph, Polygon Cdk connects to 3 tracked entities, most strongly to Polygon Labs, Polygon zkEVM, Agglayer.

Frequently asked questions
What is Polygon Cdk?
Polygon CDK is a modular, open-source framework for creating and deploying ZK-rollup chains that settle on Ethereum.
How does Polygon CDK differ from Polygon PoS?
CDK is a toolkit for building new chains, not a single network; it uses zero-knowledge proofs for validity, unlike Polygon PoS which uses a proof-of-stake sidechain model.
What customizability does Polygon CDK offer?
Developers can choose execution environments (zkEVM or other), data availability modes, tokenomics, and bridge configurations.
What is Polygon Cdk connected to?
In the DeFi Intel knowledge graph, Polygon Cdk is linked to 3 other tracked entities, most strongly to Polygon Labs, Polygon zkEVM, Agglayer.
