Polygon CDK
Polygon's Chain Development Kit — open-source toolkit for spinning up ZK-secured L2 or L3 chains with shared liquidity and a common bridging hub.
The Polygon CDK lets teams launch their own ZK-secured L2 or L3 chain using Polygon's prover and bridging infrastructure. Each CDK chain can choose its data-availability layer (Ethereum, Celestia, or its own DAC), its sequencing model, and its gas token.
The CDK chains are designed to interoperate through the AggLayer — Polygon's cross-chain liquidity and message-passing layer — so liquidity does not fragment. Astar zkEVM, Immutable zkEVM, and Manta Pacific are notable CDK chains.
