Polygon CDK
Build private blockchains. Connect to public liquidity. For institutions that need dedicated, private blockspace but also connection to broad crypto liquidity, Polygon Chain Development Kit (CDK) provides a composable, privacy-on-a-spectrum selection of features for financial institutions: custom throughput, compliance controls, and Agglayer connectivity bundled in. Work with Polygon to design and launch a bespoke chain; CDK is the product, not a self-serve kit. Every CDK chain is part of the wider Open Money Stack: bundled with non-custodial wallets, on- and off-ramps, stablecoin orchestration, and cross-chain interoperability, so your chain has access to the same payments infrastructure as Polygon Chain from day one.

​
Key capabilities

Privacy as a spectrum

Configure private validium, gated access, or fully sovereign blockspace. Privacy controls that institutions need without isolating from the broader ecosystem.

Connected via Agglayer

Every CDK chain ships with Agglayer connectivity, the secure cross-chain bridge that connects the liquidity and users of heterogeneous blockchains in a single interoperability protocol.

High performance

20,000+ TPS when tuned for payment workloads. 100+ Mgas/s capacity and managed uptime, with lower operational complexity than self-hosted alternatives.

Granular network control

API keys and access control lists let you filter read/write permissions and specific contract or RPC method calls. Deploy fully private or selectively gated.
