Polygon CDK
Polygon CDK lets institutions deploy their own custom blockchain on production-ready rollup infrastructure. Every CDK chain connects to Agglayer by default, so cross-chain interoperability and unified liquidity are built into the infrastructure from day one — not a separate integration. CDK provides enterprise-grade blockspace with predictable costs, privacy options, performance under load, and uptime guarantees, purpose-built for institutions that need compliance controls without sacrificing connectivity.

​
Key capabilities

Built-in Agglayer interoperability

Every CDK chain connects to Agglayer by default. Cross-chain asset transfers and unified liquidity are native features — no additional bridging infrastructure required.

High performance

20,000+ TPS when optimized for payment workloads. 100+ Mgas/s throughput. Managed uptime SLA with lower maintenance complexity compared to Hyperledger Besu setups.

Granular network control

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

Zero-downtime migration

Migration pathways for chains running Besu, preserving full data history without business disruption.
