Polygon Chain
Public, permissionless settlement. Polygon Chain is the public Layer 2 network that serves as the default settlement layer for the OMS. It is open, permissionless, and production-proven at scale.- Sub-2-second finality
- Average transaction cost of $0.002
- $54B in stablecoin transfer volume
- 6.4B total transactions
- 159M unique wallet addresses
- Major integrations by Revolut, Stripe, Flutterwave, and more

Polygon CDK
Dedicated, compliance-grade blockchain infrastructure. For institutions that need their own rails, Polygon CDK lets you launch a production-ready rollup with custom throughput, fee structures, and compliance requirements.Why Polygon CDK
- 20,000+ TPS when optimized for payment workloads
- Rollup mode with pessimistic proof security via Agglayer, validium, or full zkRollup
- Granular network control: deploy as fully private or with gated access, API keys, and ACLs for read/write permissions
- EVM-equivalent: deploy existing smart contracts without modification; standard Ethereum tooling works without reconfiguration
- Execution clients: supports both op-geth and op-reth, giving operators flexibility in resource usage and performance tuning
- Implementation providers: Conduit and Gateway are building open source tooling and support both execution clients for production deployments
- Migration paths: zero-downtime migration for chains running Hyperledger Besu, preserving full data history
Agglayer connectivity
Cross-chain interoperability and unified liquidity are native features of every Polygon CDK chain. Agglayer provides shared state, cross-chain messaging, and trustless bridging across connected networks, without additional infrastructure. This means enterprise chains are not isolated: they can interoperate with Polygon Chain and other connected L2s from day one.Operating modes
| Mode | Description |
|---|---|
| Sovereign | Agglayer connectivity secured by pessimistic proofs. No prover required. Default configuration. |
| Validium | ZK-secured execution with offchain data availability via a DAC. |
| zkRollup | Fully onchain zero-knowledge rollup for maximum security and Ethereum-aligned trust. |
Who Polygon CDK is for
- Banks and financial institutions needing dedicated settlement infrastructure with compliance controls and public auditability
- Asset issuers that need custom compliance rules, token economics, or throughput requirements on dedicated chain infrastructure
- Enterprises and governments building payment infrastructure that requires a sovereign rollup with full control over sequencing, fee policy, and data availability
