Polygon Chain Development Kit (CDK)
Polygon CDK (Chain Development Kit) an open-source toolkit that banks, fintechs, and other institutions use to launch their own private, compliant blockchain. Teams can build with it directly, or have Polygon work alongside them from chain design through production, and a managed partner can run it day to day. You own the chain and keep the economics, with no protocol fees or revenue share.
Polygon CDK comes in multiple configurations and each one is fully customizable to your technical and regulatory requirements. Keep client and transaction data on infrastructure you control to meet data residency rules, give auditors and regulators the visibility they need, and set access anywhere from open to fully private. Every chain is EVM-compatible and open source, so you avoid lock-in to a single vendor's stack.
CDK chains connect to other chains and to global liquidity through Agglayer, and they ship with the Polygon Open Money Stack. Wallets, fiat payins and payouts, and cross-chain routing come with the chain, so it plugs into the banking rails, payment networks, and liquidity your institution already relies on. You can move real money from day one, without a multi-vendor integration project in the way.
Key capabilities:
- Your chain, your control: You own the chain and set its rules, with access from open to fully private and no protocol fees or revenue share.
- Privacy that satisfies regulators: Keep client and transaction data on infrastructure you control, with selective-disclosure views for auditors and regulators.
- Flexible build options: Multiple configurations, including OP Stack and Hyperledger Besu, each fully customizable to your technical and regulatory needs.
- Built-in compliance: Real-time KYT, sanctions screening, and Travel Rule support, so your chain is ready for regulatory scrutiny from day one.
- Enterprise-ready access: Role-based permissions and single sign-on through the identity systems your teams already use.
- Connected to global liquidity: Link your chain to other chains and to global liquidity through Agglayer, without relying on third-party bridges.
- Plugs into existing financial infrastructure: Wallets, fiat payins and payouts, and cross-chain routing through Polygon Open Money Stack connect your chain to the banking rails and payment networks you already use.
