Polygon CDK Unveils Institutional-Grade Privacy Chains With Full Access to Global Liquidity
Polygon CDK has launched a new institutional-grade privacy configuration using validium technology, allowing raw transaction data to remain within institution-owned infrastructure while settling on Ethereum via cryptographic commitments and zero-knowledge proofs. This upgrade targets banks and asset managers, enabling scalable confidentiality without sacrificing access to global liquidity and multi-chain networks. The system enhances privacy and security by preventing any single party from accessing full transaction data while maintaining public verification of chain integrity.
TLDR: Polygon CDK’s validium config keeps raw transaction data sealed within institution-owned infrastructure. Settlement on Ethereum uses only a cryptographic commitment and a ZK proof, never exposing transactions. Five composable privacy levels let institutions scale confidentiality without migrating between configurations. Private CDK chains connect to Agglayer, preserving access to Ethereum, multi-chain liquidity, and fiat ramps. Polygon CDK has announced a new privacy configuration for institutions building custom blockchains on its technology stack. The upgrade keeps raw transaction data inside institution-owned infrastructure. At the same time, chains built on the configuration retain open access to global liquidity networks. Powered by Succinct Labs’ SP1 Hypercube proving system, only a cryptographic commitment and a zero-knowledge proof settle to Ethereum. The configuration primarily targets banks, payments companies, and asset managers that are moving onchain. How the Privacy Configuration Works Polygon CDK now offers a validium configuration developed in partnership with Succinct Labs. Transaction data stays within an institution-operated data availability environment. Raw transaction data never reaches a public network. Ethereum receives only a cryptographic fingerprint and a validity proof for settlement. The SP1 Hypercube proving system is already live in production on Katana Network. Settlement relies on validity proofs rather than a trusted operator with data access. This approach means no single party holds visibility into the institution’s transaction data. The chain is verified publicly, but its transaction contents remain confidential. @0xPolygon stated: “Ethereum confirms the chain is operating correctly. It never sees the transactions.” Role-based controls gate RPC endpoints and block explorers through enterprise systems like Okta and Azure AD. Policies apply at the contract and function level. Counterparties view only their own transactions...
