Polygon CDK Launches Privacy Upgrade, Institutions Can Build Private Chains and Access AggLayer
Polygon founder Sandeep Nailwal announced that Polygon CDK has completed a significant privacy upgrade, providing a new tech stack for financial institutions focused on privacy.
Institutions can now quickly launch private chains while seamlessly accessing the complete on-chain economy through AggLayer, achieving both privacy protection and high liquidity.
This upgrade is the result of a long-term open-source collaboration between the Succinct Labs team and Polygon, and both parties will continue to deepen their cooperation in the future.

Sandeep Nailwal has previously pushed for Polygon's transformation from a public chain to an institutional-grade solution. Since its launch, the CDK (Chain Development Kit) has become a core tool for many institutions to deploy custom chains. This privacy upgrade continues the long-term open-source collaboration with Succinct Labs on zero-knowledge proofs and is an important complement to Polygon's AggLayer interconnection strategy.
On the capital path, Polygon is concentrating ZK technology resources on privacy stack development, motivated by the need to eliminate financial institutions' core concerns about on-chain transparency. The private chain + AggLayer architecture allows institutional assets to remain confidential while enabling cross-chain transactions, attracting traditional asset management, banks, and RWA projects to shift funds from off-chain to the Polygon ecosystem, forming a closed-loop channel for institutional on-chain participation.
Similar to enterprise privacy chain layouts like Canton Network and Arc, the current Layer 2 and institutional chain industry is in a control phase of transitioning from a public chain transparency model to a privacy + interconnected hybrid architecture, with AggLayer becoming a key hub connecting private and public liquidity.
Essentially, this represents a reconstruction of the industry chain: the path for institutions to go on-chain is shifting from "either full transparency or full isolation" to "private privacy + shared liquidity." The mechanism lies in the CDK privacy upgrade and AggLayer's zero-knowledge interconnection technology, allowing financial institutions to participate in public market pricing and liquidity without sacrificing compliance privacy, accelerating the concentration of capital from traditional financial infrastructure to a hybrid on-chain system.

What institutions want most is never public transparency, but rather "my privacy + market liquidity." Privacy is not an island; when private chains can seamlessly connect to public chains, the barriers to going on-chain truly disappear.
The deeper the technical cooperation, the faster the adoption by institutions; whoever first packages privacy and liquidity for banks will take the next round of RWA pricing power.
