Celestia Integrates With Polygon CDK

Celestia unveiled plans to integrate with Polygon’s Chain Development Kit (CDK), enabling developers to choose Celestia as their data availability (DA) layer for rollups built using Polygon CDK. The integration is scheduled to go live early next year. Polygon CDK is a developer stack for creating ZK-powered Layer 2 chains on Polygon 2.0. This integration adds Celestia's DA layer as a component within the Polygon CDK. According to Celestia, its DA layer can reduce transaction fees by up to 100 times through data availability sampling. Users of Polygon CDK chains will also be able to operate a Celestia light node, contributing to ensure data availability.
