Celestia and Polygon Labs have joined forces to integrate Celestia’s data availability layer with Polygon’s Chain Development Kit (CDK), signaling a significant advancement for Layer 2 projects within the Polygon 2.0 ecosystem. This collaboration is particularly beneficial for projects like OKX, Immutable, Astar, IDEX, and Palm Network, all of which operate as interoperating Layer 2 chains within the Polygon ecosystem.

Layer 2 networks, built using Polygon’s CDK, leverage zero-knowledge rollup technology, consolidating off-chain transactions onto the mainnet. The challenge lies in Ethereum's lack of a specific execution environment for its Data Availability (DA) layer, leading to on-chain processing and storage of data indefinitely, resulting in higher gas fees for Layer 2 solutions.

Celestia's innovative approach provides a solution to this challenge by offering storage bandwidth to multiple Layer 2 networks concurrently. This allows networks to operate light nodes and facilitates streamlined DA verification without overwhelming the network. In the words of Polygon co-founder Sandeep Nailwal, "Combined with interoperability and unified liquidity provided by Polygon 2.0, Celestia’s out-of-the-box solution will make creating new L2 chains as simple and affordable as deploying a smart contract."
