Celestia, Polygon Labs’ chain development kit (CDK) with open source code base used to develop Layer 2 chains.
This integration will provide a dedicated data availability solution for Layer 2 projects using Polygon CDK, such as OKX, Immutable, Astar, IDEX, Palm Network, and others.

It aims to reduce gas fees for these projects, which are part of Polygon 2.0, a claimed ecosystem of Layer 2 chains that can interact with each other.
Layer 2 networks developed on Polygon’s CDK use zero-knowledge rollup technology. They aggregate transactions off-chain and finalize them in batches on the main chain.
However, these chains require data availability verification. This means ensuring that every network member can securely retrieve and validate the data stored off-chain.
A challenge arises because Ethereum, the platform that these chains rely on, lacks a dedicated execution environment for the DA layer.
As a result, Ethereum nodes need to process and store data on-chain indefinitely, which contributes to the higher fees of Layer 2 solutions. This is where data availability solutions can come in.
Celestia’s strategy includes its own data availability solution that can provide storage bandwidth for multiple Layer 2 networks simultaneously. This solution, which allows networks to run light nodes, makes DA verification easier without creating too much of a burden on the network.
Sandeep Nailwal, co-founder of Polygon, said, “Combined with the interoperability and unified liquidity provided by Polygon 2.0, Celestia’s turnkey solution will make creating new L2 chains as simple and affordable as deploying a smart contract.”
What is Celestia?
Celestia is a modular blockchain network and because it decouples the consensus mechanism, it allows anyone to easily create their own private blockchain, without the hassle of launching a new consensus network. These blockchains on Celestia operate simultaneously, independently, and securely.
