Celestia RPC Endpoint
Flat-rate Celestia RPC provider and Celestia RPC node access: free tier, no KYC, HTTP & WebSocket.
https://rpc.swiftnodes.io/rpc/celestia?key=YOUR_API_KEYwss://rpc.swiftnodes.io/ws/celestia?key=YOUR_API_KEYCelestia is a modular data availability (DA) network that orders transactions and guarantees their data is published, while execution and settlement run on rollups built on top of it. It introduced data availability sampling so light nodes can verify availability without downloading full blocks. SwiftNodes provides Celestia RPC across load-balanced nodes.

About Celestia
Celestia launched mainnet on October 31, 2023. It is built with the Cosmos SDK and CometBFT (Tendermint) consensus, and uses Namespaced Merkle Trees so rollups download only the data relevant to them. Light nodes use data availability sampling (DAS) to probabilistically confirm that block data was published.
Rollups post their transaction data to Celestia as blobs rather than executing on Celestia itself. The Ginger upgrade reduced block time to roughly 6 seconds; full DA confidence for light clients accrues as more samples are collected.
Common Use Cases on Celestia
- Data availability for rollups
- Sovereign rollup data posting
- Blob storage for modular chains
- Light-node data availability sampling
- Cheap off-chain data settlement
Celestia Ecosystem
Used as a DA layer by rollup frameworks and stacks including Arbitrum Orbit, OP Stack chains, Caldera, AltLayer, and Dymension RollApps.

Frequently Asked Questions: Celestia
How is Celestia queried?
Celestia exposes CometBFT RPC plus the Cosmos SDK REST and gRPC endpoints, and a dedicated node API for submitting and retrieving data blobs by namespace.
Does Celestia have an EVM chain ID?
No. Celestia is a non-EVM Cosmos SDK chain and does not use EVM chain IDs; it identifies networks by a Cosmos chain-id string (for example celestia for mainnet).
What are the TIA token decimals?
TIA uses 6 decimals; the base denomination is utia, where 1 TIA = 1,000,000 utia.
Does Celestia execute smart contracts?
No. Celestia provides ordering and data availability only; execution and settlement happen on rollups that post their data to Celestia.
Celestia guides from the blog
- Celestia RPC: Querying a Modular DA LayerCelestia isn't an execution chain — it's a modular data availability layer, so its RPC works nothing like Ethereum's. No eth_*, no smart contracts. Here's what Celestia actually does, the CometBFT RPC you connect to, how blobs and data availability sampling work, and where the celestia-node API fits in.
