How to configure Keplr for Celestia light node? (Data Availability)

Keplr Wallet Integration with Celestia

1. Visit https://chains.keplr.app/ and locate Celestia under the “Cosmos Ecosystem” section.

2. Click “Add Chain” to automatically inject the network configuration, including RPC endpoints, chain ID (celestia), and coin denomination (utia).

3. Confirm the addition in the Keplr popup; no manual JSON editing is required for standard light node usage.

4. Once added, switch to the Celestia network within Keplr’s top-right network selector to enable transaction signing and balance visibility.

5. The wallet now supports direct interaction with Celestia’s data availability layer—submitting blobs, querying namespace commitments, and verifying DA proofs via connected dApps.

Running a Celestia Light Node via Keplr

1. A Celestia light node does not require local binary installation when using Keplr as a client interface—it leverages Keplr’s built-in light client protocol compliant with CometBFT’s header verification logic.

2. Keplr fetches block headers directly from public Celestia RPC endpoints such as https://rpc.celestia.publicnode.com or https://celestia-rpc.polkachu.com.

3. Data availability sampling (DAS) is performed off-chain by Keplr’s internal verifier: it randomly samples erasure-coded shares from published blocks to confirm full data publication without downloading entire blobs.

4. Namespace filtering is enabled through Keplr’s embedded namespace-aware query engine—users can restrict visibility to specific application namespaces like 0x00000001 (Celestia Core) or 0x01020304 (custom rollup).

5. No private key exposure occurs during DAS; all cryptographic checks—including Merkle inclusion proofs and RS code parity validation—are executed inside Keplr’s secure sandbox.

TIA Token Management in Keplr

1. After adding Celestia, Keplr displays TIA balances denominated in utia (1 TIA = 1,000,000 utia), reflecting staking, delegation, and blob fee settlements.

2. To pay for blob publishing, users must hold sufficient utia to cover base fee + priority fee—Keplr auto-calculates this based on current network congestion and namespace weight.

3. Staking is initiated directly from the Keplr dashboard: select “Stake” → choose a validator → enter amount → approve with signature.

4. Unbonding initiates a fixed 21-day cooldown period; Keplr shows precise unlock timestamps and pending rewards accrued in real time.

5. All staking actions emit signed Cosmos SDK messages compatible with Celestia’s ABCI++ interface, ensuring deterministic finality and cross-chain verifiability.

Data Submission Workflow Using Keplr

1. Developers embed Keplr injection logic into frontend dApps using the @keplr-wallet/types SDK to request blob submission permissions.

2. Users approve a BlobSubmit message containing raw bytes, namespace ID, and gas limit—Keplr signs without revealing plaintext content.

3. Signed transaction broadcasts to Celestia’s mempool via configured RPC; Keplr monitors inclusion in next available block header.

4. Upon confirmation, Keplr retrieves the block height and share root hash, enabling third-party verifiers to reconstruct the original blob using public erasure coding parameters.

5. Applications may then display DA confirmation status using green ✅ Verified badges powered by Keplr’s cached DAS results.

Frequently Asked Questions

Q: Does Keplr store my private key when interacting with Celestia’s DA layer?A: No. Keplr never transmits or stores private keys externally. Signing occurs locally in the browser extension’s isolated execution context.

Q: Can I submit blobs larger than 128 KiB using Keplr alone?A: Yes. Keplr handles automatic chunking and namespace-aligned padding for blobs up to 2 MiB, respecting Celestia’s current soft cap per transaction.

Q: Is namespace registration required before submitting data via Keplr?A: No. Celestia uses permissionless namespaces. Any 4-byte identifier may be used without prior registration or fee.

Q: Why does Keplr show different utia balances across RPC endpoints?A: This indicates inconsistent state sync among public RPCs. Always verify finality using at least two independent endpoints before treating a balance as confirmed.
