How this service works
Explore crypto activities with Blockscout's multichain search. Find transactions, addresses, tokens, and dapps across top blockchain networks — your go-to explorer for cross-chain blockchain data
Output
Returns an array of blob objects associated with the transaction, each containing: blob hash, raw blob data (hex-encoded), KZG proof, and KZG commitment — all fields relevant to EIP-4844 proto-danksharding validation.
Example use cases
Verify L2 rollup blob submission
“I need to verify that this Arbitrum transaction 0xabc123...def456 actually included its blob data on-chain — can you fetch the blobs and KZG commitments for it on chain ID 42161 using Blockscout?”
Debug EIP-4844 blob contents
“Can you retrieve the raw blob data for transaction 0x9f1e...a3b7 on the Base network (chain ID 8453) so I can inspect what the rollup submitted?”
Audit blob proof for data availability
“I want to audit the KZG proof and commitment for transaction 0x77dd...beef on Ethereum (chain ID 1) to confirm the blob was correctly committed — can you look that up on Blockscout?”
Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/transactions/%7Btransaction_hash_param%7D/blobsWhen to prefer
Use this endpoint when you need to retrieve EIP-4844 blob sidecar data (including KZG proofs and commitments) for a specific transaction on a supported blockchain. Ideal for developers auditing rollup data availability, debugging blob transactions, or verifying proto-danksharding submissions. Prefer this over generic RPC calls when you need structured blob data across multiple chains without managing your own node infrastructure.
Side effects
- Invalid or malformed transaction hash returns an error or empty result
- Chain ID not supported by Blockscout returns 404 or error
- Transaction exists but has no blobs (pre-EIP-4844 or non-blob tx) returns empty items array
- Network timeout if the chain node is slow to respond
- Payment failure (x402) if USDC balance is insufficient
