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 a JSON object containing the batch number, before and after accumulator hashes, start and end block numbers, transaction count, data availability metadata, and the commitment transaction details (hash, status, timestamp, and block number on L1).
Example use cases
Verify Arbitrum batch commitment status
“Check if Arbitrum batch 1500 has been successfully committed to L1 — I need the commitment transaction hash and its status from Blockscout.”
Audit batch transaction count
“How many transactions were included in Arbitrum batch 300? Pull the full batch details from Blockscout so I can verify it matches our internal records.”
Inspect batch block range for debugging
“I need to find which block range Arbitrum batch 789 covers — give me the start and end block numbers from Blockscout so I can cross-reference with our node logs.”
Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/arbitrum/batches/%7Bbatch_number%7DWhen to prefer
Use this endpoint when you need detailed metadata about a specific Arbitrum batch by number — including its L1 commitment transaction, block range, and data availability. Prefer this over general transaction lookup endpoints when investigating Arbitrum L2 batch-level data, rollup sequencing, or cross-layer verification workflows.
Side effects
- Invalid or non-existent batch_number returns a 404 or empty response
- Unsupported chain_id returns an error or no data
- Network timeouts on heavily loaded chains
- Batch not yet committed may return incomplete commitment transaction fields
- Malformed batch_number (non-integer) causes a 400 bad request
