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 paginated list of transactions in the specified block, each containing: transaction hash, from/to addresses (with ENS names, tags, contract status, reputation), fee breakdown, gas used/limit/price, transaction status, decoded input data, token transfers (with token metadata), timestamp, nonce, position in block, confirmations count, and chain-specific metadata (e.g. Arbitrum L1/L2 gas breakdown, batch number).
Example use cases
Audit block activity on Arbitrum
“Show me every transaction that was included in block 150000000 on Arbitrum — I want to see the sender, recipient, fees, and status for each one.”
Investigate a suspicious block on Base
“I have a block hash 0xd4e56740f876aef8c010b86a40d5f56745a118d0908a4a95e6c0ce0b21d5a9f on Base — can you fetch all transactions from that block so I can check for anything unusual?”
Monitor token transfers in a specific block
“Fetch all transactions from block 19000000 on Polygon using Blockscout and filter for token transfer types so I can track which tokens moved in that block.”
Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/blocks/%7Bblock_hash_or_number_param%7D/transactionsWhen to prefer
Use this endpoint when you need to enumerate all transactions within a specific block on any supported EVM-compatible chain. Prefer this over address-based transaction lookups when the unit of analysis is the block itself rather than a specific address or token. Particularly useful for block-level audits, MEV analysis, or reconstructing chain state at a specific height. The multichain support via chain_id makes it ideal for cross-chain tooling without needing separate explorer integrations per network.
Side effects
- Invalid chain_id returns 404 or empty results
- Non-existent block hash or number returns 404
- Malformed block hash format causes 400 bad request
- Pagination parameters out of range return empty items array
- Rate limiting or payment failure returns 402 or 429
- Truncated response if block has very high transaction count — requires pagination
