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
A paginated JSON object containing an array of transaction items, each with: from/to address details (hash, name, ENS domain, tags, contract status), transaction hash, fee breakdown, gas limit/used/price, raw and decoded input data, timestamp, block number, token transfers (with token metadata), transaction status, revert reason if applicable, and chain-specific fields like Arbitrum batch/commitment data. Also includes a next_page_params cursor for pagination.
Example use cases
Monitor DeFi activity on Arbitrum
“Show me the most recent transactions on Arbitrum — I want to see token transfers, the fees paid, and whether they succeeded or failed.”
Audit block transactions for compliance
“Get all transactions in block 19500000 on Ethereum from Blockscout and list the sender, receiver, value, and gas used for each one.”
Debug a failed smart contract call
“I think my transaction failed on Ethereum — can you look up recent transactions from my address using Blockscout and find any with a failed status or revert reason?”
Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/transactionsWhen to prefer
Use this endpoint when you need structured, rich transaction data across multiple blockchain networks from a single consistent API. Prefer it over chain-native RPC calls when you need decoded inputs, token transfer metadata, ENS names, address tags, or Arbitrum-specific batch data without running your own node. Ideal for cross-chain monitoring dashboards, compliance auditing, DeFi analytics, and transaction debugging.
Side effects
- Invalid chain_id returns 404 or empty result
- Invalid transaction hash format returns 400 bad request
- Unsupported filter value returns 422 validation error
- No transactions found for given block number returns empty items array
- Rate limiting or payment failure returns 402 or 429
- Pagination with stale cursor may return duplicate or missing items
