How this service works
Access to api/v2/addresses/:address_hash/transactions. List transactions involving a specific address with to-from filtering
Output
Returns a paginated list of transactions involving the specified address, each including transaction hash, block number, timestamp, from/to addresses, value transferred, gas fee, and transaction index. Supports cursor-based pagination via block_number, index, inserted_at, items_count, hash, and fee parameters.
Example use cases
Wallet transaction history audit
“Pull up all transactions sent from 0xAbCd1234...5678 on Polygon (chain ID 137) so I can audit what this wallet has been doing recently.”
Monitor incoming payments to address
“Get me the latest incoming transactions to my contract address 0x1234...abcd on Ethereum mainnet so I can see who has been sending funds to it.”
DeFi portfolio activity review
“List the most recent 50 transactions for address 0xBEEF...CAFE on Arbitrum (chain ID 42161), sorted descending by time, so I can review all recent DeFi activity.”
Technical details
Endpoint
GEThttps://api.blockscout.com/:chain_id/api/v2/addresses/:address_hash_param/transactionsWhen to prefer
Use this endpoint when you need a full or filtered transaction history for a specific address on any EVM-compatible chain supported by Blockscout. Prefer it over single-transaction lookups when you need to audit activity, monitor wallet behavior, or paginate through historical transactions. It supports to/from filtering, making it more flexible than generic block explorers for directional analysis.
Side effects
- Invalid address hash format returns 400 or empty results
- Unknown chain_id returns 404 or error
- Pagination parameters mismatch causes unexpected results
- Rate limiting or payment failure returns 402
- Address with no transactions returns empty list
- Network-specific endpoints may not support all chains
