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 associated with the given address on the specified chain. Each transaction includes sender and recipient addresses (with ENS names, tags, scam flags, and contract metadata), transaction hash, value, fee, gas used and limit, gas price, priority fee, block number, timestamp, confirmation count, decoded input data, token transfers (with token details, amounts, and addresses), status, result, revert reason, raw input, exchange rate, and chain-specific data (e.g. Arbitrum L1/L2 fees, batch info, commitment/confirmation transactions).
Example use cases
Wallet activity audit for compliance
“Get me the full transaction history for wallet address 0x1234abcd... on Arbitrum using Blockscout, filtering for incoming transactions only, sorted from newest to oldest.”
DeFi portfolio tracking
“Show me all transactions made by 0xDeadBeef... on Base chain — I want to see the fees paid, token transfers, and the block number for each one.”
Smart contract interaction review
“Pull the transaction history for the smart contract at 0xAaBbCcDd... on Optimism so I can see which addresses have been calling it and what methods they've been invoking.”
Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/addresses/%7Baddress_hash_param%7D/transactionsWhen to prefer
Choose this endpoint when you need comprehensive, paginated transaction history for a specific address across any of Blockscout's supported chains. It is ideal when you need rich transaction metadata including token transfers, gas details, decoded inputs, chain-specific fields (e.g. Arbitrum batch data), and address reputation signals. Prefer it over generic RPC calls when you want structured, human-readable data with ENS resolution, scam flags, and public tags already enriched.
Side effects
- Invalid chain_id returns 404 or empty result
- Malformed address_hash_param returns 400 or validation error
- Address with no transactions returns empty items array
- Pagination cursor mismatch returns unexpected page
- Rate limiting or payment failure returns 402 or 429
- Chain temporarily unavailable returns 503
