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 JSON object containing a human-readable summary of the specified transaction, including details such as transaction type, status, involved addresses, token transfers, and other decoded activity relevant to the transaction hash on the specified chain.
Example use cases
Verify a DeFi swap transaction
“I just made a swap on Uniswap and the tx hash is 0xabc123...def456 on Ethereum mainnet — can you use Blockscout to summarize what that transaction actually did and confirm it went through?”
Debug a failed cross-chain transaction
“My transaction 0x9fe2...8c1d on Polygon (chain ID 137) seems to have failed — can you grab a summary from Blockscout so I can see what went wrong?”
Audit a token transfer for accounting
“I need a readable summary of transaction 0x7d3a...22fb on Base (chain ID 8453) for my records — can you look it up on Blockscout and tell me what tokens were transferred and to whom?”
Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/transactions/%7Btransaction_hash_param%7D/summaryWhen to prefer
Choose this endpoint when you need a quick, human-readable summary of a specific transaction on a supported blockchain network and already have the transaction hash. It is especially useful for multichain contexts where a single API covers Ethereum, Polygon, Base, Arbitrum, and other EVM-compatible chains. Prefer it over raw RPC calls when you want decoded, summarized transaction data rather than raw hex output.
Side effects
- Invalid or malformed transaction hash returns an error or empty result
- Unsupported chain_id results in a 404 or not-found response
- Transaction not yet indexed returns no data or a pending state
- Network timeouts on heavily loaded chains
- Paid endpoint returns 402 if USDC payment is not included
