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 ERC-4337 user operation, including details such as the operation status, sender smart account address, executed calls, paymaster info, and other relevant account abstraction metadata for the given chain.
Example use cases
Debug a failed smart wallet transaction
“I submitted a user operation from my smart wallet on Polygon and I'm not sure it went through correctly — can you look up operation hash 0xdeadbeef...1234 on chain 137 and give me a summary of what happened?”
Audit ERC-4337 paymaster activity
“As part of our security audit, can you fetch a readable summary of user operation 0x999aaa...5678 on Arbitrum (chain 42161) and tell me who the paymaster was and what was executed?”
Explain a user operation to a non-technical user
“My app processed a gasless transaction for a user — the operation hash is 0xfeed...cafe on Optimism chain 10. Can you get a plain-English summary of what that operation did so I can explain it to the user?”
Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/proxy/account-abstraction/operations/%7Boperation_hash_param%7D/summaryWhen to prefer
Choose this endpoint when you need a structured, human-readable summary of a specific ERC-4337 account abstraction user operation by its hash on a particular chain. It is ideal for debugging smart wallet transactions, auditing paymaster activity, or explaining gasless operations to users. Prefer this over general transaction lookup endpoints when the operation was submitted via a bundler and follows the ERC-4337 standard rather than a standard EOA transaction.
Side effects
- Invalid or malformed operation hash returns an error or empty response
- Unsupported chain_id results in a 404 or chain-not-found error
- Operation hash not yet indexed returns empty or not-found response
- Network timeout if the Blockscout node for the given chain is slow to respond
- Incorrect chain_id for the operation yields no results even if hash is valid
