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 JSON object containing the smart account's address details (hash, name, proxy type, reputation, scam flag, public/private tags, ENS domain, implementations), the factory address that deployed it, total user operation count, creation operation hash, creation timestamp, and creation transaction hash.
Example use cases
Smart wallet creation audit
“I need to find out when the smart account 0x1234567890abcdef1234567890abcdef12345678 was created on Polygon (chain ID 137) and which factory deployed it — can you pull that from Blockscout?”
ERC-4337 account reputation check
“Before I interact with this smart wallet 0xdeadbeefdeadbeefdeadbeefdeadbeefdeadbeef on Arbitrum (chain ID 42161), can you check Blockscout to see if it's flagged as a scam and what its public tags are?”
User operation activity summary
“How many user operations has the account abstraction wallet 0xaabbccddeeff00112233445566778899aabbccdd executed on Base (chain ID 8453)? Check Blockscout for me.”
Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/proxy/account-abstraction/accounts/%7Baddress_hash_param%7DWhen to prefer
Use this endpoint when you need ERC-4337 account abstraction specific metadata for a wallet address on a supported chain — particularly factory info, creation details, and user op counts. Prefer this over generic address lookup endpoints when you specifically need smart account/account abstraction context rather than standard EOA or contract data.
Side effects
- Invalid or non-existent address_hash returns empty or 404 response
- Unsupported chain_id returns an error or empty data
- Address is not an ERC-4337 smart account (returns no account abstraction data)
- Network timeout or upstream Blockscout node unavailability
- Malformed address hash (wrong format/length) causes a 400 error
