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 account abstraction factory contract objects, each including the factory's address hash, name, verification status, proxy type, reputation score, scam flag, ENS domain, public and private tags, implementation details, watchlist names, and total number of accounts created by that factory. Includes next_page_params for pagination.
Example use cases
Auditing AA factories on Optimism
“Give me all account abstraction factory addresses on Optimism from Blockscout, including how many accounts each one has deployed and whether they're verified contracts.”
Tracking smart wallet factory activity on Base
“I want to see which ERC-4337 factory contracts are active on Base — pull the full list from Blockscout with their total account counts, scam flags, and any public tags.”
Comparing factory deployment across chains
“Fetch the account abstraction factories on Arbitrum (chain ID 42161) from Blockscout so I can compare which factories have the most smart accounts deployed there.”
Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/proxy/account-abstraction/factoriesWhen to prefer
Use this endpoint when you need to discover and enumerate ERC-4337 / account abstraction factory contracts on a specific blockchain network, especially when you need metadata like verification status, scam flags, reputation, tags, and total account counts per factory. Prefer this over generic block explorers when you need structured, machine-readable factory data with pagination support across multiple chains via the Blockscout API.
Side effects
- Invalid or unsupported chain_id returns an error or empty result
- Unknown page_token causes a pagination error
- Rate limiting or payment failure returns 402 Payment Required
- Network-specific data unavailability returns empty items array
- Malformed query parameters return 400 Bad Request
