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 bundler's address details (hash, name, scam flag, metadata, proxy type, reputation, contract status, verification status, public/private tags, ENS domain, implementations, watchlist names), plus aggregate statistics: total_ops (total ERC-4337 user operations bundled) and total_bundles (total bundle transactions submitted).
Example use cases
ERC-4337 bundler reputation check
“Check the Blockscout bundler profile for 0x4337000c2828f5f11571c8e31334b3e9484cb7f5 on Arbitrum — is it verified, what's its reputation, and has it been tagged as a scam?”
Bundler activity analytics for a chain
“How many bundles and total operations has the bundler at 0xc0d3c0d3c0d3c0d3c0d3c0d3c0d3c0d3c0d30001 submitted on Optimism according to Blockscout?”
Cross-chain bundler identity lookup
“On Base mainnet, look up the bundler address 0x18Df82C7E422A42D47345Ed86B0E935E9718eBda on Blockscout and tell me its ENS domain, any public tags, and whether it's a proxy contract.”
Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/proxy/account-abstraction/bundlers/%7Baddress_hash_param%7DWhen to prefer
Use this endpoint when you need ERC-4337 account abstraction bundler-specific data (operation counts, bundle counts, reputation) for a known address on a specific chain. Prefer it over generic address lookup endpoints when the account abstraction context is critical — i.e., you need bundler-specific aggregates, not just token balances or transaction history.
Side effects
- Invalid or malformed address_hash_param returns an error response
- Unsupported or incorrect chain_id returns a 404 or empty result
- Address exists but has no bundler activity — returns zeroed stats
- Network timeouts for less-indexed chains
- Rate limiting if called without valid payment or excessively
