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 JSON list of smart contracts, each including address hash, contract name, verification status, compiler version, programming language, license type, market cap, coin balance, transaction count, proxy type, reputation, certification status, GitHub repository metadata, and pagination parameters for fetching the next page.
Example use cases
Auditing deployed contracts on Base
“Show me all verified smart contracts on Base chain (chain ID 8453) from Blockscout — I want to see which ones are certified and what compiler versions they're using.”
Searching for a specific contract by hash
“Look up the smart contract at hash 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum using Blockscout and tell me if it's verified, what language it's written in, and its transaction count.”
Discovering high-activity contracts on Polygon
“Find the top smart contracts on Polygon (chain ID 137) sorted by transactions count in descending order using Blockscout — I want to see which ones are most active.”
Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/smart-contractsWhen to prefer
Choose this endpoint when you need to browse, search, or filter verified smart contracts on a specific blockchain supported by Blockscout, especially when you need rich contract metadata like verification status, compiler version, reputation, and GitHub links. Prefer this over generic block explorers when cross-chain contract discovery or certified contract filtering is needed.
Side effects
- Invalid chain_id returns no results or 404 error
- Unrecognized filter or sort parameters may be ignored or return an error
- Pagination with invalid items_count or smart_contract_id may cause unexpected results
- Rate limiting may occur for high-frequency queries
- Chain not supported by Blockscout returns empty or error response
