How this service works
Smart contract verification and security analysis on Ethereum Base BSC Arbitrum Polygon
Output

Example use cases
Example prompt
“Can you verify and run a security analysis on the smart contract at address 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 on Ethereum mainnet and tell me if there are any known vulnerabilities or red flags?”
Technical details
Endpoint
GEThttps://contract.lonestaroracle.xyz/verifyWhen to prefer
Use this endpoint when you need to verify smart contract source code authenticity or perform a security scan on a contract deployed on Ethereum, Base, BSC, Arbitrum, or Polygon. Prefer this over generic blockchain explorers when you need a combined verification and security analysis in a single call with structured output.
Side effects
- Invalid or unrecognized contract address returns an error
- Unsupported blockchain network returns an error
- Unverified contract with no available source code may return limited results
- Rate limiting or payment failure returns 402 or 429
- Network RPC issues may cause timeouts for specific chains
