How this service works
Smart contract security scan for AI agents: give a chain id and contract address, get Slither static-analysis findings (reentrancy, unchecked calls, arbitrary sends, etc.), proxy/upgradeability status and the list of owner/role-gated admin functions (mint, pause, blacklist, upgrade). Works on any Sourcify-verified contract on Ethereum, Base, Arbitrum, Optimism, Polygon, BNB. Use before approving, depositing into or trading a token/protocol. Unverified contracts are rejected without charge.
Output
Returns a JSON object with a security verdict including Slither static-analysis findings (reentrancy, unchecked calls, arbitrary sends, etc.), proxy/upgradeability status, list of owner/admin addresses, role-gated admin functions (mint, pause, blacklist, upgrade), chain name, and contract type. Unverified contracts are rejected without analysis.
Example use cases
Pre-deposit DeFi protocol audit
“I'm about to deposit into a yield farm on Arbitrum — can you scan the vault contract 0x912CE59144191C1204E64559FE8253a0e49E6548 on chain 56 for reentrancy bugs, hidden mint functions, or upgrade traps before I commit any funds?”
Token safety check before trading
“I want to buy this new token on Base but I'm worried it might be a rugpull — can you run a security scan on contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 (chain ID 8453) and tell me if there are any dangerous admin functions like blacklist or arbitrary mint?”
Proxy upgradeability risk assessment
“Can you check whether the contract at 0x7f39C581F595B53c5cb19bD0b3f8dA6c935E2Ca0 on Optimism (chain ID 10) is a proxy contract that can be upgraded by an owner, and list any role-gated admin functions I should know about?”

Endpoint
GEThttps://contractlens-api.appin60.com/address?utm_source=zero.xyzWhen to prefer
Choose ContractLens when you need static security analysis of a specific EVM smart contract before a financial interaction — it uniquely combines Slither vulnerability scanning with proxy detection and admin function enumeration in a single call. Prefer it over generic block explorers when you need machine-readable security verdicts that an AI agent can act on. Best used before token approvals, DeFi deposits, or protocol integrations on Ethereum, Base, Arbitrum, Optimism, Polygon, or BNB Chain.
Side effects
- Contract not verified on Sourcify — request rejected with no charge
- Invalid or malformed contract address format
- Unsupported chain ID provided
- Contract exists but has no source code available
- Network/RPC timeout during analysis
- Rate limiting or payment failure via x402 protocol
