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 Slither static-analysis findings categorized by vulnerability type (reentrancy, unchecked calls, arbitrary sends, etc.), the contract's proxy/upgradeability status, and an enumerated list of owner/role-gated privileged functions (mint, pause, blacklist, upgrade). Unverified contracts are rejected without charge.
Example use cases
DeFi deposit risk check
“I'm about to deposit USDC into a new yield protocol on Arbitrum — can you scan the contract 0x1234abcd...5678 on chain ID 42161 and tell me if there are any reentrancy vulnerabilities, admin backdoors, or upgrade mechanisms I should know about before putting in money?”
Token approval safety audit
“Before I approve this token 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Ethereum chain ID 1 to spend my funds, can you check it for security issues like unchecked calls, arbitrary sends, and whether anyone can pause transfers or blacklist my wallet?”
New DeFi protocol admin power review
“I'm evaluating a new Base (chain ID 8453) lending protocol at contract address 0xabcdef123456 — what privileged functions does the owner or admin have, like minting, upgrading the contract, or emergency pauses? Is it behind a proxy?”

Endpoint
GEThttps://contractlens-api.appin60.com/payability?utm_source=zero.xyzWhen to prefer
Choose ContractLens when you need pre-interaction security due-diligence on an EVM smart contract that is verified on Sourcify, especially before approving token spends, depositing funds, or trading a new token. It is uniquely suited for identifying Slither-detected vulnerabilities and owner/admin privilege mapping in one call. Prefer this over generic block-explorer lookups when you need structured security findings rather than raw bytecode or ABI inspection.
Side effects
- Contract not verified on Sourcify — rejected with an error and no charge applied
- Invalid or unsupported chain ID — returns an error indicating unsupported network
- Invalid contract address format — returns a validation error
- Contract call execution reverted — returns reason with 'contract call failed: execution reverted'
- Network/RPC timeout during static analysis — may return a timeout error
