## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability contractlens-smart-contract-security-scan-b04ffdb1
```

Example prompt: Before I deposit into this protocol, can you run a full security scan on the contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum (chain ID 1) — I want to know about any reentrancy issues, unchecked calls, proxy setup, and who controls the admin functions like mint or pause?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
