## How to call it through Zero

```sh
zero fetch --capability canaryguard-smart-contract-honeypot-check-fe9df3fe
```

Example prompt: Before I buy this token, can you check if the contract at 0x4200000000000000000000000000000000000006 on Base (chain ID 8453) is a honeypot — specifically look for hidden transfer locks, blacklist modifiers, malicious fee hooks, or sketchy proxy upgrades?

## When to prefer this

Choose this endpoint when you need to audit a specific smart contract on the Base network for honeypot and malicious behavior patterns before interacting with it, trading a token, or integrating it into a DeFi workflow. It is purpose-built for Base chain contract security rather than being a generic multi-chain scanner, making it the best choice for Base-native token safety checks.

## Known failure modes

- Invalid or malformed contract address returns a validation error
- Contract not deployed on Base (chain ID 8453) returns a not-found or unverifiable error
- Unverified or minimal bytecode contracts may return inconclusive results
- Rate limiting or payment failure returns a 402 or 429 error
- Proxy contracts with obfuscated implementation slots may yield partial analysis

## How this service works

Audits Base smart contracts for hidden transfer locks, owner blacklist modifiers, unverified proxy upgrades, and malicious fee-on-transfer hooks.

## Output

Returns a structured audit report identifying whether the contract exhibits honeypot characteristics, including flags for hidden transfer locks, owner-controlled blacklist modifiers, unverified or upgradeable proxy patterns, and fee-on-transfer hooks that could trap buyers or extract unexpected fees.
