# Multi-chain EVM Honeypot & Token Safety Screen

> Multi-chain EVM Honeypot & Token Safety Screen is a paid API for AI agents from evm-honeypot.frcompanycheck.workers.dev, paid per call via x402, $0.008/call, status unknown (last checked 2026-10-19).

Screens ERC-20 tokens across major EVM chains for honeypot risk, rug-pull signals, and trade feasibility via buy/sell simulation and liquidity checks

## 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 multi-chain-evm-honeypot-token-safety-screen-c2826333
```

Example prompt: Before my bot buys it, can you check if the token at 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48 on Ethereum is a honeypot — simulate a buy and sell, and tell me the taxes, liquidity, and overall verdict?

## When to prefer this

Use this endpoint when an AI trading agent needs a fast, pay-per-call safety screen before executing a token swap on Ethereum, Base, Arbitrum, Optimism, Polygon, or BSC. Prefer this over general smart contract auditors when you need a quick, simulation-based honeypot and tax check rather than a full audit. Ideal for automated trading pipelines where per-call x402 micropayments are acceptable and where multi-chain coverage without API key management is preferred.

## Known failure modes

- Invalid or non-existent contract address returns error or empty result
- Unsupported chain identifier causes routing failure
- Token with no DEX liquidity may produce inconclusive simulation results
- Public RPC rate limits or downtime may cause timeouts
- Proxy contracts with upgradeable logic may produce misleading verdicts
- Very new tokens with no liquidity pairs may fail simulation
- Payment failure via x402 USDC on Base blocks the request

## How this service works

Pay-per-call multi-chain ERC-20 honeypot and rug-risk screen for AI trading agents on ethereum, base, arbitrum, optimism, polygon, bsc. Owner/proxy/dangerous bytecode, DEX V2 liquidity, buy-transfer-sell eth_call simulation with taxes. Public RPCs only. x402 USDC on Base.

## Output

Returns a JSON object with the chain, token symbol, contract address, a verdict label (e.g. ORANGE, RED, GREEN), a passes_filter boolean, and a checks object containing can_buy, can_sell, sell_tax_pct, owner_renounced, and liquidity_native values derived from eth_call simulation against public RPCs.
