🧠 A flexible, chain-agnostic tool to detect risky EVM token contracts using custom RPC and explorer config.

🚀 Installation

npm install token-sniffer-lite

⚙️ usage

import { sniffToken } from "token-sniffer-lite";

const config = {
  rpcUrl: "https://bsc-dataseed.binance.org/",
  explorerApiKey: "YOUR_BSCSCAN_API_KEY",
  explorerApiBase: "https://api.bscscan.com/api",
  chainName: "bsc" // Optional
};

const address = "0xabc123..."; // Token contract address

const result = await sniffToken(address, config);

console.log(result);

What it Checks

| Feature            | Description                                                               |
| ------------------ | ------------------------------------------------------------------------- |
| `isVerified`       | Checks if contract is verified on explorer (Etherscan, BscScan, etc.)     |
| `canMint`          | Flags if the contract has public minting functions                        |
| `hasBlacklist`     | Checks for blacklist functions that can restrict users                    |
| `hasHiddenFees`    | Flags presence of tax/fee setter functions (`setFee()`, `setTax()`, etc.) |
| `honeypotRisk`     | Simulates a `transfer()` to detect honeypots (buy-only traps)             |
| `ownerControlsAll` | Owner has permission to mint, blacklist, tax, etc.                        |
| `isRenounced`      | Checks if contract ownership has been renounced                           |
| `liquidityLocked`  | 🔧 Not implemented yet — will check LP lock/burn                          |
| `score`            | Final score out of 100 (higher = safer)                                   |
