How to Detect Honeypot Tokens Before You Buy — A Developer Guide

What Is a Honeypot?

A honeypot token has hidden sell restrictions:

Sell taxes of 99%+
Blacklist functions
Owner-only trading
Upgradeable proxy contracts

Detecting Honeypots with Code

import httpx

API = "https://chainsight-api.onrender.com"

async def check_token(address: str):
    resp = httpx.get(f"{API}/v1/security/honeypot/{address}")
    data = resp.json()

    if data.get("is_honeypot"):
        print("🚨 HONEYPOT DETECTED — Do not buy!")
        return False

    risk = data.get("risk_level", "unknown")
    sell_tax = data.get("sell_tax", 0)

    if risk == "high" or sell_tax > 10:
        print(f"⚠️ High risk — Sell tax: {sell_tax}%")
        return False

    print(f"✅ Looks safe — Risk: {risk}")
    return True

Batch Check Multiple Tokens

addresses = ["0xtoken1", "0xtoken2", "0xtoken3"]

resp = httpx.post(f"{API}/v1/security/batch-check",
    json={"addresses": addresses})

for result in resp.json().get("results", []):
    status = "🚨" if result.get("is_honeypot") else "✅"
    print(f"{status} {result['address'][:10]}...")

Red Flags Before You Buy

Sell tax > 10% — Likely honeypot
Hidden owner — Contract modifiable post-deployment
No liquidity lock — Team can drain funds
Copy-paste contract — Same code as known scams
