GoPlus Security Token Scanner

Skill by ara.so — Security Skills collection

Overview

GoPlus Security Token Scanner provides comprehensive security analysis for blockchain tokens and smart contracts. It detects honeypots, rugpulls, malicious code, and other security risks across multiple blockchain networks including Ethereum, BSC, Polygon, and more.

What It Does

• Token Security Analysis: Scans token contracts for common vulnerabilities and scam patterns
• Honeypot Detection: Identifies tokens with sell restrictions or hidden malicious code
• Contract Verification: Validates smart contract source code and ownership
• Liquidity Analysis: Checks liquidity pool status and lock information
• Trading Risk Assessment: Evaluates buy/sell tax, slippage, and other trading risks
• Multi-Chain Support: Works across Ethereum, BSC, Polygon, Avalanche, Arbitrum, and more

Core Features & Usage

Token Security Scan

Scan a token contract address for security issues:

import os
from goplus_security import GoPlusSecurity

# Initialize client
client = GoPlusSecurity(api_key=os.environ.get('GOPLUS_API_KEY'))

# Scan token on Ethereum
token_address = "0x1234567890abcdef1234567890abcdef12345678"
result = client.token_security(
    chain_id="1",  # Ethereum mainnet
    addresses=[token_address]
)

# Check results
if result['result'][token_address]['is_honeypot'] == '1':
    print("⚠️ WARNING: Honeypot detected!")
    
if int(result['result'][token_address]['sell_tax']) > 10:
    print(f"⚠️ High sell tax: {result['result'][token_address]['sell_tax']}%")

print(f"Contract verified: {result['result'][token_address]['is_open_source']}")
print(f"Owner address: {result['result'][token_address]['owner_address']}")

Multi-Token Batch Scan

Scan multiple tokens simultaneously:

# Batch scan up to 10 tokens
token_addresses = [
    "0x1234567890abcdef1234567890abcdef12345678",
    "0xabcdef1234567890abcdef1234567890abcdef12",
    "0x7890abcdef1234567890abcdef1234567890abcd"
]

results = client.token_security(
    chain_id="56",  # BSC
    addresses=token_addresses
)

for address, data in results['result'].items():
    risk_score = calculate_risk_score(data)
    print(f"{address}: Risk Score {risk_score}/100")

Contract Approval Scan

Check token approval security:

# Scan address approvals
approval_result = client.approval_security(
    chain_id="1",
    addresses=["0xYourWalletAddress"]
)

for approval in approval_result['result']:
    if approval['is_malicious'] == '1':
        print(f"⛔ Malicious approval detected: {approval['spender']}")
        print(f"   Token: {approval['token_symbol']}")
        print(f"   Amount: {approval['approved_amount']}")

NFT Security Check

Analyze NFT contract security:

# Scan NFT contract
nft_result = client.nft_security(
    chain_id="1",
    contract_address="0xNFTContractAddress"
)

nft_data = nft_result['result']
print(f"NFT verified: {nft_data['is_verified']}")
print(f"Malicious activities: {nft_data['malicious_behavior']}")
print(f"Contract owner: {nft_data['owner_address']}")

Common Patterns

Pre-Trade Security Check

def safe_to_trade(token_address, chain_id="1"):
    """Check if token is safe to trade"""
    client = GoPlusSecurity(api_key=os.environ.get('GOPLUS_API_KEY'))
    result = client.token_security(chain_id, [token_address])
    data = result['result'][token_address]
    
    # Red flags
    if data['is_honeypot'] == '1':
        return False, "Honeypot detected"
    
    if data['is_blacklisted'] == '1':
        return False, "Token is blacklisted"
    
    if int(data['sell_tax']) > 10:
        return False, f"High sell tax: {data['sell_tax']}%"
    
    if data['is_open_source'] == '0':
        return False, "Contract not verified"
    
    if float(data['holder_count']) < 100:
        return False, "Too few holders"
    
    return True, "Token appears safe"

# Usage
is_safe, message = safe_to_trade("0x1234567890abcdef1234567890abcdef12345678")
if is_safe:
    print("✅ Safe to trade")
else:
    print(f"⚠️ Risk detected: {message}")

Risk Score Calculator

def calculate_risk_score(token_data):
    """Calculate 0-100 risk score (higher = more risky)"""
    score = 0
    
    # Critical risks (30 points each)
    if token_data.get('is_honeypot') == '1':
        score += 30
    if token_data.get('is_blacklisted') == '1':
        score += 30
    
    # High risks (20 points each)
    if int(token_data.get('sell_tax', 0)) > 10:
        score += 20
    if token_data.get('cannot_sell_all') == '1':
        score += 20
    
    # Medium risks (10 points each)
    if token_data.get('is_open_source') == '0':
        score += 10
    if token_data.get('is_proxy') == '1':
        score += 10
    if float(token_data.get('holder_count', 1000)) < 100:
        score += 10
    
    return min(score, 100)

Automated Approval Revocation

def find_dangerous_approvals(wallet_address, chain_id="1"):
    """Find and report dangerous token approvals"""
    client = GoPlusSecurity(api_key=os.environ.get('GOPLUS_API_KEY'))
    result = client.approval_security(chain_id, [wallet_address])
    
    dangerous = []
    for approval in result['result']:
        if approval['is_malicious'] == '1' or approval['is_suspicious'] == '1':
            dangerous.append({
                'spender': approval['spender'],
                'token': approval['token_symbol'],
                'token_address': approval['token_address'],
                'approved_amount': approval['approved_amount']
            })
    
    return dangerous

# Usage
risky_approvals = find_dangerous_approvals("0xYourWalletAddress")
for approval in risky_approvals:
    print(f"Revoke approval for {approval['token']} to {approval['spender']}")

Troubleshooting

API Rate Limits

import time
from functools import wraps

def rate_limit_handler(func):
    """Handle API rate limits with exponential backoff"""
    @wraps(func)
    def wrapper(*args, **kwargs):
        max_retries = 3
        for attempt in range(max_retries):
            try:
                return func(*args, **kwargs)
            except Exception as e:
                if "rate limit" in str(e).lower():
                    wait_time = 2 ** attempt
                    print(f"Rate limit hit, waiting {wait_time}s...")
                    time.sleep(wait_time)
                else:
                    raise
        raise Exception("Max retries exceeded")
    return wrapper

@rate_limit_handler
def scan_token(address):
    client = GoPlusSecurity(api_key=os.environ.get('GOPLUS_API_KEY'))
    return client.token_security("1", [address])

Invalid Chain ID

SUPPORTED_CHAINS = {
    "eth": "1",
    "bsc": "56",
    "polygon": "137",
    "avalanche": "43114",
    "arbitrum": "42161",
    "optimism": "10"
}

def get_chain_id(chain_name):
    """Convert chain name to ID"""
    return SUPPORTED_CHAINS.get(chain_name.lower(), "1")

API Key Issues

Ensure your enterprise API key is properly set:

# Verify API key is loaded
echo $GOPLUS_API_KEY

# Test API connection
curl -H "Authorization: Bearer $GOPLUS_API_KEY" \
  "https://api.gopluslabs.io/api/v1/token_security/1?contract_addresses=0x..."

Best Practices

1. Always scan before trading: Never trade tokens without security verification
2. Check multiple metrics: Don't rely on a single indicator
3. Monitor continuously: Token security can change over time
4. Batch operations: Use batch scanning for efficiency
5. Cache results: Cache scan results for frequently checked tokens
6. Set alerts: Configure monitoring for portfolio tokens
7. Verify source code: Prioritize open-source verified contracts
8. Check liquidity locks: Ensure liquidity is locked long-term
