# GoPlus Security Token Scanner > Skill by [ara.so](https://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: ```python 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: ```python # 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: ```python # 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: ```python # 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']}") ``` ## CLI Usage ### Command-Line Scanner ```bash # Basic token scan goplus-scanner scan --chain eth --address 0x1234567890abcdef1234567890abcdef12345678 # Scan with detailed output goplus-scanner scan --chain bsc --address 0xABC123 --verbose --output json # Batch scan from file goplus-scanner batch-scan --chain eth --input tokens.txt --output report.json # Check wallet approvals goplus-scanner check-approvals --chain eth --wallet 0xYourWallet # Generate security report goplus-scanner report --address 0xTokenAddress --format pdf --output security-report.pdf ``` ### Advanced CLI Options ```bash # Set custom risk thresholds goplus-scanner scan --address 0xABC123 \ --max-buy-tax 5 \ --max-sell-tax 5 \ --min-liquidity 100000 # Monitor token continuously goplus-scanner monitor --address 0xABC123 --interval 300 --alerts telegram # Export scan history goplus-scanner export-history --days 30 --format csv ``` ## Common Patterns ### Pre-Trade Security Check ```python 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 ```python 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 ```python 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 ```python 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 ```python 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: ```bash # 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
