🧪 Token Safety Scanner

Real-time honeypot detection for Base chain tokens — before you buy

Paste any Base ERC-20 token address and get a full security analysis: proxy detection, bytecode risk-selector scan, ownership checks, and a live on-chain transfer simulation. Built for traders, degens, and AI agents who need to know before they click "swap".

What it detects

🔄 Upgradeable Proxies

EIP-1967/EIP-1822 transparent & UUPS proxies — can the contract logic be swapped out from under you?

✋ Mint, Pause & Blacklist

Can the owner mint unlimited new supply, freeze transfers, or block specific holders?

🏠 Ownership Status

Is the contract renounced? Multi-sig? EOA-controlled? Who can change the rules?

💰 Live Transfer Simulation

We simulate an actual eth_call transfer — does it succeed, revert, or silently burn your tokens?

📊 Risk Score & Verdict

Aggregated 0-100 risk score with clear/review/block verdict and human-readable flag explanations.
