How this service works
Token security / honeypot detector for a Base mainnet ERC-20: EIP-1967/1822 proxy + upgradeability detection, bytecode dispatcher scan for mint/pause/blacklist/fee-setter/ownership selectors, owner() renouncement check, and a live eth_call state-override simulation testing whether a synthetic wallet can actually transfer() the token. Returns risk_score (0-100) + verdict (clear/review/block) + human-readable flags.
Output
A JSON object containing: token metadata (name, symbol, decimals, total supply), chain identifier, a list of human-readable risk flags, proxy details (is_proxy, admin address, implementation address, upgradeability), ownership info (owner address, type, renounced status), token capabilities (can_mint, can_burn, can_pause, has_blacklist, etc.), a honeypot simulation result with transferability status, an overall risk_score (0–100), a verdict string ('review', 'safe', 'risky'), and a timestamp of analysis.
Example use cases
Pre-swap token risk check
“Before I swap into this token at 0xabc123...def on Base, can you scan it for security risks? I want to know if it has a honeypot, blacklist, or if someone can pause transfers.”
DeFi portfolio due diligence
“I'm considering adding a new yield farm token on Base to my portfolio — the contract is 0x4d224452801ACEd8B2F0aebEF10b11a8B8e25b62. Can you give me a full security breakdown including the risk score, proxy setup, and any admin privileges?”
Detect rug pull indicators
“Is the token at 0x50c5725949a6f0c72e6c4a641f24049a917db0cb on Base a potential rug pull? Check whether the owner can mint unlimited supply, upgrade the contract, or freeze transfers.”
Technical details
Endpoint
GEThttps://x402-data-api.sigrunner.workers.dev/chain/token-securityWhen to prefer
Choose this endpoint when you need a rapid, on-demand security audit of any ERC-20 token on Base mainnet without API key setup. It is ideal for agents performing pre-trade due diligence, DeFi risk screening, or portfolio analysis pipelines. It is pay-per-call ($0.02 USDC) via x402, requiring no signup, making it well-suited for automated or infrequent lookups. Prefer alternatives if you need multi-chain support or deeper bytecode-level auditing.
Side effects
- Invalid or malformed token address returns an error — must be a valid 0x-prefixed 20-byte hex address
- Token not deployed on Base mainnet returns no contract data
- Honeypot simulation may return 'unavailable' if storage slot layout is non-standard
- Payment failure via x402 protocol results in 402 response with no data
- Rate limiting or worker timeout may return a 5xx error for complex contracts
