Security x402 offerings

Token safety check before buying — is this token a honeypot or a rug pull? Bundles honeypot detection, buy/sell tax, holder concentration, LP lock and liquidity (GoPlus, Honeypot.is, DexScreener) into a single 0-100 token security risk score with a clear buy/avoid verdict. One call replaces three lookups. EVM chains.

Security audit for an EVM token: rug-pull, honeypot, and trading risk signals.

Token security audit and honeypot check, full report: EVM (Base, Ethereum, Arbitrum, Optimism, Polygon) simulated sell and buy, owner, proxy, mint/blacklist/pause/fee functions, liquidity, LP burn, tax; Solana mint and freeze authority, Token-2022 fee, permanent delegate, transfer hook, top-wallet share. Verdict (LOW_RISK, CAUTION, HIGH_RISK) and a 0-100 safety score. Use for due diligence.

Checks whether a token contract address is real, matches its claimed symbol, and whether its supply figures match an independent source (CoinGecko) — before trading, coding, or reporting against it. Catches hallucinated/wrong addresses, address-poisoning impersonation, and tokenomics hallucination.
