# SML Token Verdict: on-chain token and contract risk check

Send a token/contract address (Base, Ethereum, BSC), get a deterministic verdict (LOW_RISK / CAUTION / HIGH_RISK / HONEYPOT / NOT_A_CONTRACT) with risk score, confidence and per-check reasons: buy/sell honeypot and tax simulation, ownership/renounce, EIP-1967 proxy, mint/blacklist/pause/fee admin functions, DEX liquidity and pool age. Synchronous, ~1s, with an Ed25519-signed hash-chained receipt anyone can verify. Research, not advice.
