Token Preflight (Base)

A pre-trade safety check for Base ERC-20 tokens, built for AI agents. Send a token address, get an evidence-based verdict card: a simulated buy then sell (honeypot and tax detection), owner powers, proxy/upgradeability, source verification, liquidity, LP burn, holder concentration and token age.

How labels work

Every label is a factual, reproducible signal with evidence (for example “sell failed in simulation” or “privileged mint function”), never a judgement about anyone’s intent. Grades: OK, CAUTION, DANGER (critical signal such as a failed sell or a tax of 50%+), UNKNOWN (not enough data).

Not investment advice. Token Preflight reports automated, point-in-time technical observations from public on-chain data and a simulated (never broadcast) buy and sell. It does not judge the intent or honesty of any project or person, can miss risks, and can be wrong. Labels describe observed signals, not conclusions. Do your own research before trading.
