Token safety check on Base before buying: honeypot, rug pull and scam detection. Verdict SAFE/CAUTION/SCAM with fixed reason codes and action ALLOW/BLOCK/RECHECK; admin rights, sell tax, liquidity, two independent honeypot sources plus own sale simulation of a real holder (Uniswap v4 included), check coverage and block number

The grounded council: we buy the facts first, then deliberate on them. Your question is scanned for a contract address, URL or $TICKER; we spend on the matching evidence (honeypot simulation, sanctions screen, page content, SEC profile), hand it to one analyst that judges on what was found, not on recollection. The response lists every source and what we spent for you.
