Pre-trade sellability / honeypot check for Base tokens: simulates a buy, a wallet transfer and a sell of a Base ERC-20 on live Base state (Uniswap v2/v3 or Aerodrome; nothing is signed or spent). Returns buy/sell/transfer success, measured tax %, revert reason and a simulation-driven verdict (ok/caution/avoid/unknown); owner/holder flags go in risk_flags. $0.02 USDC. Invalid input is not charged. Informational, not financial advice.
