Risk check of a Base ERC-20 token from live chain state

Risk check of a Base ERC-20 token from live chain state: a buy, wallet transfer and sell simulated from fresh wallets through its pool router (honeypot flag, buy/sell/transfer tax), owner and renouncement, proxy and upgrade admin, mint/blacklist/pause/tax functions in the bytecode, Uniswap and Aerodrome pools with depth and USD price, and a 0–100 score listing each deduction, with a verdict. For pre-trade checks of a Base token. Facts and templates, not financial advice.
