Can you actually sell?
In one read-only call, a simulator contract buys the token from its deepest ETH or WETH pool on Uniswap V2, PancakeSwap V2, Uniswap V3 or Uniswap v4, sends some to a fresh wallet, and sells the rest back. It measures the buy, sell and transfer tax and the round-trip loss, which catches Uniswap v4 hooks that skim swaps without any token tax.
Nothing is deployed and no funds move: the simulator is injected into that one call. Its addresses are randomized on every scan, so a token can't whitelist it to pass the test.
