What the provider says
One-call verdict on any ERC20 on Base, Ethereum, Polygon, Arbitrum or Optimism: a machine-readable label for who can act on your balance (no-owner-powers, owner-can-intervene, owner-controls-balances, not-a-token), a headline, a plain-language reading and a paste-ready card - with the deterministic evidence underneath, selector by selector. Label, score and card come from the deployed bytecode and live state, never from a model. Research, not investment advice.

through it. See evidence levels.
