Profile a Base address in one call instead of four to six lookups. Returns contract or externally owned plus code size, proxy detection across all seven slot layouts including the legacy OpenZeppelin slot Base USDC uses, the resolved implementation, ERC-165 and behavioural ERC-20 detection, token metadata, requested ERC-20 balances, and denylist hits. Answers unknown rather than guessing, and null rather than false when a contract stays silent. Not a guarantee that an address is safe.
